Description

Technical Field

[0001] This utility model relates to the technical field of sealant production equipment, and in particular to a powder feeding device for sealant production. Background Technology

[0002] In the production process of sealants, various powdered raw materials, such as calcium carbonate, fumed silica, kaolin and other functional fillers and additives, need to be precisely added to the reaction vessel or stirring equipment. The powder feeding device is the key equipment to complete this step, and its stable and reliable operation directly affects the quality of the product and the production efficiency.

[0003] In order to transport powder from the feeding device to the downstream production equipment, the feeding device's conveying pipe needs to be connected and fixed to the inlet of the downstream equipment. Currently, the industry generally uses flange connection, which uses multiple bolts and nuts for alignment and fastening.

[0004] However, this traditional flange connection method has significant shortcomings. When it is necessary to frequently change materials, clean pipes, or maintain equipment, operators must loosen or tighten multiple bolts one by one. The entire disassembly and installation process is time-consuming and labor-intensive, which significantly reduces the operating efficiency and flexibility of the production line. Especially when a set of feeding devices is required to correspond to multiple different production equipment, this non-rapid connection method becomes a bottleneck restricting production efficiency.

[0005] Therefore, this utility model proposes a powder feeding device for sealant production to overcome the shortcomings of the prior art. Summary of the Invention

[0006] In view of the problems of complex connection structure, reliance on bolt fastening leading to cumbersome and time-consuming disassembly and assembly process, and low connection efficiency of existing sealant powder feeding devices, this utility model aims to provide a sealant powder feeding device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a powder feeding device for sealant production, including: a discharge port and a conveying pipe; The outer wall of the discharge port is fixed with a sealing groove, and both the upper and lower ends of the discharge port are fixed with fixing blocks, and the fixing blocks are provided with slots. The connecting end of the conveying pipe is fixed with a sealing sleeve, and the outer walls of both the upper and lower ends of the conveying pipe are provided with push grooves. Furthermore, the feeding pipe, the discharge port, and the quick-connect mechanism are combined in the following manner: the sealing sleeve is pluggably sealed in the sealing groove; a button is slidably connected to the inner wall of the pressing groove, a sealing plate is fixedly connected to the bottom surface of the button, a return spring is connected between the bottom of the sealing plate and the bottom of the pressing groove, the sealing plate can be inserted into or disengaged from the slot when the button is pressed, and the sealing plate is driven to move upward and engage in the slot under the action of the return spring to achieve locking.

[0008] Preferably, the powder feeding device for sealant production further includes an anti-caking mechanism, which includes a processing barrel fixed to the conveying pipe and communicating with its interior, for pre-treating the powder before it enters the conveying pipe to prevent clumping.

[0009] Preferably, a drive block is fixed to the top of the processing barrel, and a rotating shaft is fixedly connected to the bottom of the drive block. The rotating shaft is vertically arranged and extends downward into the interior of the processing barrel. A blade is fixed to the outer wall of the rotating shaft, and the material is mechanically stirred by the rotation of the blade.

[0010] Preferably, a vibrating block is fixed to the bottom surface of the processing barrel. The vibrating block is used to apply vibration to the processing barrel. Through the synergistic effect of external vibration and internal stirring, the dispersion effect of the powder is further enhanced, ensuring fluidity.

[0011] Preferably, a shock-absorbing pad is fixed between the bottom surface of the processing barrel and the vibrating block. The shock-absorbing pad is used to buffer the vibration generated by the vibrating block and reduce damage to the device housing, thereby improving the stability and service life of the equipment while ensuring the vibration effect.

[0012] Preferably, the processing barrel has a feed inlet on its top wall, and a sealing cap for opening and closing the feed inlet is movably connected to the feed inlet, which facilitates the addition of materials into the processing barrel and ensures the airtightness of the working environment.

