Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a drainage structure of a liquid outlet of a packaging machine. Background Art

[0002] Packaging machines are machines that package products to protect and beautify them. Common packaging machines in the prior art are mainly divided into liquid packaging machines and solid packaging machines according to the materials being packaged. Liquid packaging machines are the main packaging equipment for packaging liquid products and are widely used in the food industry.

[0003] The liquid packaging machines in the prior art are mainly divided into filling and bagging, and most of the packaging of marinades, hot pot bases, etc. in the existing food industry is bagged, and the bagged liquid packaging machines in the prior art generally include a storage component, an injection component, a bag feeding component and a sealing component. The storage component contains a limited amount of liquid product, and the bag feeding component is used to send the packaging bag to the injection port of the injection component. The liquid product is injected into the packaging bag through the injection component and sealed by the sealing component arranged below the injection component. However, when replacing the liquid product, it is usually necessary to discharge the liquid product, then inject clean water for cleaning, and clean the injection pipe in the injection component before replacing the product. However, the above process has the following problems: if cleaning is performed directly, the liquid product or cleaning liquid will be sprayed into the packaging bag, thereby causing contamination of the packaging bag. At the same time, the staff is required to place the container under the injection pipe to receive the waste liquid, and finally the turnover treatment is time-consuming and labor-intensive. Utility Model Content

[0004] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides a packaging machine liquid outlet drainage structure, including

[0005] A liquid injection pipeline, the liquid injection pipeline comprises a main pipeline, a material injection port is provided at the bottom of the main pipeline, a connecting portion is provided between the material injection port and the main pipeline, and the connecting portion protrudes in the radial direction of the main pipeline;

[0006] A drainage pipe, one end of which is connected to the waste liquid treatment equipment, and the other end of which has a hole diameter that matches the diameter of the injection port; and

[0007] A connecting assembly is provided, through which the drainage pipe and the injection pipe can be detachably connected.

[0008] Furthermore, the connection component includes

[0009] A threaded sleeve, which is integrally sleeved on one end of the drainage pipe connected to the injection pipe, and can rotate along its own circumferential direction;

[0010] A moving ring, which is sleeved on the outside of the threaded sleeve and is threadedly connected to the threaded sleeve;

[0011] A fixing ring, which is fixedly sleeved on one end of the drainage pipe connected to the injection pipe, and at least one connecting piece is provided on the circumferential side of the fixing ring, and at least one of the connecting pieces is arranged at equal angles along the circumference of the fixing ring; and

[0012] A pressing rod, one end of which is movably connected to the moving ring through a connecting rod, the upper part of which is pivotally connected to the connecting piece, and the pressing rod has a pressing part protruding perpendicular to the pressing rod away from the end of the connecting rod.

[0013] The utility model injects liquid product into the packaging bag through the above-mentioned injection pipe. When the equipment needs to be cleaned for product replacement or other reasons, it is only necessary to extend one end of the drainage pipe equipped with the connecting assembly from the bottom opening of the packaging bag, so that the injection port of the injection pipe is inserted into the inner hole of the drainage pipe, and the lower surface of the connecting part is in contact with the upper surface of the fixing ring, and then the threaded sleeve is rotated to make the moving ring move along the axial direction of the threaded sleeve. Under the transmission of the connecting rod, the pressing rod is driven to move around the pivot axis between it and the fixing ring, so that the pressing part of the pressing rod is close to the upper surface of the connecting part until it abuts against the upper surface of the connecting piece, thereby realizing the rapid connection between the drainage pipe and the injection pipe. Since the drainage pipe is connected to the waste liquid treatment equipment, the waste liquid generated during cleaning can be directly input into the waste liquid treatment equipment for treatment, thereby reducing the process of midway turnover, saving time and effort, and at the same time, due to the barrier and diversion of the water distribution pipe, the waste water pollution of the packaging bag can be effectively avoided.

[0014] Furthermore, a rubber block is provided on the lower surface of the pressing part. By providing the rubber block on the lower surface of the pressing part, it is avoided that the pressing part causes an indentation on the liquid injection pipeline when pressing the liquid injection pipeline.

[0015] Furthermore, the connection assembly further includes a plurality of guide rods, which are arranged at equal angles along the annular surface of the fixing ring on the circumference of the fixing ring, and a guide channel for the movement of the connecting part is formed between the plurality of guide rods. The movement of the injection pipe is guided by the guide channel for the movement of the connecting part formed between the guide rods, thereby realizing the rapid connection between the injection pipe and the drainage pipe.

[0016] Furthermore, the connection assembly also includes a sealing gasket, a plug hole is provided on the surface of the sealing gasket corresponding to the guide rod, and the sealing gasket is installed by inserting the guide rod into the corresponding plug hole, and the sealing gasket fits the upper surface of the fixing ring. When the pressing rod presses the injection pipe and the drainage pipe together, the pressing force generated by the pressing rod causes the connection part of the injection pipe to squeeze the sealing gasket, so that the lower surface of the connection part fits the sealing gasket tightly, thereby reducing the connection gap between the injection pipe and the drainage pipe and improving the sealing performance.

