The material distributing baffle has an arc surface portion which is curved towards the center of the vibrating disc along the material conveying direction. The distance between the material distributing baffle and the first track section is greater than the height of the insulation sleeve and less than the maximum diameter of the insulation sleeve.

[0011] The second material selecting track is provided with a material passing groove.

Based on the embodiments in the utility model, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the utility model.

[0024] As Figure 2 and Figure 3 shown, an automatic loading device for insulation sleeve for defrosting heater, including vibration disc 2, receiving seat 4 and clamping assembly, the outlet side of the vibration disc 2 has the downwardly inclined arrangement and makes insulation sleeve 10 transverse passage 3, as Figure 1 shown, since the insulation sleeve 10 for defrosting heater has its unique structure, it is the cylinder piece with outer diameter 6mm, height 4mm, one end opening, the middle part of the insulation sleeve 10 is provided with the through hole for the lead-out rod 9 to pass through, in order to ensure that the opening of each insulation sleeve 10 conveyed to the discharge channel 3 by the vibration disc 2 is oriented in the same direction, in turn, to ensure the correctness of semi-finished product assembly, the vibration disc 2 is sequentially provided with a first material selection track for screening insulation sleeve 10 standing on the track, a second material selection track for screening insulation sleeve 10 with upwardly open cylinder and a reversing track for converting insulation sleeve 10 from vertical transportation to horizontal transportation along the material conveying direction. As Figure 4 shown, the first material selection track includes a first track section connected with the spiral feeding track 201 in the vibration disc 2 and a material distribution baffle 202 fixed above the track, the material distribution baffle 202 has an arc surface portion curved towards the center of the vibration disc 2 along the material conveying direction, the distance between the material distribution baffle 202 and the first track section is greater than the height of the insulation sleeve 10 and less than the maximum diameter of the insulation sleeve 10, since the outer diameter of the insulation sleeve 10 is greater than the height, the insulation sleeve 10 not standing through the first track section falls into the vibration disc 2 for re-screening under the block of the material distribution baffle 202; as Figure 4As shown, the second material selection track is provided with a material passing groove, and a plurality of material passing teeth 203 are arranged in the material passing groove along the material conveying direction. The width of the material passing teeth 203 is smaller than the cylindrical opening size of the insulating sleeve 10. The insulating sleeve 10 vertically passing through the first material selection track includes two cases of downward opening and upward opening. When the opening of the insulating sleeve 10 is downward, it will fall into the vibration disc 2 for re-screening after passing through the material passing teeth 203. Figure 4 As shown, the insulating sleeve 10 screened through the second material selection track is vertically arranged and upwardly opened. After passing through the reversing track, the vertically arranged insulating sleeve 10 becomes horizontally arranged after turning on the reversing track, so as to enter the discharge channel 3. In order to avoid the insulating sleeve 10 falling into the vibration disc 2 during the reversing process, the vertical material inlet 204 is fixed with an abutting plate 206 close to the center side of the vibration disc 2.

[0025] As shown, Figure 5 As shown, the material receiving seat 4 is fixed outside the discharge port of the discharge channel 3, and the material receiving seat 4 is provided with a material receiving groove 401 connected with the discharge channel 3. The clamping assembly includes a pressing plate 6 above the material receiving groove 401 and a clamping cylinder 5 driving the pressing plate 6 to move close to / distance from the material receiving groove 401. The lower surface of the pressing plate 6 is provided with a pressing groove 601, and the inner side of the material receiving groove 401 is also arc-shaped, which cooperates to form a clamping channel for clamping the insulating sleeve 10. By installing the material receiving seat 4 provided with the material receiving groove 401 on the discharge port of the discharge channel 3, the insulating sleeve 10 in the discharge channel 3 will fall into the material receiving groove 401 one by one. This position is the feeding position of the insulating sleeve 10 for assembling with the lead-out rod 9. The clamping and positioning of the insulating sleeve 10 are completed by the cooperation of the pressing groove 601 of the pressing plate 6 and the material receiving groove 401 of the material receiving seat 4. The existing pushing mechanism 8 pushes the lead-out rod 9 to complete the assembly. Due to the arc-shaped groove, the insulating sleeve 10 is uniformly stressed and does not deform, thereby ensuring the quality of the semi-finished product after assembly.

[0026] Further preferably, the material receiving seat 4 is provided with a material receiving sensor 7. The sensing end of the material receiving sensor 7 penetrates through the material receiving seat 4 and communicates with the material receiving groove 401. The wiring end of the material receiving sensor 7 is communicatively connected with the clamping cylinder 5 through a control unit. The control unit receives signals from the material receiving sensor 7 to control the action of the clamping cylinder 5.

[0027] As shown, Figure 5As shown, the surface of the receiving groove 401 and the pressing groove 601 is fixed with a limiting weld 402 for limiting the axial movement of the limiting insulation sleeve 10. By the limiting effect of the limiting weld 402, the distance between the pressing plate 6 and the receiving seat 4 in the clamping state can be relatively reduced, that is, the clamping force generated by the clamping channel on the insulation sleeve 10 is reduced, and the probability of deformation of the insulation sleeve 10 due to clamping is further avoided.

[0028] When the above technical solution is implemented, the device and the existing push mechanism 8 are installed on the rack 1 together. The existing push mechanism 8 can be a feeding device based on the lead-out rod 9 disclosed in the patent CN213916934U. The feeding device controls the telescopic rod to push the lead-out rod 9 in the slide to move in the horizontal direction through the telescopic motor. The slide is coaxially arranged with the receiving groove 401 of the device. When assembling, the insulation sleeve 10 is poured into the vibration disc 2. The insulation sleeve 10 is arranged in the horizontal and cylindrical opening with the barrel opening facing away from the side of the push mechanism 8 after passing through the spiral feeding track 201, the first material selection track, the second material selection track and the reversing track, and is arranged into the discharging channel 3. Under the action of gravity, the insulation sleeve 10 slides into the receiving groove 401. The receiving sensor 7 detects the insulation sleeve 10. The control unit (PLC) controls the clamping cylinder 5 to act. The pressing plate 6 moves close to the receiving groove 401 and clamps the outside of the insulation sleeve 10 together with the receiving groove 401. The push mechanism 8 pushes the lead-out rod 9, so that the lead-out rod 9 is inserted into the through hole of the insulation sleeve 10. The control unit (PLC) controls the clamping cylinder 5 to reset, takes out the assembled semi-finished product from the receiving groove 401, and the next insulation sleeve 10 falls into the receiving groove 401 under the action of gravity for cyclic operation. There is no phenomenon of missing material or jamming. There is no extrusion deformation phenomenon on the insulation sleeve 10 of the semi-finished product.

[0029] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. For those skilled in the art, the present application can be variously changed and modified. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
