Description

Technical Field

[0001] This invention relates to the field of filling system technology, and more particularly to a bubble suppression device for a lubricating concentrate filling system. Background Technology

[0002] After the lubricating concentrate is produced, it needs to be filled into barrels in batches on the production line. Most existing filling production lines use nozzles to inject the lubricating concentrate into the packaging barrels. Due to the high flow rate of the nozzles, the lubricating concentrate will generate a lot of foam due to the impact when injected into the packaging barrels at high speed, which will affect the quality of the product.

[0003] In response to the aforementioned situation, the production line also sets up a defoaming process after filling, which not only reduces production efficiency but also increases the cost of setting up the production line. How to effectively suppress the generation of bubbles while quickly filling the packaging barrel with lubricating concentrate during the filling operation has become an urgent problem to be solved. Summary of the Invention

[0004] To address the problems mentioned in the background section, the present invention provides a bubble suppression device for a lubricating concentrate filling system.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A bubble suppression device for a lubricating concentrate filling system is used to fill the lubricating concentrate into a packaging tank. It includes a telescopic filling head, a magnetic frame, and dispensing tubes. The telescopic filling head is installed on the filling production line. Several magnetic frames are installed on the outside of the telescopic filling head. Several dispensing tubes are installed at the bottom of the telescopic filling head. The number of magnetic frames and dispensing tubes is the same. The magnetic frame includes a fixed frame and multiple electromagnetic suction heads installed on the fixed frame.

[0007] The dispensing tube includes a curved tube and a hanging rod. The hanging rod is installed at the bottom of the curved tube. The curved tube is connected to the dispensing head but not to the hanging rod. The bottom of the curved tube has an outlet facing the inner wall of the packaging can. The hanging rod is made of a material that can be attracted by magnetic force.

[0008] Preferably, the telescopic filling head includes a telescopic cylinder, a liquid supply pipe, and a dispensing head. The telescopic cylinder is driven and controlled by a matching device installed on the production line, which can drive the dispensing head at the bottom to move vertically. The liquid supply pipe continuously introduces the lubricating concentrate to be filled provided by the production line into the dispensing head, and then flows into several dispensing pipes installed at the lower end of the dispensing head.

[0009] Preferably, each plumb bob is provided with a pair of fitting fan plates on its exterior. Each fitting fan plate is connected to a linkage ring assembly disposed above and below the plumb bob. The fitting fan plates can rotate around the central axis of the plumb bob by being driven by the linkage ring assembly.

[0010] Preferably, the fitting fan plate includes a side sealing plate, an inner extension block, and a top sealing plate. The side sealing plate is connected to the linkage ring assembly. One side of the side sealing plate is in close contact with the outer peripheral wall of the hanging rod, and the other side can be in close contact with the inner side wall of the packaging can after being flipped. The upper end of the side sealing plate extends to above the liquid outlet. The top sealing plate is installed on the upper end of the side sealing plate, and the top sealing plate has an arc edge that can fit with the inner side wall of the packaging can.

[0011] Preferably, the inner extension block is disposed on the inner side of the side sealing plate, and when the side sealing plate is tightly attached to the inner wall of the packaging tank, there is a gap between the inner extension block and the inner wall of the packaging tank, and the top of the inner extension block is located below the liquid outlet.

[0012] Preferably, the fitting fan plate is driven by the linkage ring assembly in the normal state to keep pointing in the direction of the center of the circle formed by the curved tube. The linkage ring assembly includes an outer ring, an annular hydraulic plug, an annular hydraulic cylinder, a central hydraulic cylinder, a magnetic hydraulic plug, and a return spring. A limiting ring groove for the outer ring is provided on the outer peripheral wall of the upper and lower ends of the plumb bar.

[0013] Preferably, the outer ring can rotate axially under the restriction of the limiting ring groove, but cannot move vertically. The inner side of the outer ring has a protrusion that fits against the inner wall of the limiting ring groove, so as to form a gap between the outer ring and the inner wall of the limiting ring groove to accommodate the annular hydraulic cylinder. One end of the magnetic hydraulic plug is connected to the protrusion on the inner side of the outer ring, and the other end is inserted into the annular hydraulic cylinder.

