Description

Technical Field

[0001] The invention relates to the technical field of paraffin processing, and in particular to a temperature-adjustable constant-temperature test box for paraffin processing. Background Art

[0002] Paraffin, also known as crystalline wax, is a polar solvent that is soluble in gasoline but insoluble in water, methanol and other polar solvents. During the processing of paraffin, a special constant temperature test chamber is required to test the stability of paraffin products placed at different temperatures after processing. However, the existing natural ventilation detection is easily affected by external environmental interference.

[0003] The patent with the patent announcement number CN117019240B discloses a temperature-adjustable constant temperature test box for paraffin processing, including a test box body, a positioning seat, a connecting shell, and a filter screen. The top of the test box body is located above the filter screen and is provided with a shielding auxiliary device; a transposition air bleed assembly; and a circulating pulling member. The patent sets a transposition air bleed assembly, and the output end of the driving motor drives the connecting shaft to drive the turntable to rotate forward and reverse 160 degrees. After the output end of the driving motor drives the turntable to rotate forward 160 degrees, the output end of the driving motor reverses and drives the turntable to reset, thereby expanding the range of the nozzle spraying hot air, so that the heat can be evenly distributed inside the test box body, thereby avoiding uneven heat distribution inside the test box body, and further improving the accuracy of the test of the paraffin workpiece. Through the above technical solution, the problem of uneven heat distribution inside the test box body in the prior art is solved.

[0004] However, the device still has some shortcomings: the device can ensure uniform heat distribution inside the test box, but after the paraffin workpiece inspection is completed, the surface of the paraffin workpiece is prone to slight melting due to the high temperature inside the test box, and timely and uniform heat dissipation is required to ensure the secondary hardening and shaping of the paraffin workpiece to avoid the softening of the outer wall of the paraffin workpiece during the heat release process, thereby causing certain defects. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides a temperature-adjustable constant temperature test box for paraffin processing, which solves the problems raised in the above background technology.

[0006] To achieve the above purpose, the present invention is implemented by the following technical scheme: a temperature-adjustable constant temperature test box for paraffin processing, comprising a base, a constant temperature box is arranged on the top of the base, and a storage groove is opened at the bottom of the inner wall of the constant temperature box, an observation window is arranged on the front of the constant temperature box, and heating components are arranged on the left and right sides of the constant temperature box, and a plurality of heating pipes are arranged on the side of the heating component close to the constant temperature box, and the heating pipes are located inside the constant temperature box; An anti-deformation device is provided inside the thermostatic box, an anti-interference device is provided below the anti-deformation device, and an anti-error device is provided on the back of the anti-interference device; The anti-deformation device includes an electric rotating rod, the bottom of which is rotatably installed at the bottom edge of the inner wall of the constant temperature box, the outer wall of the reciprocating spiral groove of the electric rotating rod passes through and is movably installed with a sliding plate, there are two sliding plates, and the two sliding plates are symmetrically distributed inside the constant temperature box, two temperature detectors are symmetrically and fixedly installed at the bottom edge of the sliding plate, a wave guide plate is fixedly installed at the bottom center of the sliding plate, a linkage plate is fixedly installed between the backs of the two sliding plates, an exhaust fan is fixedly installed on the top of the constant temperature box, and a spiral hose is connected and fixedly installed at the bottom of the exhaust fan, an extraction air gun is fixedly installed inside the sliding plate close to the center of the constant temperature box, a round rod is rotatably installed inside the extraction air gun, and two inclined plates are symmetrically and obliquely fixedly installed on the outer wall of the round rod.

