[0045] In the present disclosure, the orientation words such as "up, down, left, right" used without the opposite description are generally defined as the direction of the drawing surface, and "inner, outer" refers to the inner and outer contours of the relevant components. In addition, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0046] In the description of the present disclosure, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, can be fixedly connected, can be detachably connected, or integrally connected; can be directly connected, or indirectly connected through an intermediate medium; can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0047] As Figures 1 to 5As shown, the present disclosure provides a discharging device for rhinestone processing equipment, which comprises a cleaning mechanism 10, a receiving hopper 20, a mounting bracket 30 and a collection box 40. The receiving hopper 20 has a receiving cavity 21, and an inlet 22 and an outlet 23 are formed on the receiving hopper 20 and communicate with the receiving cavity 21. The cleaning mechanism 10 comprises a first driving member 11, a transmission assembly 12 and a cleaning assembly 13. The cleaning assembly 13 comprises two cleaning brushes 131, which are rotatably mounted on the mounting bracket 30 and are arranged at the same horizontal interval and have a cleaning passage 132. The cleaning passage 132 is located above the receiving hopper 20, and the passage wall of the cleaning passage 132 is used to contact the outer periphery of the needle column row 51 of the clamp 50. The first driving member 11 is arranged to drive the two cleaning brushes 131 to relatively rotate on the mounting bracket 30 through the transmission assembly 12. The collection box 40 is located below the receiving hopper 20 and is used to collect the materials falling from the outlet 23.

[0048] It should be understood that the end of the needle column row 51 of the clamp 50 is bonded with a rhinestone by means of hot melt adhesive, so that the rhinestone polishing equipment can stably polish the rhinestone. After a series of polishing processes, the rhinestone needs to be cleaned from the needle column row 51 and then washed. The materials falling from the needle column row 51 can include rhinestones, hot melt adhesive, and the adhesion of rhinestones and hot melt adhesive.

[0049] Through the above technical scheme, the first driving member 11 can drive the two cleaning brushes 131 to relatively rotate through the transmission assembly 12, so that a cleaning passage 132 with continuous contact and cleaning of the outer periphery of the needle column row 51 can be formed between the two cleaning brushes 131. When the needle column row 51 is inserted into the cleaning passage 132, the cleaning brushes 131 on both sides can cooperate with each other and effectively scrape or loosen the rhinestones, hot melt adhesive and the adhesion of rhinestones and hot melt adhesive adhered to the needle column row 51. That is, the automatic cleaning process of the discharging device in the present disclosure can greatly reduce the time and complexity of manual operation, and can improve the overall production efficiency. In addition, through the arrangement of the receiving hopper 20 and the collection box 40, the materials cleaned from the needle column row 51 can fall into the receiving hopper 20 through the inlet 22 below the cleaning passage 132 and enter the collection box 40 through the outlet 23. In this way, the working area can be kept clean, and the materials can be conveniently collected and processed.

[0050] As an embodiment, as Figures 1 to 3As shown, the mounting bracket 30 comprises a bracket body 31, a first support plate 32 and a second support plate 33, the transmission assembly 12 comprises a driving sprocket 121, two driven sprockets 122, a tension sprocket 123 and a chain 124, the first support plate 32 and the second support plate 33 are oppositely arranged and connected with the bracket body 31, the two cleaning brushes 131 are located between the first support plate 32 and the second support plate 33, two ends of each cleaning brush 131 are rotatably connected to the first support plate 32 and the second support plate 33 respectively, the two driven sprockets 122 are sleeved on the ends of the corresponding cleaning brushes 131 close to the first support plate 32 respectively, the first driving member 11 is arranged on the first support plate 32, the driving end of the first driving member 11 is sleeved with the driving sprocket 121, the tension sprocket 123 is rotatably connected to the first support plate 32, the chain 124 is rotatably sleeved between the driving sprocket 121, one of the two driven sprockets 122 and the tension sprocket 123, and the other of the two driven sprockets 122 is engaged with the periphery of the chain 124, so that the rotation directions of the two driven sprockets 122 are opposite.

[0051] Among them, the tension sprocket 123 can adjust the chain 124 to maintain the proper tension of the chain 124, thereby ensuring the stability and reliability of the transmission assembly 12 during transmission.

[0052] Among them, through the cooperation between the chain 124 and the sprocket (driving sprocket 121, driven sprocket 122, tension sprocket 123), the stability of power transmission can be ensured, mechanical wear can be reduced, and the service life can be prolonged.

