DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the utility model.

[0036] Please refer to Figures 1-6In this embodiment of the present invention, an automatic plastic powder feeding device includes a support frame 10, a feeding hopper 11 rotatably connected to the top of the support frame 10, a conveying pipe 12 fixedly connected to the outside of the feeding hopper 11, a spiral frame 121 rotatably connected inside the conveying pipe 12, a support shell 13 slidably connected to the inside of the support frame 10, a guide shell 131 fixedly connected to the top of the support shell 13, a limiting module 14 disposed on the top of the support frame 10, the limiting module 14 being able to limit the feeding hopper 11, and an auxiliary module 15 disposed inside the support frame 10, the auxiliary module 15 being able to automatically clean the guide shell 131.

[0037] Specifically, a conveying pipe 12 is fixedly connected to the outer wall of the feeding hopper 11. The conveying pipe 12 can be rotated and its position adjusted to supply materials to different equipment. It can be flexibly applied according to the needs of the production line, saving costs. The conveying pipe 12 is stably limited by inserting the rod 144 into the retaining ring 141 to prevent the material supply position of the conveying pipe 12 from deviating. Activating the hydraulic rod 133 can lower the guide shell 131 as a whole and expose it. The top of the guide shell 131 can be automatically cleaned by blowing air through the two air guide seats 154, saving manpower and making it convenient to use.

[0038] Example 1

[0039] like Figures 1-5 As shown, in this embodiment, a limiting rod 132 is fixedly connected to the inner bottom surface of the support frame 10. The limiting rod 132 passes through the support shell 13 and is slidably connected to it. Two hydraulic rods 133 are fixedly connected to the inner bottom surface of the support frame 10. Two fixing plates 134 are symmetrically fixed to the outer wall of the support shell 13. The output end of the hydraulic rod 133 is fixedly connected to the adjacent fixing plate 134. The auxiliary module 15 includes baffles 153. Multiple baffles 153 are provided. The baffles 153 are fixedly connected to the inner top surface of the support frame 10. Guide seat 151 and guide seat 2 152 are both fixedly connected to the adjacent baffles 153. The top of the protective shell 1531 is fixedly connected to the adjacent fixing plate 134. Multiple air guide seats 154 are provided. The air guide seat 154 is fixedly connected to the adjacent guide seat 151. The fan 155 is fixed to the top of the air guide seat 154. The air outlet of the fan 155 passes through the air guide seat 154 and extends into its interior.

[0040] In this embodiment, the support shell 13 is vertically limited by the limiting rod 132. Activating the two hydraulic rods 133 moves the support shell 13 and guide shell 131 downwards as a whole, allowing the guide shell 131 to leak out of the feeding hopper 11, thus cleaning the powder remaining on the top of the guide shell 131. Activating the hydraulic rods 133 moves the support shell 13 and guide shell 131 downwards as a whole until the top of the guide shell 131 is flush with the guide seat 151 and guide seat 2 152. Multiple baffles 153 block the sides of the guide shell 131, limiting the movement path of the powder. Activating the two fans 155 blows air into the air guide seat 154, blowing away the residual powder on the top of the guide shell 131, thus automatically cleaning the powder on the top of the guide shell 131.

[0041] like Figure 2 As shown, in this embodiment, one end of each of the two guide seats 152 is fixedly connected to an exhaust duct 156, the bottom of the exhaust duct 156 is rotatably connected to a flap door 158, a mesh plate 159 is fixedly embedded on one side of the exhaust duct 156, and a dust collection bag 157 is provided inside the exhaust duct 156.

[0042] In practice, the blown-down distribution is concentrated and guided by the exhaust duct 156, and the dust is collected by the dust collection bag 157. Air is discharged to the outside through the mesh plate 159, and the dust collection bag 157 can be replaced and cleaned by opening the trapdoor 158.

[0043] Example 2

[0044] Based on Example 1, in order to achieve stable positioning after the rotation and adjustment of the conveying pipe 12 is completed, and to prevent the position of the conveying pipe 12 from shifting during operation.

[0045] like Figures 3-6 As shown, in this embodiment, a positioning ring 101 is fixedly embedded in the top of the support frame 10, and a limiting ring 111 is fixedly connected to the bottom of the feeding hopper 11. The limiting ring 111 is rotatably connected to the positioning ring 101. Multiple balls 112 are rotatably connected at equal intervals at the bottom of the limiting ring 111. The limiting module 14 includes a retaining ring 141, which is fixedly connected to the top of the support frame 10. Multiple slots 142 are equidistantly opened on the top of the retaining ring 141. A sliding ring 143 is slidably connected to the outer wall of the feeding hopper 11. Multiple insert rods 144 are provided. The top end of the insert rod 144 is fixedly connected to the sliding ring 143, and the bottom end of the insert rod 144 can be movably engaged with the adjacent slot 142. A second hydraulic rod 145 is fixedly connected to the outer wall of the feeding hopper 11, and the output end of the second hydraulic rod 145 is fixedly connected to the bottom of the sliding ring 143.

[0046] In specific implementation, the rotation of the feeding hopper 11 is limited by the limiting of the limiting ring 111 by the positioning ring 101, so that the feeding hopper 11 can drive the whole material conveying pipe 12 to rotate, the position of the material conveying pipe 12 can be adjusted to supply different equipment, the ball 112 facilitates reducing the friction between the limiting ring 111 and the positioning ring 101, so that the rotation of the feeding hopper 11 is more smooth, after the feeding hopper 11 drives the material conveying pipe 12 to rotate and adjust the position, the positions of the two inserting rods 144 are changed immediately, the hydraulic rod two 145 is started to drive the whole sliding ring 143 to move downward, the two inserting rods 144 are clamped into the inner part of the clamping groove 142, so that the feeding hopper 11 is limited, and the whole material conveying pipe 12 is stabilized, because the unit will vibrate slightly during operation, the material conveying pipe 12 is limited to prevent the vibration from causing the feeding hopper 11 to rotate and deviate, and affecting the discharging position of the material conveying pipe 12.

[0047] It is apparent for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, but can be implemented in other concrete forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all aspects as illustrative and not restrictive, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and range of equivalent elements of the claims are intended to be embraced in the present application. Any reference signs in the claims should not be considered as limiting the claims involved.

[0048] In addition, it should be understood that, although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be combined appropriately to form other embodiments that those skilled in the art can understand.
