Description

Technical Field

[0001] This utility model relates to the field of ceramic filling pump technology, specifically an economical short-stroke ceramic filling pump. Background Technology

[0002] Ceramic filling pumps, also known as ceramic metering pumps, are devices used in the precise metering and filling of liquids. They are made primarily of ceramic materials because ceramics possess high hardness, strong wear resistance, and excellent chemical stability, enabling them to resist the erosion of various corrosive liquids, effectively extending the equipment's service life and ensuring the accuracy and stability of metering.

[0003] During operation, ceramic filling pumps precisely control changes in the pump chamber volume to achieve quantitative extraction and delivery of liquids. When the pump chamber volume increases, liquid flows into the pump chamber under external pressure; when the pump chamber volume decreases, liquid is squeezed out of the pump chamber, thus completing one filling or metering process. This precise volume control allows ceramic filling pumps to meet the stringent requirements of high-precision liquid metering and filling in industries such as pharmaceuticals, food, and chemicals. For example, in the pharmaceutical industry, precise control of the filling volume of drugs is required to ensure accurate dosage and stable efficacy; in the food industry, precise metering is also needed for the filling of beverages, sauces, etc., to avoid overfilling or underfilling. Ceramic filling pumps can meet these needs with their high-precision metering characteristics.

[0004] The existing ceramic metering pumps are not economically and rationally designed. The pump rod and related components are too long, which not only increases the manufacturing cost, but also makes them prone to breakage due to stress during use, affecting the normal operation of the equipment and resulting in low reliability. At the same time, once the operating parts of the existing metering pumps are deformed or damaged, the overall disassembly and assembly process is complicated and the replacement is inconvenient, which consumes a lot of time and manpower costs and is not conducive to daily maintenance and use.

[0030] Example 1

[0031] Combination Figures 1 to 4 An economical short-stroke ceramic filling pump includes a metering pump body 3, a pump rod 4 fixedly connected to the top of the metering pump body 3, a protrusion 41 fixedly connected to the front side of the pump rod 4, a rocker mechanism 1 set on the front side of the protrusion 41, and a positioning mechanism 2 set on the right side of the rocker mechanism 1.

A sleeve 1102 is fitted around the outer ring of the prism rod 1101, and a rocker arm 1103 is fixedly connected to the front side of the sleeve 1102. The locking assembly 12 includes an insert 1201, which is locked inside the top of the sleeve 1102. A grip 1202 is fixedly connected to the top of the insert 1201, and a locking plate 1203 is fixedly connected to the bottom of the insert 1201. The clamping plate 1203 is clamped inside the sleeve 1102 and the rib 1101. The outer ring of the clamping plate 1203 is fitted with a sleeve frame 1204, which is fixedly connected to the bottom of the sleeve 1102. The locking assembly 13 includes a bolt 1301, which is clamped inside the clamping plate 1203 and the sleeve frame 1204. The outer ring of the bolt 1301 is threadedly connected to a fixing screw 1302, which is fixedly connected to the left side of the sleeve frame 1204.

[0034] Furthermore, by setting short protrusions 41, this device saves costs while shortening the length of the thin rod, making the pump rod 4 less prone to breakage, thus improving the economy and reliability of the equipment. At the same time, the staff can disassemble and assemble the rocker arm 1103 as needed without affecting the normal use of the metering pump body 3. The rocker arm 1103 can also be directly replaced if it is deformed or damaged. The operation is simple and convenient for the staff to use.

[0035] Example 2

[0036] See Figures 1 to 6 Furthermore, based on Embodiment 1, the positioning mechanism 2 includes a support component 21, a reset component 22, a positioning component 23, and a disassembly component 24. The support component 21 is located on the right side of the rocker arm assembly 11, the reset component 22 is located inside the support component 21, the positioning component 23 is located at the bottom of the reset component 22, and the disassembly component 24 is located at the top of the reset component 22.

[0037] Support assembly 21 includes a fixed cylinder 2101, which is located on the right side of sleeve 1102. A fixed rod 2102 is fixedly connected to the left side of the fixed cylinder 2101, and the fixed rod 2102 is fixedly connected to the right side of sleeve 1102. Reset assembly 22 includes a sliding cylinder 2201, which is slidably connected inside the fixed cylinder 2101. A compression spring 2202 is fixedly connected to the top of the sliding cylinder 2201. Positioning assembly 23 includes a locking rod 2301, which is fixedly... The bottom of the slide cylinder 2201 is fixedly connected to the locking rod 2301. The outer ring of the locking rod 2301 is fitted with a sleeve 2302. The left side of the sleeve 2302 is fixedly connected to a rotating piece 2303. The rotating piece 2303 is rotatably connected to the right side of the bolt 1301. The disassembly assembly 24 includes a telescopic slide rod 2401. The telescopic slide rod 2401 is fixedly connected to the top of the slide cylinder 2201. The telescopic slide rod 2401 is slidably connected to the top of the fixed cylinder 2101. The top of the telescopic slide rod 2401 is fixedly connected to a pull rod 2402.

[0038] Furthermore, the locking rod 2301 engages within the sleeve 2302 to limit the bolt 1301, preventing it from detaching after installation. This ensures the locking effect of the locking plate 1203 on the rib 1101 and sleeve 1102, increasing the stability of the rocker arm 1103 after installation. Moreover, workers only need to pull the lever 2402 upwards to release the connection between the locking rod 2301 and the sleeve 2302, without affecting the disassembly of the rocker arm 1103.

[0039] In actual operation, when this device is used, when the metering pump body 3 needs to be used, the operator first snaps the sleeve 1102 onto the outer ring of the rib 1101, and then inserts the clamping plate 1203 into the sleeve 1102 and the rib 1101, so that the insert 1201 snaps onto the top of the sleeve 1102.

[0040] Next, the staff pulls the lever 2402 upward. The upward movement of the lever 2402 drives the locking lever 2301 upward through the telescopic slide rod 2401 and the slide cylinder 2201. The locking lever 2301 moves upward and retracts into the fixed cylinder 2101. Then, the staff inserts the bolt 1301 into the locking plate 1203 and the sleeve 1204, so that the bolt 1301 contacts the fixed screw cylinder 1302. Then, the bolt 1301 is rotated. The bolt 1301 rotates to the left within the inner ring of the fixed screw cylinder 1302 until the bolt 1301 can no longer rotate. At this point, the installation of the rocker arm 1103 is completed.

[0041] Then, the staff twists the sleeve 2302 to align it with the locking rod 2301. Then, the staff releases the pull on the pull rod 2402. At this time, the slide cylinder 2201 moves the locking rod 2301 downward under the action of the compression spring 2202. The locking rod 2301 moves downward and locks into the sleeve 2302. At this time, the limiting treatment of bolt 1301 is completed.

[0042] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
