Description

Technical Field

[0001] The utility model relates to a vibrating feeding and packaging scale, belonging to the field of packaging equipment. Background Art

[0002] Vibrating packaging scales are mainly used for filling and conveying powder materials. Powder materials have a stronger viscosity than themselves and are prone to agglomeration and adhesion during the process. When the vibration amplitude is low, the viscosity between the powder material and the pipe wall and between the powder materials themselves will affect the normal filling and conveying efficiency. This situation will not only affect the operating efficiency but also the accuracy of the packaging scale's material filling. Utility Model Content

[0003] The technical problem to be solved by the utility model is to overcome the technical problems in the prior art and provide a vibrating feeding and packaging scale.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] The vibrating feeding packaging scale includes a feed hopper, which is fixedly connected to a frame, a connecting pipe in a floating connection with the feed hopper, a discharger connected to the connecting pipe, a vibration excitation pipe connected to the connecting pipe, a vibration excitation motor fixed to the vibration excitation pipe, a discharge pipe in a floating connection with the discharge pipe, and a fixed connection with the frame;

[0006] A vibration transmission mechanism is connected to the excitation tube. The vibration transmission mechanism includes a plurality of swing arms rotatably connected to the radial top inner wall of the excitation tube. The rotation axis of the swing arm is arranged perpendicular to the axis of the excitation tube. A counterweight is connected to one end of the swing arm. The counterweights on adjacent swing arms are arranged in opposite positions.

[0007] A material discharging mechanism is provided in the discharge pipe, and the material discharging mechanism includes a plurality of driven arms rotatably connected to the inner wall of the radial top of the discharge pipe, and a plurality of splines are arranged in an array on the driven arms, and the splines extend toward the radial bottom of the discharge pipe;

[0008] The end of the swing arm and the end of the driven arm are movably connected via an elastic connecting piece.

[0009] As a further improvement of the present invention, the discharge pipe and the excitation pipe are connected by an elastic support ring, and the elastic support ring includes a connecting ring and an elastic ring, wherein the two ends of the connecting ring are in contact with the inner walls of the discharge pipe and the excitation pipe respectively, and the elastic ring is integrally arranged on the outer side wall of the connecting ring, and the elastic ring is embedded between the ends of the discharge pipe and the excitation pipe, and a deformation cavity with an annular hollow structure is provided in the elastic ring; the elastic support ring not only provides elastic floating support, but also compared with the spring tube with a wave structure, this structure will not bring additional flow resistance to the material while ensuring good elastic support, and will not cause local accumulation of material.

[0010] As a further improvement of the present invention, the excitation tube and the connecting tube are connected by a vibration-stop ring, which is made of nylon material. An annular inlay groove is provided at each end of the vibration-stop ring, and the end of the excitation tube and the end of the connecting tube are embedded in the inlay groove. The vibration-stop ring is made of relatively hard nylon, because the excitation tube needs to vibrate reciprocatingly, and the stress will be concentrated at the bend of the connecting tube that is bent down from the feed hopper. If the excitation tube is rigidly connected to the connecting tube, it is easy to cause the bend of the connecting tube to rupture. If a flexible connection is used, it is easy to cause the entire connecting tube part to lack effective structural support and fall, thereby affecting the life of the elastic connector.

[0011] As a further improvement of the present invention, a material baffle is arranged between the anti-vibration ring and the elastic ring, a material baffle sheet is arranged at the radial upper half of the anti-vibration ring, a first connecting groove parallel to the axial direction of the anti-vibration ring and an integral structure with the material baffle sheet is also arranged in the anti-vibration ring, a second connecting groove parallel to the axial direction of the elastic ring is arranged at the radial upper half of the elastic ring, the material baffle is made of elastic material, and the two ends of the material baffle are respectively embedded in the first connecting groove and the second connecting groove; the two ends of the material baffle are connected to the anti-vibration ring and the elastic ring that participate in the shock absorbing function, and the material baffle can not only reduce the powder material coming down from the feed hopper from affecting the normal operation of the swing arm.

[0012] As a further improvement of the present invention, the elastic connecting member is a long strip of connecting spring, the two ends of which are fixedly connected to the ends of the swing arm and the driven arm by bolts; the connecting spring has good tensile strength and can effectively transmit the swing torque.

[0013] As a further improvement of the present invention, a first swing rod is fixed through the excitation tube, a first swing ring is integrally provided in the middle of the swing arm, the swing arm is connected to the first swing rod through the first swing ring, and a first sliding washer connected to the first swing rod is also provided between adjacent swing arms; through the unified swing rod connection, the structure is simpler and more stable, and does not require complicated processing and assembly.

