Description

Technical Field

[0001] This utility model relates to the field of mixing technology for the production of water-resistant putty, and more specifically, it relates to a twin-shaft spiral mixing device for the production of water-resistant putty. Background Technology

[0002] In the field of building decoration, putty is an indispensable base treatment material used to fill defects in the wall substrate, providing a smooth and even base for subsequent paint application. Water-resistant putty, in particular, is widely used in damp environments such as kitchens, bathrooms, and basements, as well as in situations requiring high external durability, due to its excellent resistance to water vapor and moisture. The production process of water-resistant putty requires a mixing device, currently often using a twin-shaft spiral mixer. However, existing twin-shaft spiral mixers suffer from wear and tear on the spiral blades after prolonged use. The spiral blades and mixing shaft are integrated, making individual replacement inconvenient and costly. Furthermore, replacement requires complete disassembly of the top cover, which involves multiple bolts, resulting in low efficiency and compromising safety during subsequent use. A suitable locking mechanism for the cover is lacking, and the spiral blades exhibit poor stability after installation, also lacking a suitable reinforced locking mechanism. Utility Model Content

[0004] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a dual-shaft spiral mixing device for producing water-resistant putty, comprising a housing, with legs at each of the four corners of the lower end face of the housing, a detachable cover plate on the upper end face of the housing, a feed funnel penetrating the front side of the upper end face of the cover plate, a discharge pipe penetrating the front side of the lower end face of the housing, a rotating shaft rotatably mounted on the cover plate, two symmetrically arranged rotating shafts, a driving mechanism corresponding to the two rotating shafts on the upper end face of the cover plate, detachable mounting sleeves on both rotating shafts, spiral blades on the outer end face of both mounting sleeves, a rotating groove corresponding to the two rotating shafts on the inner wall of the bottom end of the housing, a symmetrically arranged clamping plate on each of the two rotating shafts, and a symmetrically arranged clamping groove on the inner wall of each of the two mounting sleeves corresponding to the clamping plate.

[0005] The present invention is further configured such that the driving mechanism includes a driving shaft and a driving motor, the driving shaft is rotatably mounted on the upper end of the cover plate, the driving motor is connected to the upper end of the driving shaft, a first gear is provided on the driving shaft, and a second gear is provided on each of the two rotating shafts corresponding to the first gear, the first gear and the second gear are meshed to realize rotational driving.

[0006] The present invention is further configured such that positioning rods are symmetrically provided on both the front and rear sides of the upper end of the box body, and positioning holes are provided on the cover plate corresponding to the multiple positioning rods to facilitate installation and positioning.

[0007] The present invention is further configured such that guide rods are symmetrically provided at both the left and right ends of the box body, and L-shaped plates are slidably provided on the two guide rods on the same side. Grooves are provided at both the left and right ends of the cover plate corresponding to the L-shaped plates to lock the cover plate.

[0008] The present invention is further configured such that adjusting rods are rotatably provided at both the left and right ends of the housing, and adjusting holes are provided on both L-shaped plates corresponding to the adjusting rods.

[0009] The present invention is further configured such that each of the two mounting sleeves has a first through hole, and each of the two rotating shafts has a second through hole corresponding to the first through hole. A retaining rod is detachably provided between the first through hole and the second through hole for easy reinforcement during installation.

[0010] The present invention is further configured such that each of the two clamping rods is provided with a retaining ring, and the retaining ring and the clamping rod are threaded together to achieve enhanced installation and locking.

[0011] (III) Beneficial Effects Compared with the prior art, this utility model provides a twin-shaft spiral mixing device for the production of water-resistant putty, which has the following beneficial effects: 1. The mounting sleeve design, through the interlocking structure of the clamping plate and slot, allows the mounting sleeve and spiral blades to be quickly disassembled and replaced as an independent module from the rotating shaft, eliminating the need to replace expensive drive components. This significantly reduces equipment maintenance costs and downtime. When the stirring blades wear or are damaged, only the worn parts need to be replaced, significantly improving the maintainability and economy of the equipment.

