Description

Technical Field

[0001] The invention relates to the technical field of intelligent freezers, and in particular to an intelligent freezer for automatically taking and placing shrimp products. Background Art

[0002] The smart freezer is equipped with a high-precision temperature control system that can maintain a temperature range between -18°C and -25°C. Shrimp products are sensitive to temperature. Too high a temperature can easily lead to thawing and deterioration, while too low a temperature will affect the taste and quality of the shrimp meat. Therefore, the smart freezer can ensure that the temperature is always kept within the ideal range through real-time temperature monitoring. Shrimp products need to maintain appropriate humidity during storage. Too low humidity will cause the meat to dry out and affect the taste. Smart freezers are often equipped with a humidity control system that automatically adjusts the humidity according to the storage requirements of the shrimp to ensure its optimal preservation state. The smart freezer for storing shrimp products in the prior art is not easy to operate when a large number of shrimps need to be put in and taken out. Summary of the invention

[0003] In view of the above technical problems, the technical solution adopted by the present invention is: an intelligent freezer for shrimp products with automatic pick-up and placement, including a freezer device for freezing shrimp products, the freezer device including a freezer body, the freezer device is provided with two adjustment devices for adjusting the height of each placement layer and a pick-up and placement device for extending the placement layer, the adjustment device includes a clamping plate, the clamping plate is fixedly installed on the side of the freezer body, and the pick-up and placement device includes a lifting frame.

[0004] Furthermore, the freezer device includes a freezer door rotatably mounted on the freezer body, a rear motor and two rear guide rails are fixedly mounted on the freezer body, a rear screw is rotatably mounted on the inner wall of the freezer body, the rear screw is fixedly mounted to the motor shaft of the rear motor, side motors and two side guide rails are fixedly mounted on the inner walls on both sides of the freezer body, a side screw is fixedly mounted on the motor shaft of the side motor, and the side screw is rotatably mounted to the inner wall of the freezer body.

[0005] The rotation of the rear motor drives the rear screw to rotate, and the rotation of the side motor determines the rotation of the side screw.

[0006] Furthermore, the adjustment device includes a plurality of clamping plates arranged on the clamping plate, the distance between each clamping plate is equal, and three slide-out mechanisms are arranged on the side guide rail.

[0007] Furthermore, the sliding mechanism includes a lifting slide, on which an internal thread ring is rotatably installed, an internal thread is arranged inside the internal thread ring, the internal thread of the internal thread ring cooperates with the external thread of the side screw rod, and two horizontal slides and two vertical slides are fixedly installed on the lifting slide, and the vertical slides are slidably installed with the side guide rails.

[0008] Furthermore, an electromagnet is fixedly installed in the lifting slide, a docking frame is slidably installed on the lifting slide, a docking friction plate is fixedly installed in the docking frame, a magnetic column and a clamping column are fixedly installed on the docking frame, a compression spring is arranged between the docking frame and the lifting slide, and the magnetic column is a magnetic material.

[0009] Furthermore, when the electromagnet is not energized, the card column is located between the two card plates. When the electromagnet is energized, the magnetic suction column is adsorbed, and the card column is separated from between the two card plates.

[0010] When the height of one of the three slide-out mechanisms needs to be adjusted, the electromagnet of the slide-out mechanism that needs to be adjusted is energized, and the electromagnets of the other two slide-out mechanisms are not energized. The clamping column is located between the clamping plates, and the electromagnet absorbs the magnetic suction column, causing the docking frame and the docking friction plate to slide toward the inner thread circle, the docking friction plate fits with the inner thread circle, the compression spring is compressed, and the clamping column leaves between the two clamping plates. At this time, the side screw rotates. At this time, the slide-out mechanism in which the docking friction plate fits with the inner thread circle drives the lifting slide and the vertical slide block along the side guide through the thread transmission with the inner thread circle. The rail is lifted and lowered, and the other two butt friction plates and the inner thread ring are not fitted with the slide-out mechanism. The inner thread ring rotates together with the side screw rod, and the clamping column is blocked by the clamping plate and cannot be lifted or lowered. The inner thread ring and the lifting slide rotate relatively, and the inner thread ring rotates together with the side screw rod. At this time, the lifting slide will not rise or fall, thereby realizing the height adjustment of one slide-out mechanism, while the positions of the other two slide-out mechanisms remain unchanged. When the height adjustment of the slide-out mechanism is completed, the electromagnet loses power, and the compression spring rebounds, so that the butt friction plate and the inner thread ring are separated, and the clamping column is re-inserted between the two clamping plates.