[0007] According to the above technical solution, a reciprocating spiral groove is provided on the outer wall at the top end of the electric rotating rod, the sliding plate is slidably installed on the inner wall of the thermostatic box near one side of the heating component, the bottom of the spiral hose movably passes through the top of the thermostatic box, the top of the extraction air gun is connected and fixedly installed at the bottom of the spiral hose, the paraffin workpiece is placed in the storage groove at the bottom of the inner wall of the thermostatic box, the heating component is started, and the heating component blows hot air to the inside of the thermostatic box over a large area through multiple heating tubes, so that the temperature inside the thermostatic box rises rapidly, and the electric rotating rod is started at the same time. When the electric rotating rod rotates along the bottom of the inner wall of the thermostatic box, the reciprocating spiral groove on its outer wall limits the built-in block of the sliding plate. At this time, the electric rotating rod drives the sliding plate to reciprocate along the inner wall of the thermostatic box Slide downward and reset, the sliding plate drives the temperature detector to move synchronously, and the sliding plate at the left end drives the sliding plate at the right end to move synchronously through the linkage plate, the sliding plate will drive the wave guide plate to move synchronously, and the wave guide plate will guide the hot air through its own wave surface; after the inspection of the paraffin workpiece is completed, start the vacuum pump, and at the same time, the sliding plate drives the extraction air gun to move reciprocatingly downward and reset, the extraction air gun pulls the spiral hose to deform, extend and reset synchronously, and the extraction air gun extracts the heat inside the constant temperature box through the suction force transmitted by the vacuum pump. At the same time, when the extraction air gun extracts heat through strong suction, the two relatively inclined inclined plates inside itself generate rotational force through the injected wind force, and at this time the inclined plate will drive the round rod to rotate inside the extraction air gun.

[0008] According to the above technical scheme, the anti-interference device includes a U-shaped plate, a plurality of rotating wheels, a screw rod, a plurality of tough mesh plates and a through rod. The top of the U-shaped plate is fixedly installed on the bottom of the sliding plate, and the plurality of rotating wheels are symmetrically and rotatably installed inside the U-shaped plate. Both ends of the screw rod are fixedly installed on the side of the rotating wheel close to the center of the U-shaped plate. The interiors of the plurality of tough mesh plates are penetrated and threadedly connected to the outer wall of the screw rod. The outer wall of the through rod is penetrated and fixedly installed inside the plurality of tough mesh plates.

[0009] According to the above technical solution, the U-shaped plate is in contact with the inner wall of the constant temperature box on one side close to the heating component, and the outer walls of several of the rotating wheels are in contact with the inner wall of the constant temperature box. The tops of several of the tough mesh plates are slidably installed on the top of the inner wall of the U-shaped plate. The sliding plate reciprocates downward and drives the U-shaped plate to move synchronously when it is reset. The U-shaped plate drives the rotating wheel to move synchronously along the inner wall of the constant temperature box. The rotating wheel begins to rotate along the inside of the U-shaped plate through the friction between the rotating wheel and the inner wall of the constant temperature box. When the rotating wheel drives the lead screw to move downward, it prompts the lead screw to rotate clockwise. Conversely, when the lead screw rotates clockwise and counterclockwise, the lead screw drives the threaded tough mesh plate to move toward the back of the constant temperature box and reset. Multiple tough mesh plates achieve synchronous movement through the limit of the through rod.

[0010] According to the above technical solution, the anti-interference device also includes a U-shaped frame, a hollow plate and several light source assemblies. The top of the U-shaped frame is fixedly installed at the bottom edge of the U-shaped plate, the bottom of the hollow plate is fixedly installed at the bottom of the inner wall of the U-shaped frame, and the tops of several light source assemblies are fixedly installed at the bottom of the U-shaped frame.

[0011] According to the above technical solution, the top of the hollow plate is designed as an arc surface, and the arc surface of the top of the hollow plate is located on the movement trajectory of the bottom of the tough mesh plate. Several light source assemblies are symmetrically distributed at the bottom of the U-shaped frame. At the same time, the U-shaped plate drives the U-shaped frame to move reciprocatingly downward and reset, and the U-shaped frame drives the hollow plate to move synchronously. At this time, during the lateral movement of the tough mesh plate, it will contact and conflict with the arc surface on the top of the hollow plate. The tough mesh plate is bent and deformed due to the resistance force, and then the curved surface is used to guide the bent tough mesh plate to overcome the resistance of the hollow plate. When the tough mesh plate is reset due to its own toughness, it will swing back and forth to generate vibration. At the same time, the U-shaped frame drives the light source assembly to move synchronously, and the illumination light source emitted by the light source assembly simulates natural light outdoors.

[0012] According to the above technical scheme, the anti-error device includes a contact plate, a dark light plate, a mirror panel and a semi-arc ring. The front of the contact plate is fixedly installed on the back of the U-shaped frame, the bottom of the dark light plate is fixedly installed on the bottom edge of the inner wall of the constant temperature box, the mirror panel passes through and is slidably installed inside the dark light plate on the side close to the center of the constant temperature box, and the semi-arc ring is fixedly installed on the outer wall of the mirror panel on the side close to the center of the constant temperature box.