[0053] When the first driving member 11 is started, the driving end of the first driving member 11 can drive the driving sprocket 121 to rotate. The rotation of the driving sprocket 121 can transmit power to one of the driven sprockets 122 through the chain 124, so that the corresponding cleaning brush 131 starts to rotate. Since the other driven sprocket 122 is engaged with the periphery of the chain 124, with the movement of the chain 124, the other driven sprocket 122 can rotate in the opposite direction, thereby driving the other cleaning brush 131 to rotate in the opposite direction. The two cleaning brushes 131 rotate relative to each other, and the bristles on the two cleaning brushes 131 contact and scrape off the materials on the pin column row 51 of the clamp 50, which are collected into the collecting box 40 through the receiving hopper 20.

[0054] As an embodiment, as Figures 1 to 3As shown, the mounting bracket 30 further comprises two groups of first connecting parts 34, each group of first connecting parts 34 comprises two oppositely arranged first connecting parts 34, the two first connecting parts 34 are connected with the first support plate 32 and the second support plate 33 respectively, and the two ends of each cleaning brush 131 are rotatably connected to the corresponding first connecting parts 34, and the end of each cleaning brush 131 close to the first support plate 32 protrudes from the corresponding first connecting part 34 and is sleeved with the corresponding driven sprocket 122.

[0055] The group of first connecting parts 34 provides additional support, thereby ensuring that the cleaning brush 131 can stably rotate, and reducing wear of the cleaning brush 131 caused by vibration or imbalance.

[0056] As an embodiment, as shown in the drawings, Figure 4 As shown, the bracket body 31 comprises a bottom plate 311 and first and second side plates 312 and 313 oppositely arranged on the bottom plate 311, the first support plate is arranged on the top of the first side plate 312, and the second support plate is arranged on the top of the second side plate 313, the bottom plate 311, the first side plate 312, the first support plate, the second side plate 313, and the second support plate together define a containing space 35 for containing part of the receiving hopper 20, the bottom plate 311 is formed with a through opening 36, so that the top of the receiving hopper 20 can be inserted into the containing space 35 through the through opening 36, one end of the receiving hopper 20 is provided with a first connecting shaft 60, and the other end of the receiving hopper 20 is provided with a second connecting shaft 61, the first connecting shaft 60 is connected to the first side plate 312 away from the one end of the receiving hopper 20, and the second connecting shaft 61 is connected to the second side plate 313 away from the other end of the receiving hopper 20.

[0057] The bracket body 31 is compact in design, which can effectively utilize space and make the entire device more compact, suitable for integration into existing production lines.

[0058] The two ends of the receiving hopper 20 are connected to the two side plates respectively, which can enhance the stability of the receiving hopper 20 and reduce the shaking or displacement problems that may occur during use. That is, the stable installation of the receiving hopper 20 helps to ensure that the cleaned materials can accurately fall into the receiving hopper 20, improves the material collection efficiency, and reduces waste.

[0059] As an embodiment, as shown in the drawings, Figures 1 to 4 As shown, the discharging device further comprises a splash-proof mechanism 70 mounted on the mounting bracket 30 for collecting materials splashed from the cleaning channel 132 into the first area, and the first area is arranged as a space above the cleaning assembly 13.

[0060] When the cleaning brush 131 rotates relatively in the cleaning channel 132, the cleaning brush 131 can scrape off the material (water drop, hot melt adhesive and the adhesion of water drop and hot melt adhesive) on the pin column row 51 of the clamp 50. Due to the high-speed rotation of the cleaning brush 131, part of the material can be splashed upward under the action of centrifugal force. Therefore, by setting the splash-proof mechanism 70, the splashed material can be effectively blocked and collected, the pollution of the workshop environment caused by the splashing of the material can be reduced, the working area can be kept clean, and the good production conditions can be maintained.

[0061] As an implementation form, as shown in Figures 1 to 4 The splash-proof mechanism 70 includes two splash-proof assemblies 71, and the mounting bracket 30 further includes two groups of second connecting portions 37. The two splash-proof assemblies 71 are symmetrically arranged on the mounting bracket 30 with the cleaning assembly 13 as the axis of symmetry. Each group of second connecting portions 37 includes two oppositely arranged second connecting portions 37, which are connected with the first support plate 32 and the second support plate 33 respectively. The splash-proof assembly 71 includes a collection disc 711 and a rotating shaft 712. The collection disc 711 has a containing cavity 714, and the top of the containing cavity 714 has a first opening 715. The containing cavity 714 is used for collecting the material splashed from the cleaning channel 132 into the first area. The collection disc 711 is rotatably connected to the corresponding two second connecting portions 37 through the rotating shaft 712. The tensioning sprocket 123 is arranged on one of the two second connecting portions 37 located on the first support plate 32.

