Description

Technical Field

[0001] This utility model relates to the technical field of paint paste production, and in particular to a paint paste extruder. Background Technology

[0002] Printing paste, also known as pigment printing paste, is a paste-like mixture in which pigments, with the help of film-forming substances, are mechanically fixed onto the surface of fibrous fabrics to obtain colored printed patterns. Paste printing is suitable for various fibers and their blends or interwoven fabrics. Its process is simple, eliminating the need for wet processing, producing no waste liquid or washing liquid, and boasts advantages such as a complete range of usable pigments, vibrant colors, clear printed patterns, and high resistance to light and acids / alkalis. Currently, printing paste is mainly composed of pigment paste, film-forming substances, thickeners, crosslinking agents, catalysts, and other raw materials. It is processed through grinding, dispersion, mixing, thickening, and high-speed shear homogenization emulsification. The paste is then transferred from large-capacity storage tanks to small-capacity plastic drums for subsequent transportation and sales.

[0003] Currently, the dispensing of paint slurry mainly involves installing a filter nozzle with a valve on the storage tank, allowing the paint slurry to flow out of the filter nozzle into a plastic bucket under its own weight. However, this gravity-based dispensing method has several problems. Because paint slurry has a certain viscosity, its flow rate under its own weight is slow, resulting in low dispensing efficiency, especially when large quantities need to be dispensed, consuming significant time and labor costs. Furthermore, prolonged gravity-based dispensing can cause paint slurry to accumulate and clog the filter nozzle, requiring frequent manual cleaning, which not only increases labor intensity but may also contaminate the product. Additionally, when the paint slurry level in the storage tank is low, it is difficult to completely dispense it by gravity, leading to material waste. Utility Model Content

[0004] The problem to be solved by this utility model is to provide a coating paste extrusion machine that addresses the above-mentioned shortcomings in the prior art, and has the advantage of improving the efficiency of printing paste dispensing.

[0005] The above-mentioned objective of this utility model is achieved through the following technical solution: A paint paste extruder includes a frame, multiple closable limiting plates mounted on the frame, a discharge port on one of the limiting plates, a storage tank, a flexible receiving bag arranged in the storage tank, a binding port and a dispensing port on the receiving bag, a lifting drive unit mounted on the frame, and a pressure plate at the output end of the lifting drive unit. The multiple limiting plates can be enclosed to form a limiting space. The storage tank is arranged within the limiting space and is limited by the limiting space. The dispensing port passes through the storage tank and the discharge port in sequence and is used to connect a filter nozzle. The moving path of the pressure plate passes through the opening of the storage tank and can closely abut against the receiving bag.

[0006] By adopting the above technical solution, in the actual dispensing process, the lifting drive is first raised to a height sufficient to push the storage tank in. The receiving bag is installed in the storage tank with its tied opening open in the previous process to collect the paint slurry. Then, the storage tank is pushed into the limiting space, the tied opening of the receiving bag is tightened, and the limiting plate is closed. Next, the dispensing opening of the receiving bag is pulled out to the outside of the limiting plate, and a filter nozzle is installed. Then, the downward button of the lifting drive is pressed to slowly press down until the material can be slowly and evenly extruded. Pay attention to the rhythm of pressing down; do not press down continuously to avoid damaging the equipment. After the material is extruded, the lifting drive should be raised, and finally the storage tank should be removed. After the extrusion work is completed, the extruder should be returned to its pre-use state, and the power should be turned off. During this process, because the pressure plate is tightly pressed against the receiving bag, as the pressure plate presses down, the paint slurry inside the receiving bag... The coating paste, under pressure, flows rapidly from the dispensing port through the filter nozzle into the plastic bucket, greatly improving dispensing efficiency. This extrusion method effectively avoids the problem of low dispensing efficiency caused by the slow flow rate of the coating paste due to its own gravity, and also reduces the accumulation and clogging of the coating paste at the filter nozzle, reducing the frequency and labor intensity of manual cleaning. It also avoids product contamination that may be caused by manual cleaning. Even if the coating paste level in the storage tank is low, it can be squeezed out as much as possible, reducing material waste. In addition, the limiting space formed by the limiting plates can effectively limit the storage tank, ensuring the stability of the storage tank during the extrusion process, allowing the extrusion work to proceed smoothly. The receiving bag is made of flexible material, which can better adapt to the extrusion of the pressure plate, so that the coating paste can be squeezed evenly, further improving dispensing efficiency.