[0011] Furthermore, the pick-and-place device comprises a placement plate slidably mounted on the transverse slider, and a docking groove plate is fixedly mounted behind the placement plate.

[0012] Furthermore, a screw motor is fixedly installed on the lifting frame, and the lifting frame and the rear screw form a threaded transmission. Two lifting sliders are fixedly installed on the lifting frame, and the lifting sliders are slidably installed with the rear guide rails. A horizontal screw is rotatably installed in the lifting frame, and the horizontal screw is fixedly installed with the motor shaft of the screw motor.

[0013] Furthermore, a distal slider and a proximal slider are slidably installed in the lifting frame, and the distal slider and the proximal slider are respectively provided with internal threads with opposite thread directions. A short rotating rod is rotatably installed on the distal slider, and a long rotating rod is rotatably installed on the proximal slider. The long rotating rod and the short rotating rod are rotatably installed, and a docking column is rotatably installed on the end of the long rotating rod.

[0014] When the distal slider and the proximal slider are at the outermost position, the lifting and lowering of the long rotating rod and the short rotating rod will not be blocked by the docking slot plate. At this time, the lifting and lowering of the lifting slide will drive the placement plate to lift and lower together, thereby adjusting the height of the placement plate. When the placement plate needs to be pushed out, the freezer door is opened first, and the rear screw rod rotates to drive the lifting and lowering frame to lift and lower, thereby driving the long rotating rod and the short rotating rod to lift and lower. When the docking column and the placement plate and the docking slot plate that need to be extended reach the same height, the rear screw rod stops rotating. At this time, the screw rod motor rotates to drive the horizontal screw rod to rotate, thereby driving the distal slider and the proximal slider to move inward at the same time, thereby driving the short rotating rod and the long rotating rod to rotate. The long rotating rod rotates to drive the docking column to extend, and after the docking column and the placement plate are fitted The docking column pushes the placement plate to slide outward along the horizontal slider, and the docking column enters the docking groove plate. The docking column rolls along the docking groove plate. When the placement plate extends out of the freezer body, it is convenient to place the shrimp products on the placement plate. Then the placement plate needs to be retracted into the freezer body. When the shrimp needs to be put in, similarly, when the proximal slider and the distal slider slide outward, the short rotating rod and the long rotating rod are driven to rotate, and the placement plate and the docking groove plate are pulled back into the freezer body through the docking column. Then, when the proximal slider and the distal slider move to the outermost side, the docking column is disengaged from the docking groove plate, and the long rotating rod and the short rotating rod leave the top of the docking groove plate. At this time, the placement plate can be driven by the lifting slide to be lifted and lowered, and then the freezer door is closed.

[0015] Compared with the prior art, the present invention has the following advantages: (1) the refrigerator provided by the present invention is provided with three slide-out mechanisms, and the heights of the three slide-out mechanisms can be adjusted automatically and independently. When there is no need to adjust the height of the slide-out mechanism, the slide-out mechanism can be kept in a fixed position by a positioning plate, which is convenient to use and convenient for stacking shrimp products; (2) the pick-and-place device provided by the present invention can be adjusted according to the height of different slide-out mechanisms. During the lifting and lowering process, the pick-and-place device will not be affected by the position of the slide-out mechanism. When the pick-and-place device is lifted and lowered to the position of the slide-out mechanism that needs to be pushed out, the placement tray can be pushed out and pulled back, which is convenient for taking and placing shrimp products; (3) the three slide-out mechanisms provided by the present invention can be independently adjusted in height and pushed out and pulled back, and each slide-out mechanism does not interfere with each other, which is convenient to use.

