Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of paint mixing, in particular to a paint mixing device. BACKGROUND

[0002] Paint is a viscous liquid prepared by resin, oil or emulsion as the main component, with or without pigments, fillers and corresponding additives, and with organic solvents or water, which is widely used in the field of construction.

[0003] Currently, paint is stored in a paint bucket. When not used for a long time, the paint will precipitate, so the paint needs to be mixed before use. In the prior art, the paint bucket is clamped and fixed by a mixing device, and then the paint bucket is constantly shaken by a shaking structure to fully mix the paint inside the paint bucket. However, in actual shaking of the paint bucket, the paint bucket is mostly made of plastic, and when the paint bucket is shaken, the wall of the paint bucket is subjected to the extrusion force of the clamping structure, and the extrusion force changes with the shaking speed and the overall weight of the paint bucket. When the extrusion force is too large, the wall of the paint bucket will be extruded and depressed, and even cracks will appear, resulting in paint leakage. Based on this, a paint mixing device is designed to detect the extrusion force on the wall of the paint bucket and buffer the extrusion force when it is too large, effectively reducing the risk of damage to the wall of the paint bucket caused by extrusion when the paint bucket is shaken. SUMMARY

[0004] In order to make up for the deficiencies of the prior art and solve the technical problems raised in the background art.

[0005] The present application is implemented by the following technical scheme: a paint mixing device, comprising:

[0006] A support is used to support the entire mixing device to work stably;

[0007] A support plate is fixedly installed on the top surface of the support and is used for mounting a driving assembly;

[0008] A rotating shaft penetrates through an installation hole formed in the surface of the support plate and has one end connected with the output end of a servo motor for driving;

[0009] A gear ring is fixedly installed on the surface of the rotating shaft and located above the support plate;

[0010] A shaking ring is provided with arc-shaped meshing teeth on the bottom surface and is installed with a limiting structure on the side surface;

[0011] A receiving plate is fixed between two gear rings and maintains a horizontal state;

[0012] A guide hole is formed in the vertical side of the receiving plate;

[0013] An adjusting plate is inserted through the guide hole;

[0014] A support block is installed at one end of the adjusting plate;

[0015] A connecting plate is fixedly connected to the side of the support block and is in a vertical state;

[0016] A guide plate is inserted through the through hole formed in the side of the connecting plate;

[0017] A clamping block is fixed to one end of the guide plate and has an inclined surface opposite to the non-contact surface of the guide plate;

[0018] An air spring is connected to the surface of the connecting plate at one end and is fixed to the non-inclined surface of the clamping block at the other end;

[0019] A connecting hose is inserted into the air outlet formed at the bottom of the air spring at the top end;

[0020] A gas collecting box is fixed to the surface of the connecting plate;

[0021] An air inlet is formed in the top surface of the gas collecting box and is in communication with the bottom end of the connecting hose;

[0022] A guide rod is fixed to the surface of the clamping block at one end and is movably inserted into the gas collecting box at the other end;

[0023] A blocking plate is fixed to one end of the guide rod inside the gas collecting box and initially blocks the air inlet.

[0024] Specifically, during work, the paint bucket is horizontally placed between the two clamping blocks, supported by the clamping blocks, and then the servo motor is started, the servo motor drives the rotating shaft to reciprocating rotate, the fixed gear ring on the surface of the rotating shaft rotates synchronously, engages with the shaking ring to drive the shaking ring to reciprocating rotate in an arc shape, and the shaking ring drives the paint bucket clamped by the clamping block to shake through the connecting plate and the related structure connected to the connecting plate. In the process of reciprocating shaking of the paint bucket, the paint bucket wall is subjected to the extrusion force of the clamping block. Since the clamping block is connected with the connecting plate through the air spring, and the guide plate on one side of the clamping block penetrates through the through hole formed in the side surface of the connecting plate, the direction of the extrusion force of the clamping block is limited. According to the action and reaction principle, the extrusion force of the clamping block on the paint bucket wall is equal to the extrusion force of the paint bucket wall on the clamping block, and the extrusion force received by the clamping block acts on the inside of the air spring. With the compression of the air spring, the clamping block moves towards the connecting plate, driving the guide rod to move synchronously. The other end of the guide rod penetrates into the gas collecting box and is connected with the blocking plate. Therefore, when the air spring is compressed to a certain degree, the connecting plate drives the blocking plate to move through the guide rod to open the air inlet, so that the connecting hose injects the gas in the air spring into the gas collecting box, the air pressure in the air spring is reduced, the spring force is reduced, and the air spring is further contracted, causing the clamping block to move further towards the connecting plate. In this process, the spring force of the air spring is moderate and cannot be increased, so the extrusion force of the clamping block on the paint bucket wall cannot be further increased. That is, in the process of air release of the air spring, the increase of the extrusion force of the clamping block on the paint bucket wall is buffered and inhibited, and the size of the extrusion force of the clamping block on the paint bucket wall is limited, thereby completing the protection of the paint bucket wall and effectively reducing the risk of damage to the paint bucket wall caused by extrusion when the paint bucket is shaken.

