[0031] According to the present specific embodiment, the two slide plates 108 are fixedly connected to the base plate 102 and are located on one side of the base plate 102. The two guide rods 109 respectively penetrate the two slide plates 108 and are slidably connected to the two slide plates 108. Both ends of each guide rod 109 are fixedly connected to the mobile frame 101. The vertical plate 103 is fixedly connected to the base plate 102 and is located on the upper surface of the base plate 102. The electric slide rail 106 is fixedly connected to the base plate 102 and is located on the upper surface of the base plate 102. The upper surface of the bottom plate 102, the sliding sleeve 107 is slidably connected to the electric slide rail 106, the placement plate 104 is fixedly connected to the sliding sleeve 107 and is located on the upper surface of the sliding sleeve 107, the abutting plate 105 is fixedly connected to the placement plate 104 and is located at one end of the placement plate 104, the two groups of the lifting components are symmetrically arranged on the upper surface of the placement plate 104, the fixing component is arranged on the lower surface of the bottom plate 102, and when in use, the sliding sleeve 107 is used to lift the electric slide rail 106. The bottom plate 102 is then driven upward by the lifting assembly to move the placement plate 104 to fit the bottom surface of the cargo. The sliding sleeve 107 then drives the placement plate 104 to move toward the vertical plate 103. The placement plate 104 drives the abutting plate 105 to move. The abutting plate 105 abuts against the cargo to move until the cargo abuts against the vertical plate 103. The cargo is then clamped and fixed on both sides by the fixing assembly. The mobile rack 101 moves, driving the goods to move horizontally, and drives the bottom plate 102 to move up and down through the two sets of lifting components, thereby driving the goods to move longitudinally, so as to move the goods to the corresponding storage location, and then drives the placement plate 104 to move through the sliding sleeve 107, and the placement plate 104 drives the goods to move into the storage location, and then drives the bottom plate 102 to move downward through the two sets of lifting components, so that the supporting plate 105 moves to the bottom of the goods, and then retracts the placement plate 104, thereby completing the stacking of the goods.

[0032] Among them, the triangular frame 112 is fixedly connected to the base plate 102 and is located on the upper surface of the base plate 102, the winch 110 is fixedly connected to the movable frame 101, one end of the steel wire rope 111 is fixedly connected to the triangular frame 112, and the other end of the steel wire rope 111 is fixedly connected to the output end of the winch 110.

The motor 115 is fixedly connected to one of the mounting plates 113, and the output end of the motor 115 is fixedly connected to the two-way threaded rod 114. When in specific use, the motor 115 is started, and the output end of the motor 115 drives the two-way threaded rod 114 to rotate, so that the two groups of clamping members move relative to each other, thereby clamping and fixing the goods.

[0034] At the same time, the movable plate 116 passes through the base plate 102 and is slidably connected to the base plate 102. One end of the movable plate 116 is threadedly matched with the bidirectional threaded rod 114, and the other end of the movable plate 116 is fixedly connected to the clamping plate 117. When in use, the bidirectional threaded rod 114 rotates to move the movable plate 116, and the movable plate 116 drives the clamping plate 117 to move.

[0035] When using a stacker of the present embodiment, the sliding sleeve 107 slides on the electric slide rail 106 to move the placement plate 104 to the bottom of the goods, and then the winch 110 winds up the wire rope 111 to move the bottom plate 102 upward so that the placement plate 104 fits the bottom surface of the goods, and then the sliding sleeve 107 drives the placement plate 104 to move toward the vertical plate 103, and the placement plate 104 drives the abutting plate 105 to move, and the abutting plate 105 abuts the goods to move until the goods abut against the vertical plate 103, and then the motor 115 is started, and the output end of the motor 115 drives the bidirectional threaded rod 114 to rotate, so that the two moving plates 116 move relative to each other, and the two moving plates 116 respectively drive the two clamping plates 117 to move relative to each other, so as to clamp and fix the goods, and then the moving plate 116 is moved relative to each other. The rack 101 moves, driving the goods to move horizontally, and the winch 110 retracts and releases the wire rope 111 to drive the bottom plate 102 to move up and down, thereby driving the goods to move longitudinally, so as to move the goods to the corresponding storage position, and then the bidirectional threaded rod 114 rotates in the opposite direction, so that the two clamping plates 117 move in the opposite direction, and then the sliding sleeve 107 drives the placement plate 104 to move, and the placement plate 104 drives the goods to move into the storage position, and then the winch 110 unwinds the wire rope 111, so that the bottom plate 102 moves downward, and the supporting plate 105 moves to the bottom of the goods, and then the placement plate 104 is retracted, thereby completing the stacking of the goods. This method can effectively solve the problem that the stacker in the prior art is prone to shaking and deviating during the process of transporting the goods, so that the goods will collide with the shelf when placed, thereby causing losses.