[0013] According to the above technical solution, a spring is arranged between the outer wall of the mirror panel and the inside of the dark light panel, the arc surface of the outer wall of the semi-arc ring is located on the movement trajectory of the bottom of the contact plate, and the U-shaped frame moves reciprocatingly downward and drives the contact plate to move synchronously when it is reset. During the downward movement of the contact plate, it will contact and resist the arc surface of the outer wall of the semi-arc ring. At this time, the semi-arc ring pushes the mirror panel toward the center of the dark light panel under the resistance of the contact plate. When the contact plate passes over the semi-arc ring, the mirror panel is automatically reset by the spring force and drives the semi-arc ring to reset, and this process is repeated.

[0014] According to the above technical scheme, the anti-error device also includes a U-shaped slide plate, a transmission roller, a transmission rod and a plurality of brush plates. The back side of the U-shaped slide plate close to the inner wall of the constant temperature box is fixedly installed on the front edge of the mirror panel, and the transmission roller is rotatably installed on the outer wall of the U-shaped slide plate away from the center of the dark light plate. Both ends of the transmission rod are fixedly installed on the side of the transmission roller close to the center of the dark light plate, and the plurality of brush plates are equidistant and fixedly installed on the outer wall of the transmission rod.

[0015] According to the above technical solution, the outer wall of the transmission roller is in front contact with the outer wall of the dark light board, and the outer wall of the brush plate is in front contact with the outer wall of the dark light board. When the mirror plate moves toward the center of the dark light board, it drives the U-shaped slide plate to move synchronously. The U-shaped slide plate drives the transmission roller to slide and rub along the front of the outer wall of the dark light board. At this time, the transmission roller begins to rotate along the inside of the U-shaped slide plate through friction, and the transmission roller drives the transmission rod to rotate. When the transmission rod rotates, it drives the brush plate to rotate and brush along the front of the outer wall of the dark light board.

[0016] The present invention provides a temperature-adjustable constant temperature test box for paraffin processing, which has the following beneficial effects: (1) The present invention, through the setting of the anti-deformation device, through the coordination of the electric rotating rod, the sliding plate, the temperature detector, the wave guide plate, the linkage plate, the vacuum pump, the spiral hose, the extraction air gun, the round rod and the inclined plate, relies on the reciprocating motion of the wave guide plate to further accelerate the diffusion range of the hot air, that is, to ensure that the temperature inside the constant temperature box is evenly increased in a short period of time, to avoid local uneven temperature difference inside the constant temperature box, thereby reducing the detection accuracy, and at the same time expand the temperature detection range of the temperature detector, so that the staff can make timely adjustments to the temperature difference unequal areas; at the same time, relying on the rotation disturbance of the inclined plate, the heat flow rate inside the extraction air gun and the spiral hose is effectively accelerated, and at the same time, relying on the guidance of the wave guide plate and the detection of the temperature detector, it is further ensured that the heat inside the constant temperature box can be discharged evenly and quickly, avoiding the melting of part of the surface of the paraffin workpiece due to uneven heat extraction inside the constant temperature box, and avoiding certain defects on the outer wall of the paraffin workpiece due to slow secondary cooling and shaping.

[0017] (2) The present invention sets an anti-interference device, and cooperates with a sliding plate, a U-shaped plate, a rotating wheel, a screw rod, a tough mesh plate, a through rod, a U-shaped frame, a hollow plate and a light source assembly. The tough mesh plate is used to guide the heat ejected from the heating tube in a more delicate manner, thereby further improving the uniform diffusion range of the heat on the original basis. At the same time, the tough mesh plate intercepts dust carried in the hot air during the reciprocating motion, thereby preventing dust from adhering to the outer wall of the heated paraffin workpiece, thereby preventing the paraffin workpiece from being polluted and interfering with subsequent maintenance work. At the same time, the vibration force is used to reduce the adhesion strength of dust to the tough mesh plate, and simultaneously prevent the dust from excessively gathering and adhering to the mesh of the tough mesh plate, thereby preventing the mesh from being blocked and interfering with the heat input. The light source assembly is used to better fit the actual scene of the paraffin workpiece when it is used outdoors, simulating the scene of the paraffin workpiece being heated outdoors and receiving natural light, thereby improving the authenticity of the test data.