[0013] Preferably, the reset spring is sleeved on the bottom of the sealing plate, with its two ends abutting against the bottom surface of the sealing plate and the bottom of the pressing groove, respectively. This structural layout makes the spring's force application more stable and direct.

[0014] Preferably, the push groove, button, sealing plate, fixing block and card slot are all symmetrically arranged vertically with respect to the central axis of the feed pipe and the discharge port. The symmetrical structure makes the force on the connection mechanism more uniform when locking, which improves the reliability and stability of the connection.

[0015] This utility model has the following beneficial effects: 1. This utility model solves the problems of cumbersome operation, long time consumption, and low installation efficiency when connecting the feeding device's conveying pipe to the downstream equipment's discharge port by setting a quick locking mechanism consisting of a button, a sealing plate, a return spring, and a slot, and cooperating with the sealing sleeve and the sealing groove for sealing connection.

[0016] 2. This utility model solves the problem of powder materials commonly used in sealant production being prone to clumping, having poor flowability, and being difficult to feed due to adhesion or friction by setting an internal stirring assembly consisting of a drive block, a rotating shaft, and a paddle inside the processing barrel, combined with a vibrating block set at the bottom of the processing barrel. It achieves the effect of synergistic action between internal stirring and external vibration, keeping the material in a loose state at all times, effectively overcoming the friction and adhesion between powder materials, and ensuring smooth feeding.

[0017] 3. This utility model solves the problem in the prior art where the vibration of the vibration device is directly transmitted to the equipment box or the ground when the vibration device is working, resulting in equipment damage or excessive noise, by setting an anti-vibration pad between the bottom surface of the processing barrel and the vibration block.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in 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 a part of the embodiments of this utility model, and not all of them. 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. Example

[0021] Please refer to Figures 1 to 4 This utility model provides a powder feeding device for sealant production, which aims to solve the problems of cumbersome connection and installation of powder feeding devices with production equipment, low efficiency, and powder clumping leading to poor feeding in the prior art.

[0022] Please refer to Figure 1 and Figure 2 The sealant powder feeding device includes a discharge port 9 and a conveying pipe 1 detachably connected to the discharge port 9. A sealing groove 8 is fixed to the outer wall of the connecting end of the discharge port 9, and fixing blocks 10 are fixed to both the upper and lower ends of the discharge port 9. A slot 7 on the fixing block 10 is used to achieve final locking of the device. Correspondingly, a sealing sleeve 4 is fixed to the connecting end of the conveying pipe 1. The sealing sleeve 4 is used to detachably seal within the sealing groove 8 to form a preliminary sealing structure. To achieve quick and stable locking, push-button grooves 3 are provided on the outer walls of both the upper and lower ends of the conveying pipe 1. The inner walls of the push-button grooves 3 are slidably connected. There is a button 5, and a sealing plate 6 is fixedly connected to the bottom surface of the button 5. The size and structure of the sealing plate 6 are adapted to the slot 7, and it can be inserted into or released from the slot 7 when the button 5 is pressed. In order to provide automatic locking force, a return spring 11 is connected between the bottom of the sealing plate 6 and the bottom of the pressing groove 3. The return spring 11 is used to drive the sealing plate 6 to move upward and engage in the slot 7 when the button 5 is released to achieve locking. Through this quick connection and locking mechanism composed of the sealing sleeve 4 and the sealing groove 8, as well as the button 5, the sealing plate 6, the slot 7 and the return spring 11, the installation and disassembly process is greatly simplified.

[0023] Please refer to Figure 4The core component of the anti-caking mechanism 2 is the processing barrel 206. The processing barrel 206 is fixed to the conveying pipe 1 and communicates with the inside. It is used to contain and process powdery materials. The top wall of the processing barrel 206 is provided with a feed inlet 202. A sealing cover 205 for opening and closing the feed inlet 202 is movably connected to the feed inlet 202. There are stirring and vibration components working together inside and outside the processing barrel 206. The internal stirring component includes a drive block 201 fixed to the top of the processing barrel 206, a rotating shaft 203 fixed to the bottom of the drive block 201 and vertically set and extending downward into the processing barrel 206, and a paddle 204 fixed to the outer wall of the rotating shaft 203. The external vibration component includes a vibration block 208 fixed to the bottom surface of the processing barrel 206, and a shock-absorbing pad 207 set between the bottom surface of the processing barrel 206 and the vibration block 208.

