Description

Technical Field

[0001] This utility model relates to the field of sealing agent mixing technology, and in particular to a sealing agent mixing device. Background Technology

[0002] When cracks, holes, or grooves appear in buildings or floors, mix water, cement, and sealant to form a grout, and fill the holes or cracks with it. After the sealant has completely dried (generally 24 hours), water it to cure, ensuring the substrate is completely moist. A water tightness test can be conducted before the coating dries to check the sealing effect and whether the coating thickness meets the requirements.

[0003] The mixing ratio of sealant to water is generally 2:1 or 3:1. Pour an appropriate amount of sealant into a mixer, and slowly add water while stirring. After thorough mixing, let it stand for about 15 minutes before use. Since sealant is mostly used on-site or outdoors, operators typically use electric mixers or manual mixing rods. However, because both electric and manual mixers are handheld, they not only increase labor output due to long working hours, but also rely on the operator's experience or subjective judgment to measure whether the mixture is sufficiently mixed, easily leading to uneven mixing of the sealant.

[0004] If the sealant is not mixed evenly, the chemical components may not react fully, thus prolonging the setting time and hindering the need for rapid on-site operations. More importantly, uneven mixing can also lead to uneven distribution of moisture and chemical components in the sealant, resulting in a lack of strength in the cured material, making it prone to powdering and causing the sealant to fail, thus wasting raw materials. Utility Model Content

[0005] In view of this, the present invention aims to provide a mixing device for a sealant, which can fully stir the sealant raw materials, improve the uniformity of the sealant, and thus ensure the sealing effect on cracks or holes.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A mixing device for a sealant includes a mixing chamber having a cavity, a pivot portion pivotally connected to the mixing chamber, and a drive portion for driving the pivot portion to rotate.

[0008] The pivot part is provided with a bevel gear and at least one bushing that meshes with the bevel gear for transmission.

[0009] One end of the bushing is provided with a toothed portion that meshes with the bevel gear, and the other end of the bushing is connected to a stirring assembly;

[0010] The pivot portion extends along the width direction of the mixing box;

[0011] When the driving part drives the pivot part to rotate, the bushing rotates along the axis of the pivot part while simultaneously meshing with the bevel gear.

[0012] Furthermore, the pivoting part includes a support shaft pivotally connected to the mixing tank, and a plurality of through shafts arranged radially along the support shaft, with the bushings sleeved on the through shafts.

[0013] Furthermore, the mixing device also includes a fixing member, through which the support shaft and the through shaft pass;

[0014] A deep groove ball bearing is provided between the support shaft and the fixing member, and / or a deep groove ball bearing is provided between the through shaft and the bushing.

[0015] Furthermore, a deep groove ball bearing is provided between the bushing and the fixing member.

[0016] Furthermore, the stirring assembly includes a sleeve screwed to the outside of the bushing, a fixed post connected to one end of the sleeve, and stirring blades evenly distributed on the fixed post along the radial circumference.

[0017] The sleeve has a threaded hole formed inside it to match the bushing.

[0018] Furthermore, the four stirring blades are located on the outside of the fixed column;

[0019] Each pair of stirring blades is arranged in a straight line opposite to each other.

[0020] Furthermore, one of the stirring blades includes a first inclined section that slopes upwards;

[0021] The adjacent stirring blade includes a second inclined section that slopes downwards;

[0022] Along the height direction of the fixed column, the first inclined segment and the second inclined segment partially overlap.

[0023] Furthermore, the fixing post is provided with a through mounting hole, the through shaft is provided with a guide hole corresponding to the mounting hole, and the fixing post is provided with a guide post that passes through the mounting hole and enters the guide hole.

[0024] Furthermore, the power output end of the drive unit is provided with a drive pulley, and one end of the support shaft is provided with a driven pulley. The drive pulley and the driven pulley are connected by a belt drive.

[0025] Furthermore, the mixing chamber includes a lower housing and a cover that is fastened to the lower housing;

[0026] The lower housing is provided with an annular sealing ring, which is snapped into the connection between the lower housing and the cover.

[0027] Compared with the prior art, this utility model has the following advantages:

[0028] The sealing agent mixing device of this utility model, by setting a driving part to drive the pivot part to rotate, drives the bushing to rotate along the axial direction of the pivot part. At the same time, the bushing meshes with the bevel gear and rotates, so that the stirring component located at the other end of the bushing can rotate in two directions simultaneously in the mixing box. The pivot part stirs in the longitudinal section of the mixing box to form a longitudinal stirring flow. The stirring component rotates perpendicular to the pivot part and forms an interlaced stirring flow with the pivot part, which increases the fluidity of the liquid in different directions, improves the friction of the liquid molecules, and thus ensures the mixing effect of the sealing agent.