[0018] (3) The present invention sets an anti-error device, and cooperates with a U-shaped frame, a contact plate, a dark light plate, a mirror plate, a semi-arc ring, a U-shaped slide plate, a transmission roller, a transmission rod and a brush plate to continuously change the reflective mirror surface of the mirror plate exposed to the outside, and absorbs the light source through the dark light plate to simulate the shadow produced when part of the outdoor paraffin workpiece is blocked by an obstruction. At the same time, the light source is refracted at multiple angles with the help of the mirror plate to avoid the phenomenon of excessive temperature in part of the paraffin workpiece, thereby reducing the error of the result when the paraffin workpiece is tested in a close-to-realized scenario, and ensuring that the test result has a good reference significance; and relying on the rotation of the brush plate to cause regular shadows on the light source emitted by the light source assembly, and performing secondary dispersion refraction on the light source refracted by the mirror plate, to ensure that the paraffin workpiece is irradiated by a non-direct light source, and at the same time, the brush plate ensures the cleanliness of the front side of the outer wall of the dark light plate, to avoid the dark light plate being attached by foreign objects and thus accelerating the oxidation speed, and to avoid the dark light plate from reducing the absorption effect of the light source.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] See also Figure 1-Figure 8 One embodiment of the present invention is: a temperature-adjustable constant temperature test box for paraffin processing, comprising a base, a constant temperature box is arranged on the top of the base, a storage slot is opened at the bottom of the inner wall of the constant temperature box, an observation window is arranged on the front of the constant temperature box, heating components are arranged on both sides of the constant temperature box, a heating component is arranged on a side close to the constant temperature box, and the heating pipes are located inside the constant temperature box; An anti-deformation device is provided inside the thermostatic box, an anti-interference device is provided below the anti-deformation device, and an anti-error device is provided on the back of the anti-interference device; The anti-deformation device includes an electric rotating rod, the bottom of which is rotatably installed at the bottom edge of the inner wall of the constant temperature box, the outer wall of the reciprocating spiral groove of the electric rotating rod passes through and is movably installed with a sliding plate, there are two sliding plates, and the two sliding plates are symmetrically distributed inside the constant temperature box, two temperature detectors are symmetrically and fixedly installed at the bottom edge of the sliding plate, a wave guide plate is fixedly installed at the bottom center of the sliding plate, a linkage plate is fixedly installed between the backs of the two sliding plates, an exhaust fan is fixedly installed on the top of the constant temperature box, a spiral hose is connected to and fixedly installed on the bottom of the exhaust fan, an extraction air gun is fixedly installed inside the sliding plate close to the center of the constant temperature box, a round rod is rotatably installed inside the extraction air gun, and two inclined plates are symmetrically and obliquely fixedly installed on the outer wall of the round rod.

[0023] A reciprocating spiral groove is provided on the outer wall of the top of the electric rotating rod, and the sliding plate is slidably installed on the inner wall of the thermostatic box near one side of the heating component. The bottom of the spiral hose is movable and passes through the top of the thermostatic box, and the top of the extraction air gun is connected and fixedly installed at the bottom of the spiral hose. Through the above cooperation, the reciprocating motion of the wave guide plate 44 is relied on to further accelerate the diffusion range of the hot air, that is, to ensure that the temperature inside the thermostatic box 2 is uniformly heated in a short time, to avoid local uneven temperature difference inside the thermostatic box 2, thereby reducing the detection accuracy, and at the same time expand the temperature detection range of the temperature detector 43, so that the staff can adjust the temperature unequal area in time; through the above cooperation, relying on the rotation disturbance of the inclined plate 410, the heat circulation rate inside the extraction air gun 48 and the spiral hose 47 is effectively accelerated, and at the same time, relying on the guidance of the wave guide plate 44 and the detection of the temperature detector 43, it is further ensured that the heat inside the thermostatic box 2 can be discharged evenly and quickly, to avoid the melting of part of the surface of the paraffin workpiece due to uneven heat extraction inside the thermostatic box 2, and to avoid certain defects on the outer wall of the paraffin workpiece due to slow secondary cooling and shaping.

