Description

Technical Field

[0001] This utility model relates to the field of glue supply system technology, and more specifically, to a glue supply device that allows for easy replacement of the pressure plate. Background Technology

[0002] In large industrial sectors such as automobile manufacturing and wind turbine blade bonding, two-component epoxy / polyurethane adhesives commonly use 55-gallon (approximately 208L) industrial drum dispensing systems due to the need for precise control of the mixing ratio. These systems consist of two independent dispensing units, each comprising a heavy-duty lift, plunger platen, dispensing piping, and dynamic mixer. However, with the surge in demand for small-batch, multi-batch production from emerging industries such as precision electronics and medical devices, the application scenarios for 5-gallon (approximately 19L) small-package adhesives are expanding. Existing dispensing systems have revealed serious compatibility issues. Because the original dispensing devices are only compatible with 55-gallon dispensing units, customers often need to purchase two dispensing systems and devices, resulting in a significant increase in equipment costs.

[0003] In summary, how to make the glue supply device easy to replace is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a glue supply device that allows for easy replacement of the pressure plate, enabling a single device to adapt to multiple sizes of glue buckets, resulting in high replacement efficiency and reduced equipment investment costs for users.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] The core of this utility model is to provide a glue supply device that allows for easy replacement of the pressure plate, enabling a single device to adapt to multiple sizes of glue buckets, resulting in high replacement efficiency and reduced equipment investment costs for users.

[0039] Please refer to Figure 1 A convenient adhesive supply device for replacing the pressure plate includes a plunger pump 2, a fixing head 1, a pressure plate 3, a filter 4, and a connector 5. The fixing head 1 is installed on the plunger pump 2. The pressure plate 3 is detachably connected to the plunger pump 2. The filter 4 is connected to the plunger pump 2 through the connector 5. The connector 5 is used to adjust the distance between the filter 4 and the plunger pump 2.

[0040] It should be noted that the plunger pump 2 (piston pump) in this embodiment of the present invention can be replaced by other types of pumps, but the selection should be based on the characteristics of the adhesive, precision requirements, pressure range and cost.

[0041] In addition, the filter 4 in this embodiment is a key component to ensure the purity of the adhesive and the stability of the process. It can intercept incompatible residues (such as silicone oil contaminating polyurethane adhesive) mixed in due to batch differences of adhesive, or prevent microgel particles (pre-cured products) from entering the coating surface and causing product appearance defects.

[0042] Optionally, in some embodiments, the plunger pump 2 is provided with a frame for fixing the plunger pump 2, and the fixing head 1 is installed on the frame, which can be fixed by bolts or welding.

[0043] In use, the pressure plate 3 is installed on the plunger pump 2. The plunger pump 2 is equipped with a fixing head 1, which allows for a detachable connection between the pressure plate 3 and the plunger pump 2. This means that when applying glue with different amounts, different sizes of fixing heads 1 can be used to adapt to more different sizes of glue cans, avoiding the need for users to equip each size of glue can with a separate device. This improves the versatility of the glue supply equipment and reduces the user's equipment investment costs. Furthermore, the filter 4 is connected to the plunger pump 2 via a connector 5. The connector 5 is used to adjust the distance between the filter 4 and the plunger pump 2. The filter 4 is used to filter the glue and is connected to the plunger pump 2 via the connector 5. The connector 5 has the function of adjusting the distance between the filter 4 and the plunger pump 2, which makes it convenient to adjust the position of the filter 4 according to different glue cans. This avoids the situation where the pressure plate 3 cannot be fully adapted to different sizes of glue cans due to the fixed position of the filter 4, reducing the time for replacing adaptable parts and further improving the convenience of replacing glue cans of the appropriate size.

[0044] Please refer to Figure 1 In some embodiments, the connector 5 is a rod-shaped structure and is perpendicular to the plunger pump 2. The two ends of the connector 5 are detachably connected to the plunger pump 2 and the filter 4 respectively by bolts. In other words, the position of the filter 4 is fixed by the rod-shaped connector 5 to achieve its installation.

[0045] Optionally, in some embodiments, the connector 5 is connected to the plunger pump 2 and the filter 4 by bolts or snaps.

[0046] In the above embodiment, the two ends of the connector 5 are respectively provided with plate-shaped connecting parts, and sealing gaskets are provided between the connecting parts and the plunger pump 2 and the filter 4. The sealing gaskets can be made of rubber material, which is beneficial to increase their sealing performance.