[0014] Preferably, the hanging bar is hollow inside to accommodate a central hydraulic cylinder, which is connected to an annular hydraulic cylinder. A magnetic hydraulic plug is located inside the central hydraulic cylinder, and a return spring is installed between the magnetic hydraulic plug and the inner wall of the hanging bar. Under normal conditions, the return spring keeps the magnetic hydraulic plug away from the inner wall of the packaging can, and the magnetic hydraulic plug can be attracted by the magnetic force outside the side wall of the packaging can.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The lubricating concentrate flowing out of the outlet at high speed in this invention is buffered in the space above the inner extension block and then squeezed into the relatively wide and narrow space between the inner extension block and the inner sidewall of the packaging can, flowing downwards. With the inner sidewall of the packaging can as the guiding surface, it can flow downwards at high speed and smoothly, greatly reducing the generation of bubbles. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1

[0025] Reference Figure 1-4 A bubble suppression device for a lubricating concentrate filling system includes a telescopic filling head 1, a magnetic frame 2, and dispensing pipes 3. The telescopic filling head 1 is installed on a filling production line. The telescopic filling head 1 includes a telescopic cylinder 11, a supply pipe 12, and a dispensing head 13. The telescopic cylinder 11 is driven and controlled by a cooperating device installed on the production line, which can drive the dispensing head 13 at the bottom to move vertically. The supply pipe 12 continuously introduces the lubricating concentrate to be filled provided by the production line into the dispensing head 13, and then flows into several dispensing pipes 3 installed at the lower end of the dispensing head 13. During filling, the dispensing pipes 3 extend into the packaging tank 400, thereby filling the lubricating concentrate into the packaging tank 400.

[0026] The magnetic suction frame 2 is installed on the outer wall of the dispensing head 13. The number of magnetic suction frames 2 is the same as the number of dispensing tubes 3. The magnetic suction frame 2 includes a fixing frame 21 and multiple electromagnetic suction heads 22 installed on the fixing frame 21. When the dispensing head 13 moves down and the dispensing tube 3 extends into the packaging can 400, the fixing frame 21 can move down to surround the packaging can 400. At this time, the electromagnetic suction heads 22 are close to or even pressed against the packaging can 400.

[0027] The dispensing tube 3 includes a curved tube 31, a hanging rod 32, and a fitting fan plate 33. The hanging rod 32 is installed at the bottom of the curved tube 31. The curved tube 31 is connected to the dispensing head 13 but not to the hanging rod 32. The bottom of the curved tube 31 has an outlet 301 facing the inner wall of the packaging tank 400. The lubricating concentrate flowing into the curved tube 31 from the dispensing head 13 can flow out from the outlet 301. Each hanging rod 32 is provided with a pair of fitting fan plates 33 on its outside. The fitting fan plates 33 can rotate around the central axis of the hanging rod 32 by the drive of the linkage ring assembly 34.

[0028] The hanging rods 32 are made of a material that can be attracted by magnetic force, and each hanging rod 32 itself is not magnetic to avoid mutual attraction. Before contacting the bottom of the packaging can 400, the hanging rods 32 will straighten the curved tubes 31 by their own weight. The diameter of the ring formed by each of the curved tubes 31 is smaller than the opening of the packaging can 400, so that the hanging rods 32 can smoothly enter the packaging can 400 vertically. After the hanging rods 32 contact the bottom of the packaging can 400, the liquid dispensing head 13 continues to move downward, and the curved tubes 31 will bend. After that, the electromagnetic suction head 22 is energized and generates magnetism to attract each hanging rod 32 to the side wall of the packaging can 400.

[0029] Under normal conditions, the bonding fan plate 33 is driven by the linkage ring assembly 34 and keeps pointing towards the center of the circle formed by the curved tube 31. When the linkage ring assembly 34 is magnetically attracted by the electromagnetic suction head 22, it will drive the bonding fan plate 33 to turn to the side wall of the packaging can 400 and adhere to the inner side wall of the packaging can 400.