[0024] When in use, the paraffin workpiece is placed in the storage groove at the bottom of the inner wall of the thermostatic box 2, and the heating component 3 is started. The heating component 3 blows hot air to the inside of the thermostatic box 2 in a large range through multiple heating tubes 31, so that the temperature inside the thermostatic box 2 rises rapidly. At the same time, the electric rotating rod 41 is started. When the electric rotating rod 41 rotates along the bottom of the inner wall of the thermostatic box 2, the reciprocating spiral groove on its outer wall restricts the built-in block of the sliding plate 42. At this time, the electric rotating rod 41 drives the sliding plate 42 to slide down and reset along the inner wall of the thermostatic box 2. The sliding plate 42 with The temperature detector 43 moves synchronously, and the sliding plate 42 at the left end drives the sliding plate 42 at the right end to move synchronously through the linkage plate 45. The sliding plate 42 drives the wave guide plate 44 to move synchronously. The wave guide plate 44 guides the hot air through its own wave surface. Through the above cooperation, the reciprocating motion of the wave guide plate 44 further accelerates the diffusion range of the hot air, that is, the temperature inside the constant temperature box 2 is guaranteed to rise uniformly in a short time, avoiding the local uneven temperature difference inside the constant temperature box 2, thereby reducing the detection accuracy, and at the same time expanding the temperature detection range of the temperature detector 43. The detection range is convenient for the staff to make timely adjustments to the areas with unequal temperature differences; after the paraffin workpiece is inspected, the vacuum fan 46 is started, and at the same time, the sliding plate 42 drives the extraction air gun 48 to move reciprocatingly downward and reset, and the extraction air gun 48 pulls the spiral hose 47 to deform, extend and reset synchronously, and the extraction air gun 48 extracts the heat inside the constant temperature box 2 through the suction force conducted by the vacuum fan 46. At the same time, when the extraction air gun 48 extracts the heat through the strong suction force, the two relatively inclined inclined plates 410 inside the vacuum fan 48 generate a rotational force through the injected wind force. The plate 410 will drive the round rod 49 to rotate inside the extraction air gun 48. Through the above cooperation, the rotation disturbance of the inclined plate 410 can effectively accelerate the heat circulation rate inside the extraction air gun 48 and the spiral hose 47. At the same time, relying on the guidance of the wave guide plate 44 and the detection of the temperature detector 43, it is further ensured that the heat inside the constant temperature box 2 can be discharged evenly and quickly, avoiding the melting of part of the surface of the paraffin workpiece due to uneven heat extraction inside the constant temperature box 2, and avoiding certain defects on the outer wall of the paraffin workpiece due to slow secondary cooling and shaping.

[0025] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an anti-interference device 5; The anti-interference device 5 includes a U-shaped plate 51, a plurality of rotating wheels 52, a screw rod 53, a plurality of tough mesh plates 54 and a through rod 55. The top of the U-shaped plate 51 is fixedly installed on the bottom of the sliding plate 42, the plurality of rotating wheels 52 are symmetrically and rotatably installed inside the U-shaped plate 51, both ends of the screw rod 53 are fixedly installed on the side of the rotating wheel 52 close to the center of the U-shaped plate 51, the plurality of tough mesh plates 54 are penetrated inside and threadedly connected to the outer wall of the screw rod 53, and the outer wall of the through rod 55 is penetrated and fixedly installed inside the plurality of tough mesh plates 54.

[0026] The U-shaped plate 51 is in contact with the inner wall of the thermostatic box 2 on one side close to the heating component 3, the outer walls of several rotating wheels 52 are in contact with the inner wall of the thermostatic box 2, and the tops of several tough mesh plates 54 are slidably installed on the top of the inner wall of the U-shaped plate 51. Through the above cooperation, the tough mesh plates 54 are used to more delicately guide the heat sprayed from the heating tube 31, and further improve the uniform diffusion range of heat on the original basis. At the same time, the tough mesh plates 54 intercept dust carried in the hot air during the reciprocating motion to prevent dust from adhering to the outer wall of the heated paraffin workpiece, thereby preventing pollution of the paraffin workpiece and interference with subsequent maintenance work.