[0007] The present invention is further configured such that: multiple sets of magnetic strips are rotatably connected to the frame, wherein two sets of magnetic strips are symmetrically arranged and magnetically adsorbed to both sides of the limiting plate with the discharge port, and one side of the remaining limiting plate is hinged to the frame and the other side is magnetically adsorbed to other sets of magnetic strips.

[0008] By adopting the above technical solution, when using an extruder for coating paste dispensing, operators can quickly fix the limiting plate to the frame using magnetic strips, creating a limiting space for the storage tank and ensuring its stability during extrusion. After extrusion, the limiting plate can be easily removed from the frame for cleaning and maintenance of both the plate and the frame. Furthermore, this magnetic connection method offers flexibility; if the limiting plate is damaged or needs to be replaced with a different specification, there is no need to worry about replacement. Unlike traditional methods that require complex tools and operations, this method allows for easy replacement simply by releasing the magnetic strips, improving the maintainability and versatility of the equipment. Simultaneously, the magnetic attraction of the magnetic strips ensures the limiting plate is firmly fixed to the frame during operation, preventing loosening or displacement due to vibrations during extrusion, thus ensuring smooth extrusion. Furthermore, the symmetrical arrangement and rational connection of multiple sets of magnetic strips ensures even stress distribution on the limiting plate after installation, further enhancing its stability and reliability, and better meeting the actual usage requirements of coating and adhesive extrusion machines.

[0009] The present invention is further configured to include: multiple through holes formed on the bottom surface of the pressure plate, a retaining ring disposed on the through holes, an extrusion head slidably passing through the retaining ring, a baffle slidably connected to the through holes and disposed at the top of the extrusion head, and a compression spring disposed between the retaining ring and the baffle. The bottom end of the extrusion head extends out of the through holes and is arranged relative to the surface of the receiving bag.

[0010] By adopting the above technical solution, when the pressure plate presses downwards, the extrusion head first contacts the surface of the receiving bag. Due to the setting of the compression spring, the extrusion head will flexibly contract within a certain range to adapt to the unevenness of the receiving bag surface. This structure allows the extrusion head to apply pressure to the receiving bag evenly, avoiding excessive local pressure that could cause the receiving bag to rupture. At the same time, the setting of the retaining ring ensures the stability of the extrusion head during the sliding process and prevents it from deviating. When the pressure plate is lifted upwards, the compression spring will return to its original state, driving the extrusion head back to the initial position, preparing for the next extrusion operation. In addition, the arrangement of multiple through holes and the extrusion head can simultaneously extrude multiple parts of the receiving bag, improving the extrusion efficiency and ensuring that the coating paste can be more fully extruded from the receiving bag, meeting the high-efficiency and stable working requirements of the coating paste extruder.

[0011] The present invention is further configured such that the bottom end of the extrusion head is a hemispherical surface.

[0012] By adopting the above technical solution, compared with flat or sharp extrusion heads, hemispherical surfaces can better fit various shapes and curvatures of the container bag surface, making the pressure distribution more uniform. Moreover, when the hemispherical extrusion head contacts the container bag surface, the friction is relatively small, allowing it to slide more smoothly on the container bag surface and avoiding scratching the container bag.

[0013] The present invention is further configured such that these extrusion heads are evenly distributed relative to the bottom surface of the pressure plate.

[0014] By adopting the above technical solution, the evenly distributed extrusion heads can ensure that the pressure is applied evenly to all parts of the container bag, effectively avoiding the problem of container bag rupture caused by pressure concentration in a local area.

[0015] The present invention is further configured such that the lifting drive component is a hydraulic cylinder.

[0016] By adopting the above technical solution, the hydraulic cylinder has a large output force, which can provide sufficient power for the lifting and lowering of the pressure plate, ensuring that the pressure plate can apply sufficient pressure to the receiving bag, thereby fully extruding the coating slurry.

[0017] The present invention is further configured to include reinforcing ribs disposed on the top surface of the pressure plate.

[0018] By adopting the above technical solution, the reinforcing ribs can enhance the structural strength of the pressure plate, making it less prone to deformation when subjected to greater pressure.

