Description

Technical Field

[0001] The utility model relates to the technical field of double-component material packaging, in particular to a double-cavity nozzle bag. Background Art

[0002] In the process of industrial construction, it is common to encounter situations where two-component materials need to be used. For example, when using a two-component adhesive, one of the components is usually a viscous polyurethane prepolymer, and the other component is a paste or liquid after the curing agent and additives are mixed and dehydrated. The two components need to be stored separately and then prepared in a certain proportion when used to form an adhesive with strong bonding properties.

[0003] For the above-mentioned two-component materials, the two components are usually packaged separately by subpackaging. When mixing is required, the two components are extracted and mixed from the corresponding packages in proportion. In the mixing process, in order to ensure the performance of the materials, it is often necessary to use measuring tools such as scales for weighing. However, when the two components are mixed through the above steps at the construction site, there is usually a mixing error, especially during on-site construction, the construction environment may be relatively harsh. When mixing the two components, the weighing may be affected by factors such as dust in the environment, so that the mixing ratio of the two components cannot reach the preset value, affecting the performance of the two-component material.

[0033] Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. The various technical features in the utility model can be combined interchangeably without conflicting with each other.

[0034] The embodiment of the utility model provides a double-cavity nozzle bag, which can solve the problem of difficult storage of packaged two-component materials in the prior art and facilitates the preparation and use at the construction site.

[0035] Reference Figures 1 to 6 The double-cavity nozzle bag of this embodiment includes a bag body 100 and a sealing clamp 200. The bag body 100 is hollow to form a cavity, and a feed port 110 is provided at the upper end and the lower end of the bag body 100, respectively, and the two feed ports 110 are connected to the cavity, respectively. The sealing clamp 200 is used to separate the cavity into two accommodating cavities. The sealing clamp 200 includes a clamp seat 210 and a clamp rod 220. The clamp seat 210 is hollow to form a clamping cavity 216, and a slit 211 is provided on the side wall surface of the clamp seat 210, and the slit 211 is connected to the clamping cavity 216. The clamp rod 220 is inserted into the clamping cavity 216, and the two ends of the clamp rod 220 along its own length direction are a connecting end and a guiding end, respectively. The connecting end is connected to the clamp seat 210, and the guiding end extends out of the outside of the clamping cavity 216. The outer wall surface of the clamp rod 220 and the inner wall surface of the clamping cavity 216 jointly form a locking cavity.

[0036] It is understandable that the bag body 100 and the sealing clamp 200 are detachably connected. When the bag body 100 is connected to the sealing clamp 200, the bag body 100 is clamped in the locking cavity, and the clamp rod 220 and the clamp seat 210 are respectively in contact with the two opposite sides of the bag body 100, and the outer wall surface of the clamp rod 220 and the side wall surface of the slit 211 can provide a clamping force to the bag body 100. Under the joint action of the clamp seat 210 and the clamp rod 220, the bag body 100 is divided into two receiving bags 120, and the two receiving bags 120 are arranged up and down, and the cavity is divided into two receiving cavities, and the two receiving cavities are arranged up and down. The two feed ports 110 are respectively located at the two receiving bags 120 and are respectively connected to the two receiving cavities.

[0037] It can be understood that the cavity is used to load materials, and the materials can enter the cavity from the two feed ports 110. When the sealing clip 200 is installed on the bag body 100, the two components of the material can enter from the two feed ports 110 respectively and be stored in the two containing cavities respectively. Due to the separation of the sealing clip 200, the two components are separated and stored, and they are not affected by each other during the storage process.

[0038] It is understandable that the specific position of the sealing clip 200 on the bag body 100 can be adjusted according to the required ratio of the two groups of components, and the upper and lower positions of the sealing clip 200 can change the size ratio of the two accommodating chambers. The sealing clip 200 can be arranged in the middle of the bag body 100 along the left-right direction, or can be arranged in the upper or lower position of the bag body 100 along the left-right direction, or can be arranged at any height position between the two feeding ports 110 of the bag body 100.

[0039] With such arrangement, the double-cavity nozzle bag has universality and can store materials with two different component ratios.

[0040] It is understandable that the loading of the two components in the two accommodating chambers can be completed before on-site construction, thereby avoiding the influence of the on-site construction environment on the ratio of the two components and improving on-site construction efficiency.

[0041] It is understandable that the guide end is used to guide the bag body 100 into the clamping cavity 216. When the bag body 100 and the sealing clamp 200 need to be detached or installed, the guide end of the clamping rod 220 can be lightly pressed to increase the gap between the clamping rod 220 and the side wall of the slit 211, thereby reducing the clamping force of the clamping rod 220 on the receiving bag 120, so that the bag body 100 can slide more easily in the clamping cavity 216.

