[0002] In a reciprocating medicine cutter, the movable shaft undergoes high-frequency reciprocating motion (approximately 300 times per minute). Wear or obstructed movement can occur when the movable shaft mates with the guide bushing. Lubrication of the assembly gap between the movable shaft and the guide bushing is necessary to reduce wear and ensure the service life of the movable shaft. Common lubrication methods often fail to accurately lubricate the assembly gap between the movable shaft and the guide bushing, resulting in insufficient lubrication at the movable shaft location, which can still lead to wear and compromise the effectiveness of lubrication.

[0008] A lubrication pump is provided with an injection pipe, which is inserted into the second injection hole so that the lubrication pump is in fluid communication with the movable channel through the injection pipe.

[0009] In one possible embodiment of the present invention, the guide assembly includes a hollow guide sleeve and a pressure cap.

[0013] In one possible embodiment of this utility model, the center line of the second injection hole is collinear with the center line of the first injection hole.

[0014] In one possible embodiment of this utility model, the diameter of the second injection hole gradually decreases in the direction toward the first injection hole, and the diameter of the second injection hole is smallest at the position where the second injection hole connects with the first injection hole.

[0030] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0031] In related technologies, the movable shaft in a reciprocating medicine cutter undergoes high-frequency reciprocating motion (approximately 300 times per minute). Wear or obstructed movement can occur when the movable shaft mates with the guide copper sleeve. Lubrication of the assembly gap between the movable shaft and the guide copper sleeve is necessary to reduce wear and ensure the service life of the movable shaft. However, common lubrication methods are insufficient to accurately lubricate the assembly gap between the movable shaft and the guide copper sleeve. Insufficient lubricant at the movable shaft location can lead to continued wear, and the lubrication effect cannot be guaranteed.

[0032] To solve the above problems, refer to Figure 1 As shown, an embodiment of this application provides a lubrication device 100, which includes a guide assembly 130, a mounting base 120, a movable shaft 140, and a lubrication pump 150.

[0033] Specifically, in combination Figure 1 and Figure 2 As shown, the guide assembly 130 is provided with a first injection hole 1311 and a movable channel 133. The first injection hole 1311 is connected to the movable channel 133. The mounting base 120 is sleeved on the guide assembly 130. The mounting base 120 is provided with a second injection hole 121. The second injection hole 121 is oriented towards the first injection hole 1311. Lubricating fluid enters the second injection hole 121 and the first injection hole 1311 sequentially through the injection pipe 151, so that the lubricating fluid enters the position of the movable channel 133, thereby lubricating the assembly gap between the movable shaft 140 and the guide assembly 130.

[0034] The lubrication device 100 also includes a frame 110, and a mounting base 120 is mounted on the frame 110. The frame 110 is used to support and fix the mounting base 120.

[0035] In this embodiment, the movable shaft 140 passes through the movable channel 133 and can reciprocate relative to the guide assembly 130. The movable shaft 140 completes mechanical transmission through reciprocating motion. The lubrication pump 150 is provided with an injection pipe 151, which is inserted into the second injection hole 121 so that the lubrication pump 150 is in fluid communication with the movable channel 133 through the injection pipe 151. Correspondingly, the movable shaft 140 passes through the movable channel 133 and reciprocates relative to the guide assembly 130. The guide assembly 130 guides and regulates the reciprocating motion of the movable shaft 140. The lubricant lubricates the assembly gap between the movable shaft 140 and the guide assembly 130, and the lubricant is introduced into the assembly gap between the two more accurately. Compared with the oil cup, the lubrication pump 150 is used to control the pumping volume and pumping interval of the lubricant, so as to control the flow rate of the lubricant, reduce the wear of the movable shaft 140, improve the lubrication effect, and ensure the relative motion accuracy of the movable shaft 140.

[0036] The type of lubricant can be mineral oil or synthetic oil, etc., and it is adjusted and selected according to the operating conditions of the equipment to reduce wear, reduce friction loss, and extend the service life of the moving shaft 140. The flow rate or pressure is dynamically adjusted according to the operating conditions, for example, the fluid supply is reduced or increased according to the movement speed of the moving shaft 140.

[0037] It is understandable that in a linear reciprocating medicine cutter, the movable shaft 140 performs high-frequency reciprocating motion (approximately 300 times per minute) within the guide assembly 130. The clearance between the guide assembly 130 and the movable shaft 140 directly affects the normal operation of the medicine cutter's blade holder. In particular, the lubrication condition of the movable shaft 140 has a significant impact on the lifespan and cutting accuracy of the medicine cutter.

[0038] refer to Figure 1 and Figure 2 As shown, the lubrication device 100 has a first direction X and a second direction Y, wherein the first direction X and the second direction Y are arranged perpendicularly to each other. For example, the first direction X refers to the height direction of the lubrication device 100, and the second direction Y refers to the length direction of the lubrication device 100. It is understood that the above definitions are only for ease of understanding the relative positional relationships of the various parts in the lubrication device 100 and should not be construed as limitations on this application.

