Technical Field

[0001] This application relates to the field of traditional Chinese medicine residue treatment technology, specifically to a laser marking device for residue bags and a residue dumping and packaging machine. Background Technology

[0002] In related technologies, there are usually two methods for handling medicinal residue after it is generated. One is to directly dump the residue into a garbage can or use a screw conveyor to send it to a waste treatment station for direct processing. The other is to wrap the medicinal slices in non-woven fabric before decoction, put the whole package into the decoction pot, and after decoction, take out the whole package of residue, keep it for a period of time, and then process it. However, a large amount of residue is easy to get confused during storage. If the residue packages are individually labeled and classified for storage, the labor cost is high. Summary of the Invention

[0003] In order to at least address one deficiency in the related technology, this application provides a laser marking device for medicinal residue and a residue dumping and packaging machine.

[0004] A laser marking device for medicinal residue bags includes a frame and a bag-pressing assembly. The laser marking assembly is mounted on the frame for laser marking of the medicinal residue bags. The bag-pressing assembly includes a movable frame and a bag-pressing part; the movable frame is slidably mounted on the frame, and the bag-pressing part is disposed on the movable frame; the movable frame is capable of moving the medicinal residue bag from the feed inlet to the laser marking assembly.

[0005] The bag-pressing part includes a bag-pressing plate, which is slidably mounted on the movable frame. When the bag-pressing plate extends away from the bag-pressing part, it can press against the dregs bag to fix the dregs bag.

[0006] Furthermore, the frame is provided with an optical axis, one end of which is located at the feed inlet of the frame, and the other end of which is located away from the feed inlet at the laser marking location.

[0007] The movable frame is equipped with a transverse cylinder to drive the movable frame to move along the optical axis.

[0008] Furthermore, at least two optical axes are arranged parallel to each other on the frame, and the moving shaft of the transverse cylinder is arranged between the two optical axes, with the moving shaft being parallel to the optical axes.

[0009] Furthermore, the mobile frame is also equipped with a gripping part, which includes a gripping cylinder and a gripping frame, with the gripping frame slidably mounted on the gripping cylinder. The gripping cylinder can drive the gripping frame to extend towards the laser marking component.

[0010] Furthermore, the gripping frame is evenly provided with multiple suction cups, and the suction cups are elastically mounted on the gripping frame.

[0011] Furthermore, the bag-pressing part also includes a bag-pressing cylinder, which is disposed on the movable frame. The bag-pressing plate is mounted on the bag-pressing cylinder, and the bag-pressing plate can be driven by the bag-pressing cylinder to slide in a direction close to or away from the dregs bag.

[0012] Furthermore, the pressure plate has a notch.

[0013] Furthermore, the frame is also provided with a limiting component, which includes an upright plate and a limiting plate. The upright plate is disposed on the frame, and the limiting plate is hinged to the upright plate. The limiting plate can abut against the side of the dregs bag away from the pressing plate.

[0014] Furthermore, the laser marking assembly includes a base and a laser, the base being disposed on the frame, and the laser being movably mounted on the base. An adjusting handwheel is also provided between the base and the laser for adjusting the relative position between the laser and the base.

[0015] This application also provides a residue packaging machine, comprising at least a packaging component and the residue bag laser marking device described in any of the above embodiments. The packaging component is disposed on the frame and is used to package the residue into residue bags; the residue bag laser marking device laser-marks the residue bags.

[0016] To achieve the above objectives, this application provides a laser marking device for medicinal residue bags, including a frame and a bag-pressing assembly. The laser marking assembly is mounted on the frame for laser marking of the medicinal residue bags. The bag-pressing assembly includes a movable frame and a bag-pressing part; the movable frame is slidably mounted on the frame, and the bag-pressing part is disposed on the movable frame; the movable frame can move the medicinal residue bag from the feed inlet to the laser marking assembly. The bag-pressing part includes a bag-pressing plate, which is slidably mounted on the movable frame, and when the bag-pressing plate extends away from the bag-pressing part, it can press against the medicinal residue bag to secure it.

[0017] Using the above technical solution, when laser marking is required on bags of medicinal residue, simply place the bag on the moving frame of the bag-pressing assembly. The moving frame carries the bag to be marked to the position of the laser marking assembly. Then, the bag-pressing plate extends towards the bag and presses it against the bag, securing it and preventing it from shaking or shifting during the laser marking process, which would affect the marking effect.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] In the description of this application, it should be noted that the terms "inner" and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0030] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "setup" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0031] This application provides a laser marking device for medicinal residue bags to solve the problems in related technologies, such as the easy confusion of large quantities of medicinal residue during storage and the high labor cost of distinguishing medicinal residue bag markings.

