[0022] The technical solutions of the present application will be described clearly and completely below in conjunction with the embodiments. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.
[0023] As shown in the drawings, a paste packaging hose comprises a packaging hose body 1, a cover 2 and an extrusion mechanism, the tail of the packaging hose body 1 is provided with the extrusion mechanism, the head of the packaging hose body 1 is provided with the cover 2, both sides of the packaging hose body 1 are provided with guide grooves 11, the extrusion mechanism comprises a card seat 3, a pressing plate 4 and an extrusion roller 42, the card seat 3 is in sliding fit with the guide groove 11, the pressing plate 4 is arranged in expansion on the card seat 3 on both sides, the side of the pressing plate 4 close to the packaging hose body 1 is rotationally provided with the extrusion roller 42, and the outer peripheral wall of the extrusion roller 42 is in contact with the top of the packaging hose body 1. Figs. 1 to 3 The side of the card seat 3 close to the packaging hose body 1 is provided with a mounting groove 31, both sides of the pressing plate 4 are provided with mounting blocks 41, the mounting groove 31 is fixedly provided with a guide column 32, the mounting block 41 is in sliding fit with the guide column 32, and the top of the mounting groove 31 and the top of the mounting block 41 are provided with a spring 33.
[0024] When the extrusion roller 42 extrudes the packaging hose body 1, if the thickness of the packaging hose body 1 changes due to the reduction of the material amount, the reaction force received by the extrusion roller 42 changes, the pressing plate 4 will slide downward along the guide column 32 through the mounting block 41, and the spring 33 is compressed at the same time. The deformation of the spring 33 will generate corresponding elastic force, which pushes the pressing plate 4 and the extrusion roller 42 to always be in close contact with the packaging hose body 1. This self-adaptive structure ensures that the extrusion roller 42 can adjust the extrusion force and position in real time according to the change of the material amount in the packaging hose body 1, so that the material can be continuously and uniformly extruded, and the material residue in different parts is minimized.
[0025]
[0026] The spring 33 is sleeved on the guide column 32. The spring 33 is sleeved on the guide column 32, which ensures that the spring 33 remains stable during the stretching and retracting process and does not deviate or twist. In this way, the elastic force of the spring 33 can accurately act on the mounting block 41 and the pressing plate 4, making the stretching and retracting movement of the pressing plate 4 more stable; the stable stretching and retracting movement ensures that the extrusion effect of the extrusion roller 42 on the packaging hose body 1 is always consistent, avoids material residues caused by uneven extrusion due to the instability of the spring 33, and improves the integrity of the extruded material.
[0027] The packaging hose body 1 is provided with a discharge head 5, and the outer peripheral wall of the discharge head 5 is provided with threads. The cover 2 is screwed with the discharge head 5. The threads on the outer peripheral wall of the discharge head 5 and the threads in the cover 2 are screwed with each other, and the cover 2 is tightly connected or separated by rotating. When storing and transporting, the tightly screwed cover 2 effectively prevents material leakage; when using, the cover 2 can be easily unscrewed to start extruding the material; it can prevent material leakage and deterioration during non-use, ensure the quality of the material during the entire use cycle, create good conditions for subsequent complete extrusion of the material, and reduce the problem of residues caused by material deterioration or leakage.
[0028] The discharge head 5 is communicated with a conical head 6 at the outlet. After the material flows out of the discharge head 5, it enters the conical head 6. Since the caliber of the conical head 6 gradually decreases, the material will be converged and guided during the flow-out process, forming a more concentrated discharge flow. The concentrated discharge flow facilitates the user to accurately control the extrusion direction and amount of the material, avoiding material residues around the discharge head 5.
[0029] The conical head 6 is provided with a sealing film 61. The sealing film 61 covers the outlet of the conical head 6. When not in use, it acts as a barrier to prevent material from flowing out and prevent impurities such as air and dust from entering the packaging hose body 1, maintaining the purity and stability of the material. When the material needs to be used, the sealing film 61 can be easily torn off.
[0030] The cover 2 is internally provided with a conical groove matched with the conical head 6. When the cover 2 is screwed onto the discharge head 5, the conical head 6 will be tightly embedded in the conical groove inside the cover 2, forming a sealed fit, further enhancing the sealing performance between the cover 2 and the discharge head 5, preventing material residues at the connection between the discharge head 5 and the cover 2, and protecting the conical head 6 from damage during transportation and storage, ensuring smooth discharge and reducing residues.
[0031] The mounting block 41 is matched in size with the mounting groove 31; the stability and accuracy of the stretching and retracting movement of the pressing plate 4 on the clamping seat 3 are ensured.
[0032] The packaging hose body 1 tail fixedly provided with a limiting plate 7, the limiting plate 7 is used for limiting the pressing plate 4;Limit the sliding range of the clamping seat 3, prevent the clamping seat 3 from sliding off from the packaging hose body 1.
[0033] The sealing film 61 adopts aluminum foil material. It has good barrier property, moisture resistance and corrosion resistance.
[0034] The working principle of the utility model: the packaging hose body 1 is designed for accommodating paste, gel and other fluid substances. Initially, the packaging hose body 1 is filled with materials, the cover 2 is tightly screwed through the thread cooperation with the discharge head 5, which effectively prevents material leakage and protects material quality. When the material is needed, unscrew the cover 2, squeeze the material, and the material is squeezed out from the discharge head 5. In order to prevent residual material from accumulating inside the packaging hose body 1, the residual material is squeezed out through the squeezing mechanism, reducing waste. The clamping seat 3 of the squeezing mechanism can flexibly slide in the guide groove 11 on both sides of the packaging hose body 1, and the pressing plate 4 can be extended and retracted under the action of the spring 33, and the squeezing roller 42 on it always keeps contact with the top of the packaging hose body 1. When the user pushes the clamping seat 3 to move along the guide groove 11, the squeezing roller 42 rolls along with it, continuously squeezing the packaging hose body 1, gradually squeezing the internal material out. With the reduction of material, the spring 33 will push the pressing plate 4 and the squeezing roller 42 to adaptively adjust the position, ensuring that effective pressure is always applied to the packaging hose body 1 until the material is almost completely squeezed out.
[0035] The above examples are only used to illustrate the technical method of the utility model and not to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the utility model can be modified or replaced equivalently without departing from the spirit and scope of the technical method of the utility model.