[0039] In one embodiment, optionally, the guide assembly 130 includes a hollow guide sleeve 131 and a pressure cap 132. The pressure cap 132 covers the end of the mounting base 120 and abuts against the guide sleeve 131, together defining the movable channel 133. Accordingly, the guide sleeve 131 and the pressure cap 132 jointly guide and regulate the relative movement path of the movable shaft 140. The movable shaft 140 passes through the guide sleeve 131 and can reciprocate relative to the guide sleeve 131. The pressure cap 132 acts as a seal for the mounting base 120, preventing excessive leakage of lubricant from the guide sleeve 131 and preventing foreign objects from entering the guide sleeve 131, thus preventing blockage and affecting the movement path of the movable shaft 140. This provides a better technical effect.

[0040] There are two pressure caps 132. Along the first direction X, the two pressure caps 132 are located at opposite ends of the guide sleeve 131. The two pressure caps 132 are installed at opposite ends of the guide sleeve 131 to provide a certain sealing effect for the hollow structure of the guide sleeve 131.

[0041] In one embodiment, alternatively, referencing Figure 1 and Figure 2 As shown, the guide sleeve 131 has a first injection hole 1311, which is located between the two pressure caps 132. The centerline of the first injection hole 1311 is perpendicular to the centerline of the movable channel 133. Correspondingly, the centerline of the movable channel 133 is the first direction X, and the centerline of the first injection hole 1311 is the second direction Y. The first injection hole 1311 is connected to the movable channel 133, and the lubricant can enter the movable channel 133 through the first injection hole 1311 of the guide sleeve 131, avoiding the uneven lubrication caused by the traditional axial method of adding lubricant, thereby improving the lubrication effect.

[0042] In one embodiment, the lubrication device 100 may optionally include a control component 160, which is electrically connected to the lubrication pump 150. The control component 160 is used to control the operation of the lubrication pump 150, which is an electronically controlled pump. The lubrication cycle and lubrication amount can be set according to the actual working frequency of the cutting machine to achieve automated control. The output parameters are dynamically adjusted by sensors (temperature, pressure, speed) and the control component 160, which has a high degree of intelligence, ensures the stability of the equipment, and reduces the situation of excessive or insufficient lubrication caused by traditional lubrication methods. The lubrication is pumped into the guide sleeve 131 through the injection pipe 151 to achieve the lubrication effect between the guide sleeve 131 and the movable shaft 140.

[0043] In summary, the movable shaft 140 of the lubrication device 100 passes through the movable channel 133 and reciprocates relative to the guide assembly 130. The lubricant enters the second injection hole 121 and the first injection hole 1311 sequentially through the injection pipe 151, allowing the lubricant to enter the position of the movable channel 133, thereby lubricating the assembly gap between the movable shaft 140 and the guide assembly 130. The lubricant is introduced into the assembly gap between the two more accurately. Compared with the oil cup, which uses a lubrication pump 150 to control the pumping volume and pumping interval of the lubricant, it is easier to control the flow rate of the lubricant, reduce the wear of the movable shaft 140, improve the lubrication effect, and ensure the relative motion accuracy of the movable shaft 140.

[0044] refer to Figure 1 As shown, an embodiment of this application provides another lubrication device 100, which includes a guide assembly 130, a mounting base 120, a movable shaft 140, and a lubrication pump 150.

[0045] Specifically, in combination Figure 1 and Figure 2 As shown, the guide assembly 130 is provided with a first injection hole 1311 and a movable channel 133. The first injection hole 1311 is connected to the movable channel 133. The mounting base 120 is sleeved on the guide assembly 130 and is provided with a second injection hole 121. The second injection hole 121 is positioned facing the first injection hole 1311. The movable shaft 140 passes through the movable channel 133 and can reciprocate relative to the guide assembly 130. The lubrication pump 150 is provided with an injection pipe 151, which is inserted into the second injection hole 121 so that the lubrication pump 150 is connected to the movable channel 133 through the injection pipe 151. The fluid is connected to channel 133. Correspondingly, the movable shaft 140 passes through the movable channel 133 and reciprocates relative to the guide assembly 130. The lubricant enters the second injection hole 121 and the first injection hole 1311 in sequence through the injection pipe 151, so that the lubricant enters the position of the movable channel 133, thereby lubricating the assembly gap between the movable shaft 140 and the guide assembly 130. The lubricant is introduced into the assembly gap between the two more accurately. Compared with the oil cup, the lubrication pump 150 is used to control the pumping volume and pumping interval of the lubricant, so as to control the flow rate of the lubricant, reduce the wear of the movable shaft 140, improve the lubrication effect, and ensure the relative motion accuracy of the movable shaft 140.

[0046] In one embodiment, the guide assembly 130 optionally includes a hollow guide sleeve 131 and a pressure cap 132. The pressure cap 132 covers the end of the mounting base 120 and abuts against the guide sleeve 131, together defining the movable channel 133. Correspondingly, the movable shaft 140 passes through the guide sleeve 131 and can reciprocate relative to the guide sleeve 131. The pressure cap 132 acts as a seal for the mounting base 120, preventing excessive leakage of lubricating fluid in the guide sleeve 131 and sealing the guide sleeve 131 to prevent foreign objects from entering and causing blockages in the guide sleeve 131, thus affecting the movement path of the movable shaft 140. This provides a better technical effect.

