Description

Technical Field

[0001] This utility model relates to the field of powder packaging, and in particular to a vertical screw cutting gate mechanism. Background Technology

[0002] In existing technologies, material gate mechanisms are key components for controlling material discharge during powder packaging and conveying processes in industries such as chemicals, food, and building materials. Currently, common material gates on the market mainly include traditional types such as manual gate valves, pneumatic slide gates, and electric butterfly valves. Manual gate valves rely on manual operation for opening and closing, depending on the operator's experience. This is not only labor-intensive but also makes it difficult to precisely control the discharge speed and flow rate, easily leading to uneven powder discharge and affecting the accuracy and efficiency of material packaging. While pneumatic slide gates and electric butterfly valves achieve automated control, they still have many problems in practical applications. These types of material gates typically open or close completely, making it impossible to finely adjust the discharge port opening. This can easily lead to excessive instantaneous flow during discharge, causing powder accumulation or dust pollution. Furthermore, when handling easily agglomerated and highly viscous powders, the sealing structure of traditional material gates is easily jammed by the material, resulting in incomplete closure and leakage. This not only wastes materials but may also cause safety hazards and environmental pollution. Utility Model Content

[0003] This application provides a vertical screw cutting gate mechanism, which solves the problem in the prior art where the moving gate is opened and closed manually. This relies on the operator's experience to control the opening, which is not only labor-intensive, but also makes it difficult to accurately control the discharge speed and flow rate, which can easily lead to uneven powder discharge and affect the accuracy and efficiency of material packaging.

[0004] The technical solutions adopted in the embodiments of this application are as follows.

[0005] A vertical screw material cutting gate mechanism includes a first pushing member, a discharge pipe disposed at the actuating end of the first pushing member, a material pipe connected to the discharge pipe, a moving member for uniformly moving the material, and a sealing member for sealing or opening the discharge pipe; a discharge groove is formed inside the discharge pipe; one end of the material pipe is connected to the discharge groove, and the other end is connected to a hopper; the moving member rotates inside the discharge pipe; the bottom of the discharge groove is open; the sealing member is disposed on the discharge pipe, and the actuating end of the sealing member corresponds to the bottom of the discharge pipe.

[0006] As a further improvement to the above technical solution:

[0007] The moving component includes a driving component, a rotating rod that rotates at the working end of the driving component, and a spiral blade that moves the material; the spiral blade is disposed on the rotating rod; the driving component drives the spiral blade to rotate in contact with the discharge trough.

[0008] The sealing element includes a second pusher, a connecting plate disposed on the second pusher, a sealing plate for sealing the discharge groove, and a connecting rod for rotating the sealing plate; the second pusher is disposed on the discharge pipe; one end of the connecting rod is connected to the connecting plate, and the other end is hinged to the sealing plate; two sets of sealing plates are disposed opposite to the connecting rod, and the sealing plates are hinged to the bottom of the discharge groove, corresponding to the bottom of the discharge pipe.

[0009] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0010] 1. By employing a drive mechanism to rotate the spiral blades within the discharge trough, the rotation speed can be flexibly adjusted according to material characteristics and production needs, achieving stepless and precise control of the discharge port opening. Compared to the fully open / fully closed modes of traditional material gates, this mechanism can linearly adjust the powder discharge speed, avoiding accumulation or dust caused by excessive instantaneous flow. It is particularly suitable for powder conveying scenarios such as food and pharmaceuticals where high packaging precision is required. The continuous rotation of the spiral blades effectively breaks up easily agglomerated powder clumps. Combined with the opening design at the bottom of the discharge trough, this ensures that the material is discharged at a uniform flow rate. When handling highly viscous powders, the close rotation of the spiral blades against the inner wall of the discharge trough prevents material adhesion and accumulation, ensuring a continuous and stable discharge process and solving the problem of incomplete closure caused by material jamming in traditional material gates. The sealing element drives the connecting plate via a second pusher, which in turn drives two sets of sealing plates to rotate synchronously and adhere to the bottom of the discharge pipe, forming a double sealing structure. This design effectively blocks powder leakage paths, maintaining good sealing performance even when handling highly fluid powders, reducing material waste while avoiding environmental pollution and safety hazards.

[0014] This application provides a vertical screw cutting gate mechanism, which solves the problem in the prior art where the moving gate is opened and closed manually. This relies on the operator's experience to control the opening, which is not only labor-intensive, but also makes it difficult to accurately control the discharge speed and flow rate, which can easily lead to uneven powder discharge and affect the accuracy and efficiency of material packaging.

[0015] The technical solution in this application embodiment is to solve the above problems, and the overall idea is as follows:

[0016] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0017] A vertical screw material cutting gate mechanism includes a first pushing member 1, a discharge pipe 2 disposed at the active end of the first pushing member 1, a material pipe 3 connected to the discharge pipe 2, a moving member 4 for uniformly moving the material, and a sealing member 5 for sealing or opening the discharge pipe 2; a discharge groove 21 is provided inside the discharge pipe 2; one end of the material pipe 3 is connected to the discharge groove 21, and the other end is connected to a hopper; the moving member 4 rotates inside the discharge pipe 2; the bottom of the discharge groove 21 is open; the sealing member 5 is disposed on the discharge pipe 2, and the active end of the sealing member 5 corresponds to the bottom of the discharge pipe 2.

[0018] The moving part 4 includes a driving part 41, a rotating rod 42 rotating at the working end of the driving part 41, and a spiral blade 43 that drives the material to move; the spiral blade 43 is disposed on the rotating rod 42; the driving part 41 drives the spiral blade 43 to rotate in contact with the discharge trough 21.

[0019] The sealing element 5 includes a second pusher 51, a connecting plate 52 disposed on the second pusher 51, a sealing plate 53 sealing the discharge groove 21, and a connecting rod 54 that drives the sealing plate 53 to rotate; the second pusher 51 is disposed on the discharge pipe 2; one end of the connecting rod 54 is connected to the connecting plate 52, and the other end is hinged to the sealing plate 53; two sets of sealing plates 53 and connecting rods 54 are disposed opposite each other, and the sealing plates 53 are hinged to the bottom of the discharge groove 21, corresponding to the bottom of the discharge pipe 2.

[0020] Because the spiral blades 43 are driven by the drive component 41 to rotate within the discharge trough 21, the rotation speed can be flexibly adjusted according to material characteristics and production needs, achieving stepless and precise control of the discharge port opening. Compared to the fully open / fully closed mode of traditional material gates, this mechanism can linearly adjust the powder discharge speed, avoiding accumulation or dust caused by excessive instantaneous flow, making it particularly suitable for powder conveying scenarios such as food and pharmaceuticals where high packaging precision is required. The continuous rotation of the spiral blades 43 can effectively break up easily agglomerated powder clumps, and combined with the opening design at the bottom of the discharge trough 21, it allows the material to be discharged at a uniform flow rate. When handling highly viscous powders, the contact and rotation between the spiral blades 43 and the inner wall of the discharge trough 21 can prevent material adhesion and accumulation, ensuring a continuous and stable discharge process and solving the problem of incomplete closure caused by material jamming in traditional material gates. The sealing component 5 drives the connecting plate 52 through the second push component 51, and through the connecting rod 54, drives the two sets of sealing plates 53 to rotate synchronously and contact the bottom of the discharge pipe 2, forming a double sealing structure. This design effectively blocks powder leakage paths, maintaining good sealing performance even when handling highly fluid powders, reducing material waste while avoiding environmental pollution and safety hazards.