[0032] Please see Figure 1 , Figure 2 , Figure 5 A laser marking device for medicinal residue bags includes a frame 100 and a bag-pressing assembly 300. The frame 100 is equipped with the laser marking assembly 200 for laser marking the medicinal residue bags. The bag-pressing assembly 300 includes a movable frame 310 and a bag-pressing part 320; the movable frame 310 is slidably mounted on the frame 100, and the bag-pressing part 320 is disposed on the movable frame 310; the movable frame 310 is capable of moving the medicinal residue bag from the feed inlet to the laser marking assembly 200.

[0033] The bag pressing part 320 includes a bag pressing plate 321, which is slidably mounted on the movable frame 310. When the bag pressing plate 321 extends toward the bag pressing part 320, it can press against the dregs bag to fix the dregs bag.

[0034] Specifically, when using the laser marking device for medicinal residue bags in this embodiment, the medicinal residue bag is placed on the movable frame 310 of the bag pressing assembly 300. The movable frame 310 carries the medicinal residue bag to the laser marking assembly 200, ready for laser marking. After the medicinal residue bag is moved to the appropriate position, the bag pressing part 320 of the bag pressing assembly 300 actuates, and the bag pressing plate 321 extends towards the medicinal residue bag, pressing it against the bag to fix its position. This eliminates the shaking that occurs during the movement of the medicinal residue bag and also prevents the bag from shifting during the laser marking process, ensuring a stable and reliable laser marking process. After pressing is completed, the laser marking assembly 200 performs laser marking on the medicinal residue bag.

[0035] The laser marking device for medicinal residue bags in this embodiment can automatically laser mark medicinal residue bags, making it easy to distinguish between large quantities of bags during storage and avoiding confusion. The laser marking process also requires no manual intervention, reducing labor costs and improving the efficiency and reliability of laser marking.

[0036] In one embodiment, exemplarily, such as Figure 2 , Figure 3 As shown, a light axis 110 is provided on the frame 100. One end of the light axis 110 is located at the feed inlet of the frame 100, and the other end of the light axis 110 away from the feed inlet is located at the laser marking position. A transverse cylinder 311 is provided on the movable frame 310 to drive the movable frame 310 to move along the light axis 110. The movable frame 310 can move along the light axis 110, that is, the movable frame 310 can move back and forth between the feed inlet and the laser marking position in this embodiment along the light axis 110. Thus, when the dregs bag needs to be laser marked, it is only necessary to place the dregs bag on the movable frame 310 from the feed inlet in this embodiment.

[0037] It is understood that this embodiment can be used in conjunction with other external conveying equipment, transfer equipment, and other equipment. Specifically, after the dregs are bagged, the dregs bags can be placed directly on the conveying equipment, which will then transport the dregs bags to be laser-marked to the feed inlet. This embodiment can then perform laser marking on them, further improving the automation level of the laser marking operation of the dregs bags and enhancing the ease of use of this embodiment.

[0038] It should be noted that in this embodiment, the feed inlet can be set at any position according to actual conditions, as long as it facilitates the entry of the dregs bag into this embodiment. The optical axis 110 can be adaptively set between the feed inlet and the laser marking component 200 to transport the dregs bag.

[0039] In one embodiment, exemplarily, such as Figure 2 , Figure 3As shown, at least two optical axes 110 are arranged parallel to each other on the frame 100, and the moving shaft 312 of the transverse cylinder 311 is arranged between the two optical axes 110, with the moving shaft 312 parallel to the optical axes 110. The multiple parallel optical axes 110 can restrict the movement trajectory of the moving frame 310, preventing changes in the posture or transport trajectory of the moving frame 310 during transport, thus improving the stability of this embodiment. The moving shaft 312 of the transverse cylinder 311 is arranged between the optical axes 110, and the moving shaft 312 and the optical axes 110 jointly support the moving frame 310 and the transverse cylinder 311, improving the structural strength and durability of this embodiment.