[0025] Further, the paint shaking device further comprises:

[0026] Positioning grooves are uniformly formed in the top surface of the adjusting plate.

[0027] A connecting rod is fixed at one end to the surface of the adjusting plate and inserted at the other end into the connecting groove formed in the side surface of the supporting block.

[0028] A buffer spring is fixedly connected at one end to the surface of the adjusting plate and at the other end to the surface of the supporting block.

[0029] Positioning holes are formed in the top surface of the guide hole, and the hole length and width are the same as the groove length and width of the positioning groove.

[0030] A positioning plate is inserted through the positioning hole into the positioning groove.

[0031] Specifically, during work, when the size diameter of the paint bucket changes, the positioning plate is pulled out of the positioning hole, then the position of the adjusting plate in the guide hole is adjusted, so that the distance between the clamping blocks meets the current paint bucket clamping needs, the positioning plate is reinserted into the positioning hole, as the positioning plate goes deeper, the positioning plate will further insert into the positioning groove, and then the connection between the adjusting plate and the supporting plate is fixed, the clamping distance adjustment for different paint bucket diameters is completed, and the applicability of the equipment is improved. In addition, when the paint bucket is placed between the clamping blocks, in order to avoid the supporting plate from being subjected to excessive impact force and damaging the stable connection between the rotating shaft and the supporting plate part, a buffer spring is arranged, when the paint bucket extrudes the clamping block, the supporting block extrudes the buffer spring, the supporting block moves towards the adjusting plate, and the connecting rod goes deep into the connecting groove on the side surface of the supporting block, this process can effectively complete buffering and avoid the supporting plate from being subjected to large impact, and the rotating shaft can avoid excessive instantaneous impact force on the supporting plate part and damage the stability of the connection between the rotating shaft and the supporting plate part through the shaking ring and the gear ring.

[0032] Further, the paint shaking device further comprises:

[0033] An air extraction cavity is arranged in the clamping block, and the cavity surface is parallel to the inclined surface of the clamping block.

[0034] An extending rod is movably inserted through the air extraction cavity and partially extends to the outside of the inclined surface of the clamping block.

[0035] A supporting spring is fixed at one end of the inner wall of the air extraction cavity and at the other end of one end of the extending rod in the air extraction cavity.

[0036] An air extraction plate is arranged in the air extraction cavity and fixed at the side surface of the extending rod.

[0037] An air extraction opening is arranged at one side of the air extraction cavity close to the inclined surface of the clamping block.

[0038] A suction disc is made of elastic plastic and communicates with the air extraction opening.

[0039] Specifically, during work, when the paint bucket is placed between the clamping blocks, the wall of the paint bucket extrudes the extending rod, the extending rod is extruded to compress the supporting spring and drive the air extraction plate to move in the air extraction cavity, the suction disc is extruded to adhere to the wall of the paint bucket, and the suction disc is made of elastic plastic and is much smaller than the paint bucket, so that the suction disc is sealed with the wall of the paint bucket, the air extraction cavity absorbs the gas in the suction disc through the air extraction opening as the air extraction plate moves in the air extraction cavity, and the suction disc is completely adsorbed to the wall of the paint bucket, so that the paint bucket is prevented from sliding and the stability of the paint bucket shaking is improved.

[0040] Further, the servo motor controls the output end to reciprocate in an arc shape through a set program.

[0041] Further, the positioning plate top is provided with a cover, and the width of the cover is greater than the width of the positioning hole.

[0042] Further, the connecting groove opened on the side surface of the support block is in interference fit with the connecting rod.

