[0029] In addition, it should be understood that, for the convenience of description, the sizes of the various components shown in the drawings are not drawn in accordance with the actual proportional relationship, for example: the thickness or width of certain layers can be exaggerated relative to other layers.

[0030] It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once an item is defined or described in one drawing, it will not need to be further specifically discussed and described in the description of subsequent drawings.

[0031] To solve the technical problems in the background art, such as Figures 1-7 As shown in the description, the application provides a technical solution: a stainless steel screw conveying device, characterized by:

[0032] The hopper 1 is designed in a symmetrical structure, and an open slot 2 is arranged at the bottom. The open slot 2 is coaxially arranged with the hopper 1 and penetrates through the bottom and one side wall of the hopper 1. A conveying slot 3 is fixedly arranged along the axis of the hopper 1 and located in the open slot 2. The conveying slot 3 is arranged in an inclined manner, and one end located in the hopper 1 is higher than the other end extending out of the hopper 1. The inclined arrangement is conducive to conveying by the screw under the action of gravity. The width of the slot of the conveying slot 3 is designed to be greater than the diameter of the screw shaft and less than the diameter of the screw nut. This design facilitates the screw shaft to extend into the conveying slot 3 while the screw nut is located outside the conveying slot 3. A slope 4 is arranged on both sides of the conveying slot 3. The slope 4 is high near the central axis of the conveying slot 3 and low away from the central axis of the conveying slot 3. When the screw shaft does not fall into the specified position, the slope 4 plays a role in diverting the screw from the end of the conveying slot 3 into the hopper 1. A top block 5 is located in the open slot 2 and on both sides of the conveying slot 3. The top block 5 has an inwardly inclined slope 6, specifically inclined toward the central axis of the conveying slot 3, i.e., the position close to the central axis is lower than the position away from the central axis. A cylinder 7 is connected to one end of the top block 5 and used to drive the top block 5 to reciprocate up and down at the open slot 2. The top block 5 functions to lift the screw out of the bottom of the hopper 1. When the top block 5 is lifted to be higher than the conveying slot 3, the screw slides down the slope 6, which facilitates the smooth entry of the material into the conveying slot 3. A straight vibrator 8 is arranged in the conveying slot 3 and used to vibrate the screw to facilitate the conveying of the screw. A receiving box 9 is connected to one end of the conveying slot 3 and used to collect the screw output from the conveying slot 3.

[0033] When the screw enters from the top of the hopper 1, the screw is concentratedly distributed at the bottom of the hopper 1 due to the symmetrical structure of the hopper 1. The top block 5 reciprocates up and down under the drive of the cylinder 7. When the lowest part of the top surface 12 of the top block 5 is higher than the conveying slot 3, the screw rolls toward the conveying slot 3 under the action of gravity. The straight vibrator 8 vibrates the conveying slot 3 to drive the screw to vibrate, which helps the screw to adjust the position and smoothly fall into the conveying slot 3. Due to the inclined arrangement of the conveying slot 3, the screw moves downward along the slope 6 in the conveying slot 3. The screw enters the receiving box 9 from the other end of the conveying slot 3, and the conveying process is completed.

[0034] It should be noted that the V-shaped block 10 is V-shaped on both sides, the top is narrow, the bottom is wide, and is a limiting device symmetrically arranged on both sides of the conveying chute 3, which ensures that the screw has a tendency to slide on the V-shaped block 10 towards the conveying chute 3, and is conducive to the screw gathering on the conveying chute 3 after sliding. At the same time, the setting of the V-shaped block 10 also increases the number of one-time feeding and improves the efficiency. The V-shaped block 10 has the same inclination as the conveying chute 3, specifically the inclination along the axial direction of the conveying chute 3, that is, one end is higher than the other end, so as to form an adaptation with the conveying chute 3. The two side surfaces 11 of the V-shaped block 10 are respectively connected to the conveying chute 3 and abut against the top block 5, ensuring the mutual cooperation of the V-shaped block 10 with the two.

[0035] It should be noted that, as shown in the figure, the notch 13 is located at the lower end of the V-shaped block 10. The shape of the notch 13 is a cuboid, and the upper surface of the V-shaped block 10 at the notch 13 is lower than the conveying chute 3, which is conducive to the screw on the conveying chute 3 falling through the notch 13 after sliding off the slope 4 and falling into the hopper 1.

[0036] Further, when the top block 5 is at the lowest point, the highest point of the inclined surface 6 is flush with the edge of the open slot 2, facilitating the screw in the hopper 1 to slide down into the inclined surface 6 of the top block 5; when the top block 5 is at the highest point, the lowest point of the inclined surface 6 is higher than the highest point of the top surface 12 of the V-shaped block 10, facilitating the screw on the inclined surface 6 to slide down and roll into the top surface 12 of the V-shaped block 10, and then into the conveying chute 3.

[0037] It should be noted that the limiting block 14 is arranged at the bottom end of the hopper 1 and is used to limit the movement direction of the top block 5. Specifically, the limiting block 14 is C-shaped, and its two ends respectively hold the top block 5. Two limiting blocks 14 respectively cooperate with two top blocks 5 to form a sliding groove that limits the movement of the top block 5 in the vertical direction, thereby ensuring that the screw is regularly lifted upward.

[0038] It should be noted that the alignment block 15 is arranged at the lower end of the conveying chute 3 and is used to align the screw on the conveying chute 3. The alignment block 15 has a through hole 16 for accommodating a screw cap, and the through hole 16 is located at the central position of the alignment block 15. The diameter of the through hole 16 is adapted to the size of the screw cap to ensure that the screw cap can be smoothly inserted and fixed.

[0039] It should be noted that the guide surface 17 is arranged on the alignment block 15, specifically connected to the alignment block 15, and symmetrically arranged along the axial direction of the conveying chute 3. The two guide surfaces 17 are respectively located on both sides of the alignment block 15, forming a horn-shaped structure. The distance between the two guide surfaces 17 away from the alignment block 15 is large, and the distance between the two guide surfaces 17 close to the alignment block 15 is small.

[0040] The guiding surface 17 is a flat surface, and the minimum distance between the two guiding surfaces 17 is not less than the width of the through hole 16, so as to ensure that the screw rod can smoothly enter the through hole 16 when passing through the guiding surface 17. The guiding surface 17 has good wear resistance and corrosion resistance, and can be made of plastic or stainless steel.

[0041] It should be noted that the stopper 18 is arranged on the alignment block 15, specifically, the two are hinged. The stopper 18 can rotate around the hinge shaft. The specific structure of the stopper 18 is a thin piece formed by a square and a round connection, and the diameter of the end of the round is slightly larger than the width of the through hole 16. The function of the stopper 18 is to limit the screw rod to pass through the through hole 16, thereby achieving the stop function, and further achieving the intermittent switching of the material box 9.

[0042] Although the embodiments of the present application have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