[0040] In one embodiment, exemplarily, such as Figure 2 , Figure 3 As shown, a proximity switch 350 is also provided at one end of the optical axis 110 to detect the position of the moving frame 310. The proximity switch 350 is electrically connected to the control circuit board provided on the frame 100 in this embodiment. When using this embodiment, the automatic conveying of the dregs bag by the moving frame 310 can be achieved by detecting the position of the moving frame 310 through the proximity switch 350. Specifically, when the moving frame 310 is at a position close to the proximity switch 350 on the optical axis 110, the proximity switch 350 sends a signal. At the same time, the dregs bag is placed on the moving frame 310. After placement, the control circuit board receives the electrical signal sent by the proximity switch 350 and sends a signal to the transverse cylinder 311 that drives the moving frame 310, causing the transverse cylinder 311 to start and drive the moving frame 310 to move towards the laser marking component 200. After moving to the preset position, the proximity switch 350 sends an electrical signal to the control circuit board again, and the control circuit board then controls the transverse cylinder 311 to stop moving, so that the moving frame 310 stops at the laser marking component 200, and the laser marking component 200 performs laser marking on the dregs bag.

[0041] In one embodiment, exemplarily, such as Figure 2 , Figure 3 As shown, the movable frame 310 is also equipped with a gripping part 330, which includes a gripping cylinder 333 and a gripping frame 331. The gripping frame 331 is slidably mounted on the gripping cylinder 333. The gripping cylinder 333 can drive the gripping frame 331 to extend towards the laser marking component 200. During the movement of the movable frame 310 carrying the medicine residue bag, the gripping part 330 grips the medicine residue bag to ensure the stability of the medicine residue bag during the movement of the movable frame 310.

[0042] When the dregs bag needs to be gripped, the moving frame 310 moves to a suitable position, then the gripping cylinder 333 is activated, controlling the gripping frame 331 to extend to the dregs bag and grip and secure it. When the laser marking assembly 200 marks the dregs bag with laser, the gripping frame 331 can also adaptively adjust its extension length to ensure the dregs bag is in a suitable position. After the laser marking operation is completed, the gripping cylinder 333 actuates again, causing the gripping frame 331 to release the dregs bag, which falls to a designated position or onto a conveyor belt or other equipment for subsequent processes.

[0043] In one embodiment, exemplarily, such as Figure 2 , Figure 3 As shown, multiple suction cups 332 are evenly distributed on the gripping frame 331, and the suction cups 332 are elastically mounted on the gripping frame 331. The multiple suction cups 332 on the gripping frame 331 adsorb the outer packaging of the medicine residue bag, thus completing the gripping of the medicine residue bag by the gripping frame 331. The multiple suction cups 332 effectively improve the reliability and stability of the gripping frame 331 in gripping the medicine residue bag, preventing accidents such as the medicine residue bag falling off during laser marking.

[0044] The suction cup 332 is elastically mounted on the gripping frame 331. Specifically, the suction cup 332 has an air tube communicating with it, which is slidably mounted on the gripping frame 331. An elastic element is provided between the air tube and the gripping frame 331 to ensure that the suction cup 332 can stably contact the dregs bag. In particular, after the dregs bag contains dregs, its surface is usually irregular. If the suction cups 332 are rigidly mounted on the gripping frame 331 with the same length, when the suction cups 332 grip the dregs bag, some suction cups 332 may contact the dregs bag while others are not. In this embodiment, the suction cups 332 are elastically mounted on the gripping frame 331, ensuring that all suction cups 332 contact the dregs bag during gripping, thus improving the reliability of the gripping of the dregs bag in this embodiment.

[0045] In one embodiment, exemplarily, such as Figure 2 , Figure 3As shown, the bag-pressing unit 320 also includes a bag-pressing cylinder 323, which is mounted on the movable frame 310. A bag-pressing plate 321 is installed on the bag-pressing cylinder 323, and the bag-pressing plate 321 can be driven by the bag-pressing cylinder 323 to slide towards or away from the dregs bag. After the suction cup 332 picks up the dregs bag, before laser marking, the bag-pressing cylinder 323 can drive the bag-pressing plate 321 to extend towards the dregs bag and press it against the dregs bag, fixing its position and preventing it from shaking. This ensures a more stable and reliable laser marking operation, preventing the dregs bag from shaking during laser marking and affecting normal marking.

[0046] It should be noted that by pressing the bag with the pressure plate 321, the degree of compression of the bag with the pressure plate 321 can also be changed by the degree of extension of the pressure plate 321, thereby adjusting the position of the bag and controlling the position of the laser marking on the bag, so that the laser markings of multiple bags are in the same position, which is convenient for subsequent operators to manage the bags.

[0047] In one embodiment, exemplarily, such as Figure 2 , Figure 3 As shown, a notch 324 is provided on the bag pressing plate 321. This can reduce the overall weight of the bag pressing plate 321 or increase its area, thereby enabling the bag pressing plate 321 to better press the medicine residue bag.

