Description

Technical Field

[0001] The invention belongs to the technical field of painting tools, and in particular relates to a painting pigment extruding device. Background Art

[0002] Paints are a type of coloring material specifically used for painting creation. They are usually made of pigments, color extenders, fillers and other ingredients that have been finely processed. Compared with industrial pigments used in other fields, paints have higher requirements for color, texture, light resistance and other aspects to meet the needs of painting creation; in the painting process, the use and storage of pigments have always been a concern for painting enthusiasts. The traditional way of using paint tubes is usually to squeeze the paint tubes directly by hand and squeeze the paint onto the palette. This method is inconvenient to operate, the squeezing force is difficult to control, and it is easy to cause paint waste. In addition, the paint tubes are also easily squeezed and deformed during use and carrying, affecting the normal use of the pigment.

[0003] In order to solve the above problems, some tools for assisting in squeezing paint tubes have appeared on the market, such as squeezers and pressing plates. However, most of these tools have simple structures and single functions, and cannot effectively protect the paint tubes. They are also less stable during use and are prone to tipping over. At the same time, these tools usually need to be carried separately, which is inconvenient for storage and use. In addition, since painting pigments are sensitive to environmental factors such as air and light, they are prone to deterioration. Therefore, when not in use, the paint tubes need to be effectively protected to avoid dust, pollution and accidental damage, etc., to extend the service life of the paint tubes. However, most of the existing squeezing tools lack the protection function for the paint tubes, which is not conducive to the long-term preservation of the pigments. Summary of the invention

DETAILED DESCRIPTION

[0030] The present invention is further described below in conjunction with the accompanying drawings and embodiments. Example

[0031] This embodiment provides a painting pigment extrusion device, such as Figure 1-9 As shown, it includes a linkage support cover and a center frame 2 installed in the linkage support cover for placing the paint tube 1. The center frame is composed of four columns 21 and a top plate 22. The four columns are vertically fixed at the bottom of the four corners of the top plate. A placement unit and a control unit are provided in the center frame 2. The placement unit includes an extrusion mechanism and a sealing mechanism. The extrusion mechanism includes an extrusion assembly, a platform plate 32, and a tube neck restraint assembly 33. The platform plate 32 is fixedly installed in the center frame 2, and a notch 321 is vertically provided in the middle of the platform plate 32. The mouth of the paint tube passes through the notch and extends downward from the platform plate, and the sealing assembly is installed; the tube neck restraint assembly is matched and installed on the platform plate and is used to clamp the neck of the paint tube above the platform plate with the control unit. Specifically: The tube neck restraint assembly includes a rotating shaft 331, a V-shaped clamp block 332, a locking block 333, and a transverse driving member. The rotating shaft 331 is vertically installed on the platform plate in the middle of the front side of the slot, and the locking block 333 is installed in the middle of the platform plate 32 on the rear side of the slot along the transverse sliding. The locking block 333 is connected to the transverse driving assembly by transmission, and the locking block can be driven to move laterally along the platform plate through the transverse driving assembly; a locking groove 3331 is provided at one end of the locking block 333 facing the slot, and the locking groove 3331 has a large outer opening and a small inner opening, and the left and right inner groove walls of the locking groove are inclined, and the rotating shaft 331 and the locking block are symmetrical Two V-shaped clamps 332 are provided, the head ends of the two V-shaped clamps are rotatably mounted on the rotating shaft, the tail ends of the two V-shaped clamps are matched and inserted into the lock groove of the locking block, and a torsion spring is matched and installed on the rotating shaft. Under a natural state, the torsion spring will drive the two V-shaped clamps to rotate outward in opposite directions around the rotating shaft, so that the tail ends of the two V-shaped clamps will respectively contact the left and right groove walls of the locking groove. Therefore, when the locking block is driven forward by the transverse driving member, the tail ends of the two V-shaped clamps will approach each other under the action of the left and right inclined inner groove walls of the locking groove, so that the neck of the paint tube is clamped by the two V-shaped clamps.