DETAILED DESCRIPTION

[0028] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0030] like Figure 3 , Figure 4 As shown, the freezer device includes a freezer door 102 rotatably mounted on a freezer body 101, a rear motor 103 and two rear guide rails 105 are fixedly mounted inside the freezer body 101, a rear screw rod 104 is rotatably mounted on the inner wall of the freezer body 101, the rear screw rod 104 is fixedly mounted to the motor shaft of the rear motor 103, a side motor 106 and two side guide rails 108 are fixedly mounted on the inner walls on both sides of the freezer body 101, a side screw rod 107 is fixedly mounted on the motor shaft of the side motor 106, and the side screw rod 107 is rotatably mounted to the inner wall of the freezer body 101.

[0031] The rear motor 103 rotates to drive the rear screw rod 104 to rotate, and the side motor 106 rotates to ensure that the side screw rod 107 rotates.

[0032] like Figure 5-Figure 8 As shown, the adjustment device includes a plurality of clamping plates 212 arranged on the clamping plate 201 , the distances between each clamping plate 212 are equal, and three slide-out mechanisms are arranged on the side guide rail 108 .

[0033] like Figure 5-Figure 8 As shown, the sliding mechanism includes a lifting slide 202, on which an internal thread ring 203 is rotatably installed. An internal thread is arranged inside the internal thread ring 203. The internal thread of the internal thread ring 203 cooperates with the external thread of the side screw rod 107. Two horizontal sliders 204 and two vertical sliders 205 are fixedly installed on the lifting slide 202. The vertical sliders 205 are slidably installed with the side guide rails 108.

[0034] like Figure 5-Figure 8 As shown, an electromagnet 209 is fixedly installed in the lifting slide 202, a docking frame 206 is slidably installed on the lifting slide 202, a docking friction plate 211 is fixedly installed in the docking frame 206, a magnetic column 208 and a clamping column 207 are fixedly installed on the docking frame 206, a compression spring 210 is arranged between the docking frame 206 and the lifting slide 202, and the magnetic column 208 is a magnetic material.

[0035] like Figure 5-Figure 8 As shown, when the electromagnet 209 is not energized, the clamping column 207 is located between the two clamping plates 212 . When the electromagnet 209 is energized, the magnetic suction column 208 is adsorbed, and the clamping column 207 is separated from the two clamping plates 212 .

[0036] When it is necessary to adjust the height of one of the three slide-out mechanisms, the electromagnet 209 of the slide-out mechanism that needs to be adjusted is energized, and the electromagnets 209 of the other two slide-out mechanisms are not energized. The clamping column 207 is located between the clamping plates 212, and the electromagnet 209 adsorbs the magnetic suction column 208, so that the docking frame 206 and the docking friction plate 211 slide toward the internal thread ring 203, and the docking friction plate 211 fits with the internal thread ring 203. The compression spring 210 is compressed, and the clamping column 207 leaves between the two clamping plates 212. At this time, the side screw rod 107 rotates. At this time, the slide-out mechanism in which the docking friction plate 211 fits with the internal thread ring 203 drives the lifting slide 202 and the vertical slide block 205 along the internal thread ring 203 through the thread transmission with the internal thread ring 203. As the side guide rail 108 rises and falls, the other two butt friction plates 211 and the inner thread ring 203 are not fitted into the slide-out mechanism. The inner thread ring 203 rotates together with the side screw rod 107, and the clamping column 207 is blocked by the clamping plate 212 and cannot be lifted or lowered. The inner thread ring 203 and the lifting slide 202 rotate relative to each other, and the inner thread ring 203 rotates together with the side screw rod 107. At this time, the lifting slide 202 will not rise or fall, thereby realizing the height adjustment of one slide-out mechanism, while the positions of the other two slide-out mechanisms remain unchanged. When the height adjustment of the slide-out mechanism is completed, the electromagnet 209 loses power, and the compression spring 210 rebounds, so that the butt friction plate 211 is disengaged from the inner thread ring 203, and the clamping column 207 is re-inserted between the two clamping plates 212.