[0027] The anti-interference device 5 also includes a U-shaped frame 56, a hollow plate 57 and a plurality of light source assemblies 58. The top of the U-shaped frame 56 is fixedly mounted on the bottom edge of the U-shaped plate 51, the bottom of the hollow plate 57 is fixedly mounted on the bottom of the inner wall of the U-shaped frame 56, and the tops of the plurality of light source assemblies 58 are all fixedly mounted on the bottom of the U-shaped frame 56.

[0028] The top of the hollow plate 57 is designed as an arc surface, and the arc surface of the top of the hollow plate 57 is located on the movement trajectory of the bottom of the tough mesh plate 54. Several light source components 58 are symmetrically distributed at the bottom of the U-shaped frame 56. Through the above cooperation, the vibration force is relied on to reduce the adhesion strength of dust to the tough mesh plate 54, and at the same time, excessive accumulation and adhesion of dust is avoided to cause clogging of the mesh holes of the tough mesh plate 54, thereby interfering with the heat input, and relying on the light source component 58 to better fit the actual scene of the paraffin workpiece when used outdoors, simulating the scene of the paraffin workpiece being heated outdoors and receiving natural light, thereby improving the authenticity of the test data.

[0029] When in use, the sliding plate 42 reciprocates downward and resets, driving the U-shaped plate 51 to move synchronously. The U-shaped plate 51 drives the rotating wheel 52 to move synchronously along the inner wall of the thermostatic box 2, and the rotating wheel 52 begins to rotate along the inside of the U-shaped plate 51 through the friction between the inner wall of the thermostatic box 2 and the rotating wheel 52. When the rotating wheel 52 drives the screw rod 53 to move downward, it causes the screw rod 53 to rotate clockwise. Conversely, when the screw rod 53 rotates clockwise and counterclockwise, the screw rod 53 drives the threadedly connected tough mesh plate 54 to move toward the back direction of the thermostatic box 2 and reset. Multiple tough mesh plates 54 achieve synchronous movement through the limit of the through rod 55. Through the above cooperation, the tough mesh plate 54 is used to guide the heat sprayed from the heating tube 31 in a more delicate manner, and the uniform diffusion range of the heat is further improved on the original basis. At the same time, the tough mesh plate 54 intercepts the dust carried in the hot air during the reciprocating movement to prevent the dust from adhering to the outer wall of the heated paraffin workpiece, thereby preventing the paraffin workpiece from being contaminated and interfering with the later maintenance work; at the same time, the U-shaped The plate 51 drives the U-shaped frame 56 to move reciprocatingly downward and reset, and the U-shaped frame 56 drives the hollow plate 57 to move synchronously. At this time, during the lateral movement of the tough mesh plate 54, it will contact and conflict with the arc surface at the top of the hollow plate 57, and the tough mesh plate 54 will bend and deform due to the resistance force. Then, the arc surface guides the tough mesh plate 54 in a bent posture to overcome the resistance of the hollow plate 57. When the tough mesh plate 54 is reset, it will swing back and forth to generate vibration due to its own toughness. At the same time, the U-shaped frame 56 drives the light source assembly 58 to move synchronously. The light source emitted by the light source assembly 58 simulates outdoor natural light. Through the above cooperation, the vibration force is relied on to reduce the adhesion strength of dust to the tough mesh plate 54, and the dust is simultaneously prevented from excessively gathering and adhering to cause the mesh of the tough mesh plate 54 to be blocked, thereby interfering with the heat input. In addition, the light source assembly 58 is relied on to be more in line with the actual scene of the paraffin workpiece when used outdoors, simulating the scene of the paraffin workpiece being heated outdoors and receiving natural light, thereby improving the authenticity of the test data.

[0030] See also Figure 1-Figure 8 , based on the above embodiment, another embodiment of the present invention further includes an error prevention device 6; The anti-error device 6 includes a contact plate 61, a dark light plate 62, a mirror plate 63 and a semi-arc ring 64. The front of the contact plate 61 is fixedly installed on the back of the U-shaped frame 56, the bottom of the dark light plate 62 is fixedly installed on the bottom edge of the inner wall of the constant temperature box 2, the mirror plate 63 passes through and is slidably installed inside the dark light plate 62 near the center of the constant temperature box 2, and the semi-arc ring 64 is fixedly installed on the outer wall of the mirror plate 63 near the center of the constant temperature box 2.