[0032] There are many types of transverse drive components. In this embodiment, the transverse drive component includes a screw rod 334, a hand wheel 335 and a rectangular block 336. Figure 4 As shown, a driving groove 322 is horizontally provided on the upper edge of the platform plate on the rear side of the groove, and the screw is installed in the driving groove along the horizontal rotation, and the tail end of the screw extends backward out of the platform plate and is mounted with a handwheel. A gap matching the screw is arranged in the rectangular block, and is mounted on the screw in the driving groove, and the left and right end surfaces of the rectangular block are respectively in contact with the left and right inner groove walls of the driving groove, and the locking block is fixedly connected to the rectangular block. When the screw is driven to rotate by the handwheel, the screw will drive the rectangular block to drive the locking block to slide back and forth along the driving groove.

[0033] The sealing mechanism 4 includes a bottom plate 41 which is vertically slidably mounted in the center frame below the platform plate, a sealing assembly 42 is matched and mounted on the bottom plate 41, the top end of the sealing assembly 42 is connected to the mouth of the pigment tube 1 below the platform plate 32, a discharge groove 411 is arranged in the middle of the bottom plate 41 in the horizontal direction, the discharge channel of the sealing assembly is connected to the guide groove, an elastic member 43 is arranged between the bottom plate and the platform plate, and the elastic member will push the bottom away from the platform plate in a natural state to control the closing of the sealing assembly; specifically: There are many ways to install the bottom plate vertically in the center frame, for example: a boss is provided on the inner side of the four columns 21 of the center frame below the platform plate, and a lower guide rod 23 is vertically installed on each of the four bosses. The top end of the lower guide rod is vertically connected to the bottom surface of the platform plate. The four top corners of the bottom plate 41 are provided with sliding holes and are respectively mounted on the four lower guide rods 23. The elastic member 43 includes four top springs respectively mounted on the corresponding guide rods. The top spring is located between the bottom plate and the platform plate. In a natural state, the top spring will push the bottom plate to slide downward along the guide rod to the extreme position, and contact with the upper end surface of the boss away from the platform plate, thereby controlling the closing of the sealing assembly.

[0034] The nozzle sealing assembly 42 includes a nozzle sealing cap 421 and a nozzle sealing tube 422. The top of the nozzle sealing cap 421 matches the nozzle of the pigment tube 1. The bottom of the nozzle sealing cap 421 is upwardly provided with a through hole connected to the inner channel of the nozzle of the pigment tube. The diameter of the through hole is the same as the diameter of the inner channel of the nozzle of the pigment tube. The top of the sealing tube 422 is a blocking end, and is inserted into the pigment tube through the through hole. A plurality of feed holes 4211 connected to the internal channel of the sealing tube are evenly arranged along the circumferential direction on the outer ring surface of the top of the sealing tube. The bottom end of the sealing tube is vertically fixed to the bottom plate, and a shallow groove is provided on the bottom plate inside the sealing tube, which is connected to the discharge groove 411. When the tube wall of the pigment tube is squeezed, the pigment inside the pigment tube will enter the pigment tube through the feed hole at the top of the sealing tube and flow out through the discharge groove; when the bottom plate is lifted or lowered, the sealing tube will be driven to rise and fall synchronously along the through hole wall of the sealing cap, and when the bottom plate moves to the extreme position under the action of the elastic member, the top of the sealing tube moves down to the through hole of the sealing cap, and the feed port on the sealing tube is blocked through the hole wall of the through hole.

[0035] The extrusion assembly is installed in the center frame above the platform plate along the vertical sliding, and is connected to the control unit; the flat head of the pigment tube is inserted into the extrusion mechanism from bottom to top, and the control unit controls the extrusion mechanism to move downward to squeeze the outer wall of the dye tube, so that the pigment in the pigment tube is discharged from the pigment tube nozzle, specifically: The extrusion assembly includes an extrusion discharge assembly 6 and a driving assembly 5. The extrusion discharge assembly 6 is vertically slidably installed in the center frame above the platform plate and is connected to the driving assembly in a transmission manner. The flat head of the pigment tube is inserted into the extrusion discharge assembly from bottom to top. The control unit can drive the extrusion discharge assembly to move up and down in the center frame through the driving assembly. The extrusion discharge assembly will squeeze the outer wall of the dye tube during the downward movement, so that the pigment in the pigment tube is discharged from the nozzle of the pigment tube.

