Description

Technical Field

[0001] This utility model belongs to the field of material feeding technology, and in particular relates to a material feeding device for adhesive materials. Background Technology

[0002] Currently, in the extrusion industry, when granular raw materials are transported to the silo and then fed into the extruder, some materials often clump together due to either the quality of the granular material itself or the addition of auxiliary materials and various additives.

[0003] During the feeding process, to facilitate keeping up with the production line's capacity and speed, the feeding of materials is controlled. Two commonly used feeding methods are rotary screw feeding and vibrating screen feeding. However, when granular materials clump together, rotary screw feeding results in uneven clump size, preventing the material from flowing smoothly into subsequent equipment and causing it to accumulate at the feed inlet. Vibrating screen feeding, on the other hand, suffers from uneven weight distribution due to clumps, causing fluctuations in the weighing unit's readings. This signal is fed back to the vibration unit, resulting in erratic vibration and feeding fluctuations. Therefore, a structure capable of breaking up clumps of material is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an adhesive material feeding device, which solves the aforementioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a material feeding device for adhesives, comprising a dynamic pressure rod, a reciprocating assembly, and a rotating assembly. Multiple dynamic pressure rods are symmetrically and horizontally arranged in a horizontal tube, with the dynamic pressure rods on the upper and lower sides of the horizontal tube respectively close to the upper and lower side walls. Multiple static pressure rods are symmetrically and fixedly connected within the horizontal tube, and these static pressure rods are inclined within the horizontal tube, with the dynamic pressure rod positioned between two adjacent static pressure rods. A raw material conveying pipe is vertically and fixedly connected to the upper end face of the horizontal tube. After the dynamic pressure rod is inserted between two adjacent static pressure rods, the distance between the dynamic pressure rod and the static pressure rods on both sides is maintained at approximately the average diameter of the material particles. The reciprocating assembly is used to periodically insert the dynamic pressure rod between its corresponding static pressure rod. The rotating assembly is used to make the dynamic pressure rod rotate at a uniform speed.

[0006] Beneficial effects

[0007] This utility model provides a feeding device for adhesive materials, which has the following advantages compared with the prior art:

[0008] 1. The user feeds the raw material into the top opening of the raw material conveying pipe. Since the raw material conveying pipe is vertically set on the horizontal pipe, under the action of the raw material's gravity, on the one hand, the raw material continuously enters the pushing range of the dynamic pressure bar. On the other hand, the raw material extruded from the static pressure bar will fall and move away quickly under its own gravity and the pushing of the following raw material. During this process, the user uses the reciprocating component to make the dynamic pressure bar start to reciprocate. At this time, multiple dynamic pressure bars are inserted into their corresponding static pressure bars in a cycle. Since there is an angle between the dynamic pressure bar and the static pressure bar, shearing pressure can be generated when the dynamic pressure bar pushes the raw material to enhance the squeezing effect. This increases the breaking effect on the clumped raw material when it passes through the static pressure bar. At the same time, since the dynamic pressure bar is tubular, even if raw material falls on it when it is in the horizontal pipe, it can fall off through the gap between adjacent dynamic pressure bars, thus avoiding affecting the falling of the raw material. During the retraction of the dynamic pressure bar, if there is clumped material stuck on it, it can be scraped off by the action of the side wall of the horizontal pipe. Attached Figure Description

Detailed Implementation

[0014] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0015] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0016] Please see Figures 1-4This invention provides an embodiment of an adhesive material feeding device, comprising a dynamic pressure rod 201, a reciprocating assembly, and a rotating assembly. Multiple dynamic pressure rods 201 are symmetrically and horizontally arranged in a horizontal tube 101, with the dynamic pressure rods 201 on the upper and lower sides of the horizontal tube 101 respectively close to the upper and lower side walls of the horizontal tube 101. Multiple static pressure rods 202 are symmetrically and fixedly connected inside the horizontal tube 101, and the multiple static pressure rods 202 are inclinedly arranged inside the horizontal tube 101. The dynamic pressure rod 201 is positioned between two adjacent static pressure rods 202. A raw material conveying pipe 203 is vertically and fixedly connected to the upper end face of the horizontal tube 101. After the dynamic pressure rod 201 is inserted between two adjacent static pressure rods 202, the distance between the dynamic pressure rod 201 and the static pressure rods 202 on both sides is maintained at a distance of 2 to 3 times the average diameter of the granules.

[0017] The reciprocating assembly is used to periodically insert the dynamic pressure rod 201 between its corresponding static pressure rod 202; the rotating assembly is used to make the dynamic pressure rod 201 rotate at a uniform speed.

[0018] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific horizontal tube 101 described in the above embodiments. For example, the length of the horizontal tube 101 should be shortened as much as possible. The purpose of this arrangement is to facilitate the avoidance of particle accumulation in the horizontal tube 101.

[0019] In the above embodiment, the user feeds the raw material into the top opening of the raw material conveying pipe 203. Since the raw material conveying pipe 203 is vertically installed on the horizontal pipe 101, under the action of the raw material's gravity, on the one hand, the raw material continuously enters the pushing range of the dynamic pressure rod 201; on the other hand, the raw material extruded from the static pressure rod falls and moves away quickly under its own gravity and the pushing force of the following raw material. During this process, the user uses the reciprocating assembly to make the dynamic pressure rod 201 start to reciprocate, that is, at this time, multiple dynamic pressure rods 201 are cyclically inserted between their corresponding static pressure rods 202. At this time, due to the dynamic pressure... The dynamic pressure rod 201 and the static pressure rod 202 are at an angle, so when the dynamic pressure rod 201 pushes the raw material, it can generate shear pressure to enhance the squeezing effect, so that when the agglomerated raw material passes through the static pressure rod 202, the agglomerated raw material is broken up. At the same time, since the dynamic pressure rod 201 is tubular, when it is inside the horizontal tube 101, even if raw material falls on it, it can fall off through the gap between adjacent dynamic pressure rods 201, thus avoiding affecting the falling of the raw material. Furthermore, during the retraction of the dynamic pressure rod 201, if there is agglomerated material stuck on it, it can be scraped off by the action of the side wall of the horizontal tube 101.