[0062] The two splash-proof assemblies 71 symmetrically arranged on both sides can effectively block the splashed material. The splashed material can enter the containing cavity 714 of the collection disc 711 through the first opening 715, which can prevent the material from splashing into the surrounding environment and improve the splash-proof effect.

[0063] The collection disc 711 is rotatably connected to the corresponding group of second connecting portions 37 through the rotating shaft 712. In this way, the collection disc 711 can be slightly rotated or adjusted in angle as needed to better adapt to the direction of material splashing.

[0064] As an implementation form, as shown in Figure 5 The collection disc 711 includes a bottom disc 7111 and a plurality of baffles 7112 surrounding the bottom disc 7111. The splash-proof assembly 71 further includes two telescopic rods 713. The bottom disc 7111 and the plurality of baffles 7112 jointly define the containing cavity 714. The baffle 7112 close to the cleaning assembly 13 is provided with a second opening 716 communicating with the containing cavity 714. The two telescopic rods 713 are vertically arranged. The top of each telescopic rod 713 is connected with the bottom of the corresponding bottom disc 7111. The bottom of each telescopic rod 713 is connected with the top of the bottom plate 311.

[0065] The second opening 716 is arranged to allow the material splashed from the cleaning channel 132 to directly enter the containing cavity 714.

[0066] The height of the telescopic rod 713 is adjusted to allow the collection disc 711 to have a certain inclination angle, so that the material in the containing cavity 714 can naturally slide to the second opening 716 under the action of gravity and enter the lower receiving hopper 20 through the second opening 716. That is, the appropriate inclination angle helps to guide the material to directly fall from the containing cavity 714 of the collection disc 711 into the lower receiving hopper 20 through the second opening 716, and finally enter the collection box 40 through the discharge port 23 of the receiving hopper 20. The whole process is arranged in this way, which not only improves the efficiency of material collection, but also ensures the smooth flow of the material, so as to avoid the material from staying or scattering in the middle of the way, thereby reducing the possibility of material accumulation in the collection disc 711.

[0067] As an embodiment, as shown in Figures 1 to 4 The second driving member 80 is arranged to drive the cleaning assembly 13 to move up and down through the mounting bracket 30, so that one end of the needle column row 51 can extend into or out of the cleaning channel 132.

[0068] It should be understood that the height position of the clamp 50 remains unchanged.

[0069] The second driving member 80 is arranged to accurately control the height of the cleaning assembly 13, so as to ensure that the cleaning channel 132 can accurately approach the needle column row 51 each time of cleaning, and avoid the problems of incomplete cleaning or damage to the clamp 50 due to improper position. On the other hand, the manual operation of the operator is reduced, the risk of accidents is reduced, and the safety of production is improved.

[0070] Before cleaning, the mounting bracket 30 can be at a lower position (original position), and the cleaning channel 132 is away from the needle column row 51 on the clamp 50. When cleaning is needed, the control system sends a command to start the second driving member 80, which can raise the mounting bracket 30 to a suitable position, so that the cleaning channel 132 approaches the needle column row 51 on the clamp 50 to be processed, and the two cleaning brushes 131 in the cleaning assembly 13 rotate relatively to scrape off the material on the needle column row 51. When the cleaning is completed, the control system sends a command again to start the second driving member 80, which can lower the mounting bracket 30 to the original position, so that the cleaning channel 132 is away from the needle column row 51, to wait for the next clamp 50 to be in place, and repeat the above cleaning cycle.

[0071] Optionally, the first driving member 11 can be an electric motor (such as a servo motor), can be a pneumatic motor, or can be a hydraulic motor, and the present disclosure is not limited in this regard.

[0072] Optionally, the second driving member 80 can be an electric actuator, can be a pneumatic cylinder, or can be a hydraulic cylinder, and the present disclosure is not limited in this regard.

Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.

[0074] In addition, it should be noted that each specific technical feature described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0075] In addition, any combination of various different embodiments of the present disclosure can also be made, as long as it does not deviate from the idea of the present disclosure, and it should also be considered as disclosed by the present disclosure.