[0061] The above description is made in conjunction with the drawingsFigures 1-10 In one embodiment of the present application, a paint mixing device comprises:

[0062] A support 1 is used to support the entire mixing device to work stably;

[0063] A support plate 2 is fixedly installed on the top surface of the support 1 and is used for mounting the driving assembly;

[0064] A rotating shaft 21 horizontally passes through the mounting hole on the surface of the support plate 2 and has one end connected with the output end of a servo motor for driving; the servo motor controls the output end to reciprocatingly rotate in an arc shape through a set program.

[0065] A tooth ring 22 is fixedly installed on the surface of the rotating shaft 21 and is located above the support plate 2;

[0066] A shaking ring 23 is provided with arc-shaped engagement teeth on the bottom surface and is provided with a limiting structure on the side surface, and the arc-shaped engagement teeth are engaged with the tooth ring 22;

[0067] A receiving plate 3 is fixed between the two tooth rings 22 and is kept in a horizontal state;

[0068] A guide hole 31 is formed on the vertical side surface of the receiving plate 3;

[0069] An adjusting plate 32 passes through the guide hole 31;

[0070] A support block 35 is installed on one end of the adjusting plate 32;

[0071] A connecting plate 4 is fixedly connected to the side surface of the support block 35 and is kept in a vertical state;

[0072] A guide plate 41 passes through the through hole formed on the side surface of the connecting plate 4;

[0073] A clamping block 42 is fixed on one end of the guide plate 41 and has an inclined surface on the non-contact surface of the guide plate 41;

[0074] An air spring 5 is connected to the surface of the connecting plate 4 at one end and is fixed to the non-inclined surface of the clamping block 42 at the other end;

[0075] A connecting hose 51 is inserted into the air leakage hole formed on the bottom surface of the air spring 5 at the top end;

[0076] A gas collecting box 52 is fixed to the surface of the connecting plate 4;

[0077] An air inlet 53 is formed on the top surface of the gas collecting box 52 and is in communication with the bottom end of the connecting hose 51;

[0078] A guide rod 54 is fixed to the surface of the clamping block 42 at one end and movably passes through the gas collecting box 52 at the other end;

[0079] A blocking plate 55 is fixed to one end of the guide rod 54 inside the gas collecting box 52, and initially blocks the air inlet 53.

[0080] Specifically, in operation, the paint bucket is placed horizontally between the two clamping blocks 42, supported by the clamping blocks 42, and then the servo motor is started, which drives the rotating shaft 21 to rotate back and forth, the tooth ring 22 fixed on the surface of the rotating shaft 21 rotates synchronously, engages with the wobble ring 23 to drive the wobble ring 23 to rotate back and forth in an arc shape, and the wobble ring 23 drives the paint bucket clamped by the clamping block 42 to shake through the receiving plate 3 and the related structure connected to the receiving plate 3. In the process of the paint bucket shaking back and forth, the paint bucket wall is subjected to the extrusion force of the clamping block 42. Since the clamping block 42 is connected to the connecting plate 4 through the air spring 5, and the guide plate 41 on one side of the clamping block 42 passes through the through hole formed on the side surface of the connecting plate 4, the direction of the extrusion force of the clamping block 42 is limited, and the principle of action and reaction is combined. The extrusion force of the clamping block 42 on the paint bucket wall is equal to the extrusion force of the paint bucket wall on the clamping block 42, and the extrusion force received by the clamping block 42 acts on the inside of the air spring 5. As the air spring 5 is compressed, the clamping block 42 moves towards the connecting plate 4, driving the guide rod 54 to move synchronously. The other end of the guide rod 54 penetrates into the inside of the gas collecting box 52 and is connected with the blocking plate 55. Therefore, when the air spring 5 is compressed to a certain extent, the connecting plate 4 drives the blocking plate 55 to move through the guide rod 54 to open part of the air inlet 53, so that the connecting hose 51 injects the gas in the air spring 5 into the gas collecting box 52, the air pressure in the air spring 5 is reduced, the spring force of the air spring 5 is reduced, and the air spring 5 is further contracted, causing the clamping block 42 to move further towards the connecting plate 4. In this process, the spring force of the air spring 5 cannot be increased, so the extrusion force of the clamping block 42 on the paint bucket wall cannot be further increased. That is, in the process of deflating the air spring 5, the increase of the extrusion force of the clamping block 42 on the paint bucket wall is buffered and inhibited, the size of the extrusion force of the clamping block 42 on the paint bucket wall is limited, and the protection of the paint bucket wall is completed, effectively reducing the risk of damage to the paint bucket wall caused by extrusion when the paint bucket is shaken.