[0017] Furthermore, a first positioning groove is provided at the connection between the side surface of the fixing ring and the connecting member, and the first positioning groove can accommodate one side of the connecting member.

[0018] Furthermore, a second positioning groove is provided at the connection between the side surface of the fixing ring and the guide rod, and the second positioning groove matches the side portion of the guide rod.

[0019] By providing the first positioning groove and the second positioning groove, the connecting member and the guide rod can be quickly positioned, so as to facilitate the quick installation of the guide rod and the connecting member.

[0020] Furthermore, a limiting groove is provided on the inner hole wall of the fixing ring, and a limiting protrusion matching the limiting groove is provided on the lower surface of the connecting portion. The connection and positioning of the injection pipe and the drainage pipe are achieved through the cooperation of the limiting protrusion and the limiting groove, so as to prevent the drainage pipe including the entire connecting assembly from rotating when the threaded sleeve is rotated.

[0021] The utility model has the following advantages:

[0022] The utility model injects liquid product into the packaging bag through the above-mentioned injection pipe. When the equipment needs to be cleaned for product replacement or other reasons, it is only necessary to extend one end of the drainage pipe equipped with the connecting assembly from the bottom opening of the packaging bag, so that the injection port of the injection pipe is inserted into the inner hole of the drainage pipe, and the lower surface of the connecting part is in contact with the upper surface of the fixing ring, and then the threaded sleeve is rotated to make the moving ring move along the axial direction of the threaded sleeve. Under the transmission of the connecting rod, the pressing rod is driven to move around the pivot axis between it and the fixing ring, so that the pressing part of the pressing rod is close to the upper surface of the connecting part until it abuts against the upper surface of the connecting piece, thereby realizing the rapid connection between the drainage pipe and the injection pipe. Since the drainage pipe is connected to the waste liquid treatment equipment, the waste liquid generated during cleaning can be directly input into the waste liquid treatment equipment for treatment, thereby reducing the process of midway turnover, saving time and effort, and at the same time, due to the barrier and diversion of the water distribution pipe, the waste water pollution of the packaging bag can be effectively avoided.

[0023] By arranging a rubber block on the lower surface of the pressing part, it is prevented that the pressing part causes an indentation on the liquid injection pipeline when pressing the liquid injection pipeline.

[0024] The guide channel for movement of the connecting part is formed between the guide rods to guide the movement of the injection pipe, thereby realizing the rapid connection between the injection pipe and the drainage pipe.

[0025] When the pressing rod presses the injection pipe and the drainage pipe together, the pressing force generated by the pressing rod will cause the connecting part of the injection pipe to squeeze the sealing gasket so that the lower surface of the connecting part fits tightly against the sealing gasket, thereby reducing the connecting gap between the injection pipe and the drainage pipe and improving the sealing performance.

[0026] By providing the first positioning groove and the second positioning groove, the connecting member and the guide rod can be quickly positioned, so as to facilitate the quick installation of the guide rod and the connecting member.

[0027] The cooperation between the limiting protrusion and the limiting groove realizes the connection and positioning between the injection pipe and the drainage pipe, thereby preventing the drainage pipe including the entire connection assembly from rotating when the threaded sleeve is rotated.

[0042] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0043] In this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises", or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus.

[0044] As described in the background technology, when cleaning the packaging equipment, liquid products or cleaning liquids may be sprayed into the packaging bags, thereby causing contamination of the packaging bags. At the same time, workers are required to place containers under the filling pipes to receive the waste liquids, which are then circulated and processed, which is time-consuming and laborious.

[0045] Therefore, in order to solve the above technical problems existing in the prior art, the utility model proposes a packaging machine liquid outlet drainage structure, such as Figure 1 As shown, the drainage structure includes

[0046] The injection pipeline 300, such as Figure 5As shown, the injection pipeline 300 includes a main pipeline 301, a material injection port 303 is provided at the bottom of the main pipeline 301, and a connecting portion 302 is provided between the material injection port 303 and the main pipeline 301, and the connecting portion protrudes along the radial direction of the main pipeline 301;

[0047] A drainage pipe 100, one end of which is connected to the waste liquid treatment equipment, and the other end of which has a hole diameter that matches the diameter of the injection port 303; and

[0048] A connecting assembly 200 is provided, through which the drainage pipe and the injection pipe 300 can be detachably connected.

[0049] like Figures 2~4 As shown, the above-mentioned connection assembly 200 includes

[0050] A threaded sleeve 204, which is integrally sleeved on one end of the drainage pipe 100 connected to the injection pipe 300, and the threaded sleeve 204 can rotate along its own circumference;

[0051] A movement ring 211, which is sleeved on the outside of the threaded sleeve 204 and is threadedly connected to the threaded sleeve 204;

[0052] A fixing ring 210, which is fixedly sleeved on one end of the drainage pipe 100 connected to the injection pipe 300, and at least one connecting piece 206 is provided on the circumference of the fixing ring 210, and at least one connecting piece 206 is arranged at equal angles along the circumference of the fixing ring 210; and

[0053] The pressing rod 202 has one end movably connected to the moving ring 211 through a connecting rod 203. The upper portion of the pressing rod 202 is pivotally connected to the connecting member 206. The pressing rod 202 has a pressing portion protruding perpendicular to the pressing rod at the end away from the connecting rod 203.

