Description

Technical Field

[0001] This application relates to the field of material mixing technology, specifically to a coating device and a mixing equipment. Background Technology

[0002] Fire assays, due to their wide applicability, good enrichment effect, good sample representativeness, and high accuracy of analytical results, have always been an important means of gold and silver analysis, as well as an important method for gold arbitration. According to the requirements of national standard methods such as GB / T 7739.1-2019 "Chemical Analysis Methods for Gold Concentrates—Determination of Gold and Silver Contents," the fire assay process consists of six main steps: batching, mixing, melting, ash blowing, gold separation, and weighing. Mixing is required during the fire assay process. Currently available automatic mixing equipment operates as follows: a thin film is placed over an elastic material, and this film-coated elastic material is pressed onto a batch of crucibles, sealing the top of the crucibles. A motor drives the entire mechanism to rotate, achieving the mixing effect of the powdered sample inside the crucibles.

[0003] Because a small amount of sample adheres to the membrane after mixing, subsequent mixing operations can easily contaminate later samples. The current solution is for operators to wipe and clean the membrane after mixing to prevent contamination. However, this manual wiping method is not thorough and cannot completely eliminate the risk of sample residue and cross-contamination, thus affecting the accuracy and reliability of subsequent test results. Utility Model Content

[0004] In view of the technical problems existing in the background art, this application provides a coating device and a mixing device. The coating device can replace the coating material, thereby avoiding sample residue and cross-contamination caused by incomplete manual wiping and cleaning, and improving the accuracy and reliability of subsequent test results.

[0005] In a first aspect, embodiments of this application provide a coating device, comprising:

[0006] frame;

[0007] A pressing assembly includes a pressing portion movably disposed relative to the frame, the pressing portion defining a laminating space between itself and the frame for placing a workpiece to be laminated, the pressing portion being movable toward or away from the frame to adjust the height of the laminating space; and...

[0008] The unwinding assembly includes an unwinding roller and a take-up roller rotatably disposed on the pressing section, the unwinding roller and the take-up roller being spaced apart, and the coating material being able to be drawn out from the unwinding roller and wound into the take-up roller through the coating space.

[0009] Furthermore, the pressing assembly also includes a first drive mechanism, which is connected to the pressing part for driving the pressing part to move in a direction closer to or further away from the frame.

[0010] Furthermore, the feeding roller and the take-up roller are arranged along the length direction of the pressing section, and the unwinding assembly also includes two guide rollers, which are rotatably arranged at both ends of the length direction of the pressing section.

[0011] Furthermore, the unwinding assembly also includes a second drive mechanism, which is connected to the take-up roller drive and is used to drive the take-up roller to rotate.

[0012] Furthermore, the second drive mechanism is movably mounted on the frame, and the second drive mechanism is connected to the take-up roller via a clutch structure.

[0013] Furthermore, the clutch structure includes an active member and a driven member that can be interlocked. The active member is connected to the output shaft of the second drive mechanism, and the driven member is connected to the take-up roller.

[0014] Furthermore, the coating apparatus also includes a detection component, which includes a meter for measuring the winding data of the coating material.

[0015] Furthermore, the detection assembly also includes a measuring roller, which is movably positioned relative to the frame to contact the coating material. A meter is connected to the measuring roller to obtain winding data of the coating material by detecting the number of rotations or rotation angle of the measuring roller.

[0016] Furthermore, the outer circumferential surface of the measuring roller is provided with anti-slip texture.

[0017] Secondly, embodiments of this application also provide a mixing device, including the aforementioned coating device.

[0018] The beneficial effects of this utility model are:

[0019] In this invention, the pressing part presses the coating material firmly onto the part to be coated. The unwinding assembly allows the coating material to be drawn from the unwinding roller, passed through the coating space, and then wound onto the take-up roller. After each coating and mixing operation is completed, the take-up roller rewinds the used coating material while simultaneously releasing new coating material from the unwinding roller. This eliminates the need for manual wiping and cleaning, avoiding the risk of sample residue and cross-contamination caused by incomplete manual cleaning. It ensures that the coating material used in each mixing operation is clean, thereby improving the accuracy and reliability of subsequent testing results.