[0029] In addition, by setting a fixing member and connecting the fixing member to the mixing box through the support shaft, the structural strength of the pivot and stirring assembly is increased, and the meshing part of the bevel gear and the bushing is protected from being stuck by the sealing agent material, ensuring the effective movement of the stirring assembly and improving the smoothness of the use of the mixing device.

[0030] Furthermore, by installing deep groove ball bearings between the support shaft and the fixed component, and / or between the through shaft and the bushing, the rotational flexibility of the support shaft and bushing is increased, further ensuring the effective movement of the mixing assembly. Additionally, by using a sleeve to screw the mixing assembly onto the bushing, installation, disassembly, and replacement are facilitated, improving the convenience and adaptability of the mixing device.

[0052] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0053] This embodiment relates to a mixing device for a sealing agent, which, as a whole, is as follows: Figures 1 to 6 As shown, the mixing device for the sealant includes a mixing chamber 1 with a cavity, a pivot part 2 pivotally connected to the mixing chamber 1, and a drive part 3 for driving the pivot part 2 to rotate. The pivot part 2 is provided with a bevel gear 4 and at least one bushing 5 that meshes with the bevel gear 4. One end of the bushing 5 has a toothed portion 501 that meshes with the bevel gear 4, and the other end of the bushing 5 is connected to a stirring assembly 6. The pivot part 2 extends along the width direction of the mixing chamber 1. When the drive part 3 drives the pivot part 2 to rotate, the bushing 5 rotates along the axis of the pivot part 2 while simultaneously meshing and rotating with the bevel gear 4.

[0054] The sealing agent mixing device of this embodiment uses a drive unit 3 to drive the pivot unit 2 to rotate, thereby driving the bushing 5 to rotate along the axial direction of the pivot unit 2. At the same time, the bushing 5 meshes with the bevel gear and rotates, so that the stirring assembly 6 located at the other end of the bushing 5 can rotate in two directions simultaneously in the mixing tank 1. The pivot unit 2 stirs in the longitudinal section of the mixing tank 1, forming a longitudinal stirring flow. The stirring assembly 6 rotates perpendicular to the pivot unit 2 due to meshing with the bevel gear 4, forming an interlaced stirring flow with the pivot unit 2, increasing the fluidity of the liquid in different directions, improving the friction of the liquid molecules, and thus ensuring the mixing effect of the sealing agent.

[0055] Based on the above overall description, an exemplary structure of the sealing agent mixing device in this embodiment is as follows: Figures 1 to 2 As shown, the mixing box 1 is formed into a rectangular box structure. Preferably, the mixing box 1 includes a lower shell 101 and a cover 102 that is fastened to the lower shell 101. The lower shell 101 is provided with an annular sealing ring 103, which is snapped into the connection between the lower shell 101 and the cover 102. Furthermore, for ease of carrying and movement, handles 104 are provided on both the cover 102 and the lower shell 101, making it suitable for outdoor use.

[0056] Furthermore, such as Figures 1 to 4As shown, the power output end of the drive unit 3 is provided with a drive pulley, and one end of the support shaft 201 is provided with a driven pulley. The drive pulley and the driven pulley are driven by a belt.

[0057] As a preferred embodiment, such as Figures 2 to 3 As shown, the pivoting part 2 includes a support shaft 201 pivotally connected to the mixing tank 1, and several through shafts 202 arranged radially along the support shaft 201, with bushings 5 ​​fitted onto the through shafts 202. In this embodiment, four through shafts 202 are arranged radially along the support shaft 201 and integrally formed. This arrangement increases the structural strength of the pivoting part 2, which is beneficial for maintaining the stirring force of the sealing agent and ensuring the stirring effect.

[0058] In addition, such as Figure 3 and Figure 6 As shown, the diameter of the support shaft 201 is larger than the diameter of the through shaft 202, and the through shaft 202 can be fixed by welding it to the support shaft 201. The bevel gear 4 is a cylindrical flange sleeved on the support shaft 201. One end of the bevel gear 4 is provided with a mounting hole 6021 and is fixed to the side wall of the cavity of the mixing box 1 by screws. The other end has serrations that mesh with the toothed part 501.

