Description

Technical Field

[0001] This invention relates to the field of food processing machinery technology, specifically to a grouting device suitable for high-temperature environments. Background Technology

[0002] Food filling machines are used in various fields, such as cake production and beverage filling. When these products are formed, the raw filling material is a highly viscous fluid, and the filling nozzle is directly above the heating medium (such as cooking oil or a baking pan). For example, CN202510972765 discloses a cake filling injection device that can achieve intermittent filling of cake filling. However, its filling position is fixed. For filling materials that need to be directly immersed in a high-temperature heating medium, when the filling port is close to the heating medium, prolonged filling intervals (such as temporary shutdowns) can cause the filling material at the filling port to mature, clogging the filling nozzle and preventing filling, or causing the filling material to spray randomly instead of falling vertically, which has certain limitations. Furthermore, different products should use appropriate filling heights, as the filling height has a significant impact on the product's appearance and texture. Summary of the Invention

[0003] In view of the problems existing in the prior art, the purpose of this invention is to provide a grouting device suitable for high-temperature environments, which can realize batch grouting and the grouting outlet is not easily blocked, thereby ensuring the efficiency of food processing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A grouting device suitable for high-temperature environments includes a gantry frame, a controller, a grouting mechanism, a metering mechanism, and a positioning mechanism; The grouting mechanism includes a fixed base and several grouting nozzles. The grouting nozzles are installed on the fixed base and arranged at intervals. The fixed base is slidably connected to the bottom of the crossbeam of the gantry frame, and the sliding direction of the fixed base is vertical. The positioning mechanism includes a lead screw, two lead screw nuts, two connecting rods, and a first driving component. The lead screw is rotatably connected to the crossbeam of the gantry frame. One end of the lead screw is a first threaded segment, and the other end is a second threaded segment. The threads of the first and second threaded segments are in opposite directions. One lead screw nut is threadedly connected to the first threaded segment, and the other lead screw is threadedly connected to the second threaded segment. The connecting rods are inclined relative to the lead screw, and the two connecting rods are symmetrically arranged. Each connecting rod corresponds to a lead screw nut. One end of each connecting rod is rotatably connected to the lead screw nut, and the other end is rotatably connected to a fixed base. The first driving component drives the lead screw to rotate. The metering mechanism includes a storage unit and several pumping components. The storage unit is located above the pumping components, and the bottom of the storage unit has a discharge hole corresponding to each pumping component. The discharge hole pipe is connected to the inlet of the pumping component. The grouting nozzle corresponds to each pumping component, and the discharge port pipe of the pumping component is connected to the grouting nozzle. The first drive unit and the pump assembly are connected to the controller.

[0005] With the above settings, the grouting mechanism is raised and lowered via a positioning mechanism to precisely position the height of the grouting nozzle. This allows for adaptation to different product processing needs and enables dynamic grouting (e.g., intermittent grouting where the nozzle is raised after grouting and moves to a set position during grouting). Of course, this invention is also applicable to static grouting, making it more versatile. Furthermore, the grouting mechanism can be raised away from the heating medium during idle periods, preventing the grout from directly maturing in the nozzle and causing blockages. Additionally, by placing the storage unit above the pump assembly, the liquid level difference facilitates the flow of viscous grout, resulting in smoother grout discharge. The multiple grouting nozzles on the grouting mechanism improve processing efficiency, and the one-to-one correspondence between the nozzles and the pump assembly ensures timely and synchronized grout supply, guaranteeing consistent batch product processing quality.

[0006] The crossbeams of the gantry frame have several perforations. This design facilitates the dispersion of moisture, preventing it from accumulating on the crossbeams and dripping into the heating medium below, thus avoiding pollution and hazard.

[0007] The gantry frame is equipped with a support bearing seat and two fixed bearing seats. The fixed bearing seats correspond one-to-one with both ends of the lead screw and are rotatably connected. The support bearing seat is rotatably connected to the middle section of the lead screw. This design ensures reliable rotation of the lead screw and provides good support force, guaranteeing stable lifting and lowering of the grouting mechanism.

[0008] The gantry frame has at least two guide sleeves on its crossbeam, and the fixed seat has guide posts that correspond one-to-one with the guide sleeves. The guide posts and guide sleeves are engaged in a guiding fit. This design ensures the stability of the fixed seat's movement, guarantees uniform grouting height, and ensures product processing quality.