[0031] A spring is arranged between the outer wall of the mirror plate 63 and the inside of the dark light plate 62. The arc surface of the outer wall of the semi-arc ring 64 is located on the movement trajectory of the bottom of the resistance plate 61. The reflective mirror surface of the mirror plate 63 exposed to the outside is continuously changed through the above cooperation, and the light source is absorbed by the dark light plate 62 to simulate the shadow produced when part of the outdoor paraffin workpiece is blocked by an obstruction. At the same time, the light source is refracted at multiple angles with the help of the mirror plate 63 to avoid the phenomenon of excessive temperature in part of the paraffin workpiece, thereby reducing the error of the result when the paraffin workpiece is tested in a close-to-realized scenario, ensuring that the test result has a good reference significance.

[0032] The anti-error device 6 also includes a U-shaped slide 65, a transmission roller 66, a transmission rod 67 and a plurality of brush plates 68. The back of the U-shaped slide 65 close to the inner wall of the constant temperature box 2 is fixedly installed on the front edge of the mirror panel 63, and the transmission roller 66 is rotatably installed on the outer wall of the U-shaped slide 65 away from the center of the dark light plate 62. Both ends of the transmission rod 67 are fixedly installed on the side of the transmission roller 66 close to the center of the dark light plate 62, and a plurality of brush plates 68 are equidistant and fixedly installed on the outer wall of the transmission rod 67.

[0033] The outer wall of the driving roller 66 is in front contact with the outer wall of the dark light plate 62, and the outer wall of the brush plate 68 is in front contact with the outer wall of the dark light plate 62. Through the above cooperation, the rotation of the brush plate 68 creates regular shadows on the light source emitted by the light source assembly 58, and performs secondary dispersion refraction on the light source refracted by the mirror plate 63, thereby ensuring that the paraffin workpiece is irradiated by a non-direct light source. At the same time, the brush plate 68 ensures the cleanliness of the outer wall of the dark light plate 62, prevents the dark light plate 62 from being attached to foreign objects, thereby accelerating the oxidation speed, and prevents the dark light plate 62 from reducing the absorption effect of the light source.

[0034] When in use, the U-shaped frame 56 moves downward reciprocatingly and drives the contact plate 61 to move synchronously when resetting. During the downward movement of the contact plate 61, it will contact and resist the outer wall arc surface of the semi-arc ring 64. At this time, the semi-arc ring 64 pushes the mirror plate 63 to move toward the inner center direction of the dark light plate 62 under the resistance of the contact plate 61. When the contact plate 61 passes over the semi-arc ring 64, the mirror plate 63 is automatically reset by the spring force and drives the semi-arc ring 64 to reset, and so on. Through the above cooperation, the reflective mirror surface of the mirror plate 63 exposed to the outside is continuously changed, and the light source is absorbed by the dark light plate 62 to simulate the shadow generated when part of the outdoor paraffin workpiece is blocked by an obstruction. At the same time, the light source is refracted at multiple angles with the help of the mirror plate 63 to avoid the phenomenon of excessive temperature in part of the paraffin workpiece, thereby reducing the result error when the paraffin workpiece is detected in a close-to-realized scenario, ensuring the detection result It has good reference significance; when the mirror plate 63 moves toward the center direction of the dark light plate 62, it drives the U-shaped slide plate 65 to move synchronously, and the U-shaped slide plate 65 drives the transmission roller 66 to slide and rub along the outer wall front of the dark light plate 62. At this time, the transmission roller 66 begins to rotate along the inside of the U-shaped slide plate 65 through friction, and the transmission roller 66 drives the transmission rod 67 to rotate. When the transmission rod 67 rotates, it drives the brush plate 68 to rotate and brush along the outer wall front of the dark light plate 62. Through the above cooperation, the rotation of the brush plate 68 causes regular shadows to the light source emitted by the light source assembly 58, and the light source refracted by the mirror plate 63 is secondary dispersed and refracted, ensuring that the paraffin workpiece is irradiated by a non-direct light source. At the same time, the brush plate 68 ensures the cleanliness of the outer wall front of the dark light plate 62, avoids the dark light plate 62 from being attached to foreign objects, thereby accelerating the oxidation speed, and avoiding the dark light plate 62 from reducing the absorption effect of the light source.