[0036] The extrusion discharge component 6 includes an inner frame 61 which is vertically slidably installed in the center frame. Two pressure rollers 62 are longitudinally spaced inside the inner frame 61. The pressure rollers 62 are rotatably installed in the inner frame. The flat head of the paint tube is inserted between the two pressure rollers from bottom to top, and the fixed axis of any one of the two pressure rollers is transmission-connected to the extrusion drive component. The control unit can drive the corresponding pressure roller to move the inner frame up and down along the outer wall of the paint tube through the drive component. In the process of the two pressure rollers moving downward, the pressure roller will squeeze the tube wall of the paint tube, so that the paint in the paint tube is discharged from the mouth of the paint tube.

[0037] The driving assembly 5 includes a driving motor 51 fixedly installed on the rear end face of the inner frame 61 and connected to the control unit. The driving motor 51 is connected to the fixed shaft of the left pressure roller. The control unit can drive the pressure roller connected to the driving motor to rotate through the driving motor. A lifting rack 52 is vertically arranged between the two pressure rollers on the front side of the driving frame. The upper and lower ends of the lifting rack are respectively fixedly connected to the top plate and the platform plate of the center frame; the fixed shaft of the left pressure roller extends forward out of the inner frame and is matched with a gear 53, which is meshed with the lifting rack; when the driving motor drives the left pressure roller to roll downward along the outer wall of the paint tube, the gear will rotate synchronously and move downward along the rack, thereby driving the inner frame to move downward.

[0038] There are many ways to install the inner frame along the vertical sliding path on the center frame. For example, an upper guide rod is vertically fixed at the four top corners of the upper end surface of the platform plate, and the top end of the upper guide rod is vertically fixed to the bottom surface of the center frame top plate. The inner frame is vertically slidably mounted on the four upper guide rods.

[0039] The linkage support cover includes a front cover 7, a rear cover 8, a plug-in assembly and a buckle assembly. The front cover matches the plug-in cover on the center frame from front to back, and the bottom of the front cover is hinged to the center frame. The rear cover is arranged at the rear side of the center frame and is hinged to the bottom of the center frame. The front cover in the erected state is movably connected with the rear cover in the erected state through the buckle assembly to form a complete cover body. Specifically: The fastening assembly includes a fixed shaft a921, a fixed shaft b922 and a rotating rod 923. The fixed shaft a921 and the fixed shaft b922 are respectively fixed on the left end surfaces of the front cover and the rear cover. One end of the rotating rod is rotatably installed and a U-shaped fastener 924 is fixed on the other end. When the front cover and the rear cover are both kept in an upright state, the fixed shaft b is within the trajectory of the U-shaped fastener rotating around the fixed shaft a; therefore, when not in use, the front cover and the rear cover can be combined and connected together to form a complete cover body by rotating the rotating rod to install the U-shaped fastener mouth on the fixed shaft b on the rear cover, and the center frame cover is protected inside the cover body to protect the dye tube.

[0040] like Figure 5As shown, a notch 71 is provided at the bottom of the front panel of the front cover, which is used to avoid the column of the center frame when flipping down, so that the front panel of the front cover 7 can extend into the center frame. When the front cover and the rear cover flip and tilt downward in opposite directions around the corresponding hinged ends, the rear cover can be connected with the front cover through the plug-in assembly to form the support leg of the center frame 2. Since the front cover 7 and the rear cover 8 are both tilted downward, their span is large, thereby being able to improve the stability of the support frame and prevent it from tipping over. Specifically: like Figure 8-9 As shown, the plug-in assembly includes a vertical rod 911, one end of the vertical rod is vertically connected to a long rotating shaft 912, and the other end of the vertical rod is vertically connected to a short plug rod 913. The length of the long rotating shaft is greater than the length of the short plug rod. Two shaft holes 81 matching the plug-in assembly and the short plug rod are vertically spaced apart on the right end surface of the rear cover. The long rotating shaft and the short plug rod are respectively matched and inserted into the corresponding shaft holes, and the long rotating shaft is matched and inserted into the shaft hole near the hinge of the rear cover and the frame. The end of the long rotating shaft away from the vertical rod is fixedly connected to a limiting plate 914, and a compression top spring is matched on the long rotating shaft between the limiting plate and the inner wall of the right end of the rear cover. 915. The compression spring will push the long rotating shaft inward in a natural state to make the vertical rod and the right end face of the rear cover come into contact with each other. The right end face of the front cover is provided with a fixed socket 72 matching the short plug rod. When the front cover and the rear cover are flipped and tilted downward in opposite directions around the corresponding hinged ends, the short plug rod is pulled out of the shaft hole by pulling the vertical rod outward, and the short plug rod is inserted into the fixed socket on the right end face of the front cover. The front cover and the rear cover are connected together by the long rotating shaft and the short plug rod at both ends of the vertical rod. When the tree trunk is falling, the front cover and the rear cover lose their rotation function at the same time, thereby providing stable support for the center frame.