[0020] Specifically, the rotating assembly includes a threaded section 205 and a sleeve 204. Multiple threaded sections 205 are respectively disposed on their corresponding dynamic pressure rods 201, and the threaded sections 205 are lead screws without self-locking effect. The threaded sections 205 pass through the sleeves 204 and are threadedly connected to the sleeves 204. Elliptical heads 206 are fixedly connected to the ends of the multiple dynamic pressure rods 201.

[0021] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific sleeve 204 described in the above embodiments. For example, the sleeve 204 is provided with a rubber sleeve at the pipe opening inside the horizontal tube 101, and the rubber sleeve is tightly attached to the surface of the threaded section 205. The rubber sleeve is used to prevent the raw material from entering the sleeve 204 along with the threaded section 205.

[0022] Regarding the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific elliptical head 206 described in the above embodiments. For example, the elliptical head 206 is wrapped with a rubber ring. The purpose of this setting is to avoid damage to the raw materials.

[0023] In the above embodiment, when the dynamic pressure rod 201 is reciprocating, since the threaded section 205 provided on it does not have a self-locking effect, and the threaded section 205 is threadedly connected to the sleeve 204, the threaded section 205 drives the dynamic pressure rod 201 to start rotating at a uniform speed under the cooperation of the sleeve 204. That is, it rotates synchronously during the process of the dynamic pressure rod 201 reciprocating and sliding to push the raw material. Since the end of the dynamic pressure rod 201 is fixedly connected to the elliptical head 206, if it comes into direct contact with the agglomerated material during its rotation, it can effectively increase the breaking effect on the agglomerated material.

[0024] Specifically, the reciprocating assembly includes a connecting block 207 and a connecting component. The plurality of dynamic pressure rods 201 are rotatably connected to the connecting block 207, and the connecting block 207 is horizontally disposed on the outside of the horizontal tube 101.

[0025] The connecting component is used to slide and guide the connecting block 207.

[0026] Specifically, the connecting component includes a guide block 208, the end of which is rotatably connected to a connecting block 207, and the guide block 208 is provided with a through groove 209, in which a shaft 301 is provided through, and the diameter of the shaft 301 is smaller than the width of the through groove 209.

[0027] The drive assembly is used to reciprocate the shaft 301 in the through groove 209.

[0028] In the above embodiment, the user drives the shaft 301 to rotate in a circular motion through the drive assembly. During this process, the shaft reciprocates within the through groove 209, thereby driving the guide block 208 to perform linear reciprocating motion. Since the guide block 208 and the connecting block 207 are rotatably connected, the guide block 208 then pushes the connecting block 207, causing the multiple dynamic pressure rods 201 rotatably mounted on it to periodically insert between their corresponding static pressure rods 202, thereby pushing the raw material to break up.

[0029] For the above examples, those skilled in the art should know that the implementation of the above technical solutions is not limited to the specific shaft 301 described in the above embodiments. For example, the shaft 301 should be made of a wear-resistant material. The purpose of this arrangement is to avoid excessive wear.

[0030] Specifically, the drive assembly includes a disc 302, the top of the shaft 301 is rotatably connected to the eccentric part of the disc 302, and a guide rod 303 is fixedly connected to the center of the disc 302. The guide rod 303 is fixedly connected to the output shaft of the motor 304, and the motor 304 is vertically arranged outside the raw material conveying pipe 203.

[0031] For the above examples, those skilled in the art should know that when implementing the above technical solutions, it is not limited to the specific motor 304 described in the above embodiments. For example, the motor 304 should be a motor with a self-locking effect. The purpose of this setting is to prevent the output shaft from reversing if an external force is applied to it after it has stopped and entered the self-locking state.

[0032] In the above embodiment, the user starts the motor 304 before pouring the raw material into the raw material conveying pipe 203. At this time, the guide rod 303 fixedly connected to its output shaft starts to rotate, that is, the disc 302 fixedly connected to it starts to rotate at a constant speed. The shaft 301 rotatably connected to its eccentric part can rotate in a circle with its axis as the fulcrum, thereby pushing the through groove 209 to slide back and forth.

[0033] Specifically, the motor 304 is fixedly mounted on the motor mounting bracket 305, and the motor mounting bracket 305 is fixedly connected to the top of the raw material conveying pipe 203 near the pipe opening; by mounting the motor 304 on the motor mounting bracket 305, vibration during operation can be effectively avoided.

[0034] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0035] The term "fixed connection" as used in this application refers to a connection in which parts or components are fixed without any relative movement. This includes both detachable and non-detachable connections.

[0036] (1) Detachable connection: Components are fixed together using threaded sections, splines, wedges, etc. This type of connection can be disassembled during maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of bolts, keys, and wedges) and properly tightened.

[0037] (2) Non-removable connections: These mainly refer to welding, riveting, and tenon joints. Since disassembly requires forging, sawing, or oxyacetylene cutting for repair or replacement, the parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection, and remedial measures (such as correction and polishing) during connection.

[0038] The sliding connection referred to in this application means that the component can slide along a linear trajectory, and the hinge referred to in this application means that the component can rotate along an axial constraint.

[0039] In some cases, the sliding connection and hinge referred to in this application may also be damped, enabling the component to maintain in the desired position.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