[0012] 2. Through the design of the cover plate, initial alignment is achieved by the cooperation of the positioning rod and the positioning hole. Then, the L-shaped plate is locked with the groove by adjusting the motor. This structure enables the cover plate to be installed quickly and accurately and sealed tightly. It simplifies the process of opening the cover for cleaning or maintenance and improves operational efficiency.

[0013] 3. Through the design of the locking rod, after the main body is installed through the locking groove, the locking rod, which passes through the first and second through holes, and is supplemented by a retaining ring, is threadedly locked, providing double fastening protection for the mounting sleeve. This reinforced locking structure effectively prevents the mounting sleeve from loosening or swaying under high-speed, high-load stirring conditions, greatly improving the rigidity and reliability of the transmission connection, and ensuring the stability of the stirring process and production safety.

A clamping groove 11 is symmetrically opened on the inner wall of the two mounting sleeves 7 corresponding to the clamping plate 10.

[0020] In this embodiment, the raw materials for the production of water-resistant putty are added into the box 1 through the feeding funnel 4. After the addition is completed, the drive mechanism is started. The drive mechanism drives the rotating shafts 6 on both sides to rotate synchronously. The rotating shafts 6 drive the mounting sleeve 7 with spiral blades 8 on the outside to rotate as a whole, realizing dual-shaft spiral mixing. After the mixing is completed, the valve on the discharge pipe 5 is opened to discharge the material.

[0021] More specifically, after prolonged use, the spiral blades 8 are severely worn. To replace the spiral blades 8, the cover plate 3 is completely disassembled, and the mounting sleeve 7 is removed relative to the rotating shaft 6. The new mounting sleeve 7 is installed corresponding to the rotating shaft 6. The clamping plate 10 and the clamping groove 11 are used for guidance during installation. After the entire installation is completed, the cover plate 3 is installed corresponding to the housing 1, and the rotating shaft 6 is inserted into the bottom rotating groove 9, which facilitates the individual replacement of the mounting sleeve 7 with the spiral blades 8.

[0022] Please see Figure 1 , Figure 2 and Figure 4 As one embodiment of the stirring drive: the drive mechanism includes a drive shaft 12 and a drive motor 13. The drive shaft 12 is rotatably mounted on the upper end of the cover plate 3. The drive motor 13 is connected to the upper end of the drive shaft 12. A first gear 14 is provided on the drive shaft 12. A second gear 15 is provided on each of the two rotating shafts 6 corresponding to the first gear 14. The first gear 14 and the second gear 15 are meshed.

[0023] Specifically, the control device has its own control system. When the drive motor 13 is started, the drive motor 13 is fixedly installed on the cover plate 3 through its own connecting plate. The drive motor 13 drives the drive shaft 12 to rotate. The first gear 14 on the drive shaft 12 and the second gear 15 on the two rotating shafts 6 mesh with each other to achieve synchronous rotation on both sides.

[0024] Please see Figures 1-3 and Figure 6 As one embodiment of the cover plate 3: positioning rods 16 are symmetrically provided on both the front and rear sides of the upper end of the box body 1. Positioning holes 17 are provided on the cover plate 3 corresponding to the multiple positioning rods 16. Guide rods 18 are symmetrically provided on both the left and right ends of the box body 1. L-shaped plates 19 are slidably provided on the two guide rods 18 on the same side. Grooves 20 are provided on both the left and right ends of the cover plate 3 corresponding to the L-shaped plates 19. Adjusting rods 21 are rotatably provided on both the left and right ends of the box body 1. Adjusting holes 22 are provided on the two L-shaped plates 19 corresponding to the adjusting rods 21. The adjusting rods 21 and the adjusting holes 22 are threadedly connected. Adjusting motors 23 are connected to the outer ends of the two adjusting rods 21.

