Description

Technical Field

[0001] The utility model relates to the technical field of sealant production, in particular to a quantitative feeding device used in sealant production. Background Art

[0002] Sealant refers to a sealing material that deforms with the shape of the sealing surface, is not easy to flow, and has a certain degree of adhesion. It is an adhesive used to fill the gap of the configuration to play a sealing role. It has the functions of leak prevention, waterproofing, vibration prevention, sound insulation, and heat insulation. It is usually made of dry or non-dry viscous materials such as asphalt, natural resin or synthetic resin, natural rubber or synthetic rubber as the base material, combined with inert fillers such as talcum powder, white clay, carbon black, titanium dioxide and asbestos, and then added with plasticizers, solvents, curing agents, accelerators, etc. It can be divided into three categories: elastic sealant, liquid sealing gasket and sealing putty. It is widely used in the sealing of construction, transportation, electronic instruments and parts.

[0003] During the production process of sealants, chemical raw materials are usually added into chemical equipment. The existing method of adding chemical raw materials is manual addition. This adding method not only increases the workload of the staff, but also the added amount is inaccurate, which easily affects the quality of the subsequent sealant and cannot achieve the effect of quantitative addition, resulting in poor quality of the products produced.

[0004] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0028] like Figures 1 to 7 As shown, the utility model is a quantitative feeding device for sealant production, comprising: a mixing box 1, a raw material box 7 fixedly installed on the top of the mixing box 1, a quantitative feeding mechanism for quantitatively feeding the sealant raw material, and a stirring mechanism for stirring the sealant raw material;

[0029] The quantitative feeding mechanism includes: a rotating shaft rotatably mounted on the side wall of the raw material box 7, a crushing roller 9 fixedly sleeved on the outer edge of the rotating shaft, the crushing roller 9 is located in the inner cavity of the raw material box 7, and a motor 8 drives the rotating shaft to rotate, the motor 8 is fixedly mounted on the side wall of the raw material box 7, a feeding pipe plugged into the top of the raw material box 7, a feeding pipe 11 plugged into the bottom of the raw material box 7, the bottom of the feeding pipe 11 extends to the inner cavity of the mixing box 1, and a linkage shaft rotatably mounted on the side wall of the feeding pipe 11, and one end of the linkage shaft passes through the side wall of the mixing box 1 and is rotatably connected to the side wall of the mixing box 1, and a feeding pipe fixedly sleeved on the outer edge of the linkage shaft Roller 12, the unloading roller 12 is composed of a cylinder, a groove opened on the outer edge of the cylinder, and a linkage component for linking the crushing roller 9 and the unloading roller 12; the linkage component includes: a rotating plate 13 fixedly sleeved on one side of the rotating shaft, a limit plate 15, the limit plate 15 is fixedly connected to the side close to the rotating plate 13, the limit plate 15 is composed of a circular plate, an inwardly concave arc groove opened on the side wall of the circular plate, a connecting rod 14 fixedly installed on one side of the rotating plate 13, and a linkage plate 16 fixedly sleeved on the outer edge of the linkage shaft. The linkage plate 16 is composed of a circular plate, a U-shaped groove opened on the side wall of the circular plate, and an inwardly concave arc groove.

[0030] The sealant raw material is added to the inner cavity of the raw material box 7 in advance through the feed pipe. When the inner cavity of the mixing box 1 needs to be fed, the motor 2 8 is started, and the motor 2 8 drives the rotating shaft to rotate, and the crushing roller 9, the rotating plate 13 and the limit plate 15 are driven to rotate through the rotating shaft. The raw material can be crushed by the rotation of the crushing roller 9 to avoid the agglomeration of the raw material, which causes the raw material to be blocked in the inner cavity of the raw material box 7 and affects the feeding problem;

[0031] The connecting rod 14 is driven to rotate by the rotating plate 13. When the connecting rod 14 rotates to the inner cavity of the U-shaped groove on the side wall of the linkage plate 16, the linkage plate 16 can be driven to rotate together, and the linkage shaft is driven to rotate by the linkage plate 16, and the unloading roller 12 is driven to rotate by the linkage shaft. When the linkage plate 16 rotates 90 degrees, the connecting rod 14 moves out of the inner cavity of the U-shaped groove, and at this time, it cannot drive the linkage plate 16 to rotate, so that the linkage plate 16 can be driven to rotate intermittently.

[0032] When the connecting rod 14 moves to the inner cavity of the U-shaped groove and drives the linkage plate 16 to rotate, the inwardly concave arc groove on the limiting plate 15 rotates toward the linkage plate 16. When the connecting rod 14 moves out of the inner cavity of the U-shaped groove, the outer side of the limiting plate 15 fits with the inner wall of the inwardly concave arc groove on the linkage plate 16, thereby limiting the linkage plate 16 and preventing the linkage plate 16 from rotating by itself, thereby controlling the rotation of the linkage plate 16.

