Description

Technical Field

[0001] The utility model relates to a peristaltic pump, in particular to an industrial improved peristaltic pump capable of accurately supplying fluid flow and a lubricating device having the same. Background Art

[0002] For processing machines such as punching machines or metal cutting machines, lubricating oil is required during processing to prevent overheating and damage to the tools or workpieces, and to improve processing quality.

[0003] The conventional lubrication method is to use a solenoid valve to control the lubricating oil switch, and then use a flow controller to control the flow rate.

[0004] However, the conventional method is difficult and imprecise in controlling the amount of lubricating oil. If too much lubricating oil is supplied, it will be wasted, and if the lubricating oil is insufficient, the lubrication effect cannot be fully exerted, and even damage to the tool or workpiece is caused, and the processing quality is affected.

[0005] Therefore, how to develop an "industrial improved peristaltic pump and lubrication device having the same" that can accurately supply fluid flow is an urgent issue to be solved by people in the relevant technical field. Utility Model Content

DETAILED DESCRIPTION

[0039] See also Figures 1 to 3 As shown, the present invention provides an improved industrial peristaltic pump 100 , which includes a body 10 , a wheel assembly 20 , a cover 30 and a tube 40 .

[0040] The material of the main body 10 , the wheel set 20 and the cover 30 is preferably a hard metal material, such as stainless steel or cast iron.

[0041] The tube 40 is made of flexible material, such as soft plastic.

[0042] The wheel set 20 includes a driving wheel 21 and six driven wheels 22A-22F.

[0043] It must be noted that the number of the passive wheels of the present invention is an integer multiple of six, and is not limited to six. For example, it can be twelve, eighteen, and so on.

[0044] The driving wheel 21 is pivotally mounted on the body 10 about a rotation axis C21. The driving wheel 21 can be driven to rotate about the rotation axis C21.

[0045] The method for driving the driving wheel 21 to rotate is not limited, and for example, the driving wheel 21 may be driven to rotate by a servo motor.

[0046] The driven wheels 22A-22F are equidistantly pivoted around the rotation axis C21 on the driving wheel 21. The axes C22A-C22F of the driven wheels 22A-22F are parallel to the rotation axis C21, and the distances D1-D6 between the driven wheels 22A-22F and the rotation axis C21 are equal.

[0047] The diameter D22 of the driven wheels 22A-22F is smaller than the diameter D21 of the driving wheel 21. The outer edge of each driven wheel 22A-22F protrudes beyond the outer edge of the driving wheel 21.

[0048] The cover 30 has a concave surface 31 , the center of curvature of which is parallel to the rotation axis C21 . A first concave portion 32 , a pressing portion 33 , and a second concave portion 34 are sequentially formed along the curvature of the concave surface 31 .

[0049] The cover 30 is disposed on the main body 10 and partially covers the plurality of driven wheels 22A-22B, 22F. The pressing portion 33 contacts and compresses the tube 40. The space formed by the first and second recesses 32, 34 and the driven wheels 22B, 22F allows the tube 40 to pass through without compressing the tube 40.

[0050] The cover 30 is pivotally mounted on the main body 10 . The cover 30 can be turned relative to the wheel assembly 20 around the pivot axis C30 .

[0051] A fluid (not shown in the figure) flows inside the tube body 40 . The fluid may be, for example, lubricating oil, depending on actual needs.

[0052] The tube body 40 is disposed between the cover body 30 and the wheel assembly 20 , and a portion of the tube body located between the extrusion portion 33 and the wheel assembly 20 is squeezed and deformed.

[0053] See also Figure 4 and Figure 5 As shown, when the driving wheel 21 is driven to rotate, it can drive all the driven wheels 22A to 22F to rotate together. When any driven wheel 22A rotates to the extrusion portion 33, the outer edge of the driven wheel 22A and the extrusion portion 33 squeeze the tube body 40 again, so that the inner wall of the tube body 40 fits together and blocks the flow of the fluid L. Figure 4 When the driven wheel 22A passes through the extrusion portion 33 and releases the tube 40, the fluid L can circulate again, as shown in FIG. Figure 5 shown.

[0054] Due to the above structural characteristics, when the driven wheels 22A-22F rotate sequentially to the extrusion portion 33 and pass through the extrusion portion 33, the fluid L can be controlled to flow out of the tube 40 at intervals at a certain flow rate.

[0055] See also Figure 6 As shown, the utility model provides a Figure 1 The lubrication device 200 of the industrial improved peristaltic pump 100 shown includes a machine base 202 and a fluid box 204 .

[0056] The industrial improved peristaltic pump 100 is installed on a machine platform 202. A servo motor (not shown) for driving the driving wheel 21 can be installed in the machine platform 202.

[0057] A fluid box 204 is mounted on top of the machine 202. The fluid box 204 contains a fluid L. A tube 40 is disposed between the wheel assembly 20 and the cover 30. A first end 41 of the tube 40 extends into the fluid L, while an opposite second end 42 of the tube 40 extends outside the wheel assembly 20.

[0058] A level H41 of the first end 41 is higher than a level H42 of the second end 42 .

[0059] A weight 43 is provided at the first end 41 . The weight of the weight 43 is greater than the buoyancy of the fluid L, so that the first end 41 has a certain weight and sinks to the bottom of the fluid box 204 .

[0060] The machine 202 is provided with a control panel 206 electrically connected to the industrial improved peristaltic pump 100 , allowing the user to control the operation of the lubrication device 200 .

[0061] A plurality of buffer elements 208 are disposed at the bottom of the machine platform 202 to provide shock absorption for the lubricating device 200. The buffer elements 208 may be made of rubber, for example.

[0062] A sensor 210 is provided between the fluid box 204 and the industrial improved peristaltic pump 100. The sensor 210 may be, for example, a non-contact liquid level detection sensor.

[0063] The sensor 210 senses whether the fluid L is flowing in the tube 40. When the sensor 210 senses that the fluid L is not flowing in the tube 40, an alarm (not shown) is triggered to sound an alarm or force the lubricating device 200 to shut down.

[0064] See also Figure 3 、 Figure 4 and Figure 6 As shown, by virtue of the structural characteristics of the industrial improved peristaltic pump 100 provided by the present invention, when the driven wheels 22A to 22F rotate sequentially to the extrusion portion 33 and pass through, a siphon effect can be formed on the fluid L in the fluid box 204, thereby controlling the fluid L to flow out of the tube 40 at intervals at a certain flow rate, for example, one drop every 18 seconds.

[0065] In summary, the improved industrial peristaltic pump and lubrication device provided by the present invention, utilizing a specially designed cover structure in conjunction with a wheel assembly, can achieve the goal of precisely supplying fluid flow. This invention truly combines practicality and functionality.

[0066] Although the present invention has been disclosed above by the embodiments, they are not intended to limit the present invention. Any person skilled in the art with ordinary knowledge in the relevant technical field should be able to make slight changes and modifications without departing from the spirit and scope of the present invention, and they should still fall within the scope of protection of the present invention.