[0037] like Figure 9-11 As shown, the pick-and-place device includes a placement plate 309 slidably mounted on the horizontal slider 204 , and a docking groove plate 310 is fixedly mounted behind the placement plate 309 .

[0038] like Figure 9-11 As shown, a screw motor 302 is fixedly installed on the lifting frame 301, and the lifting frame 301 and the rear screw 104 form a threaded transmission. Two lifting sliders 311 are fixedly installed on the lifting frame 301. The lifting sliders 311 are slidably installed with the rear guide rail 105. A horizontal screw 303 is rotatably installed in the lifting frame 301, and the horizontal screw 303 is fixedly installed with the motor shaft of the screw motor 302.

[0039] like Figure 9-11 As shown, a distal slider 306 and a proximal slider 307 are slidably installed in the lifting frame 301, and the distal slider 306 and the proximal slider 307 are respectively provided with internal threads with opposite directions. A short rotating rod 304 is rotatably installed on the distal slider 306, and a long rotating rod 305 is rotatably installed on the proximal slider 307. The long rotating rod 305 is rotatably installed with the short rotating rod 304, and a docking column 308 is rotatably installed on the end of the long rotating rod 305.

[0040] When the distal slider 306 and the proximal slider 307 are at the outermost position, the lifting and lowering of the long rotating rod 305 and the short rotating rod 304 will not be blocked by the docking groove plate 310. At this time, the lifting and lowering of the lifting slide 202 will drive the placement plate 309 to lift together, thereby adjusting the height of the placement plate 309. When the placement plate 309 needs to be pushed out, the refrigerator door 102 is first opened, and the rear screw rod 104 rotates to drive the lifting frame 301 to lift, thereby driving the long rotating rod 305 and the short rotating rod 304 to lift. When the docking column 308 reaches the same height as the placement plate 309 and the docking slot plate 310 that need to be extended, the rear screw rod 104 stops rotating, and the screw motor 302 rotates to drive the horizontal screw rod 303 to rotate, thereby driving the distal slider 306 and the proximal slider 307 to move inward at the same time, thereby driving the short rotating rod 304 and the long rotating rod 305 to rotate, and the long rotating rod 305 rotates to drive the docking column 308 to extend, and the docking column 308 is fitted with the placement plate 309, and the docking The post 308 pushes the placement plate 309 to slide outward along the horizontal slider 204, and the docking post 308 enters the docking groove plate 310. The docking post 308 rolls along the docking groove plate 310. When the placement plate 309 extends out of the freezer body 101, it is convenient to place the shrimp products on the placement plate 309. Then, the placement plate 309 needs to be retracted into the freezer body 101. When the shrimp needs to be placed, the proximal slider 307 and the distal slider 306 slide outward in the same way, driving The short rotating rod 304 and the long rotating rod 305 rotate, and the placement plate 309 and the docking groove plate 310 are pulled back into the freezer body 101 through the docking column 308. Then, when the proximal slider 307 and the distal slider 306 move to the outermost side, the docking column 308 disengages from the docking groove plate 310, and the long rotating rod 305 and the short rotating rod 304 leave the top of the docking groove plate 310. At this time, the placement plate 309 can be driven by the lifting slide 202 to be lifted and lowered, and then the freezer door 102 is closed.

