Description

Technical Field

[0001] The utility model relates to the technical field of sauce filling equipment, in particular to a self-lubricating blocking gun. Background Art

[0002] Currently, after the sauce is processed, it needs to be quantitatively filled using a filling machine, and a blocking gun is one of the key components of the filling machine to complete quantitative filling. In the prior art, the blocking gun mainly consists of a drive device, a sliding sleeve, and a discharge gun head, which are coaxially connected from top to bottom. The sliding sleeve is connected to the discharge gun head and contains a blocking rod that can reciprocate along its axial direction. The blocking rod is in driving connection with the drive device. In addition, the discharge gun head has an injection pipe interface connected to its interior on the side wall. During use, the sauce is fed from the injection pipe into the discharge gun head via the injection cylinder and discharged from the discharge port at the lower end of the discharge gun head. When the sauce is injected, the blocking rod is driven by the drive device and is in an upward and raised state, not blocking the injection pipe interface and the discharge port of the discharge gun head. After the sauce is injected, the blocking rod is driven by the drive device and moves downward along the side wall of the discharge gun head, blocking the injection pipe interface and the discharge port of the discharge gun head.

[0003] In the patent publication number CN218434883U, the applicant proposed a blocking gun for sauce filling. This blocking gun inflates the blocking rod while filling the material, and uses the flushing effect of the airflow to prevent the sauce from adhering to the discharge port of the feed gun head and the lower end surface of the blocking rod, thereby solving the problem of sauce dripping on the bag opening of the packaging bag and the discharge port of the feed gun head being corroded by the sauce. However, after long-term use of this blocking gun, the applicant found that because the drive device needs to frequently drive the blocking rod back and forth for quantitative filling, during this process, the blocking rod will rub against the inner wall of the sliding sleeve and the feed gun head and generate heat, which will not only accelerate the wear of the blocking rod and shorten its service life, but also reduce the consistency of the filled sauce, making it difficult to ensure the quantitative accuracy during the filling process. Based on this, the applicant made further improvements and optimizations to this blocking gun for sauce filling. Utility Model Content

[0030] Example 1:

[0031] The utility model provides a self-lubricating blocking gun.

[0032] In one embodiment of the present invention, a self-lubricating blocking gun is arranged on a filling machine 1 and performs quantitative filling of sauce. It includes a blocking gun body 2 and a liquid supply component. A connector 3 is provided on the sliding sleeve of the blocking gun body 2. The connector 3 is connected to the inner cavity of the sliding sleeve. The liquid supply component transports lubricating liquid to the inner cavity of the sliding sleeve through the connector 3.

[0033] It should be noted that in the self-lubricating blocking gun of the present invention, the blocking gun body 2 adopts a blocking gun for sauce filling proposed by the applicant in the patent with publication number CN218434883U. The blocking gun for sauce filling includes a driving device, a sliding sleeve and a discharge gun head. The blocking gun for sauce filling avoids the problem of sauce dripping on the bag opening of the packaging bag and the discharge port of the discharge gun head being corroded by the sauce. Its detailed structure and working principle are not described here.

[0034] Specifically, if Figures 1 to 3 As shown, in the self-lubricating blocking gun of the present invention, a connector 3 is provided on the sliding sleeve of the blocking gun body 2, and the connector 3 is connected to the inner cavity of the sliding sleeve, so that the liquid supply assembly can deliver lubricating liquid to the inner cavity of the sliding sleeve through the connector 3, resulting in a simple and reasonable structural design. Furthermore, the installation position of the connector 3 is preferably set at the lower end of the sliding sleeve and close to the blanking gun head. The liquid supply assembly can adopt a liquid supply system consisting of a lubricating liquid storage tank, a pumping device (such as a peristaltic pump, a syringe pump, etc.), and a connecting pipe. That is, the pumping device can deliver the lubricating liquid in the lubricating liquid storage tank through the connecting pipe and the connector 3 to the inner cavity of the sliding sleeve and the blanking gun head. When the lubricating liquid is delivered to the sliding sleeve under the action of the liquid supply component, the lubricating liquid will flow along the contact surface between the blocking rod and the sliding sleeve and the inner wall of the feeding gun head, thereby reducing the friction between the blocking rod and the sliding sleeve and the inner wall of the feeding gun head, improving the smoothness of the reciprocating movement of the blocking rod, thereby slowing down the wear of the blocking rod, extending its service life, and reducing maintenance and replacement costs; at the same time, the lubricating liquid can also cool and reduce the temperature of the blocking rod, thereby effectively reducing the heat generated by the blocking gun during operation, thereby protecting the internal parts of the blocking gun from damage by high temperature, and ensuring the stability and durability of the blocking gun. It can be understood that since the blocking rod can greatly slow down its wear rate under the action of the lubricating liquid, it can ensure the consistency of the quantitative filling of the sauce, ensure the quantitative accuracy of the blocking rod during the filling process, and be reliable in use.