[0019] The present invention is further configured to include at least two slide rods disposed on the reinforcing ribs and slidably passing through the frame.

[0020] By adopting the above technical solution, the slide bar can guide the lifting and lowering of the pressure plate, ensuring that the pressure plate maintains a stable and vertical movement trajectory during the lifting and lowering process, avoiding tilting or shaking of the pressure plate during lifting and lowering, so that the extrusion head can accurately act on the surface of the container bag.

[0021] In summary, the beneficial technical effects of this utility model are as follows: Because the pressure plate tightly contacts the receiving bag, as the pressure plate presses down, the paint slurry inside the receiving bag is squeezed, allowing it to quickly flow out from the dispensing port through the filter nozzle and into the plastic bucket, greatly improving dispensing efficiency. Moreover, this squeezing method effectively avoids the problem of low dispensing efficiency caused by the slow flow rate of the paint slurry due to its own gravity, and also reduces the accumulation and blockage of paint slurry at the filter nozzle, reducing the frequency and labor intensity of manual cleaning. It also avoids product contamination that may occur due to manual cleaning. Even if the paint slurry level in the storage tank is low, it can be squeezed out as much as possible, reducing material waste. In addition, the limiting space formed by the limiting plates can effectively limit the storage tank, ensuring its stability during the squeezing process and allowing the squeezing work to proceed smoothly. The receiving bag, made of flexible material, can better adapt to the squeezing of the pressure plate, allowing the paint slurry to be squeezed evenly, further improving dispensing efficiency.

Detailed Implementation

[0025] To make the technical means, creative features, objectives and effects of this utility model clearer and easier to understand, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Reference Figure 1The present invention discloses a coating paste extrusion machine, comprising a frame 1, multiple opening and closing limiting plates 2 mounted on the frame 1, a discharge port 21 opened on one of the limiting plates 2, a storage tank 3, a flexible receiving bag 4 arranged in the storage tank 3, a binding port 41 and a dispensing port 42 opened on the receiving bag 4, a lifting drive component 5 set on the frame 1, a pressure plate 7 set at the output end of the lifting drive component 5 and having multiple extrusion components 6, a reinforcing rib 71 set on the top surface of the pressure plate 7, and two slide rods 8 set on the reinforcing ribs 71 and slidingly passing through the frame 1. Multiple limiting plates 2 can be enclosed to form a limiting space 22. The storage tank 3 is arranged in the limiting space 22 and is limited by the limiting space 22. The dispensing port 42 passes through the storage tank 3 and the discharge port 21 in sequence and is used to connect the filter nozzle (not shown in the figure). The lifting drive component 5 is set as a hydraulic cylinder. The moving path of the pressure plate 7 passes through the opening of the storage tank 3 and can closely contact the receiving bag 4.

[0027] In the actual dispensing process, first, the lifting drive 5 is raised to a height sufficient to push the storage tank 3 in. The receiving bag 4 is installed in the storage tank 3 with its binding opening 41 open in the previous process to collect the paint slurry. Then, the storage tank 3 is pushed into the limiting space 22, and the binding opening 41 of the receiving bag 4 is tightened. The limiting plate 2 is closed. Then, the dispensing opening 42 of the receiving bag 4 is pulled out to the outside of the limiting plate 2, and a filter nozzle is installed. Then, the downward button of the lifting drive 5 is pressed down slowly until the material can be slowly and evenly extruded. Pay attention to the rhythm of the downward press; do not press continuously to avoid damaging the equipment. After the material is extruded, the lifting drive 5 should be raised, and finally the storage tank 3 should be removed. After the extrusion work is completed, the extruder should be returned to its pre-use state, and the power should be turned off. During this process, because the pressure plate 7 is tightly pressed against the receiving bag 4, as the pressure plate 7 is pressed down, the contents of the receiving bag 4... The paint slurry, under pressure, flows rapidly from the dispensing port 42 through the filter nozzle into the plastic bucket, greatly improving dispensing efficiency. This extrusion method effectively avoids the problem of low dispensing efficiency caused by the slow flow rate of the paint slurry due to its own gravity, and also reduces the accumulation and blockage of paint slurry at the filter nozzle, reducing the frequency and labor intensity of manual cleaning. It also avoids product contamination that may be caused by manual cleaning. Even if the paint slurry level in the storage tank 3 is low, it can be squeezed out as much as possible, reducing material waste. In addition, the limiting space 22 formed by the limiting plate 2 can effectively limit the storage tank 3, ensuring the stability of the storage tank 3 during the extrusion process, so that the extrusion work can be carried out smoothly. The receiving bag 4 is made of flexible material, which can better adapt to the extrusion of the pressure plate 7, so that the paint slurry can be evenly extruded, further improving dispensing efficiency.