[0042] In some embodiments, the double-chamber nozzle bag further includes a sealing cover 300, two sealing covers 300 are provided, and the two sealing covers 300 are arranged one-to-one corresponding to the two feed ports 110. The sealing cover 300 can open or close the feed port 110, which is more conducive to the preservation of the material and avoids contamination of the material components.

[0043] In this embodiment, the feed port 110 is a threaded port, and the sealing cover 300 is detachably installed at the feed port 110 of the bag body 100 by means of a threaded connection, which has good sealing performance and is convenient for construction personnel to perform opening and closing operations.

[0044] In this embodiment, the two feed ports 110 are respectively disposed at the diagonal positions of the bag body 100. Figure 2 It is understandable that such a configuration can make it easier for operators to perform the filling operation, and the filling operations performed at the two feeding ports 110 will not affect each other. In particular, in this embodiment, in order to facilitate the storage and transportation of the double-cavity nozzle bag, the bag body 100 is made of soft plastic material, so that the bag body 100 can be folded, and the two feeding ports 110 after folding are located on the left and right sides of the bag body 100. Figure 7 The two feed ports 110 will not touch each other, and the two sealing covers 300 will not touch each other, thereby avoiding the waste of storage space caused by the overlapping of the two feed ports 110 or the overlapping of the two sealing covers 300.

[0045] In this embodiment, the two feed ports 110 are respectively arranged at the upper right corner and the lower left corner of the bag body 100, and the central axes of the two feed ports 110 are parallel to each other. The feed port 110 located at the upper right corner is opened to the upper right, and the feed port 110 located at the lower left corner is opened to the lower left.

[0046] Reference Figure 5 and Figure 6 In some embodiments, a clamping portion is disposed on the side wall of the clamping rod 220 . The clamping portion is extended along the length direction of the clamping rod 220 . The clamping portion has a tip 221 , and the tip 221 is disposed toward the slit 211 .

[0047] With such arrangement, the side walls of the tip 221 of the clamping portion can respectively form a clamping structure with the side walls of the gap 211, and the two containing bags 120 are respectively clamped and stabilized by the two clamping structures, thereby improving the isolation effect between the two containing cavities and preventing the two components from mixing with each other during storage.

[0048] In some embodiments, two first convex ridges 224 are disposed on the side wall surface of the clamping portion. The two first convex ridges 224 are respectively disposed on the upper and lower sides of the tip 221 and are respectively extended along the length direction of the clamping rod 220 .

[0049] It is understandable that, with such a configuration, the two first ribs 224 can increase the contact area between the clamping portion and the two containing bags 120, improve the clamping effect of the clamping structure on the containing bags 120, further ensure the clamping stability of the containing bags 120, improve the isolation effect between the two containing cavities, and avoid the two components from mixing with each other during storage.

[0050] Reference Figure 4 and Figure 6 In some embodiments, the clamping seat 210 is provided with two second convex ribs 214 , and the two second convex ribs 214 are respectively provided on the upper and lower sides of the slit 211 , and are respectively extended along the length direction of the clamping seat 210 .

[0051] It can be understood that the provision of the second rib 214 can reduce the upper and lower widths of the gap 211 and can increase the contact area between the clamping seat 210 and the receiving bag 120, thereby further enhancing the clamping ability of the clamping structure on the receiving bag 120, ensuring the stable clamping of the receiving bag 120, improving the isolation effect between the two receiving cavities, and avoiding the two components from mixing with each other during storage.

[0052] Reference Figure 4 In some embodiments, a notch 213 is provided at the end of the slit 211, and the notch 213 is provided on a side of the clamp seat 210 close to the guide end, and the notch 213 is connected to the clamping cavity 216. It can be understood that the notch 213 can provide a clearance space for the clamping rod 220 to approach the slit 211. When the bag body 100 is inserted into the locking cavity, the clamping rod 220 can approach the slit 211 to a greater extent, thereby ensuring the clamping effect of the clamping structure on the containing bag 120.

[0053] Reference Figure 3 and 5 In some embodiments, the guide end is further provided with an inclined guide portion 225, which extends obliquely toward one side of the notch 213 to form a clamping cavity 216. This arrangement makes it easier for operators to press, and also facilitates guiding the bag body 100 into the clamping cavity 216, making the disassembly and assembly between the bag body 100 and the sealing clamp 200 smoother and more convenient. In the embodiment provided with the above-mentioned guide portion 225, the notch 213 can also play a role in making way for the guide portion 225.

[0054] In this embodiment, a sphere 226 is provided at the end of the guide portion 225. The provision of the sphere 226 can prevent the end of the guide portion 225 from cutting the operator and the bag body 100, making the disassembly and assembly process between the bag body 100 and the sealing clamp 200 safer.