DETAILED DESCRIPTION

[0022] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0023] like Figure 1 , a vibrating feeding packaging scale includes a feed hopper 23 fixed on the top of the frame, and an arc-shaped connecting pipe 21 is connected to the bottom of the feed hopper 23 through a spring tube 22. A discharger is connected to the connecting pipe 21, and the discharger includes an excitation tube 1 and a discharge tube 5, wherein one end of the excitation tube 1 is connected to the connecting pipe 21 through a vibration-proof ring 13, and the vibration-proof ring 13 is made of nylon material. An annular inlay groove 14 is respectively provided at both ends of the vibration-proof ring 13, and the end of the excitation tube 1 and the end of the connecting pipe 21 are embedded in the inlay groove 14. An excitation motor 20 is fixed on the excitation tube 1 through a motor seat 19. The excitation motor 20 is used to drive the excitation tube 1 to vibrate, and the end of the excitation tube 1 is connected to the discharge tube 5 through an elastic support ring, and the discharge tube 5 is fixed to the frame.

[0024] Among them, Figure 2 and Figure 3A vibration transmission mechanism is connected inside the excitation tube 1, and the vibration transmission mechanism includes a plurality of swing arms 3 rotatably connected to the radial top inner wall of the excitation tube 1. The rotation axis of the swing arm 3 is arranged perpendicular to the axis of the excitation tube 1. A first swing rod 2 is fixed through the excitation tube 1, and a first swing ring is integrally provided in the middle of the swing arm 3. The swing arm 3 is connected to the first swing rod 2 through the first swing ring. A first sliding washer 24 connected to the first swing rod 2 is also provided between adjacent swing arms 3. A counterweight 4 is connected to one end of the swing arm 3, and the counterweights 4 on adjacent swing arms 3 are arranged in opposite positions.

[0025] Among them, such as Figure 2 and Figure 3 A material discharging mechanism is provided in the discharge pipe 5, and the material discharging mechanism includes a plurality of driven arms 7 rotatably connected to the inner wall of the radial top of the discharge pipe 5. A second swing rod 6 is fixed through the discharge pipe 5. A second swing ring is integrally provided at the middle part of the driven arm 7. The driven arm 7 is connected to the second swing rod 6 through the second swing ring. A second sliding washer 25 connected to the second swing rod 6 is also provided between adjacent driven arms 7. A plurality of splines 8 are arranged in an array on the driven arm 7, and the splines 8 extend toward the radial bottom of the discharge pipe 5.

[0026] Among them, such as Figure 2 and Figure 3 The end of the swing arm 3 and the end of the driven arm 7 are movably connected through a connecting spring 11, and the two ends of the connecting spring 11 are fixedly connected to the ends of the swing arm 3 and the driven arm 7 through bolts 12.

[0027] Among them, such as Figure 2 The elastic support ring includes a connecting ring 9 and an elastic ring 10, wherein the two ends of the connecting ring 9 are in contact with the inner walls of the discharge pipe 5 and the excitation tube 1 respectively, and the elastic ring 10 is integrally arranged on the outer wall of the connecting ring 9. The elastic ring 10 is embedded between the ends of the discharge pipe 5 and the excitation tube 1, and a deformation cavity with an annular hollow structure is provided in the elastic ring 10.

[0028] Among them, such as Figure 2 A baffle plate 18 is provided between the anti-vibration ring 13 and the elastic ring 10, a baffle piece 15 is provided at the radial upper half of the anti-vibration ring 13, and a first connecting groove 16 parallel to the axial direction of the anti-vibration ring 13 and an integral structure with the baffle piece 15 is also provided in the anti-vibration ring 13, a second connecting groove 17 parallel to the axial direction of the elastic ring 10 is provided at the radial upper half of the elastic ring 10, the baffle plate 18 is made of elastic material, and the two ends of the baffle plate 18 are respectively embedded in the first connecting groove 16 and the second connecting groove 17.

[0029] During use, first, the feed hopper 23 is located on the top of the frame, and the exciting tube 1 vibrates under the drive of the exciting motor 20, and the connecting tube 21 also vibrates synchronously. The material is put into the feed hopper 23, and after passing through the spring tube 22, it enters the connecting tube 21 with a bent structure. Then, under the vibration of the connecting tube 21, the material moves toward the exciting tube 1. Because the movement of the material in the connecting tube 21 mainly depends on the gravitational potential energy and excitation, the probability of blockage is relatively low, but agglomeration also mainly occurs in the connecting tube 21, and the exciting force at the position of the exciting tube 1 is relatively large, and it is not easy to get blocked. However, the agglomerated material will be partially broken under the drive of the exciting tube 1 and then discharged. The material is transported in the pipe 5. Since the discharge pipe 5 is mainly used for outputting the material at the end, it is generally fixed to the frame in the prior art. The static discharge pipe 5 is prone to material accumulation and blockage. During the reciprocating vibration of the exciting tube 1, the counterweight 4 will float back and forth, thereby driving the swing arm 3 to swing. During the swinging of the swing arm 3, the driven wall is driven to swing through the connecting spring 11, and the spline 8 on the driven wall is inserted into the material, so that the agglomerated and accumulated materials are broken, and the material is pushed by the extrusion of the spline 8, which is similar to a shoveling action, so that the material overcomes the friction and moves relative to the wall of the discharge pipe 5, reducing the possibility of material blockage.

[0030] Moreover, during the reciprocating movement and vibration transmission of the slotting teeth 8, the agglomerated materials can be broken up, thereby preventing the materials from being discharged from the discharge pipe 5 in agglomerates and affecting the accuracy of weighing.

[0031] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