[0028] To facilitate the opening and closing of the limiting plate 2, multiple sets of magnetic strips 23 are rotatably connected to the frame 1. Two sets of magnetic strips 23 are symmetrically arranged and magnetically adsorbed to both sides of the limiting plate 2 with the discharge port 21. The remaining limiting plates 2 are hinged to the frame 1 on one side and magnetically adsorbed to the other sets of magnetic strips 23 on the other side. When the extruder is used for coating slurry dispensing, the operator can quickly fix the limiting plate 2 to the frame 1 using the magnetic strips 23, so that the limiting plate 2 encloses a limiting space 22 for placing the storage tank 3, ensuring the stability of the storage tank 3 during the extrusion process. After the extrusion work is completed, the limiting plate 2 can be easily removed from the frame 1, facilitating cleaning and maintenance of the limiting plate 2 and the frame 1. In addition, this magnetic connection method also has a certain degree of flexibility. If the limiting plate 2 is damaged or needs to be replaced with a different specification of limiting plate 2, there is no need for complicated procedures. The tools and operations are simple; replacement can be performed by simply releasing the magnetic strip 23, improving the maintainability and versatility of the equipment. Simultaneously, the magnetic attraction of the magnetic strip 23 ensures that the limiting plate 2 is firmly fixed to the frame 1 during operation, preventing loosening or displacement due to vibrations or other factors during extrusion, thus ensuring the smooth operation of the entire extrusion process. Furthermore, the symmetrical arrangement and reasonable connection of multiple sets of magnetic strips 23 ensure that the limiting plate 2 is subjected to uniform force after installation, further enhancing its stability and reliability, and better meeting the actual usage requirements of the coating paste extruder.

[0029] Reference Figure 2The extrusion member 6 includes multiple through holes 61 evenly distributed on the bottom surface of the pressure plate 7, retaining rings 62 disposed on the through holes 61, an extrusion head 63 slidably passing through the retaining rings 62, a baffle 64 slidably connected to the through holes 61 and disposed at the top of the extrusion head 63, and a compression spring 65 disposed between the retaining rings 62 and the baffle 64. The bottom end of the extrusion head 63 extends out of the through holes 61 and is arranged relative to the surface of the receiving bag 4; the bottom end of the extrusion head 63 is hemispherical. When the pressure plate 7 presses downwards, the extrusion head 63 first contacts the surface of the receiving bag 4. Due to the setting of the compression spring 65, the extrusion head 63 will flexibly contract within a certain range to adapt to the unevenness of the surface of the receiving bag 4. This structure allows the extrusion head 63 to apply pressure to the receiving bag 4 evenly, avoiding excessive local pressure that could cause the receiving bag 4 to rupture. At the same time, the setting of the retaining ring 62 ensures the stability of the extrusion head 63 during the sliding process, preventing it from shifting. When the pressure plate 7 is lifted upwards, the compression spring 65 will return to its original state, driving the extrusion head 63 back to its initial position, preparing for the next extrusion operation. Meanwhile, the arrangement of multiple through holes 61 and the extrusion head 63 can simultaneously extrude multiple parts of the receiving bag 4, improving extrusion efficiency and ensuring that the paint slurry can be more fully extruded from the receiving bag 4, meeting the high-efficiency and stable working requirements of the paint slurry extruder. Compared to flat or sharp-shaped extrusion heads 63, hemispherical surfaces can better conform to various shapes and curvatures of the container bag 4 surface, resulting in more uniform pressure distribution. Moreover, when the hemispherical extrusion head 63 contacts the surface of the container bag 4, the friction is relatively small, allowing it to slide more smoothly on the surface of the container bag 4 and avoid scratching the container bag 4.