[0054] The utility model injects liquid product into the packaging bag through the above-mentioned injection pipe 300. When the equipment needs to be cleaned for product replacement or other reasons, it is only necessary to extend one end of the drainage pipe equipped with the connecting assembly from the bottom opening of the packaging bag, so that the injection port of the injection pipe is inserted into the inner hole of the drainage pipe, and the lower surface of the connecting part is in contact with the upper surface of the fixing ring. Then, the threaded sleeve is rotated to make the moving ring move along the axial direction of the threaded sleeve. Under the transmission of the connecting rod 203, the pressing rod 202 is driven to move around the pivot axis between it and the fixing ring, so that the pressing part of the pressing rod 202 is close to the upper surface of the connecting part until it abuts against the upper surface of the connecting part, thereby realizing the rapid connection between the drainage pipe and the injection pipe. Since the drainage pipe is connected to the waste liquid treatment equipment, the waste liquid generated during cleaning can be directly input into the waste liquid treatment equipment for treatment, thereby reducing the process of midway turnover, saving time and effort. At the same time, due to the barrier and diversion of the water distribution pipe, the waste water pollution of the packaging bag can be effectively avoided.

[0055] In addition, if Figure 3 As shown, a support ring 209 is provided at the top of the threaded sleeve, and the support ring 209 is fixedly connected to the drainage pipe 100, including but not limited to welding, fusion, bolt connection, riveting and other connection methods.

[0056] Optional, such as Figure 7 As shown, a rubber block 202A is provided on the lower surface of the pressing part in the pressing rod. By providing the rubber block 202A on the lower surface of the pressing part, it is avoided that the pressing part causes an indentation on the liquid injection pipeline when pressing the liquid injection pipeline.

[0057] Optional, such as Figure 2 As shown, the connection assembly 200 in this embodiment may further include a guide rod 208, which may be provided in plurality and arranged at equal angles on the circumference of the fixing ring 210 along the annular surface of the fixing ring 210, and a guide channel for movement of the connecting portion 302 is formed between the plurality of guide rods 208. The guide channel for movement of the connecting portion 302 formed between the guide rods 208 guides the movement of the injection pipe, so as to achieve rapid docking of the injection pipe with the drainage pipe.

[0058] Optional, such as Figure 2As shown, the connection assembly 200 in this embodiment may further include a sealing gasket 207, and a plug hole 207A is provided on the surface of the sealing gasket 207 corresponding to the guide rod 208. The sealing gasket 207 is installed by inserting the guide rod into the corresponding plug hole 207A, and the sealing gasket is attached to the upper surface of the fixing ring 210. The sealing gasket 207 may be designed as follows: Figure 2 The shape shown is that a strip sheet corresponding to the number of the above-mentioned guide rods is integrally arranged on the axial side of the CITIC ring sheet, and a plug hole 207A is opened at the position of the strip sheet corresponding to the guide rod. When the pressing rod presses the injection pipe and the drainage pipe together, the pressing force generated by the pressing rod will make the connection part of the injection pipe squeeze the sealing gasket 207, so that the lower surface of the connection part is tightly fitted with the sealing gasket, thereby reducing the connection gap between the injection pipe and the drainage pipe and improving the sealing performance.

[0059] Optional, such as Fig. 9 As shown, a first positioning groove 210B is provided at the connection between the side of the fixing ring 210 and the connecting member 206, and the first positioning groove 210B can accommodate one side of the connecting member. One side of the connecting member 206 is embedded in the first positioning groove 210B, and the upper surface of the fixing part arranged on the side contacts the lower surface of the fixing ring 210, and is fixed by means including but not limited to screws, pins, bolts, welding, fusion, riveting, etc. A second positioning groove 210C is provided at the connection between the side of the fixing ring and the guide rod, and the second positioning groove 210C matches the side of the guide rod. One side of the bottom of the guide rod is embedded in the second positioning groove 210C, and is fixed by means including but not limited to screws, pins, bolts, welding, fusion, riveting, etc. By providing the first positioning groove and the second positioning groove, the fast positioning of the connecting member and the guide rod can be realized, so as to facilitate the fast installation of the guide rod and the connecting member.

[0060] like Fig. 9 , 10 As shown, in this embodiment, a limiting groove 210A can be provided on the inner hole wall of the fixing ring 210, and a limiting protrusion 304 matching the limiting groove 210A is provided on the lower surface of the connecting portion 302. The limiting protrusion 304 cooperates with the limiting groove 210A to achieve connection and positioning between the injection pipe and the drainage pipe, thereby preventing the drainage pipe including the entire connection assembly from rotating when the threaded sleeve is rotated.