[0039] Fire assays, due to their wide applicability, good enrichment effect, good sample representativeness, and high accuracy of analytical results, have always been an important means of gold and silver analysis, as well as an important method for gold arbitration. According to the requirements of national standard methods such as GB / T 7739.1-2019 "Chemical Analysis Methods for Gold Concentrates—Determination of Gold and Silver Contents," the fire assay process consists of six main steps: batching, mixing, melting, ash blowing, gold separation, and weighing. Mixing is required during the fire assay process. Currently available automatic mixing equipment operates as follows: a thin film is placed over an elastic material, and this film-coated elastic material is pressed onto a batch of crucibles, sealing the top of the crucibles. A motor drives the entire mechanism to rotate, achieving the mixing effect of the powdered sample inside the crucibles.

[0040] Because a small amount of sample adheres to the membrane after mixing, subsequent mixing operations can easily contaminate later samples. The current solution is for operators to wipe and clean the membrane after mixing to prevent contamination. However, this manual wiping method is not thorough and cannot completely eliminate the risk of sample residue and cross-contamination, thus affecting the accuracy and reliability of subsequent test results.

[0041] like Figure 1 and Figure 2 As shown, in order to solve the above-mentioned technical problems, this application provides a coating apparatus 100, including a frame 1, a pressing assembly 2, and an unwinding assembly 3. The pressing assembly 2 includes a pressing part 21 movably disposed relative to the frame 1, and a coating space 11 for placing the workpiece to be coated is defined between the pressing part 21 and the frame 1. The pressing part 21 can move towards or away from the frame 1 to adjust the height of the coating space 11. The unwinding assembly 3 includes a feed roller 31 and a take-up roller 32 rotatably disposed on the pressing part 21. The feed roller 31 and the take-up roller 32 are spaced apart, and the coating material can be drawn out from the feed roller 31, passed through the coating space 11, and wound onto the take-up roller 32.

[0042] In this invention, the pressing part 21 presses the coating material firmly onto the part to be coated. The unwinding assembly 3 guides the coating material from the unwinding roller 31, through the coating space 11, and then winds it up to the take-up roller 32. After each coating and mixing operation, the take-up roller 32 winds up the used coating material while simultaneously releasing new coating material from the unwinding roller 31. This eliminates the need for manual wiping and cleaning, avoiding sample residue and cross-contamination risks associated with incomplete manual cleaning. It ensures that the coating material used in each mixing operation is clean, thereby improving the accuracy and reliability of subsequent testing results.

[0043] It is understandable that the feeding roller 31 and the receiving roller 32 can be set at multiple positions in the pressing part 21, such as the top surface, bottom surface or side surface of the pressing part 21, as long as the smooth transmission of the coating material can be achieved.

[0044] It should be noted that frame 1 refers to the basic support component of the coating device 100, which is used to support the pressing assembly 2, the unwinding assembly 3, and other related components, providing a structural foundation for the stable operation of the entire device. The specific structural form of frame 1 can be adjusted according to actual needs.

[0045] It can be explained that the pressing part 21 refers to applying pressure to the coating material to press it firmly onto the part to be coated. Its specific structure can be a plate-like structure or a block-like structure, and its size and shape can be adapted and adjusted according to the specifications of the part to be coated to meet different coating requirements.

[0046] It can be explained that the unwinding roller 31 is used to wind up unused coating material, releasing the coating material as the take-up roller 32 rotates during the coating process; the take-up roller 32 is used to wind up used coating material, achieving the recycling of the coating material and the replacement of it with new coating material through its rotation. The diameter, length, and other parameters of the unwinding roller 31 and the take-up roller 32 can be adjusted according to the specifications of the coating material (such as width, thickness, roll diameter, etc.). The rotation setting can be achieved through components such as bearings and bushings, improving the smoothness and stability of the rotation and reducing tension fluctuations of the coating material during unwinding and rewinding.

