Description

Technical Field

[0001] This utility model relates to the field of pigment extraction technology, specifically a blueberry pressing device for extracting natural pigments. Background Technology

[0002] Blueberries, an important economic crop, are rich in natural pigments, vitamins, and antioxidants, and are widely used in the food, pharmaceutical, and cosmetic industries. In the deep processing of blueberries, pressing to extract pigments is the core process, and the structural design of the filter plates in the pressing device directly affects extraction efficiency and production costs.

[0003] Current blueberry pressing equipment generally uses filter plates to separate juice from pomace. These filter plates are typically connected to the main body of the equipment using traditional fasteners such as bolts and screws. However, in practical applications, filter plates are prone to clogging or wear after long-term use, requiring frequent replacement. Traditional bolt / screw fastening requires disassembling each bolt individually with tools, a cumbersome process. Taking a common four-sided fixed filter plate as an example, a single replacement requires operating 8-12 bolts, taking 15-20 minutes, which seriously affects the continuous production schedule. Utility Model Content

[0004] The purpose of this invention is to provide a blueberry pressing device for extracting natural pigments, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a blueberry pressing device for natural pigment extraction, comprising a crushing box, an inlet at the top of the crushing box, an outlet at the bottom of the crushing box, a fixing frame inserted into the inner wall of the crushing box, a filter plate fixed inside the fixing frame, and a docking assembly provided inside the crushing box.

[0006] The docking components include:

[0007] The long pole is used to stabilize the mounting frame;

[0008] Through holes are used to fit long rods for insertion.

[0009] A cavity is used to stabilize its internal structure.

[0010] Preferably, the long rod is fixed to the inner wall of the crushing box. The surface of the fixing frame has a through hole, and the inside of the long rod has a cavity. A rotating rod is rotatably connected to the inner wall of the cavity, and the rotating rod passes through the long rod. A spiral spring is fixed to the surface of the rotating rod, and the end of the spiral spring away from the rotating rod is fixed to the inner wall of the cavity. A fixing plate is fixed to the surface of the rotating rod, and a movable plate is hinged to the end of the fixing plate away from the rotating rod. A locking plate is hinged to the end of the movable plate away from the fixing plate, and the end of the locking plate away from the movable plate passes through the long rod. The clamping plate is slidably connected to the long rod. The inner wall of the through hole is provided with a groove. A fixing block is fixed to the end of the long rod away from the spiral spring. The docking assembly also includes a protective component. When the connecting cover is rotated, the fixing block and the rotating rod rotate. The fixing plate drives the movable plate to rotate synchronously. The movable plate pulls the clamping plate away from the groove, which releases the limitation on the fixing frame. At this time, the filter plate can be pulled out normally. During installation, the long rod is inserted into the through hole. The clamping plate enters the groove through the fixing plate, the movable plate, the rotating rod, and the spiral spring, which limits the fixing frame and the filter plate, making installation convenient.

[0011] Preferably, the protective component includes a connecting cover, which is disposed on the surface of the fixing block. A connecting plate is fixed to the inner side of the connecting cover. An annular groove is formed on the surface of the fixing block, and a stabilizing groove is formed on the surface of the fixing block. The stabilizing groove communicates with the annular groove. Pushing the connecting cover causes the connecting plate to move into the annular groove. When the connecting cover rotates accidentally, it will not drive the fixing block to rotate synchronously, thus avoiding affecting the stability of the filter plate.

[0012] Preferably, a cylinder is fixed to the surface of the crushing box, the output end of the cylinder passes through the crushing box, and a pressing plate is fixed to the output end of the cylinder to facilitate the pressing of blueberries.

[0013] Preferably, a crushing roller is rotatably connected to the inner wall of the crushing box, a motor is fixed to the surface of the crushing box, the output shaft of the motor passes through the crushing box and is fixed to the surface of the crushing roller, and a box door is installed on the surface of the crushing box to facilitate the crushing of blueberries.

[0014] Preferably, the end of the card plate away from the movable plate is set as an inclined surface, which can drive the card plate to move into the cavity when it is pressed.

[0015] Compared with the prior art, this utility model provides a blueberry pressing device for natural pigment extraction, which has the following beneficial effects:

[0016] This blueberry pressing device for natural pigment extraction, through its docking components, allows for easy replacement and cleaning of the filter plates. Rotating the connecting cover causes the fixed block and rotating rod to rotate, simultaneously flipping the movable plate. The movable plate pulls the retaining plate out of the slot, releasing the restriction on the fixing frame. The filter plates can then be easily removed. During installation, inserting a long rod into the through hole allows the retaining plate to move into the slot via the fixed plate, movable plate, rotating rod, and spiral spring, thus limiting the fixing frame and filter plates for easy installation. A protective mechanism pushes the connecting cover, causing the connecting plate to move into the annular groove. Accidental rotation of the connecting cover prevents the fixed block from rotating simultaneously, thus avoiding impact on the stability of the filter plates. Attached Figure Description

[0023] like Figures 1-5As shown, this utility model provides a technical solution: a blueberry pressing device for natural pigment extraction, including a crushing box 1, a feed inlet 2 at the top of the crushing box 1, a discharge outlet 3 at the bottom of the crushing box 1, a fixing frame 10 inserted into the inner wall of the crushing box 1, a filter plate 11 fixed on the inner side of the fixing frame 10, and a docking assembly 9 provided inside the crushing box 1; the docking assembly 9 includes: a long rod 90, a through hole 91, a cavity 92, a rotating rod 93, a spiral spring 94, a fixing plate 95, a movable plate 96, a clamping plate 97, a clamping groove 98, a fixing block 900, a protective component 99, a connecting cover 990, a connecting plate 991, an annular groove 992, and a stabilizing groove 993.