[0024] In actual operation, the drive block 201 drives the rotating shaft 203 and the blade 204 to rotate, mechanically stirring the material. At the same time, the high-frequency vibration generated by the vibrating block 208 is transmitted to the entire processing barrel 206 through the anti-vibration pad 207. The anti-vibration pad 207 effectively transmits the vibration while buffering the vibration generated by the vibrating block 208 and reducing damage to the device housing, ensuring that the powder can overcome its own adhesion and friction and always remain loose and have good flowability.

[0025] In a preferred embodiment, in order to provide a more stable locking force under vibration conditions and to make the structure more compact, the return spring 11 is sleeved on the bottom of the sealing plate 6, with its two ends abutting against the bottom surface of the sealing plate 6 and the bottom of the pressing groove 3, respectively, so that the force of the return spring 11 can be evenly applied to the sealing plate 6, ensuring smooth insertion or release from the locking groove 7.

[0026] As another preferred embodiment, in order to ensure the structural stability of the connecting mechanism under stress, the push groove 3, button 5, sealing plate 6, fixing block 10 and slot 7 are all symmetrically arranged vertically with the central axis of the feed pipe 1 and the discharge port 9 as the reference. This symmetrical layout can effectively disperse and balance the stress at the connection point, prevent structural deformation or connection failure caused by excessive force on one side, thereby enhancing the reliability and durability of the entire connecting mechanism.

[0027] Working principle: When it is necessary to prevent the powder from clumping, the sealing cover 205 is opened, and the material enters the processing barrel 206 through the feed inlet 202. At this time, the anti-clumping mechanism 2 is activated. The drive block 201 located at the top of the processing barrel 206 drives the rotating shaft 203 to rotate. The rotating shaft 203 drives the paddle 204 on the outer wall to rotate synchronously, mechanically stirring the powder in the processing barrel 206. At the same time, the vibrating block 208 fixed to the bottom of the processing barrel 206 is activated and generates high-frequency vibration. The vibration is transmitted to the processing barrel 206 through the anti-vibration pad 207. The anti-vibration pad 207 effectively transmits the vibration while buffering the vibration generated by the vibrating block 208 and reducing damage to the device housing. Through the synergistic effect of the stirring of the internal paddle 204 and the vibration of the external vibrating block 208, the material overcomes the adhesion and friction, and always maintains a loose and good flow state, so as to facilitate subsequent conveying through the conveying pipe 1. When connecting this device to downstream equipment, first align the feed pipe 1 with the outlet 9, insert the sealing sleeve 4 at the docking end of the feed pipe 1 into the sealing groove 8 at the docking end of the outlet 9 to achieve initial docking and sealing. In this state, press the buttons 5 located on the upper and lower sides of the feed pipe 1. The buttons 5 slide downward in the pressing groove 3, driving the sealing plate 6 fixed on the bottom surface to move downward synchronously and compress the return spring 11. At this time, push the feed pipe 1 to the docking position, so that the sealing plate 6 is directly below the slot 7 on the fixed block 10. Then release the button 5. After the return spring 11 loses pressure, when the button 5 is released, it drives the sealing plate 6 to move upward and engage in the slot 7 to achieve locking. Under the elastic force of the return spring 11, the sealing plate 6 bounces upward and is firmly locked into the slot 7, thereby quickly locking the feed pipe 1 and the outlet 9. When disassembly is required, press the button 5 again, and the sealing plate 6 moves downward and disengages from the slot 7. At this time, the feed pipe 1 can be pulled out. The operation is simple and quick.