[0036] The second embodiment of the present application is:

[0037] Based on the first embodiment, please refer to Figure 4 , Figure 4 It is a schematic structural diagram of the second embodiment of the present invention.

[0038] The present invention provides a stacker, which also includes a support plate 201 , an air duct 202 , a fan 203 and a mounting member, wherein the mounting member includes a fixing plate 204 and two bolts 205 .

[0039] According to this specific embodiment, the support plate 201 is arranged on one side of the vertical plate 103, the air duct 202 passes through the support plate 201 and is fixedly connected to the support plate 201, the fan 203 is arranged inside the air duct 202, and the mounting member is arranged on the upper surface of the support plate 201. When it is used specifically, the support plate 201 and the vertical plate 103 are fixed by the mounting member, and the fan 203 is started to accelerate the air from the air duct 202 to the goods, thereby removing the dust on the upper surface of the goods.

[0040] Among them, the fixing plate 204 is fixedly connected to the supporting plate 201 and is located on the upper surface of the supporting plate 201. The two bolts 205 respectively penetrate the fixing plate 204 and are respectively threadedly connected to the vertical plate 103. When in use, the fixing plate 204 and the vertical plate 103 are fixed by the two bolts 205, thereby fixing the supporting plate 201.

[0041] When a stacker according to the present embodiment is used, when goods are transferred out of a storage location, the fan 203 is started to accelerate the air to blow toward the goods from the air duct 202, thereby removing dust deposited on the goods.

[0042] The third embodiment of the present application is:

[0043] Based on the second embodiment, please refer to Figure 5 , Figure 5 It is a schematic structural diagram of the third embodiment of the present invention.

[0044] The present invention provides a stacker, which also includes two dampers 301 , a buffer plate 302 and two groups of buffer components, each group of the buffer components includes a U-shaped plate 303 and two transverse plates 304 , and each group of the buffer components also includes two buffer pads 305 .

[0045] For this specific embodiment, one end of the two dampers 301 is fixedly connected to the mobile frame 101, and the other end of the two dampers 301 is fixedly connected to the buffer plate 302. The two groups of buffers are symmetrically arranged on the upper surface of the buffer plate 302. When in specific use, when the wire rope 111 breaks, the base plate 102 will fall downward onto the two groups of buffers and generate an impact force on the buffer plate 302. The buffer plate 302 transfers the impact force to the two dampers 301 and weakens the impact force through the two dampers 301.

[0046] Among them, the U-shaped plate 303 is fixedly connected to the buffer plate 302 and is located on the upper surface of the buffer plate 302. The two cross plates 304 are respectively fixedly connected to the U-shaped plate 303. When in use, the impact force generated by the collision between the bottom plate 102 and the cross plate 304 will be transmitted to the buffer plate 302 through the U-shaped plate 303.

[0047] Secondly, the two buffer pads 305 are fixedly connected to the two transverse plates 304 respectively. When in use, the buffer pads 305 can buffer the bottom plate 102 .

[0048] When a stacker according to the present embodiment is used, when the steel wire rope 111 breaks, the base plate 102 will fall downward and collide with the cross plate 304. The impact force generated by the collision between the base plate 102 and the cross plate 304 will be transmitted to the buffer plate 302 through the U-shaped plate 303. The buffer plate 302 will transmit the impact force to the two dampers 301, and the impact force will be weakened by the two dampers 301.