[0047] Optionally, in some embodiments, the connector 5 adopts a telescopic rod structure. Specifically, the connector 5 has at least two rod structures, and the two rod structures are sleeved together. By sliding between the two rod structures, the distance between the plunger pump 2 and the filter 4 can be adjusted, thereby facilitating the adjustment of the position of the filter 4 according to different rubber barrels.

[0048] In other embodiments, the connector 5 has at least two rod structures, which are sleeved together and each rod structure is threaded together. Therefore, the overall length of the connector 5 can be adjusted by turning the rod structure, which can also adjust the distance between the plunger pump 2 and the filter 4, thereby facilitating the adjustment of the position of the filter 4 according to different rubber cans.

[0049] In other embodiments, the connector 5 has at least two rod structures, and the two rod structures are connected by threads. Therefore, the rod structure can be disassembled by screwing on two adjacent rod structures. Thus, by adjusting the number of rod structures, the distance between the plunger pump 2 and the filter 4 can be adjusted, thereby facilitating the adjustment of the position of the filter 4 according to different glue cans.

[0050] In other embodiments, the connector 5 can be a tubular structure such as a hose or a corrugated pipe. Specifically, the filter 4 is fixed to the top of the plunger pump 2 by a support rod or other fixing method. The height of the filter 4 can also be increased by a support rod. The filter 4 and the plunger pump 2 are connected by a tubular structure such as a hose or a corrugated pipe. Therefore, this method can avoid the need to adjust the position of the filter 4 every time, which is conducive to further improving the replacement efficiency.

[0051] Please refer to Figure 6 In some embodiments, the pressure plate 3 is provided with a mounting part 6, which is used for detachable connection with the fixed head 1. That is, the mounting part 6 enables a detachable connection with the plunger pump 2.

[0052] Optionally, in some embodiments, the number of pressure plates 3 is several, and the diameters of the several pressure plates 3 are different. By switching different pressure plates 3, it is possible to adapt to glue buckets of different sizes.

[0053] In the above embodiments, the mounting parts 6 on different pressure plates 3 have different shapes. The mounting parts 6 of the larger pressure plates 3, such as the pressure plate 3 used for 55-gallon glue buckets, are cylindrical and have several threaded holes. The fixing head 1 can fix the pressure plate 3 used for 55-gallon glue buckets by the cooperation of bolts and threaded holes. The mounting parts 6 of the smaller pressure plates 3, such as the pressure plate 3 used for 5-gallon glue buckets, are conical.

[0054] Optionally, in some embodiments, the mounting part 6 is provided with a connector 7 for detachable connection with the fixing head 1. The connector 7 is connected to the mounting part 6. That is, in order to facilitate the installation of the smaller pressure plate 3, the connector 7 is installed on the mounting part 6 of the smaller pressure plate 3. The smaller pressure plate 3 is connected to the piston pump 2 by detachable connection with the fixing head 1 through the connector 7.

[0055] Optionally, in some embodiments, the connector 7 may be fixed to the mounting portion 6 of the smaller pressure plate 3 by welding, or to the mounting portion 6 of the smaller pressure plate 3 by means of bolts or other detachable means.

[0057] Please refer to Figure 7 In some embodiments, the connector 7 is provided with a plurality of through holes 9, and a connector 5 is provided in the through holes 9. When the connector 5 is inserted into the through hole 9 and the mounting groove 8 in sequence, the connector 7 and the mounting part 6 are connected. The installation connection between the connector 7 and the mounting part 6 can be achieved by inserting the connector 5 into the through hole 9 and the mounting groove 8, which is convenient and quick.

[0058] Optionally, in some embodiments, the mounting groove 8 is an annular groove, which can reduce the difficulty of assembling the connector 5 with the mounting groove 8 and improve the ease of installation.

[0059] Optionally, in some embodiments, the connector 5 may be a bolt, and the through hole 9 on the connector 7 may be a threaded hole, so the connection between the connector 7 and the mounting part 6 can be achieved by tightening the bolt.

[0060] Please refer to Figure 1 In some embodiments, the device also includes a base plate 10, a lifting assembly 11, and a mounting frame 12. The lifting assembly 11 includes a mounting rod 112 and a lifting element 111 for controlling the distance between the mounting rod 112 and the base plate 10. The mounting frame 12 is detachably mounted on the mounting rod 112, and the plunger pump 2 is mounted on the mounting frame 12. In other words, the device is assembled as a whole by mounting the base plate 10, and the height of the plunger pump 2 can be controlled by controlling the height of the mounting rod 112 through the lifting element 111, so as to achieve the suction of glue from the glue bucket.