[0009] The first drive unit is installed at the end of the crossbeam of the gantry frame; the controller and the metering mechanism are mounted on the legs of the gantry frame. With this design, the first drive unit, controller, and metering mechanism can be kept away from heat sources, avoiding corrosion from the motor and other components caused by the heating medium or water vapor generated by the molding slurry, thus protecting the motor and providing advantages such as safety, hygiene, and ease of cleaning.

[0010] The metering mechanism also includes a stirring blade and a second driving component. The stirring blade is located inside the storage container, and its rotating shaft extends out of the storage container and is connected to the second driving component for transmission. The second driving component drives the stirring blade to rotate; the second driving component is connected to a controller. This design ensures that the slurry does not easily settle and remains uniform, which is beneficial for ensuring product quality.

[0011] The pump assembly includes a servo motor and a magnetic pump, with the servo motor driving the magnetic pump. The discharge port pipe is connected to the feed inlet of the corresponding magnetic pump, and the grouting nozzle pipe is connected to the discharge outlet of the corresponding magnetic pump. This design results in a highly reliable pump assembly.

[0012] The gantry frame is equipped with a pipeline groove, and the pipe connecting the discharge port of the pump material assembly to the grouting nozzle is installed in the pipeline groove. The pipeline groove facilitates the arrangement and protection of the pipeline.

[0013] The outlet of the pump assembly is connected to the pipe of the grouting nozzle, and at least the part near the grouting nozzle is a flexible hose. This design facilitates the raising and lowering of the grouting nozzle and ensures unobstructed grout flow.

[0014] The gantry frame is equipped with leveling casters on its legs. This design allows for height adjustment of the entire gantry frame, enabling the entire device to be moved above the heating equipment, thus increasing its flexibility of use.

[0015] By adopting the above solution, the grouting mechanism is raised and lowered through a positioning mechanism, thereby accurately positioning the height of the grouting nozzle. This allows for adaptation to different product processing and enables dynamic grouting (e.g., intermittent grouting where the nozzle is raised after grouting and moves to a set position during grouting). Of course, this invention is also applicable to static grouting, making it more versatile. Furthermore, the grouting mechanism can be raised away from the heating medium during idle periods, preventing the grout from directly maturing in the nozzle and causing blockages. In addition, by placing the storage unit above the pump assembly, the liquid level difference facilitates the flow of viscous grout, resulting in smoother grout discharge. The multiple grouting nozzles on the grouting mechanism improve processing efficiency, and the one-to-one correspondence between the nozzles and the pump assembly ensures timely and synchronized grout supply, guaranteeing consistent batch product processing quality.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0019] like Figure 1-5 As shown, this invention discloses a grouting device suitable for high-temperature environments, comprising a gantry frame, a controller 20, a grouting mechanism, a metering mechanism, and a positioning mechanism. The controller 20 is a PLC, which is built into an electrical box for good protection. The controller 20 is mounted on the support legs 11 of the gantry frame.

[0020] The gantry frame design facilitates coordination between the grouting device and the heating equipment. Horizontal adjustment casters 13 are provided on the legs 11 of the gantry frame, with two casters on each leg 11. This allows for leveling and height adjustment, and also facilitates the movement of the grouting device, increasing its flexibility. Several perforations 14 are provided on the crossbeam 12 of the gantry frame. In a preferred embodiment, the crossbeam 12 can be a frame structure, which helps reduce weight, and the gaps between the frames form natural perforations 14. The large area of ​​the perforations 14 allows for effective dispersion of moisture, preventing moisture from accumulating on the crossbeam 12 and dripping into the heating medium below, thus avoiding contamination and hazard. Of course, if the moisture content in the processing chamber is very low, the perforations 14 on the crossbeam 12 can be omitted. Alternatively, a baffle plate 15 can be installed on the crossbeam 12 to cover the perforations 14 (this arrangement prevents debris from falling into the heating medium and causing contamination).

[0021] The grouting mechanism includes a fixed base 31 and several grouting nozzles 32. The grouting nozzles 32 are detachably mounted on the fixed base 31 and arranged at intervals. For example, the grouting nozzles 32 can be installed using some smooth rods 33 and smooth rod fasteners 34. This allows for adjustment of the horizontal position and height of the grouting nozzles 32, and also facilitates the increase or decrease of their number. The actual number of grouting nozzles 32 is adjusted according to the actual situation. The discharge direction of the grouting nozzles 32 is downward.

[0022] The fixed seat 31 is slidably connected to the lower part of the crossbeam 12 of the gantry frame, and the sliding direction of the fixed seat 31 is vertical. At least two guide sleeves can be set on the crossbeam 12 of the gantry frame, and guide posts 35 corresponding to the guide sleeves are set on the fixed seat 31. The guide posts 35 and the guide sleeves guide each other, which can ensure the movement stability of the fixed seat 31, ensure the uniformity of grouting height, and ensure the quality of product processing.