[0059] Among them, the bevel gear 4 is connected to the pivot key via a flat key.

[0060] Still Figure 3 and Figure 6 As shown, a connecting seat 8 is fitted onto the other end of the support shaft 201. The connecting seat 8 is fixed to the lower housing 101 by bolts, and a deep groove ball bearing is provided between the connecting seat 8 and the support shaft 201. This arrangement can effectively support the pivot part 2, ensure the perpendicularity of the support shaft 201 to the lower housing 101, and allow the pivot part 2 to stir along the longitudinal section of the mixing box 1 when it rotates, thus avoiding interference with the mixing box 1.

[0061] Furthermore, such as Figures 2 to 6 As shown, the mixing device also includes a fixing member 7, through which the support shaft 201 and the through shaft 202 pass. A deep groove ball bearing is provided between the support shaft 201 and the fixing member 7, and a deep groove ball bearing is also provided between the through shaft 202 and the bushing 5. In other embodiments, the deep groove ball bearing can be replaced with a bearing housing or a self-lubricating bearing. In this embodiment, the fixing member 7 adopts a rectangular housing with a rectangular cavity inside, and the meshing parts of the bushing 5 and the bevel gear 4 are both located in the cavity of the fixing member 7.

[0062] As mentioned above, by setting the fixing member 7 and connecting it to the mixing box 1 via the support shaft 201, the structural strength of the pivot part 2 and the stirring assembly 6 is increased. This also protects the meshing part between the bevel gear 4 and the bushing 5 from being stuck by the sealing agent material, ensuring the effective movement of the stirring assembly 6 and improving the smoothness of the mixing device. Furthermore, by installing deep groove ball bearings between the support shaft 201 and the fixing member 7, and between the through shaft 202 and the bushing 5, the rotational flexibility of the support shaft 201 and the bushing 5 is increased, further ensuring the effective movement of the stirring assembly 6.

[0063] In addition, such as Figures 2 to 6 As shown, in order to increase the movement flexibility of the bushing 5, a deep groove ball bearing is provided between the bushing 5 and the fixing member 7 to ensure the stirring flexibility of the stirring assembly 6.

[0064] Preferably, such as Figure 7 As shown, the stirring assembly 6 includes a sleeve 601 screwed to the outside of the bushing 5, a fixing post 602 connected to one end of the sleeve 601, and stirring blades 603 evenly distributed on the fixing post 602 along the radial circumference. The sleeve 601 has a threaded hole that matches the bushing 5. By setting the sleeve 601 to screw the stirring assembly 6 onto the bushing 5, it is easy to install, disassemble and replace, thus improving the convenience and adaptability of the mixing device.

[0065] Furthermore, still as Figure 7 As shown, four stirring blades 603 are located on the outside of the fixed column 602, with each pair of stirring blades 603 arranged in a straight line facing each other. Arranging the two stirring blades 603 in a straight line facing each other increases the stirring intensity perpendicular to the shaft sleeve 5, facilitating the formation of a liquid stirring flow. While the four stirring blades 603 rotate along the support shaft 201, they simultaneously stir the raw materials at each position in real time, ensuring effective mixing of the raw materials at the bottom and top, improving stirring efficiency, and guaranteeing the mixing effect.

[0066] In addition, such as Figure 7 As shown, one of its stirring blades 603 includes a first inclined section 6031 that slopes upwards, and an adjacent stirring blade 603 includes a second inclined section 6032 that slopes downwards. Along the height direction of the fixed column 602, the first inclined section 6031 and the second inclined section 6032 partially overlap. By setting the first inclined section 6031 and the second inclined section 6032 with different inclination directions, stirring at different positions can be achieved during the stirring process, increasing the stirring area and improving the stirring effect.

[0067] In addition, such as Figure 7 and Figure 8As shown, the fixed column 602 has a through mounting hole 6021, the through shaft 202 has a guide hole 2021 corresponding to the mounting hole 6021, and the fixed column 602 has a guide column 604 that passes through the mounting hole 6021 and enters the guide hole 2021. In this embodiment, the guide column 604 is bolted and fixed to the fixed column 602. By setting the guide column 604, the vibration of the stirring part due to bearing clearance during the stirring process can be avoided, the operating stability of the device can be improved, and the bearing damage caused by excessive resistance due to the viscosity of the raw materials can be avoided.

[0068] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