[0035] It is worth noting that the lubricating liquid is preferably edible alcohol in the prior art. Edible alcohol has the characteristics of being harmless to the human body, having good compatibility with a variety of materials (will not cause corrosion damage to the material structure) and being volatile. Therefore, it can not only ensure the lubrication effect on the blocking rod, but also ensure the safety of the sauce and the quality of the product.

[0036] In one embodiment, the fluid supply assembly includes a hydraulic pump, a fluid reservoir 4, and a fluid infusion tube 5. The fluid reservoir 4 is used to store lubricating fluid, and the hydraulic pump is detachably connected to the fluid reservoir 4 and the connector 3 via the fluid infusion tube 5. As can be understood, the hydraulic pump can deliver the lubricating fluid in the fluid reservoir 4 via the fluid infusion tube 5 to the contact surface between the blocking rod, the sliding sleeve, and the inner wall of the feed gun head, thereby lubricating and cooling the blocking rod and ensuring reliable operation.

[0037] In another embodiment, specifically, Figure 1 and Figure 2As shown, the liquid supply assembly includes a liquid tank 4 and a liquid infusion tube 5. The liquid tank 4 is detachably mounted on the top of the filling machine 1 and is located above the blocking gun body 2. The two ends of the liquid infusion tube 5 are detachably connected to the liquid tank 4 and the connector 3, respectively. As a result, the lubricating liquid can automatically flow from the liquid infusion tube 5 and the connector 3 under the action of gravity to the contact surface between the blocking rod, the sliding sleeve, and the inner wall of the blanking gun head, thereby lubricating and cooling the blocking rod. Compared with the method of using a hydraulic pump to extract the lubricating liquid, the method of automatically delivering the lubricating oil by utilizing the height difference between the liquid tank 4 and the blocking gun body 2 is more cost-effective, does not require the maintenance or replacement of the hydraulic pump, and has a simpler structural design.

[0038] In one embodiment, the liquid supply assembly further includes a housing 6 for placing the liquid storage tank 4. An opening for placing the liquid storage tank 4 is formed on the top of the housing 6. A clamp 7 for detachably connecting to the filling machine 1 is provided on the outer wall of the housing 6. Specifically, Figure 1 and Figure 2 As shown, the housing 6 can provide a stable and reliable installation and placement position for the liquid storage tank 4, preventing the liquid storage tank 4 from accidentally falling due to external environmental factors. Furthermore, the opening formed on the top of the housing 6 makes it easy for workers to take and replace the liquid storage tank 4. It can be understood that the clamp 7 provided on the outer wall of the housing 6 enables workers to firmly install the housing 6 on the grouting machine, and is easy to disassemble and install, which is conducive to maintenance.

[0039] In one embodiment, a handle 8 is formed on the outer wall of the liquid storage tank 4, and a through slot 9 for the handle 8 to pass through is formed on the side wall of the housing 6. Figure 2 and Figure 3 As shown, the handle 8 on the outer wall of the liquid storage tank 4 not only makes it convenient for the staff to take out the liquid storage tank 4 from the shell 6, but also can achieve circumferential limitation of the liquid storage tank 4 by plugging the handle 8 into the through groove 9, thereby improving the connection stability between the liquid storage tank 4 and the infusion tube 5, ensuring the delivery effect of the lubricating liquid, and stable and reliable use.