[0025] Specifically, when the cover plate 3 is disassembled, the control device has its own control system. The two side adjustment motors 23 are started. The two side adjustment motors 23 are installed on both sides of the housing 1 through their own connecting plates. The adjustment motors 23 drive the adjustment rods 21 to rotate. The adjustment rods 21 and the adjustment holes 22 are threaded together, so that the L-shaped plate 19 slides relative to the guide rod 18. The L-shaped plate 19 is removed from the corresponding groove 20 for easy disassembly. After disassembly and maintenance, the cover plate 3 is installed in the housing 1. The positioning rod 16 and the positioning hole 17 are installed and positioned. The adjustment motors 23 are started and rotated in the opposite direction, so that the adjustment rods 21 rotate in the opposite direction, so that the L-shaped plate 19 slides back to its original position and is inserted into the corresponding groove 20 to achieve installation and locking.

[0026] Please see Figure 2 , Figure 4 and Figure 5 As one method of strengthening the locking: both mounting sleeves 7 are provided with a first through hole 24, and both rotating shafts 6 are provided with a second through hole 25 corresponding to the first through hole 24. A locking rod 26 is detachably provided between the first through hole 24 and the second through hole 25. Both locking rods 26 are provided with a retaining ring 27, and the retaining ring 27 and the locking rod 26 are threaded together.

[0027] Specifically, after the installation sleeve 7 is installed, the clamping rod 26 is installed corresponding to the first through hole 24 and the second through hole 25. The retaining ring 27 and the clamping rod 26 are threaded together to achieve installation reinforcement. The first through hole 24 and the second through hole 25 are set in the direction where the clamping groove 11 and the clamping plate 10 are not provided.

[0028] In summary, the overall equipment is in use: When the cover plate 3 is in the disassembly / assembly state, the control device has a built-in control system that starts the two side adjustment motors 23. The adjustment motors 23 drive the adjustment rod 21 to rotate. The adjustment rod 21 and the adjustment hole 22 are threaded together to realize the sliding adjustment of the L-shaped plate 19. The L-shaped plate 19 slides out from the groove 20, which facilitates the overall disassembly of the cover plate 3 and internal maintenance. After the internal maintenance operation is completed, the cover plate 3 is installed in the corresponding box 1. The positioning rod 16 and the positioning hole 17 are positioned together. The adjustment motor 23 rotates in the opposite direction to realize the sliding reset of the L-shaped plate 19. The L-shaped plate 19 is inserted into the corresponding groove 20 to realize the installation and locking of the cover plate 3.

[0029] When the mounting sleeve 7 is being replaced, after the cover plate 3 is completely disassembled, the mounting sleeve 7 with the spiral blade 8 is disassembled. The retaining ring 27 is rotated, and the retaining ring 27 and the retaining rod 26 are threaded together. After the retaining ring 27 is removed, the retaining rod 26 is pulled out. The mounting sleeve 7 is disassembled relative to the rotating shaft 6. The new mounting sleeve 7 is installed corresponding to the rotating shaft 6. The retaining plate 10 and the retaining groove 11 cooperate to slide and guide. After installation to the top position, the first through hole 24 and the second through hole 25 are aligned. The retaining rod 26 is inserted and installed. The retaining ring 27 and the retaining rod 26 are threaded together to lock and achieve installation locking, which facilitates individual replacement and reduces replacement costs.

[0030] When the mixture is being stirred, the raw materials for the production of water-resistant putty are added into the box 1 through the feed funnel 4. After a certain amount of raw materials are added, the control device with its own control system starts the drive motor 13. The drive motor 13 drives the drive shaft 12 and the first gear 14 to rotate. The first gear 14 and the second gear 15 on the two side rotating shafts 6 are meshed to realize the synchronous rotation of the two side rotating shafts 6, which in turn realizes the rotation of the mounting sleeve 7 with the spiral blades 8, thus realizing the internal double-shaft spiral stirring and mixing. After the mixing is completed, the valve on the discharge pipe 5 is opened, and the internal material is discharged outward through the discharge pipe 5.

[0031] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