[0047] It can be explained that the interval setting means that the feeding roller 31 and the receiving roller 32 maintain a certain distance in the pressing part, so that the coating material will not interfere when it moves between the two, thereby improving the stability of the coating material winding.

[0048] It is understandable that the movable setting of the pressing part 21 can be achieved in a variety of ways, such as by using a guide rail slider mechanism or a screw nut mechanism.

[0049] like Figure 2 and Figure 3As shown, in some embodiments, the pressing assembly 2 further includes a first driving mechanism 22, which is connected to the pressing part 21 for driving the pressing part 21 to move in a direction close to or away from the frame 1.

[0050] In this embodiment, the first drive mechanism 22 provides power to move the pressing part 21, realizing automated control of the movement of the pressing part 21 without relying on manual adjustment, thus improving operational efficiency. Specifically, the first drive mechanism 22 can be a cylinder, hydraulic cylinder, electric push rod, or motor with lead screw and nut, etc. For example, in one embodiment, a cylinder is used as the first drive mechanism 22. The piston rod of the cylinder is connected to the pressing part 21. By controlling the air intake and exhaust of the cylinder, the pressing part 21 can be driven to move in the direction of approaching or moving away from the frame 1.

[0051] In some embodiments, the feeding roller 31 and the take-up roller 32 are arranged along the length direction of the pressing part 21, and the unwinding assembly 3 further includes two guide rollers 33, which are rotatably arranged at both ends of the pressing part 21 along the length direction.

[0052] In this embodiment, the guide roller 33 can guide the direction of the coating material, so that after the coating material is drawn out from the feed roller 31, it first passes through the direction and support of the guide roller 33, so that it can pass smoothly through the coating space 11. Then, before entering the take-up roller 32, it is turned and positioned by another guide roller 33, thereby improving the smoothness of the coating material conveying.

[0053] In some embodiments, the unwinding assembly 3 further includes a second driving mechanism 34, which is connected to the take-up roller 32 for driving the take-up roller 32 to rotate.

[0054] In this embodiment, the second drive mechanism 34 drives the take-up roller 32 to rotate, enabling it to stably wind up the used coating material. The second drive mechanism 34 can be a motor, such as a stepper motor or a servo motor, connected directly or indirectly to the take-up roller 32 via its output shaft. This allows for precise control of the take-up roller 32's rotation speed and number of rotations, thereby achieving precise control over the winding length of the coating material. This ensures that the length of each new coating material is consistent, meeting the stability requirements of subsequent coating operations.

[0055] It should be noted that during the mixing process, the pressing part 21 needs to remain in contact with the part to be coated. Therefore, in order to reduce the weight on the pressing part 21, the second drive mechanism 34 needs to be removed from the pressing part 21 to avoid the pressing part 21 being affected by excessive load, thus affecting its flexibility of movement and the stability of pressing.

[0056] In some embodiments, the second drive mechanism 34 is movably disposed on the frame 1, and the second drive mechanism 34 is connected to the take-up roller 32 via a clutch structure 35.

[0057] In this embodiment, by movably mounting the second drive mechanism 34 on the frame 1, it avoids placing additional load on the pressing part 21, ensuring the flexibility of the pressing part 21's movement and the stability of the pressing action. The clutch structure 35 allows for the separation and engagement of power between the second drive mechanism 34 and the take-up roller 32. For example, when the pressing part 21 needs to move to adjust the height of the coating space 11, the clutch structure 35 is in the disengaged state. At this time, the second drive mechanism 34 is disconnected from the take-up roller 32, and the pressing part 21 can move smoothly without being restrained by the second drive mechanism 34. When a coating material winding operation is required, the clutch structure 35 is in the engaged state, and the power of the second drive mechanism 34 can be transmitted to the take-up roller 32, driving it to rotate and complete the winding action. Specifically, the movable setting of the second drive mechanism 34 can include adjusting its distance relative to the frame 1 and its distance relative to the take-up roller 32. Its movement can be achieved in various ways, such as by using a cylinder, hydraulic cylinder, or linear motor to drive the second drive mechanism 34.

