Description

Technical Field

[0001] This utility model relates to the field of building material production technology, specifically to a raw material addition device for putty powder preparation. Background Technology

[0002] Putty powder is a building material that is usually in powder form. It is mainly composed of inorganic cementitious materials, fillers and additives mixed in a specific formula ratio. When used, it is stirred with water to form a paste. Because putty powder has good filling and leveling capabilities, it can fill uneven areas on various base surfaces such as interior walls, exterior walls, and ceilings. At the same time, it can provide a high-quality adhesion base for subsequent decoration processes, meeting various needs of building decoration and renovation.

[0003] Existing technologies often have the following problems when used:

[0004] In the preparation of putty powder, raw materials are usually added by direct injection. However, the amount of various liquid raw materials, such as various emulsions and dispersants, that are directly injected is relatively large. In order to ensure the mixing effect of the raw materials, the mixing time of the raw materials will be longer, which will affect the mixing efficiency of the raw materials in the preparation of putty powder. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a raw material addition device for putty powder preparation, which can effectively solve the problem that the direct introduction of liquid raw materials affects the raw material mixing efficiency in putty powder preparation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a raw material addition device for preparing putty powder, including a preparation cylinder, wherein a rotating shaft is rotatably connected to the bottom surface of the preparation cylinder;

[0008] A uniform feeding assembly includes several piston feeding cylinders fixedly connected to the upper end face of a preparation cylinder. Each piston feeding cylinder has a sealing plate slidably connected to its inner wall. Two opposing side walls of each piston feeding cylinder are respectively connected to a connecting pipe and a liquid inlet pipe. The inner walls of the connecting pipe and the liquid inlet pipe are provided with one-way valves. An intermittent pushing component is slidably connected through the side walls of each piston feeding cylinder.

[0009] A raw material mixing assembly includes several stirring rods fixedly connected to the outer wall of a rotating shaft, a transfer block fixedly connected to the outer wall of the rotating shaft, and two premixing components fixedly connected to the outer wall of the transfer block.

[0010] Furthermore, the uniform feeding assembly also includes a fixed bracket fixedly connected to the upper part of the outer wall of the preparation cylinder, on which a rotary motor is fixedly installed, and the upper end of the rotating shaft passes through the top of the preparation cylinder and is fixedly connected to the output end of the rotary motor.

[0011] Furthermore, the intermittent pushing component includes several piston rods that are slidably connected to the side walls of several piston adding cylinders. The ends of the several piston rods away from the piston adding cylinders are all fixedly connected to arc-shaped abutments. A pressure spring is fixedly connected between the arc-shaped abutments and the outer wall of the piston adding cylinders. The ends of the several piston rods located inside the piston adding cylinders are fixedly connected to the side wall of the sealing plate. Two rotating feet are fixedly connected to the upper position of the outer wall of the rotating shaft. Each rotating foot is rotatably connected to a roller.

[0012] Furthermore, the premixing component includes a hollow frame fixedly connected to the outer wall of the transfer block, a rotating rod rotatably connected to the hollow frame, an impeller fixedly connected to the outer wall of the rotating rod within the hollow frame, and small stirring blades fixedly connected to both the upper and lower ends of the rotating rod.

[0013] Furthermore, the hollow frame has a funnel-shaped cross-section and a baffle is provided on the hollow frame.

[0014] Furthermore, a discharge channel is connected to the lower part of the side wall of the preparation cylinder.

[0015] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0016] This invention features a uniform feeding component. By driving the rotating frame and rollers to rotate, the rollers press against the arc-shaped abutment to push the sealing plate to slide and seal within the piston feeding cylinder. This allows several piston feeding cylinders to intermittently add various liquid raw materials to the preparation cylinder in batches, replacing the direct introduction of liquid raw materials. This helps reduce the mixing time of the raw materials and improves the mixing efficiency of the putty powder preparation.

[0017] This invention includes a raw material mixing component that drives several stirring rods to mix the combined raw materials in the preparation cylinder. At the same time, several self-rotating small stirring blades can be used to pre-mix the various liquid raw materials introduced, thereby improving the dispersion of the liquid raw materials and enhancing the mixing effect of the putty powder raw materials.

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] The present invention will be further described below with reference to the embodiments.

[0026] Example: Refer to Figures 1 to 4A raw material addition device for preparing putty powder includes a preparation cylinder 1, a uniform feeding component, and a raw material mixing component. A discharge channel 19 is connected to the lower side wall of the preparation cylinder 1, and a rotating shaft 2 is rotatably connected to the bottom surface of the preparation cylinder 1. The uniform feeding component includes several piston feeding cylinders 3 fixedly connected to the upper end face of the preparation cylinder 1. Each piston feeding cylinder 3 has a sealing plate 4 slidably connected to its inner wall. Two opposing side walls of each piston feeding cylinder 3 are respectively connected to a connecting pipe 5 and a liquid inlet pipe 6. Both the connecting pipe 5 and the liquid inlet pipe 6 have one-way valves on their inner walls. The one-way valve in the connecting pipe 5 only allows liquid to enter the piston feeding cylinder 3 from the connecting pipe 5, and the one-way valve in the liquid inlet pipe 6 only allows liquid to enter the liquid inlet pipe 6 from the piston feeding cylinder 3. The uniform feeding component also includes components fixedly connected to the preparation cylinder. A fixed bracket is located at the upper part of the outer wall. A rotary motor 8 is fixedly installed on the fixed bracket. The upper end of the rotating shaft 2 passes through the top of the preparation cylinder 1 and is fixedly connected to the output end of the rotary motor 8. An intermittent pushing component is slidably connected through the side wall of several piston adding cylinders 3. The intermittent pushing component includes several piston rods 9 that are slidably connected through the side wall of several piston adding cylinders 3. An arc-shaped abutment plate 10 is fixedly connected to the ends of several piston rods 9 away from the piston adding cylinder 3. A pressure spring 11 is fixedly connected between the arc-shaped abutment plate 10 and the outer wall of the piston adding cylinder 3. The ends of several piston rods 9 located inside the piston adding cylinder 3 are fixedly connected to the side wall of the sealing plate 4. Two rotating feet 12 are fixedly connected at the upper part of the outer wall of the rotating shaft 2. A roller 13 is rotatably connected to each rotating foot 12.