[0040] In one embodiment, a weight sensor and an audio playback device in communication with the weight sensor are provided on the bottom surface of the inner cavity of the housing 6. Figure 2As shown, by arranging a weight sensor on the bottom surface of the inner cavity of the shell 6 and setting a (mild upper limit) critical preset value for the weight sensor, the weight of the liquid storage tank 4 can be monitored in real time, thereby detecting the real-time storage amount of the lubricating fluid in the liquid storage tank 4; at the same time, since the weight sensor is also communicated with the audio playback device, the audio playback device can be a speaker, buzzer, sound and light alarm, etc. in the prior art. When the storage amount of the lubricating fluid in the liquid storage tank 4 is insufficient, the weight sensor reaches the critical preset value and causes the audio playback device to sound an alarm, thereby reminding the staff to replace the liquid storage tank 4 or replenish the lubricating fluid, thereby ensuring the storage amount of the lubricating fluid in the liquid storage tank 4 and ensuring the lubrication and cooling effect on the blocking rod.

[0041] In another embodiment, a mounting base for supporting the liquid storage tank 4 is provided in the housing 6, an elastic member is provided between the mounting base and the housing 6, and a stopper for contacting the mounting base is provided near the top opening of the housing 6. It can be understood that Figure 2 As shown, the mounting seat can firmly support the liquid storage tank 4, preventing the liquid storage tank 4 from tilting in the housing 6, thereby causing lubricating liquid residue and reducing the utilization rate of the lubricating liquid. Furthermore, since an elastic member is provided between the mounting seat and the shell 6, the elastic member is preferably a spring in the prior art, which has the characteristics of compact structure, easy material acquisition, and large elastic deformation force. When the liquid storage tank 4 filled with lubricating liquid is placed on the mounting seat, the liquid storage tank 4 and the mounting seat move downward under the action of gravity. At this time, the elastic member is gradually in a compressed state. As the lubricating liquid in the liquid storage tank 4 is continuously lost and transported to the sliding sleeve, the weight of the liquid storage tank 4 gradually becomes lighter, and the elastic member gradually rebounds and returns to its initial state, thereby pushing the mounting seat and the liquid storage tank 4 to rise and making the top and partial bottle body of the liquid storage tank 4 extend out of the shell 6. At this time, the staff can intuitively check the position status of the liquid storage tank 4 extending out of the shell 6, and know that the liquid storage tank 4 should be replaced or lubricating oil should be added. The structural design is ingenious and reasonable, which can not only effectively prevent the situation of insufficient lubricating oil supply, but also ensure the lubrication effect of the blocking rod. It is reliable to use and is convenient for the staff to take and replace the liquid storage tank 4. In addition, it is obvious that by setting a stop block in the middle near the top of the shell 6, it is possible to prevent the mounting seat and the liquid storage tank 4 from being pushed out during the upward movement, effectively preventing safety accidents caused by the liquid storage tank 4 falling off from the shell 6, and ensuring the stability of the connection between the infusion tube 5 and the liquid storage tank 4.

[0042] In one embodiment, a scale is provided at the notch of the through slot 9 along its extending direction, and a marking structure for pointing to the scale is provided at a position corresponding to the through slot 9 on the mounting base. Figure 2 and Figure 3As shown, since the through groove 9 extends along the height direction of the shell 6 and a scale is set at the notch of the through groove 9, when the mounting seat moves upward, the identification structure on the mounting seat can point to the scale, thereby being able to feed back the moving distance of the mounting seat and the liquid storage tank 4 to the staff, thereby enabling the staff to intuitively know and judge the real-time storage amount of lubricating oil in the liquid storage tank 4, which is convenient to use.

[0043] In one embodiment, the liquid supply assembly further includes a regulator 10 for regulating the flow rate of the lubricating liquid. Figure 2 As shown, by arranging the regulator 10 on the infusion tube 5, the staff can adaptively adjust the delivery and supply speed of the lubricating oil according to different usage conditions, making the use more flexible and convenient.

[0044] In one embodiment, at least two connectors 3 are provided on the sliding sleeve of the blocking gun body 2. Specifically, Figure 2 As shown, since at least two connectors 3 are provided on the sliding sleeve of the blocking gun body 2, lubricating oil can be delivered to the sliding sleeve and the blocking rod at multiple points, so that the lubricating oil covers the contact surface of the sliding sleeve and the inner wall of the blanking gun head more comprehensively and evenly, thereby ensuring the lubrication and cooling effect on the blocking rod.

[0045] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