[0041] The working principle of the intelligent freezer for shrimp products that can be automatically taken and placed disclosed by the present invention is as follows: the rear motor 103 rotates to drive the rear screw 104 to rotate, and the side motor 106 rotates to determine the rotation of the side screw 107. When it is necessary to adjust the height of one of the three slide-out mechanisms, the electromagnet 209 of the slide-out mechanism that needs to be adjusted is energized, and the electromagnets 209 of the other two slide-out mechanisms are not energized. The clamping column 207 is located between the clamping plates 212, and the electromagnet 209 adsorbs the magnetic suction column 208, so that the docking frame 206 and the docking friction plate 211 slide toward the inner thread ring 203, and the docking friction plate 211 fits with the inner thread ring 203. The compression spring 210 is compressed, and the clamping column 207 leaves between the two clamping plates 212. At this time, the side screw 107 rotates. At this time, the slide-out mechanism in which the docking friction plate 211 fits with the inner thread ring 203 drives the lifting slide 202 and the vertical slider 205 along the inner thread ring 203 through the thread transmission with the inner thread ring 203. As the side guide rail 108 rises and falls, the other two butt friction plates 211 and the inner thread ring 203 are not fitted into the slide-out mechanism. The inner thread ring 203 rotates together with the side screw rod 107, and the clamping column 207 is blocked by the clamping plate 212 and cannot be lifted or lowered. The inner thread ring 203 and the lifting slide 202 rotate relative to each other, and the inner thread ring 203 rotates together with the side screw rod 107. At this time, the lifting slide 202 will not rise or fall, thereby realizing the height adjustment of one slide-out mechanism, while the positions of the other two slide-out mechanisms remain unchanged. When the height adjustment of the slide-out mechanism is completed, the electromagnet 209 loses power, and the compression spring 210 rebounds, so that the butt friction plate 211 is disengaged from the inner thread ring 203, and the clamping column 207 is re-inserted between the two clamping plates 212.When the distal slider 306 and the proximal slider 307 are at the outermost position, the lifting and lowering of the long rotating rod 305 and the short rotating rod 304 will not be blocked by the docking groove plate 310. At this time, the lifting and lowering of the lifting slide 202 will drive the placement plate 309 to lift together, thereby adjusting the height of the placement plate 309. When the placement plate 309 needs to be pushed out, the refrigerator door 102 is first opened, and the rear screw rod 104 rotates to drive the lifting frame 301 to lift, thereby driving the long rotating rod 305 and the short rotating rod 304 to lift. When the docking column 308 reaches the same height as the placement plate 309 and the docking slot plate 310 that need to be extended, the rear screw rod 104 stops rotating, and the screw motor 302 rotates to drive the horizontal screw rod 303 to rotate, thereby driving the distal slider 306 and the proximal slider 307 to move inward at the same time, thereby driving the short rotating rod 304 and the long rotating rod 305 to rotate, and the long rotating rod 305 rotates to drive the docking column 308 to extend, and the docking column 308 is fitted with the placement plate 309, and the docking The post 308 pushes the placement plate 309 to slide outward along the horizontal slider 204, and the docking post 308 enters the docking groove plate 310. The docking post 308 rolls along the docking groove plate 310. When the placement plate 309 extends out of the freezer body 101, it is convenient to place the shrimp products on the placement plate 309. Then, the placement plate 309 needs to be retracted into the freezer body 101. When the shrimp needs to be placed, the proximal slider 307 and the distal slider 306 slide outward in the same way, driving The short rotating rod 304 and the long rotating rod 305 rotate, and the placement plate 309 and the docking groove plate 310 are pulled back into the freezer body 101 through the docking column 308. Then, when the proximal slider 307 and the distal slider 306 move to the outermost side, the docking column 308 disengages from the docking groove plate 310, and the long rotating rod 305 and the short rotating rod 304 leave the top of the docking groove plate 310. At this time, the placement plate 309 can be driven by the lifting slide 202 to be lifted and lowered, and then the freezer door 102 is closed.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope of the present invention, which should be covered by the protection scope of the present invention.