[0027] It should be noted that during the process of roller 13 pressing against arc-shaped abutment plate 10, pressure spring 11 will be in a compressed state. When sealing plate 4 slides to the limit position in piston adding cylinder 3, that is, after roller 13 moves to the middle position of arc-shaped abutment plate 10, the compressed pressure spring 11 can be used to push arc-shaped abutment plate 10 in the opposite direction, so that sealing plate 4 begins to gradually reset, so that liquid raw materials can be introduced next time.

[0028] The rotating shaft 2 is driven to rotate by the rotating motor 8, causing the rotating stand 12 and roller 13 to rotate synchronously. The roller 13 presses against and abuts several arc-shaped abutments 10 to push the piston rod 9 and sealing plate 4 to move, so that the sealing plate 4 can slide and seal inside the piston adding cylinder 3. This increases the pressure inside the piston adding cylinder 3 and causes the piston adding cylinder 3 to start introducing liquid raw materials into the preparation cylinder 1 through the liquid inlet pipe 6. This allows several piston adding cylinders 3 to intermittently add various liquid raw materials into the preparation cylinder 1 in batches, replacing the method of directly introducing liquid raw materials. This helps to reduce the mixing time of raw materials and improve the mixing efficiency of raw materials in the preparation of putty powder.

[0029] Reference Figure 1 , Figure 3 and Figure 4The raw material mixing component includes several stirring rods 7 fixedly connected to the outer wall of the rotating shaft 2. A transfer block is fixedly connected to the outer wall of the rotating shaft 2. Two premixing components are fixedly connected to the outer wall of the transfer block. The premixing components include a hollow frame 14 fixedly connected to the outer wall of the transfer block. A rotating rod 15 is rotatably connected to the hollow frame 14. An impeller 16 is fixedly connected to the outer wall of the rotating rod 15 inside the hollow frame 14. Small stirring blades 17 are fixedly connected to both the upper and lower ends of the rotating rod 15. The hollow frame 14 has a funnel-shaped structure in its lateral cross section. A baffle 18 is provided on the hollow frame 14. The baffle 18 can block one half of the impeller 16 to avoid the thrust on the impeller 16 becoming unbalanced, which is conducive to driving the impeller 16 to rotate.

[0030] During the rotation of the rotating shaft 2 driven by the rotary motor 8, several stirring rods 7 will rotate synchronously. The rotating stirring rods 7 are used to stir and mix the combined raw materials in the preparation cylinder 1. At the same time, the hollow frame 14 can also rotate relative to the raw materials. At this time, the pushing action of the raw materials on the impeller 16 can drive the rotating rod 15 to rotate, so that several small stirring blades 17 on the rotating rod 15 can rotate synchronously and premix the various liquid raw materials introduced to improve the dispersion of the liquid raw materials, thereby improving the mixing effect of the putty powder raw materials.

[0031] The working principle of this utility model is as follows:

[0032] 1. In use, first connect the connecting pipes on several piston adding cylinders 3 to the storage containers of various raw materials respectively, control the start of the rotary motor 8, drive the rotating shaft 2 to rotate, so that the rotating foot 12 and the roller 13 start to rotate synchronously, and use the roller 13 to squeeze and abut against several arc-shaped abutment plates 10 to push the piston rod 9 and the sealing plate 4 to move, so that the sealing plate 4 can slide and seal inside the piston adding cylinder 3, thereby increasing the pressure inside the piston adding cylinder 3, and causing the piston adding cylinder 3 to start to introduce liquid raw materials into the preparation cylinder 1 through the liquid inlet pipe 6. In this way, several piston adding cylinders 3 can intermittently add various liquid raw materials into the preparation cylinder 1 in batches, replacing the method of directly introducing liquid raw materials, which is beneficial to reduce the mixing time of raw materials and improve the mixing efficiency of raw materials in putty powder preparation.

[0033] 2. During the rotation of the rotating shaft 2 driven by the rotary motor 8, several stirring rods 7 will rotate synchronously. The rotating stirring rods 7 are used to stir and mix the combined raw materials in the preparation cylinder 1. At the same time, the hollow frame 14 can also rotate relative to the raw materials. At this time, the pushing action of the raw materials on the impeller 16 can drive the rotating rod 15 to rotate, so that several small stirring blades 17 on the rotating rod 15 can rotate synchronously and premix the various liquid raw materials introduced to improve the dispersion of the liquid raw materials, thereby improving the mixing effect of the putty powder raw materials.

[0034] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