[0058] It is understandable that the clutch structure 35 can be implemented in various ways, such as using an electromagnetic clutch, a jaw clutch, or a friction clutch. An electromagnetic clutch uses electromagnetic force to engage and disengage the driving and driven components, offering fast response and convenient control. A jaw clutch transmits power through the interlocking of teeth on the driving and driven components, providing a large torque when engaged and featuring a simple structure. A friction clutch relies on the friction between the contact surfaces to transmit power, offering overload protection to prevent damage to the drive mechanism or the take-up roller 32 due to excessive load.

[0059] like Figure 3 As shown, in some embodiments, the clutch structure 35 includes an active member and a driven member that can be interlocked. The active member is connected to the output shaft of the second drive mechanism 34, and the driven member is connected to the take-up roller 32.

[0060] In this embodiment, power transmission is achieved through the interlocking of the driving and driven components, resulting in a simple structure and high transmission efficiency. The interlocking method of the driving and driven components can be adjusted according to specific transmission requirements. For example, the driving component can be configured with an external spline structure, and correspondingly, the driven component can be configured with an internal spline that matches the external spline. When the clutch structure 35 is engaged, the external spline inserts into the internal spline, thereby achieving stable power transmission. Alternatively, the opposite end faces of the driving and driven components can be provided with interlocking protrusions and grooves. In the engaged state, the protrusions are embedded in the grooves, and torque is transmitted through the interlocking action. This interlocking clutch structure 35 can maintain the stability of power transmission, reduce slippage during transmission, and allow the take-up roller 32 to rotate at a preset speed and number of revolutions, thereby ensuring the accuracy of the film material winding.

[0061] In some embodiments, the coating apparatus 100 further includes a detection component 4, which includes a meter 41 for measuring the winding data of the coating material.

[0062] In this embodiment, the meter 41 monitors the winding data of the coated material in real time, such as winding length, winding speed, or number of winding turns, providing data support for the precise control of the coated material. The meter 41 can be an encoder or a grating ruler. When the coated material moves during the winding process, the encoder can convert the number of rotations of the material into an electrical signal through linkage with the take-up roller 32 or the guide roller 33 and transmit it to the control system, which then calculates the winding length. The grating ruler can obtain the winding length data by detecting the displacement change of the edge of the coated material.

[0063] In some embodiments, the detection assembly 4 further includes a measuring roller 42, which is movably disposed relative to the frame 1 to abut against the coating material. A meter 41 is connected to the measuring roller 42 and is used to obtain the winding data of the coating material by detecting the number of rotations or rotation angle of the measuring roller 42.

[0064] In this embodiment, the measuring roller 42 is always in contact with the coating material, ensuring that it rotates synchronously with the movement of the coating material, thereby improving the accuracy of the winding data detection. After the meter 41 is connected to the measuring roller 42, when the measuring roller 42 rotates, the meter 41 (such as an encoder) can directly collect the number of rotations or rotation angle of the measuring roller 42. Combined with the circumference parameter of the measuring roller 42, the winding length of the coating material can be accurately calculated.

[0065] In one embodiment, by abutting the measuring roller 42 against the guide roller 33, the measuring roller 42 can further improve the stability of the contact between the measuring roller 42 and the coating material by utilizing the support of the guide roller 33 on the coating material. Specifically, the movable setting of the measuring roller 42 can be achieved by elastic components such as cylinders or springs.

[0066] In some embodiments, the outer peripheral surface of the measuring roller 42 is provided with anti-slip texture.

[0067] In this embodiment, the anti-slip texture increases the friction between the measuring roller 42 and the coating material, reducing relative sliding between the coating material and the measuring roller 42 during the winding process and improving measurement accuracy. Specifically, the anti-slip texture can be a fine diamond pattern, annular groove pattern, or grid pattern.

[0068] Secondly, embodiments of this application also provide a mixing device, including the aforementioned coating device 100.

[0069] It is understood that the mixing equipment includes the aforementioned coating device 100, and therefore possesses all the beneficial effects of the aforementioned coating device 100, which will not be elaborated further here.

[0070] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