[0023] The positioning mechanism includes a lead screw 41, two lead screw nuts 42, two connecting rods 43, and a first driving component 44. A support bearing seat 17 and two fixed bearing seats 16 are provided on the gantry frame. The fixed bearing seats 16 correspond one-to-one with the two ends of the lead screw 41 and are rotatably connected. The support bearing seat 17 is rotatably connected to the middle section of the lead screw 41, thus ensuring reliable rotation of the lead screw 41 and providing good support force. One end of the lead screw 41 is designated as a first threaded section 45, and the other end is designated as a second threaded section 46. The thread directions of the first threaded section 45 and the second threaded section 46 are opposite. One lead screw nut 42 is threadedly connected to the first threaded section 45, and the other lead screw 41 is threadedly connected to the second threaded section 46. Both connecting rods 43 are inclined relative to the lead screw 41, and the two connecting rods 43 always maintain a symmetrical relationship. Each connecting rod 43 corresponds one-to-one with a lead screw nut 42. One end of the connecting rod 43 is rotatably connected to the lead screw nut 42, and the other end of the connecting rod 43 is rotatably connected to the fixed seat 31. In this way, as the lead screw 41 rotates, the two connecting rods 43 can move synchronously relative to each other, thereby ensuring that the fixed base 31 can be reliably raised and lowered. The first drive component 44 is used to drive the lead screw 41 to rotate. The first drive component 44 can be a motor, and its output shaft is connected to one end of the lead screw 41 through a coupling 47. The first drive component 44 is connected to the controller 20. In order to avoid the first drive component 44 being affected by high temperature interference or moisture corrosion, the first drive component 44 is set at the end of the crossbeam 12 of the gantry frame, that is, directly above it away from the grouting mechanism.

[0024] A metering mechanism is used to meterly supply slurry to the grouting mechanism. It is mounted on the support leg 11 of the gantry frame. The metering mechanism includes a storage unit 51, a stirring blade 52, a second drive unit 53, and several pumping assemblies 54. The stirring blade 52 is rotatably connected to the storage unit 51, with one end of its shaft extending outside the storage unit 51 and being driven by the second drive unit 53. The second drive unit 53 drives the stirring blade 52 to rotate, thereby agitating the slurry in the storage unit 51 and preventing slurry sedimentation. The second drive unit 53 can be a motor connected to a controller 20.

[0025] A pump assembly 54 is located below the storage unit 51. The pump assembly 54 includes a servo motor and a magnetic pump. The servo motor drives the magnetic pump and is connected to a controller 20. At the bottom of the storage unit 51, there are discharge holes corresponding to the pump assemblies 54. The discharge hole pipes are connected to the inlet of the magnetic pump corresponding to the pump assembly 54. Grouting nozzles 32 correspond to the pump assemblies 54, and the discharge port pipes of the magnetic pumps in the pump assembly 54 are connected to the grouting nozzles 32. A pipeline trough 18 is provided on the gantry frame. The pipes connecting the discharge port of the magnetic pump in the pump assembly 54 to the grouting nozzles 32 are placed in the pipeline trough 18 for easy pipe management and protection. Furthermore, at least the portion of the pipe connecting the discharge port of the magnetic pump in the pump assembly 54 to the grouting nozzles 32 is a flexible hose to avoid interfering with the lifting and lowering of the grouting nozzles 32.

[0026] The key to this invention lies in using a positioning mechanism to raise and lower the grouting mechanism, thereby precisely positioning the height of the grouting nozzle 32. This allows for adaptation to different product processing needs and enables dynamic grouting (e.g., intermittent grouting where the nozzle 32 is raised after grouting and moved to a set position during grouting). Of course, this invention is also applicable to static grouting, making it more versatile. Furthermore, when idle, the grouting mechanism can be raised away from the heating medium, preventing the grout from directly maturing in the nozzle 32 and causing blockages. In addition, by placing the storage unit 51 above the pump assembly 54, the liquid level difference facilitates the flow of viscous grout, resulting in smoother grout discharge. The design of multiple grouting nozzles 32 on the grouting mechanism improves processing efficiency. The one-to-one correspondence between the grouting nozzles 32 and the pump assembly 54 ensures timely and synchronized grout supply, guaranteeing consistent batch product processing quality.

[0027] The above description is merely an embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