[0033] During actual use, the raw materials in the inner cavity of the raw material box 7 fall into the inner cavity of the arc-shaped groove on the outer edge of the discharge roller 12 through the feeding tube 11, and move according to the movement of the arc-shaped groove. Since the intermittent rotation of the linkage plate 16 can drive the discharge roller 12 to rotate intermittently, the raw materials can be intermittently added to the inner cavity of the mixing box 1 through the rotation of the discharge roller 12, thereby avoiding the problem of uneven stirring caused by adding too much raw materials at one time. Since the amount of raw materials stored in the arc-shaped groove on the outer edge of the discharge roller 12 is fixed, automatic quantitative feeding of the inner cavity of the mixing box 1 can be achieved without manual addition, which saves time and effort, improves the accuracy of the added amount, and ensures the quality of the subsequent sealant.

[0034] In the above mechanism, the motor 2 8 is rotated to drive the crushing roller 9 to rotate continuously and the feeding roller 12 to rotate intermittently. On the one hand, the raw materials can be crushed to avoid agglomeration of the raw materials, which may cause the raw materials to be blocked in the inner cavity of the raw material box 7 and affect the feeding problem. On the other hand, the problem of uneven stirring caused by adding too much raw materials at one time can be avoided. Since the amount of raw materials stored in the arc groove on the outer edge of the feeding roller 12 is fixed, automatic quantitative feeding of the inner cavity of the mixing box 1 can be achieved without manual addition, which saves time and effort, improves the accuracy of the added amount, and ensures the quality of the subsequent sealant.

[0035] A second material guide plate 10 is symmetrically fixedly installed at the bottom of the inner cavity of the raw material box 7. The second material guide plate 10 can guide the sealant raw material to facilitate the sealant raw material to flow into the feeding pipe 11.

[0036] The stirring mechanism includes: a stirring shaft rotatably mounted on the top of the mixing box 1, a motor 2 driving the stirring shaft to rotate, the motor 2 fixedly mounted on the top of the mixing box 1, a stirring blade 3 fixedly mounted on the outer edge of the stirring shaft, and a spiral blade 4 fixedly sleeved on the outer edge of the stirring shaft;

[0037] When the sealant raw materials in the inner cavity of the mixing box 1 are stirred and mixed, the motor 2 is started, the motor 2 drives the rotating shaft to rotate, and the rotating shaft drives the stirring blade 3 and the spiral blade 4 to rotate. The sealant can be turned from bottom to top through the rotation of the spiral blade 4, so that the sealant can be stirred vertically, so that the sealant at the bottom and the top can be mixed, and then the sealant is stirred evenly, thereby improving the production quality of the sealant;

[0038] At the same time, the stirring blade 3 rotates to stir the sealant in a circumferential direction, thereby further improving the uniformity of the sealant and thus improving the production quality of the sealant.

[0039] In addition, when the motor 2 rotates in the reverse direction, the spiral blade 4 can drive the sealant to move from top to bottom, so that the sealant actively moves to the discharge pipe 6, thereby achieving the purpose of rapid discharge.

[0040] Through the above mechanism, the device can stir the sealant in the circumferential direction and in the longitudinal direction, thereby improving the uniformity of stirring and further improving the production quality of the sealant.

[0041] A guide plate 5 is fixedly installed at the bottom of the inner cavity of the mixing box 1, and a discharge pipe 6 is connected to the side wall of the guide plate 5 and the bottom of the mixing box 1, and a solenoid valve is installed on the outside of the discharge pipe 6; when the sealant is mixed, the solenoid valve is opened, and the sealant can be discharged through the discharge pipe 6. Through the setting of the guide plate 5, the sealant can be guided, so that the sealant can flow quickly into the discharge pipe 6, thereby accelerating the discharge efficiency.

[0042] The outer edge of the mixing box 1 is also fixedly mounted with supporting legs, and a plurality of supporting legs are evenly distributed in a ring shape on the outer edge of 1, thereby providing a stable support for the mixing box 1.

[0043] Working principle: When in use, the motor 2 8 rotates, thereby driving the crushing roller 9 to rotate continuously and the feeding roller 12 to rotate intermittently. On the one hand, the raw materials can be crushed to avoid agglomeration of the raw materials, which may cause the raw materials to be blocked in the inner cavity of the raw material box 7 and affect the feeding problem. On the other hand, it avoids the problem of uneven stirring caused by adding too much raw materials at one time. Since the amount of raw materials stored in the arc groove on the outer edge of the feeding roller 12 is fixed, automatic quantitative feeding of the inner cavity of the mixing box 1 can be achieved without manual addition, which saves time and effort, improves the accuracy of the addition amount, and ensures the quality of the subsequent sealant. After the sealant raw material enters the inner cavity of the mixing box 1, the motor 2 is started to drive the stirring blade 3 and the spiral blade 4 to rotate, so that the sealant can be stirred and mixed, and the mixed sealant is discharged through the discharge pipe 6.