[0081] Further, the paint shaking device further comprises:

[0082] Positioning grooves 33 are uniformly formed on the top surface of the adjusting plate 32;

[0083] A connecting rod 34 is fixed at one end to the surface of the adjusting plate 32 and inserted at the other end into the connecting groove formed on the side surface of the support block 35;

[0084] A buffer spring 36 is fixedly connected at one end to the surface of the adjusting plate 32 and at the other end to the surface of the support block 35;

[0085] Positioning holes 37 are formed on the top surface of the guide hole 31, and the hole length and width are the same as the groove length and width of the positioning groove 33.

[0086] The positioning plate 38 is inserted into the positioning groove 33 through the positioning hole 37.

[0087] Specifically, in operation, when the size of the paint bucket changes, the positioning plate 38 is pulled out of the positioning hole 37, then the position of the adjusting plate 32 in the guide hole 31 is adjusted so that the distance between the clamping blocks 42 meets the current paint bucket clamping requirement, and then the positioning plate 38 is reinserted into the positioning hole 37. As the positioning plate 38 is inserted deeper, the positioning plate 38 is further inserted into the positioning groove 33, thereby fixing the connection between the adjusting plate 32 and the supporting plate 3, completing the clamping distance adjustment for different paint bucket diameters and improving the applicability of the equipment. In addition, when the paint bucket is placed between the clamping blocks 42, in order to avoid the supporting plate 3 being subjected to excessive impact force and damaging the stable connection between the rotating shaft 21 and the supporting plate 2, a buffer spring 36 is arranged. When the paint bucket presses the clamping blocks 42, the supporting block 35 presses the buffer spring 36, and the supporting block 35 moves towards the adjusting plate 32 until the connecting rod 34 is inserted into the connecting groove on the side surface of the supporting block 35. This process can effectively complete the buffering and avoid the supporting plate 3 being subjected to a large impact. The rotating shaft 21 can cause the supporting plate 2 to be subjected to excessive instantaneous impact force and damage the stability of the connection between the rotating shaft 21 and the supporting plate 2 through the shaking ring 23 and the gear ring 22.

[0088] Further, the paint shaking device further comprises:

[0089] The air extraction cavity 6 is arranged in the clamping block 42, and the cavity surface is parallel to the inclined surface of the clamping block 42.

[0090] The extending rod 61 is movably inserted through the air extraction cavity 6 and partially extends to the outside of the inclined surface of the clamping block 42.

[0091] The supporting spring 62 is fixed at one end to the inner wall of the air extraction cavity 6 and at the other end to one end of the extending rod 61 inside the air extraction cavity 6.

[0092] The air extraction plate 63 is arranged inside the air extraction cavity 6 and fixed to the side surface of the extending rod 61.

[0093] The air extraction port 64 is arranged on the side of the air extraction cavity 6 close to the inclined surface of the clamping block 42.

[0094] The suction cup 65 is made of elastic plastic and communicates with the air extraction port 64.

[0095] Specifically, when the paint bucket is placed between the clamping blocks 42 during work, the paint bucket wall will extrude the extension rod 61, the extension rod 61 is extruded to compress the supporting spring 62 and drive the suction plate 63 to move inside the suction cavity 6, since the suction disc 65 is extruded to adhere to the paint bucket wall, and the suction disc 65 is made of elastic plastic and the size is much smaller than the paint bucket, so the suction disc 65 is sealed with the paint bucket wall, with the suction plate 63 moving inside the suction cavity 6, the suction cavity 6 absorbs the gas inside the suction disc 65 through the suction port 64, so the suction disc 65 is completely adsorbed to the paint bucket wall, when the paint bucket shakes, the paint bucket is prevented from sliding, and the stability of the paint bucket shaking is improved.

[0096] Further, the positioning plate 38 is provided with a sealing cover at the top, and the width of the sealing cover is greater than the width of the positioning hole 37. Specifically, the positioning plate 38 inserted into the positioning groove 33 is convenient to draw out.

[0097] Further, the connecting groove on the side surface of the supporting block 35 is in interference fit with the connecting rod 34. Specifically, the loosening of the connecting between the adjusting plate 32 and the supporting block 35 is avoided.

[0098] Further, the sealing plate 55 is rectangular, which completely seals the air inlet 53 at the beginning and slides against the inner top wall of the gas collecting box 52 during movement. Specifically, the air inlet 53 is prevented from leaking gas.

[0099] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