[0047] For example, the guide sleeve 131 can be made of copper alloy, which has high wear resistance, low coefficient of friction and good thermal conductivity, so as to guide, support, reduce friction and position the movable shaft 140.

[0048] Optionally, the cover 132 and the mounting base 120 form a snap-fit ​​structure. A limiting step is provided at the position of the mounting base 120. The cover 132 is snap-fitted with and fixed to the limiting step. The limiting step is used to limit the lateral displacement of the cover 132.

[0049] Furthermore, such as Figure 2 As shown, the guide assembly 130 further includes a seal 134. The gland 132 defines an annular groove 1321, and the seal 134 is disposed within the annular groove 1321 and sleeved on the movable shaft 140. The seal 134 provides a better seal when the gland 132 is assembled on the mounting base 120, preventing external residue and dust from entering the guide sleeve 131. For example, the seal 134 is a sealing ring, which can be made of silicone, elastic rubber, etc., and has a certain elasticity to reduce the gap between the sealing ring and the movable shaft 140, without hindering or affecting the reciprocating movement of the movable shaft 140.

[0050] In addition, there are two pressure caps 132. Along the first direction X, the two pressure caps 132 are located at opposite ends of the guide sleeve 131. The two pressure caps 132 are installed at opposite ends of the guide sleeve 131, which plays a certain sealing role for the hollow structure of the guide sleeve 131.

[0051] In one embodiment, alternatively, referencing Figure 1 and Figure 2As shown, the guide sleeve 131 has a first injection hole 1311, which is located between the two pressure caps 132. The center line of the first injection hole 1311 is perpendicular to the center line of the movable channel 133. Correspondingly, the center line of the movable channel 133 is the first direction X, and the center line of the first injection hole 1311 is the second direction Y. The first injection hole 1311 is connected to the movable channel 133, and the lubricant can enter the movable channel 133 through the first injection hole 1311 of the guide sleeve 131, avoiding the uneven lubrication caused by the traditional axial method of adding lubricant, thereby improving the lubrication effect.

[0052] Optionally, such as Figure 1 As shown, the center line of the second injection hole 121 is collinear with the center line of the first injection hole 1311. The second injection hole 121 of the guide seat is set corresponding to the first injection hole 1311 of the guide sleeve 131, so that the lubricant enters into the movable channel 133 through the second injection hole 121 and the first injection hole 1311 in sequence, which lubricates the movable shaft 140 of the movable channel 133, reduces the wear of the movable shaft 140 in reciprocating motion, and improves the service life of the movable shaft 140.

[0053] Optionally, such as Figure 2 As shown, the diameter of the second injection hole 121 gradually decreases in the direction towards the first injection hole 1311. The diameter of the second injection hole 121 is smallest at the position where the second injection hole 121 connects with the first injection hole 1311. This is to accelerate the flow speed of the lubricant through the docking area, reduce the possibility of lubricant stagnation in the second injection hole 121, avoid the risk of blockage caused by lubricant accumulation, and form a local pressure increase zone at the docking end near the first injection hole 1311, thereby enhancing the impact of the lubricant on the surface of the movable shaft 140.

[0054] Furthermore, the second injection hole 121 has a tapered hole structure. The tapered hole structure of the second injection hole 121 increases the flow rate of lubricant through the second injection hole 121, reduces the adhesion of lubricant to the hole wall, and avoids contamination or blockage caused by residue. For example, the injection pipe 151 of the lubrication pump 150 is provided with an adapter, which is inserted into the second injection hole 121 of the guide seat. The diameter of the adapter is larger than the diameter of the first injection hole 1311.

[0055] In one embodiment, the lubrication device 100 may optionally include a control component 160, which is electrically connected to the lubrication pump 150. The control component 160 is used to control the operation of the lubrication pump 150. It can set the lubrication cycle and lubrication amount according to the actual working frequency of the cutting machine, realize automated control, ensure the stability of the equipment, reduce the situation of insufficient or excessive lubrication caused by traditional methods of adding lubricating fluid, and allow the lubricating fluid to be pumped into the guide sleeve 131 through the injection pipe 151 to achieve the lubrication effect between the guide sleeve 131 and the movable shaft 140, thereby improving the lubrication effect.

[0056] An embodiment of this utility model also provides a medicine cutting machine, which includes the lubrication device 100 in the above embodiment. The medicine cutting machine including the lubrication device 100 has all the beneficial effects of the lubrication device 100, which will not be described in detail here.

[0057] A medicine cutting machine can be a reciprocating medicine cutting machine. A reciprocating medicine cutting machine is an automated slicing device used in industries such as traditional Chinese medicine and agriculture. It is mainly used to cut raw materials such as medicinal materials into slices, strips or blocks according to a set thickness. Its characteristic is that it uses a reciprocating motion structure to drive the cutter (or cutter holder) to perform periodic cutting operations. Of course, there are no specific restrictions on the type of medicine cutting machine.

[0058] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limitations; therefore, other examples of exemplary embodiments may have different values.

[0059] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
