Description

Technical Field

[0001] This disclosure relates to a precision lubrication system for the conveyor chain of a tinplate drying oven, belonging to the field of chain lubrication technology. Background Technology

[0002] The printing oven drive system is a key piece of equipment used in the printing industry, especially in the printing process of metal packaging materials (such as beverage cans, food cans, etc.) to dry ink or coatings. The main function of this system is to transport the printed metal sheets (usually aluminum or steel) into the drying oven via a conveyor belt in a high-temperature environment, ensuring that the ink or coating can be fully dried and cured within a set time.

[0003] The transmission system of the tinplate drying oven mainly uses chain drive. To reduce mechanical wear and noise, lubricants such as lubricating oil and grease are usually added. However, the existence of automatic lubricant adding devices cannot precisely add lubricant according to the process and actual conditions, resulting in suboptimal lubrication. This leads to insufficient or excessive lubrication, reducing chain lifespan, and potentially contaminating the produced products and affecting production efficiency. Utility Model Content

[0004] To overcome the above problems, this disclosure provides a precision lubrication system for the conveyor chain of a tinplate drying oven.

[0009] Origin proximity switch, used to locate the starting position of the conveyor chain;

[0010] The speed increaser is connected to the rotation output shaft of the chain position acquisition gear and amplifies the rotation amount of the chain position acquisition gear;

[0011] Rotate the measuring unit to record the amount of rotation at the output of the speed increaser;

[0012] A lubrication unit is used to lubricate the conveyor chain;

[0013] The control unit, together with the gear tooth proximity switch, the origin proximity switch and the rotation measurement unit, controls the lubrication unit to apply lubricating oil or lubricant to the conveyor chain.

[0014] Furthermore, the gear tooth proximity switch is a pulse sensing switch, which calculates the number of teeth the gear has rotated by acquiring the chain position through pulse signals.

[0015] Furthermore, the rotation measurement unit includes an encoder.

[0016] Furthermore, the lubrication unit includes a lubrication valve body, which is controlled by a high-speed solenoid valve.

Obviously, the described embodiments are only some, not all, of the embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the described embodiments of this disclosure without creative effort are within the scope of protection of this disclosure.

Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect.

To keep the following description of the embodiments of this disclosure clear and concise, detailed descriptions of some known functions and components are omitted.

[0027] The present disclosure will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0028] refer to Figure 1 A precision lubrication system for the conveyor chain of a tinplate drying oven, comprising:

[0029] Chain position acquisition gear 1 meshes with the conveyor chain, and the conveyor chain drives the chain position acquisition gear 1 to rotate when it is in motion;

[0030] The gear tooth proximity switch 2 collects the number of teeth rotated by the chain position sensor 1;

[0031] Origin proximity switch 6 is used to locate the starting position of the conveyor chain;

[0032] Speed ​​increaser 3 is connected to the rotation output shaft of the chain position acquisition gear 1 and amplifies the rotation amount of the chain position acquisition gear 1;

[0033] Rotate the measuring unit 4 to record the rotation amount at the output of the speed increaser 3;

[0034] Lubrication unit 5 is used to lubricate the conveyor chain;

[0035] The control unit is communicatively connected to the gear tooth proximity switch 2, the origin proximity switch 6, and the rotation measurement unit 4, and controls the lubrication unit 5 to apply lubricating oil or lubricant to the conveyor chain.

[0036] The system uses a tooth proximity switch 2 to collect the number of teeth rotated by the gear 1 and a point proximity switch 6 to locate the starting position of the conveyor chain. Combining these two methods, the number of teeth on the conveyor chain can be obtained.

[0037] The rising edge signal of the gear tooth proximity switch 2 is used as the start signal of the rotation measurement unit 4, thereby obtaining the signal change of the rotation measurement unit 4 when the chain position acquisition gear 1 rotates one tooth. Lubricant needs to be applied to the connection area of ​​the moving links of the conveyor chain. Based on the signal change of the rotation measurement unit 4, the working time of the lubrication unit 5 can be accurately controlled.

[0038] When the chain position acquisition gear 1 rotates one tooth, the angle it turns is too small, making it difficult to accurately acquire the rotation amount directly using the rotation measurement unit 4. Therefore, by amplifying the rotation amount of the chain position acquisition gear 1 (i.e., the motion information of the conveyor chain) through the speed increaser 3, the measurement accuracy of the rotation measurement unit 4 can be improved, facilitating precise positioning of the lubrication position.

[0039] Based on the above information, the control unit can automatically lubricate the conveyor chain in a preset manner, achieving precise and quantitative lubrication.

[0040] In one embodiment of this disclosure, the gear tooth proximity switch 2 is a pulse sensing switch, which calculates the number of teeth rotated by the chain position acquisition gear 1 through pulse signals.

[0041] In one embodiment of this disclosure, the rotation measuring unit 4 includes an encoder.

[0042] In one embodiment of this disclosure, the lubrication unit 5 includes a lubrication valve body, which is controlled by a high-speed solenoid valve.

[0043] In one embodiment of this disclosure, the control unit includes a PLC (Programmable Logic Controller). The PLC collects, processes, and controls the lubrication unit 5 to apply lubricating oil or lubricant to the conveyor chain.

[0044] In one embodiment of this disclosure, a touch screen is also included, which is communicatively connected to the PLC programmable logic controller.

[0045] refer to Figure 2 This is a schematic diagram of a module according to an embodiment of the present disclosure. The PLC programmable logic controller acquires the origin information of the conveyor chain, collects the rotation information of gear 1 and encoder data of the chain position, and controls the operation of the lubrication unit 5 through this data. The lubrication unit 5 includes an oil circuit control solenoid valve, an oil pump control solenoid valve and an oil injection valve. Interaction is achieved through an HMI touchscreen. In some embodiments, the PLC programmable logic controller also connects to equipment connection signals and pressure detection signals to ensure safe system operation.