[0041] A driving plate 73 is vertically installed at the bottom of the inner wall on the front side of the front cover. When the hinged end of the front cover is flipped downward, the driving plate will push the bottom plate upward to drive the sealing assembly to open. Therefore, when in use, the painter only needs to control the extrusion discharge assembly to squeeze the dye tube into the discharge trough according to the remaining amount of pigment in the discharge trough through the control unit, and then use the brush to dip the pigment for painting. The control unit includes a controller, a control panel and a power supply. The power supply and the controller are both installed on the rear end face of the center frame. The driving assembly is connected to the power supply through the controller. The control panel is installed in the rear cover and connected to the controller. When the rear cover is flipped upward around the hinged end to the erected state, the power supply and the controller installed on the rear end face of the center frame are both covered inside the rear cover. Example

[0042] The difference between Example 2 and Example 1 is that Fig.10As shown, a locking rack 54 is matched with the side of the gear 53 away from the lifting rack 52. The tooth surface of the locking rack teeth is an inclined surface. The locking rack is installed in the center frame between the top plate and the platform plate along the longitudinal sliding. A top spring a is matched and installed in the center frame away from the gear 53 side. The top spring will drive the locking rack to slide toward the gear 53 side in a natural state, so that the teeth of the locking rack are engaged with the gear 53, thereby cooperating with the lifting rack 52 to lock the gear 53 and constrain the height of the driving frame. When the gear 53 is driven to rotate, the teeth of the gear 53 will push the locking rack along the tooth surface of the locking rack teeth to move the compression top spring a, so that the locking rack slides longitudinally away from the gear 53. Example

[0043] The difference between Example 3 and Example 2 is that a discharge trough is arranged to penetrate the bottom plate outwardly, and a guide groove matching the discharge trough is vertically arranged in the middle of the inner wall on the front side of the front cover. When the hinged end of the front cover is flipped downward, the bottom of the front end of the front cover will enter the center frame and push the top bottom plate upward to drive the sealing assembly to open. When the two pressure rollers of the extrusion and discharge mechanism are controlled by the control unit to move downward to squeeze the dye tube, the pigment in the pigment tube will be discharged through the opened sealing assembly, and the discharged pigment will fall into the guide groove through the discharge trough for dipping. Example

[0044] The difference between Example 4 and Example 3 is that Fig.11 As shown, a plurality of groups of placement units are evenly spaced along the longitudinal direction of the center frame, and a plurality of guide grooves 78 are evenly spaced along the longitudinal direction of the upper inner wall of the front side of the front cover, the guide grooves correspond to the placement units one by one, and the positions of the guide grooves correspond to the positions of the discharge grooves in each placement unit, respectively. A primary retention groove 74 is provided at one end of each guide groove near the top of the front cover, a secondary retention groove 75 is provided on the front inner wall of the front cover near the top of the front cover between every two adjacent primary retention grooves, a tertiary retention groove 76 is provided on the front inner wall of the front cover near the top of the front cover between every two adjacent secondary retention grooves, and a tertiary retention groove 76 is provided between the secondary retention groove and the adjacent two primary retention grooves and between the tertiary retention grooves. Shallow grooves 77 are provided on the inner wall of the front cover between the retention groove and the two adjacent secondary retention grooves. The two ends of the shallow groove connect the corresponding retention grooves of the upper and lower levels to form a discharge network. When the rear cover is connected to the front cover through a plug-in assembly to form the support legs of the center frame, the bottoms of the primary retention groove, the secondary retention groove and the tertiary retention groove are in a horizontal state. Therefore, when the pigment falls into the guide groove, as the pigment is discharged, the pigment discharged from different pigment tubes will stand in the corresponding primary retention groove and gather. As the pigment in the primary retention groove continues to increase, the pigments in the two adjacent primary retention grooves will automatically flow into the secondary retention groove through the shallow groove and mix together, thereby automatically matching colors.

[0045] It should be understood that the above specific embodiments of the present invention are only used to illustrate or explain the principles of the present invention, and do not constitute a limitation of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention should be included in the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or the equivalent forms of such scope and boundaries.