[0055] In some embodiments, a protrusion 222 is provided at the connecting end of the clamping rod 220, and the protrusion 222 protrudes from the outer wall surface of the clamping rod 220. A slot 212 is provided on the side wall surface of the clamping seat 210. The slot 212 is connected to the clamping cavity 216. The protrusion 222 cooperates with the slot 212, and the protrusion 222 can be snapped into the slot 212, thereby realizing the installation between the clamping rod 220 and the clamping seat 210.

[0056] It is understandable that, with such a configuration, the clamp rod 220 can be stably mounted on the clamp seat 210, the production and assembly process of the sealing clamp 200 is simple, and when one of the clamp rod 220 or the clamp seat 210 is damaged, the damaged component is replaced while the undamaged component can continue to be used, reducing material waste.

[0057] It is understandable that at least two clamping blocks are provided, and the number of the clamping slots 212 is consistent with the number of the clamping blocks to ensure the stability of the connection between the clamping rod 220 and the clamping seat 210 .

[0058] In this embodiment, the card slot 212 passes through the side wall of the clamp seat 210 , and the card slot 212 can be processed by a hole-punching process. The production process of the clamp seat 210 is simpler, and the production cost can be reduced.

[0059] In some embodiments, a limit block 223 is disposed at the connection end, the limit block 223 abuts against the end surface of the clamping seat 210 and is partially inserted into the clamping cavity 216 .

[0060] It can be understood that when installing the bag body 100 and the sealing clamp 200, the bag body 100 is inserted into the locking cavity from one side of the guide end. When the bag body 100 moves along the locking cavity to the position of the limit block 223, the limit block 223 can block the bag body 100 so that the bag body 100 does not extend out of the locking cavity, thereby ensuring that the two containing cavities are completely separated and preventing the two components from mixing with each other during storage.

[0061] In some embodiments, the clamp seat 210 is provided with anti-slip grooves 215, and a plurality of anti-slip grooves 215 are provided. The plurality of anti-slip grooves 215 are respectively protruded from the outer wall surface of the clamp seat 210. When disassembling the bag body 100 and the sealing clamp 200, the operator's hand contacts the outer wall surface of the clamp seat 210 and applies force to the clamp seat 210, so that the clamp seat 210 moves relative to the bag body 100. The anti-slip grooves 215 can increase the friction between the outer wall surface of the clamp seat 210 and the operator's hand, so that the relative sliding action between the clamp seat 210 and the bag body 100 can be achieved more smoothly.

[0062] In this embodiment, the anti-slip groove 215 is annular, and a plurality of anti-slip grooves 215 are arranged along the length direction of the clamping base 210. The distance between two adjacent anti-slip grooves 215 can be the same or different, which is not specifically limited here.

[0063] In this embodiment, in order to facilitate the calculation of the volume ratio of the two accommodating cavities, the sealing clamp 200 is extended in the left-right direction. During installation, the bag body 100 is first folded according to a preset ratio so that the bag body 100 forms the prototype of two accommodating bags 120. The left edges of the two accommodating bags 120 are aligned with each other, and the right edges of the two accommodating bags 120 are also aligned with each other. The fold between the two accommodating bags 120 is extended in the left-right direction and then the guide part 225 is inserted into the gap between the two accommodating bags 120, and the transition part 130 connecting the two accommodating bags 120 is inserted into the locking cavity. The two accommodating bags 120 extend from the two clamping structures formed between the upper and lower sides of the clamping rod 220 and the edge of the clamping seam 211, respectively. The two clamping structures clamp the two accommodating bags 120 respectively to achieve the separation of the two accommodating cavities.

[0064] When the bag body 100 is slid to the position abutting the stop block 223, it is considered that the bag body 100 is completely separated into two containing bags 120, and the two containing cavities are completely separated and not connected. It is understandable that the length of the clamp seat 210 along the left-right direction needs to be greater than or equal to the width of the cavity along the left-right direction to ensure that the sealing clamp 200 can completely separate the two containing cavities. In order to ensure the separation performance of the sealing clamp 200 on the containing cavity, in this embodiment, the length of the clamp seat 210 extending along the left-right direction is greater than the width of the cavity along the left-right direction. After the clamp seat 210 is installed on the bag body 100, the part protruding from the width of the bag body 100 can provide operation compensation. When the bag body 100 fails to slide to the position abutting the stop block 223 or when the bag body 100 is folded, the side edges of the two containing bags 120 are not completely aligned and cause errors, the part of the clamp seat 210 protruding from the width of the bag body 100 can ensure that the two containing cavities are completely separated.

[0065] After the bag body 100 and the sealing clip 200 are installed, the two sealing covers 300 are opened, and then the two components are poured into the two containing chambers respectively. After the pouring is completed, the sealing covers 300 are tightened to realize the storage of the two-component material.

[0066] The preferred implementation modes of the present invention are specifically described above, but the present invention is not limited to the described embodiments.
