Description

Technical Field

[0001] The utility model relates to the technical field of suction machines, in particular to a material suction device. Background Art

[0002] The vacuum suction machine is a vacuum conveying equipment for powdered materials and powder-granular mixtures. It can be loaded with powdered materials, plastic granules, powder-granular mixtures, crushers, injection molding machines, and can also be used for the transportation and loading of powdered and granular materials in the production process of medicine and chemical industry. The working principle of the vacuum suction machine is to use a vortex air pump to draw air so that the inlet of the suction nozzle and the entire system are in a vacuum state. The powdered and granular materials are sucked into the nozzle along with the outside air to form a material airflow, which reaches the hopper through the suction pipe, and the gas and material are separated in the hopper. The separated materials enter the receiving equipment.

[0003] In order to ensure the normal operation of the suction function, a certain amount of outside air must be able to enter the suction pipe during the suction process. Therefore, the suction pipe of the suction machine cannot be inserted too deeply into the material. At present, when sucking materials, workers generally hold the suction pipe to control the insertion depth, which not only increases the company's worker costs, but also increases the labor intensity of the workers. Utility Model Content

[0004] The utility model aims to solve the shortcomings of the prior art that a certain amount of outside air needs to be ensured to enter the suction pipe during the suction process, and that hand-held operation is relatively laborious, and thus a material suction device is proposed.

[0007] A sliding sleeve is fixedly installed on the sliding seat with an axis vertically arranged, the hard tube body passes through the sliding sleeve and the two are slidably connected, a lightweight sphere passes through and is fixedly installed at the lower part of the hard tube body, and the bottom end of the hard tube body is at least partially located outside the lightweight sphere.

[0008] A fixing plate is fixedly mounted on the lightweight sphere, a pull rod is passed through the fixing plate and is slidably connected thereto, one end of the pull rod is fixedly connected to a clamping plate, a thrust spring is connected between the other end of the pull rod and the fixing plate, and the hard tube body is clamped between the clamping plate and the fixing plate.

[0009] The light sphere is a foam sphere or a hollow plastic sphere.

[0014] The horizontal cross-section of the material storage cavity of the material storage box is a fan-shaped structure, and the center of the fan-shaped structure is located on the axis of the supporting shaft.

[0015] The utility model proposes a material suction device, which has the beneficial effect that the hard tube body of the device can move back and forth in a horizontal plane, and at the same time, the hard tube body of the device can move downward as the material is reduced.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-3A material suction device comprises a support seat 1, on which a vertically arranged support shaft 12 is rotatably connected, a second rotating motor 13 is transmission-connected below the support shaft 12, a horizontal guide rod 7 is fixedly installed above the support shaft 12 and rotatably connected to a horizontally arranged threaded rod 8, the threaded rod 8 is transmission-connected to a first rotating motor 11, the threaded rod 8 is threadedly connected to a slide seat 9, the slide seat 9 is slidably connected to the guide rod 7, a hard tube body 10 is provided on the slide seat 9 and can move downward as the material is reduced, the top end of the hard tube body 10 is connected to a suction pipe of a suction machine, and suction is generated by the suction pipe in the hard tube body 10 to achieve material suction.

[0022] When the device is working, the material to be sucked is placed under the hard tube body 10. During the suction process, the second rotating motor 13 drives the supporting shaft 12 to rotate by the forward and reverse reciprocating motion, so that the hard tube body 10 is translated forward or reversely around the axis of the supporting shaft 12. At the same time, the first rotating motor 11 drives the threaded rod 8 to rotate forward and reversely reciprocatingly, so that the hard tube body 10 is close to the supporting shaft 12 or away from the supporting shaft 12, thereby realizing the translational reciprocating motion of the hard tube body 10 in the horizontal plane. At the same time, the hard tube body 10 of the device can move downward as the material is reduced. Under the joint action of horizontal translation and downward movement, the material can be sucked, and the action of manually holding the suction pipe is replaced by the machine structure.

[0023] refer to Figure 1 As an implementation method in which the hard tube body 10 moves downward as the material decreases, a sliding sleeve 6 with a vertical axis is fixedly installed on the slide seat 9, the hard tube body 10 passes through the sliding sleeve 6 and the two are slidably connected, and a lightweight sphere 5 passes through and is fixedly installed on the lower part of the hard tube body 10. The bottom end of the hard tube body 10 is at least partially located outside the lightweight sphere 5. The diameter of the lightweight sphere is much larger than the diameter of the material, so the lightweight sphere will not sink into the material. When the hard tube body 10 swings, the lightweight sphere will move up and down following the uneven height of the material, and will drive the hard tube body to move downward as the material decreases, thereby realizing adaptive adjustment of the up and down movement of the hard tube body 10.

[0024] refer to Figure 1 , Figure 3 A fixing plate 17 is fixedly installed on the lightweight sphere 5, and a pull rod 19 is passed through and slidably connected to the fixing plate 17. One end of the pull rod 19 is fixedly connected to the clamping plate 16, and a thrust spring 18 is connected between the other end of the pull rod 19 and the fixing plate 17. The hard tube body 10 is clamped between the clamping plate 16 and the fixing plate 17. The pull rod is driven by the thrust spring 18 to pull the clamping plate 16 toward the fixing plate 17, so that the hard tube body 10 is clamped between the clamping plate 16 and the fixing plate 17, so that the relative position of the hard tube body 10 and the lightweight sphere 5 is fixed.

[0025] The light sphere 5 is a foam sphere or a hollow plastic sphere, which is light and not easy to sink into the material.

[0026] The bottom of the support base 1 is supported on the ground by a plurality of roller legs 14, so as to facilitate the movement of the entire device.

[0027] A vibration support platform is provided above the support seat 1 and below the hard pipe body 10; the vibration support platform includes a support plate 4, which is supported on the support seat 1 through a plurality of elastic supports 3, and a vibration motor 2 is installed on the support plate 4; the suction device includes a storage box 15, and the storage box 15 is fixed on the support plate 4. The material is poured into the storage box 15, and the support plate 4 is used to drive the storage box 15 to vibrate by the vibration motor 2, so that the material inside the storage box 15 is evenly distributed on the horizontal plane.

[0028] refer to Figure 2 The horizontal cross-section of the storage cavity of the storage box 15 is a fan-shaped structure, and the center of the fan-shaped structure is located on the axis of the support shaft 12. The fan-shaped storage box 15 can better adapt to the movement trajectory of the hard tube body, so that the support shaft 12 can better set the rotation angle.

[0029] The above is only a preferred specific implementation method of the utility model, but the protection scope of the utility model is not limited thereto. Any technical solution, concept, and design obtained by equivalent replacement or change based on the technical solution and utility model concept of the utility model by any technician familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model.