[0030] The bonding fan plate 33 includes a side sealing plate 331, an inner extension block 332, and a top sealing plate 333. The side sealing plate 331 is connected to the linkage ring assembly 34. One side of the side sealing plate 331 is tightly attached to the outer peripheral wall of the hanging rod 32, and the other side can be tightly attached to the inner side wall of the packaging can 400 after being flipped by magnetic force. The upper end of the side sealing plate 331 extends above the liquid outlet 301. The top sealing plate 333 is installed on the upper end of the side sealing plate 331, and the top sealing plate 333 has an arc edge that can fit against the inner side wall of the packaging can 400 so that after flipping... The side sealing plate 331 and the inner wall of the packaging tank 400 form an open space at the lower end for the lubricating concentrate to flow downwards. After the hanging rod 32 moves toward the side wall of the packaging tank 400, the magnetic frame 2 will rise by three to five centimeters to drive the hanging rod 32 to move upwards to open the outlet of the lubricating concentrate. The inner extension block 332 is set inside the side sealing plate 331. When the side sealing plate 331 is close to the inner wall of the packaging tank 400, there is a gap between the inner extension block 332 and the inner wall of the packaging tank 400, and the top of the inner extension block 332 is below the liquid outlet 301.

[0031] The lubricating concentrate flowing out of the outlet 301 at high speed is buffered in the space above the inner extension block 332 and then squeezed into the relatively wide and narrow space between the inner extension block 332 and the inner wall of the packaging can 400. With the inner wall of the packaging can 400 as the guiding surface, it can flow down at high speed and smoothly, greatly reducing the generation of bubbles.

[0032] Example 2

[0033] Reference Figure 1-4 The difference between this embodiment and embodiment 1 is that the outer peripheral wall of the hanging rod 32 is provided with a limiting ring groove 302 at the location of the linkage ring assembly 34, and the linkage ring assembly 34 is provided with one at the top and one at the bottom, which are respectively connected to the two fitting fan plates 33.

[0034] The linkage ring assembly 34 includes an outer ring 341, an annular hydraulic plug 342, an annular hydraulic cylinder 343, a central hydraulic cylinder 344, a magnetic hydraulic plug 345, and a return spring 346. The outer ring 341 is installed in the limiting ring groove 302. The outer ring 341 can rotate axially under the restriction of the limiting ring groove 302, but cannot move vertically. The inner side of the outer ring 341 has a protrusion that fits against the inner wall of the limiting ring groove 302 to form a gap between the outer ring 341 and the inner wall of the limiting ring groove 302 to accommodate the annular hydraulic cylinder 343. One end of the magnetic hydraulic plug 345 is connected to the protrusion on the inner side of the outer ring 341, and the other end is inserted into the annular hydraulic cylinder 343.

[0035] The hanging rod 32 is hollow inside to accommodate the central hydraulic cylinder 344, which is connected to the annular hydraulic cylinder 343. The magnetic hydraulic plug 345 is disposed inside the central hydraulic cylinder 344. A return spring 346 is installed between the magnetic hydraulic plug 345 and the inner wall of the hanging rod 32. Under normal conditions, the return spring 346 keeps the magnetic hydraulic plug 345 away from the inner wall of the packaging can 400. At this time, the hydraulic fluid is drawn into the central hydraulic cylinder 344. The annular hydraulic plug 342 has the longest length inserted into the annular hydraulic cylinder 343. The magnetic hydraulic plug 345 can be attracted by the magnetic force outside the side wall of the packaging can 400 to draw the hydraulic fluid into the annular hydraulic cylinder 343, thereby squeezing the annular hydraulic plug 342 out of the annular hydraulic cylinder 343 and pushing the outer ring 341 to rotate axially.

[0036] Preferably, the magnetic hydraulic plug 345 is connected to the outer abutment ring 347 via a linkage frame 348, and the return spring 346 is sleeved and installed outside the central hydraulic cylinder 344 and connected to the outer abutment ring 347, which is also located outside the central hydraulic cylinder 344. The return spring 346 drives the magnetic hydraulic plug 345 to move by pushing the outer abutment ring 347 to move, so as to make the most of the central space of the hanging rod 32.
