Technical Field

[0001] The utility model relates to the technical field of PE pipe production, in particular to a raw material drying device used for PE water pipe production. Background Art

Therefore, there is an urgent need for a raw material drying equipment for PE water pipe production that can automatically feed raw materials, save time and labor, and improve feeding efficiency.

[0034] A connecting plate 6 is movably connected to the frame 1 in a vertical direction. A hydraulic cylinder 61 is provided on the connecting plate 6. The axial direction of the hydraulic cylinder 61 is in a vertical direction. The weighing block 5 is connected to the piston rod of the hydraulic cylinder 61. A metal baffle 62 is provided at the lower part of the connecting plate 6.

[0035] A driving member, the driving member is used to drive the connecting plate 6 to move, so that the balancing plate 4 switches between the first state and the second state;

[0036] In the first state, the weighing block 5 abuts against the Y direction of the pivot axis of the balance plate 4 , and the proximity switch 51 is separated from the metal blocking piece 62 .

[0037] In the first state, the raw material falls onto the balance plate 4. When the mass of the raw material is greater than the compression potential energy of the weighing block 5 and the hydraulic rod piston rod, one end of the pivot axis X of the balance plate 4 lifts up the weighing block 5, and the proximity switch 51 of the weighing block 5 touches the metal baffle 62.

[0038] In the second state, the weighing block 5 is located above the pivot axis Y of the balancing plate 4 , and the proximity switch 51 is disengaged from the metal blocking piece 62 .

[0039] A controller is electrically connected to the solenoid valve 321 , the driving element and the proximity switch 51 .

[0040] In the above embodiment, the driving member drives the connecting plate 6 to switch to the first state, and the raw material enters from the feed pipe 32. When the raw material is accumulated and the balance plate 4 is close to one end of the feed pipe 32, when the mass of the raw material is greater than the weight of the weighing block 5 and the compression potential energy of the hydraulic cylinder 61, the weighing block 5 is lifted up, and when the proximity switch 51 of the weighing block 5 touches the metal baffle 62, the proximity switch 51 transmits a signal to the controller, and the controller controls the driving member to drive the connecting plate 6 to switch to the second state. The controller controls the electromagnetic closure, and the raw material falls from the opposite end of the balance plate 4X to the discharge port 31 of the feeding box 3. After a preset period of time, the controller controls the solenoid valve 321 to open. At the same time, the controller controls the driving member to drive the connecting plate 6 to switch to the first state. Compared with the prior art, the raw materials can be automatically delivered, saving time and effort, and improving the delivery efficiency.

[0044] As an optional implementation, the feeding box 3 is provided with a clamping member 10 , and the clamping member 10 is located above the pivot axis X direction of the balancing plate 4 .

[0045] In the above embodiment, when the driving member drives the connecting plate 6 to switch to the first state, the clamping member 10 is provided to prevent the balancing angle from being too large, so that one end of the pivot axis X of the balancing plate 4 is located above the pivot axis, resulting in the inability to abut against the pivot axis X of the balancing plate 4 when the scale moves downward.

[0046] As an optional embodiment, a plurality of drying plates 24 distributed in the vertical direction are provided in the drying box 2, the inclination directions of two adjacent drying plates 24 are opposite, the angle between the drying plate 24 and the horizontal plane is 45-60°, and the discharge port 21 is connected to the end of the drying plate 24 near the drying bottom.
