Description

Technical Field

[0001] This application relates to the technical field of filling machines, and in particular to an anti-clogging filling head for automatic filling machines containing granular materials. Background Technology

[0002] In the process of automatic filling machines handling materials containing granules, traditional filling methods often result in granules sticking and accumulating at the end of the feed pipe, causing blockages in the filling channel and affecting filling efficiency and accuracy. Traditional filling machines typically have fixed filling heads, which cannot effectively solve the material sticking problem, requiring frequent machine stops for cleaning. This increases production downtime and labor costs, especially for granules containing sticky components, where the problem is more pronounced and severely restricts the continuity and stability of the filling production line. Therefore, to solve the above problems, this application provides an anti-clogging filling head for automatic filling machines containing granules. Utility Model Content

[0003] To address the aforementioned issues, this application provides an anti-clogging filling head for automatic filling machines containing granular materials.

[0004] This application provides an automatic filling machine with an anti-clogging filling head for granular materials, characterized in that it includes a feeding pipe, an inner receiving plate, a feeding screw, and support rods; the feeding screw is electrically driven and disposed inside the feeding pipe, the inner receiving plate is disposed at the end of the feeding pipe, and the support rods are evenly distributed at the front end of the feeding screw along its axial direction.

[0005] Preferably, the top of the inner receiving piece is elastically connected to the conveying pipe via an elastic connecting section, and its bottom end is provided with a chamfered section.

[0006] Preferably, the inner flap is tapered inward at an angle of 15-20°.

[0007] Preferably, when the feeding screw rotates, the support rod can contact the chamfered section of the inner retracting plate, so that the inner retracting plate can open and close.

[0008] Preferably, the support rods are evenly distributed circumferentially along the front end of the conveying screw.

[0009] Preferably, the opening and closing action of the inner retractor can maintain the movement of the end of the feed tube, reduce the possibility of material sticking, and improve the filling effect.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] By installing a support rod at the front end of the conveying screw, and cooperating with an inner retractor plate with an elastic connection structure at the end, the rotation of the conveying screw drives the support rod to contact the chamfered section of the inner retractor plate, causing the inner retractor plate to continuously open and close, thereby maintaining the dynamic movement of the end of the conveying pipe. This design fundamentally reduces the adhesion and accumulation of particulate materials at the end of the conveying pipe, effectively avoiding blockage of the filling channel, and significantly improving the continuity and stability of the filling process; at the same time, it reduces the frequency of downtime for cleaning, saves labor costs, and improves filling efficiency and accuracy, and is especially suitable for processing particulate materials containing sticky components.

[0016] The following is in conjunction with the appendix Figure 1 - Figure 3 This application will be described in further detail.

[0017] Example 1:

[0018] An automatic filling machine with an anti-clogging filling head for granular materials, as described in the reference. Figure 1 - Figure 3 ,like Figure 1 As shown, it includes a conveying pipe 1, an inner receiving plate 2, a conveying screw 3, and a support rod 4. The conveying screw 3 is driven by a motor and is located inside the conveying pipe 1. It can rotate along its own axis to convey materials containing particles.

[0019] The inner retractor 2 is located at the end of the feed pipe 1, and its top end is elastically connected to the feed pipe 1 through an elastic connecting section 21. The elastic connecting section 21 can be made of rubber or a spring structure, so that the inner retractor 2 has a certain elastic movement space. The bottom end of the inner retractor 2 is provided with a chamfered section 22, which is a smoothly transitioned inclined surface, so as to facilitate contact with the support rod 4.

[0020] The inner retractor 2 is angled inward at 15-20° to form a structure with a slightly narrower end, which is conducive to the concentrated output of materials and provides a basis for subsequent opening and closing actions.

[0021] Support rod 4 is arranged along the axial direction of the conveying screw 3 at its front end and is evenly distributed along the circumference of the conveying screw 3. The number of support rods 4 can be set to 3-6 according to actual needs, and its length should be such that it can contact the chamfered section 22 of the inner receiving plate 2.

[0022] In actual operation, when the feeding screw 3 rotates under the drive of the motor, the support rod 4 at its front end rotates along with it. Since the support rod 4 is evenly distributed circumferentially, it will continuously and alternately contact the chamfered section 22 of the inner retracting piece 2 during rotation. When the support rod 4 contacts the chamfered section 22, it will exert an outward pushing force on the inner retracting piece 2, causing the inner retracting piece 2 to overcome the elastic force of the elastic connecting section 21 and open outward; when the support rod 4 passes the chamfered section 22, the pushing force disappears, and the inner retracting piece 2 returns to its initial retracted state under the action of the elastic connecting section 21.

[0023] Through the above process, the inner retractor 2 achieves continuous opening and closing, keeping the end of the conveying pipe 1 in a constantly moving state. This moving state effectively prevents the adhesion and accumulation of particulate materials at the end of the conveying pipe 1, reducing the occurrence of blockages, thereby ensuring the continuity and stability of the filling process and significantly improving the filling effect.

[0024] The foregoing description of an exemplary embodiment of an automatic filling machine containing particulate materials with an anti-clogging filling head provided by this disclosure has been described with reference to preferred embodiments. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