[0048] For example, in this embodiment, the pressure plate 321 is configured as a rectangular frame, with a notch 324 at the center of the rectangular frame. Thus, after the pressure plate 321 abuts against the dregs bag, the points where the dregs bag contacts the rectangular frame are pressed together, ensuring that the dregs bag as a whole does not shake.

[0049] It should be noted that after the bag-pressing plate 321 is set as a rectangular frame, the laser marking component 200 can also directly laser mark the dregs bag from the notch 324 of the rectangular frame, thereby further improving the stability of the marking point on the dregs bag during the laser marking process. Of course, the bag-pressing plate 321 can also be set to different shapes such as circles or polygons according to the actual situation.

[0050] In one embodiment, exemplarily, such as Figure 4As shown, a limiting component 400 is also provided on the frame 100. The limiting component 400 includes an upright plate 410 and a limiting plate 420. The upright plate 410 is mounted on the frame 100, and the limiting plate 420 is hinged to the upright plate 410. The limiting plate 420 can abut against the side of the dregs bag away from the pressing plate 321. When the limiting component 400 is set in a suitable position, and laser marking of the dregs bag is required, the pressing plate 321 abuts against one side of the dregs bag, and the limiting plate 420 rotates to abut against the other side of the dregs bag. Through the cooperation of the pressing plate 321 and the limiting plate 420, the dregs bag is restricted, further ensuring the stability of the dregs bag during the marking process.

[0051] The limiting assembly 400 also includes a limiting cylinder 430, which is mounted on the upright plate 410 and is used to drive the limiting plate 420 to rotate, and to ensure that the limiting plate 420 can provide a suitable torque when it limits and squeezes the dregs bag.

[0052] In this embodiment, the limiting component 400 is positioned on the frame 100 near the laser marking component 200. When it is not necessary to restrict the dregs bag, the limiting plate 420 rotates to an angle parallel to the upright plate 410, or to any other angle that does not affect the normal operation of other components. When it is necessary to restrict the dregs bag, it rotates to a suitable angle, and works with the bag-pressing plate 321 to limit the dregs bag.

[0053] In one embodiment, exemplarily, such as Figure 2 , Figure 3 As shown, the mobile frame 310 is also equipped with a bag squeezing plate 322. After the dregs bag moves to the laser marking location and is restricted by the bag pressing plate 321 and the limiting plate 420, the bag squeezing plate 322 can extend according to the actual situation to squeeze the dregs bag to expel the air in the dregs bag or to compact the dregs in the dregs bag, so as to ensure the reliability of the laser marking operation and facilitate the subsequent storage or processing of the dregs bag.

[0054] In one embodiment, exemplarily, such as Figure 1 As shown, the laser marking assembly 200 includes a base 210 and a laser 220. The base 210 is mounted on the frame 100, and the laser 220 is movably mounted on the base 210. An adjusting handwheel 230 is also provided between the base 210 and the laser 220 to adjust the relative position between them. After the dregs bag is fixed, the position of the laser 220 is adjusted by the adjusting handwheel 230 until the marking point of the laser 220 is at the target position. Then, the laser 220 can be activated to laser-mark the fixed dregs bag. It is understood that the laser 220 can be any common laser 220, as long as it can perform the marking operation normally.

[0055] Please see Figure 5 This application also provides a residue packaging machine, which includes at least a packaging component 500 and a residue bag laser marking device as described in any of the above embodiments. The packaging component 500 is disposed on the frame 100 and is used to package the residue into residue bags; the residue bag laser marking device marks the residue bags with laser light.

[0056] The dregs packaging machine of this embodiment includes the laser marking device for dregs bags in any of the above embodiments, and thus possesses all the beneficial effects of the laser marking device for dregs bags, which will not be elaborated here.

[0057] In this embodiment, after the dregs are generated, they are packaged by the packaging component 500 to form dregs bags. The discharge port of the packaging component 500 is set to correspond to the inlet of this embodiment, so that the dregs bags can be sent to the mobile frame 310 and subsequent laser marking operations can be performed through the mobile frame 310. The whole process is simple and convenient and requires no manual intervention.

[0058] In this embodiment, the frame 100 is also equipped with a slag-pouring component 700 and a material-feeding component 600. Specifically, after the Chinese herbal medicine slices are decocted in the decoction pot and dregs are formed, the slag-pouring component 700 can tilt the decoction pot and pour the dregs to the material-feeding component 600. The material-feeding component 600 then guides the dregs to the packaging component 500, where they are packaged to form dregs bags. Subsequent laser marking operations are then performed, further improving the automation level of dregs marking and storage.

[0059] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0060] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