[0024] A long rod 90 is fixed to the inner wall of the crushing box 1. A through hole 91 is opened on the surface of the fixing frame 10. A cavity 92 is opened inside the long rod 90. A rotating rod 93 is rotatably connected to the inner wall of the cavity 92. The rotating rod 93 passes through the long rod 90. A spiral spring 94 is fixed to the surface of the rotating rod 93. The end of the spiral spring 94 away from the rotating rod 93 is fixed to the inner wall of the cavity 92. A fixing plate 95 is fixed to the surface of the rotating rod 93. A movable plate 96 is hinged to the end of the fixing plate 95 away from the rotating rod 93. A locking plate 97 is hinged to the end of the movable plate 96 away from the fixing plate 95. 7. The end of the rod 90 away from the movable plate 96 passes through the long rod 90, and the clamping plate 97 is slidably connected to the long rod 90. The inner wall of the through hole 91 is provided with a groove 98. The end of the long rod 90 away from the spiral spring 94 is fixed with a fixing block 900. The docking assembly 9 also includes a protective component 99, which includes a connecting cover 990. The connecting cover 990 is disposed on the surface of the fixing block 900. A connecting plate 991 is fixed to the inner side of the connecting cover 990. An annular groove 992 is provided on the surface of the fixing block 900. A stabilizing groove 993 is provided on the surface of the fixing block 900. The stabilizing groove 993 and the annular groove 992 are connected. The grooves 992 are interconnected. The end of the clamping plate 97 away from the movable plate 96 is set as an inclined surface. Pulling the connecting cover 990, the connecting plate 991 moves into the stabilizing groove 993. Rotating the connecting cover 990, the fixing block 900 and the rotating rod 93 rotate. The fixing plate 95 drives the movable plate 96 to rotate synchronously. The movable plate 96 pulls the clamping plate 97 out of the clamping groove 98, thus releasing the limitation on the fixing frame 10. At this time, the filter plate 11 can be pulled out normally. During installation, the long rod 90 is inserted into the through hole 91. The inner wall of the through hole 91 abuts against the inclined surface of the clamping plate 97. The clamping plate 97 moves into the cavity 92. The movable plate 96 drives the fixed plate 95 and the rotating rod 93 to rotate. At this time, the spiral spring 94 is wound up. When the position of the clamping plate 97 is parallel to the clamping groove 98, the spiral spring 94 is released, and it can be reset through the fixed plate 95, the movable plate 96, and the clamping plate 97. At this time, the clamping plate 97 enters the clamping groove 98, which can limit the fixed frame 10 and the filter plate 11 for easy installation. At this time, push the connecting cover 990 so that the connecting plate 991 moves into the annular groove 992. When the connecting cover 990 rotates accidentally, it will not drive the fixed block 900 to rotate synchronously, so as to avoid affecting the stability of the filter plate 11.

[0025] A cylinder 7 is fixed to the surface of the crushing box 1. The output end of the cylinder 7 passes through the crushing box 1, and a pressing plate 8 is fixed to the output end of the cylinder 7. A crushing roller 6 is rotatably connected to the inner wall of the crushing box 1. A motor 5 is fixed to the surface of the crushing box 1. The output shaft of the motor 5 passes through the crushing box 1 and is fixed to the surface of the crushing roller 6. A box door 4 is installed on the surface of the crushing box 1. When the motor 5 is turned on, the crushing roller 6 can be rotated to crush the blueberries. The crushed blueberries fall onto the surface of the filter plate 11. When the cylinder 7 is turned on, the pressing plate 8 can be pressed to squeeze the blueberries.

[0026] When blueberries need to be pressed to extract natural pigments, they are fed into the feed inlet 2, and the motor 5 is turned on, causing the crushing roller 6 to rotate and crush the blueberries. The crushed blueberries fall onto the surface of the filter plate 11. The cylinder 7 is then turned on, causing the extrusion plate 8 to press the blueberries, and the filter plate 11 filters the juice. The pressed juice is discharged through the discharge outlet 3 for easy collection. When the filter plate 11 needs to be replaced or cleaned, the connecting cover 990 is pulled, at which point the connecting plate 991 moves into the stabilizing groove 993. Rotating the connecting cover 990 simultaneously drives the fixing block 900 and the rotating rod 93 to rotate. At this time, the fixing plate 95 drives the movable plate 96 to rotate synchronously. The movable plate 96 pulls the clamping plate 97 out of the clamping groove 98, thus releasing the clamping frame 10. Limiting the position, the filter plate 11 can be pulled out normally. During installation, insert the long rod 90 into the through hole 91. At this time, the inner wall of the through hole 91 abuts against the inclined surface of the clamping plate 97. The clamping plate 97 moves into the cavity 92. The movable plate 96 drives the fixed plate 95 and the rotating rod 93 to rotate. At this time, the spiral spring 94 is wound up. When the position of the clamping plate 97 is parallel to the slot 98, the spiral spring 94 is released, and the fixed plate 95, the movable plate 96, and the clamping plate 97 can be reset. At this time, the clamping plate 97 enters the slot 98, which can limit the fixed frame 10 and the filter plate 11 for easy installation. At this time, push the connecting cover 990 so that the connecting plate 991 moves into the annular groove 992. When the connecting cover 990 rotates accidentally, it will not drive the fixed block 900 to rotate synchronously, so as to avoid affecting the stability of the filter plate 11.