[0061] Optionally, in some embodiments, the lifting component 111 can be one of an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder. One end of the electric cylinder, pneumatic cylinder, or hydraulic cylinder is fixed to the base plate 10, and the other end is fixedly connected to the mounting rod 112. By extending or retracting the electric cylinder, pneumatic cylinder, or hydraulic cylinder, the height of the plunger pump 2 can be controlled to suck out the glue from the glue bucket.

[0062] In other embodiments, the lifting component 111 may be a threaded rod. Specifically, the threaded rod is rotatably mounted on the base plate 10, and the rotation of the threaded rod is controlled by a motor. The mounting rod 112 is threadedly connected to the threaded rod. By controlling the rotation of the threaded rod, the height of the plunger pump 2 can be controlled to suck out the glue from the glue bucket.

[0063] Optionally, in some embodiments, the mounting bracket 12 may be fixed to the mounting rod 112 by means of bolts or welding.

[0064] Please refer to Figure 5 In some embodiments, the mounting bracket 12 is provided with a connecting plate 13, which has a plurality of strip-shaped mounting holes 14. The connecting plate 13 is detachably connected to the mounting rod 112 through the plurality of mounting holes 14. That is, the connecting plate 13 serves as a transition piece when the mounting bracket 12 and the mounting rod 112 are connected. The connecting plate 13 has a plurality of strip-shaped mounting holes 14, and the connecting plate 13 and the mounting rod 112 can be detachably connected by bolts. The overlapping height of the connecting plate 13 and the mounting rod 112 can be adjusted through the strip-shaped mounting holes 14, thereby adjusting the initial height of the plunger pump 2 so that it can meet the height of the plunger pump 2 after the pressure plate 3 of different sizes is replaced.

[0065] Please refer to Figure 4 In some embodiments, the mounting rod 112 is provided with at least two support rods 15. The end of the support rod 15 away from the mounting rod 112 is connected to the pressure plate 3. When the pressure plate 3 is large, the support rod 15 is directly connected to the pressure plate 3 to achieve stability control of the pressure plate 3 during use.

[0066] Optionally, in some embodiments, the length of the support rod 15 is adjustable, and a support plate 16 is installed on the mounting frame 12. The end of the support rod 15 away from the mounting frame 12 is connected to the support plate 16. That is, when the size of the pressure plate 3 is small, the support plate 16 is installed on the mounting frame 12, and the support rod 15 and the support plate 16 are fixedly connected, so that the stability control of the pressure plate 3 during use can be achieved.

[0067] Optionally, in some embodiments, the strut 15 may adopt a two-section structure, and the first section is used to connect with the support plate 16. When the two sections are connected, a fixed connection with the pressure plate 3 can be achieved.

[0068] Optionally, in some embodiments, the support plate 16 is provided with a through hole 9, and the diameter of the second section support rod 15 is smaller than that of the through hole 9, so it can directly pass through the support plate 16 and connect to the pressure plate 3 without removing the support rod 15. The diameter of the first section is larger than that of the through hole 9 on the support plate 16. In use, a bolt is used, and the bolt nut is larger than that of the through hole 9 on the support plate 16. When the bolt is screwed into the end of the first section support rod 15, a fixed connection with the support plate 16 can be achieved through the bolt nut and the first section support rod 15, which further facilitates the user's replacement and improves the replacement efficiency.

[0069] In other words, the key point of this utility model is that, when applying glue with different amounts, the fixed head 1 of different sizes can be replaced to adapt to more different sizes of glue buckets, avoiding the need for users to equip each size of glue bucket with a separate device, thereby improving the versatility of the glue supply equipment and reducing the user's equipment investment costs. Furthermore, the filter 4 and the plunger pump 2 are connected by a connector 5, which is used to adjust the distance between the filter 4 and the plunger pump 2. The filter 4 is used to filter the glue and is connected to the plunger pump 2 through the connector 5. The connector 5 has the function of adjusting the distance between the filter 4 and the plunger pump 2, thereby facilitating the adjustment of the position of the filter 4 according to different glue buckets, and avoiding the situation where the pressure plate 3 cannot be fully adapted to different sizes of glue buckets due to the fixed position of the filter 4, reducing the time for replacing the adaptable parts, and further improving the convenience of replacing glue buckets of the appropriate size.
