Description

Technical Field

[0001] The present invention relates to the technical field of anti-deformation performance detection devices, and particularly to an anti-deformation performance detection device for foam plastics. Background Art

[0002] Foam plastics are a type of polymer material formed by a large number of gas micropores dispersed in solid plastics.

[0003] In the fields of industrial production and scientific research, foam plastics are widely used, from the packaging of precision electronic instruments to the thermal insulation layer of building walls. Therefore, their performance is crucial. Among them, the anti-deformation performance greatly affects the reliability and durability of foam plastics in actual use. However, in order to accurately measure this key performance, staff generally use an anti-deformation performance detection device for foam plastics.

[0004] However, the existing anti-deformation performance detection devices for foam plastics have the following deficiencies:

[0005] During the detection, the foam plastic will come into contact with the detection table and the contact plate and have relative movement. At the same time, after the foam plastic is subjected to an external force, friction, extrusion, and collision will occur between its internal structures, which will cause the foam plastic to generate static electricity. When the anti-deformation performance of the foam plastic is detected, there will be foam plastic particles remaining on the surfaces of the detection table and the contact plate. At this time, a detection device without a cleaning function will not be able to automatically clean them, but requires manual cleaning by staff, which not only increases the work intensity of the staff, but also may result in incomplete cleaning.

[0006] Therefore, we propose an anti-deformation performance detection device for foam plastics to solve the problems raised in the above background art. Summary of the Invention

[0007] The purpose of the present invention is to provide an anti-deformation performance detection device for foam plastics. Through a cleaning mechanism, the foam plastic particles remaining on the surfaces of the detection table and the contact plate in the anti-deformation performance detection device can be automatically cleaned and removed, so that manual cleaning by staff is no longer required, which not only reduces the work intensity of the staff, but also improves the use efficiency of the anti-deformation performance detection device, to solve the problems raised in the above background art.

[0008] To achieve the above purpose, the present invention provides the following technical solution: An anti-deformation performance detection device for foam plastics, including a detection mechanism, and a cleaning mechanism is provided on the detection mechanism, and the cleaning mechanism is used to clean the remaining and static-charged foam plastic particles;

A top plate is additionally installed at a position close to the top inside the box body.

[0014] Preferably, two mounting seats are additionally installed at the bottom of the detection table and the top of the top plate. The four mounting seats are divided into two groups. A screw rod is rotatably connected between the insides of each group of mounting seats. A moving plate is threadedly sleeved between the two screw rods.

[0015] Preferably, a pressure sensor is additionally installed at the middle position of the bottom of the moving plate. A contact plate is additionally installed at the bottom end of the pressure sensor. A connecting plate is additionally installed on the outer surface of the contact plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. By setting up a cleaning mechanism, after the foam plastic detection device finishes detecting the foam plastic, it can automatically clean all the foam plastic particles remaining on its contact plate and the detection table, that is, it does not require manual cleaning by the staff, thereby reducing the work intensity and then improving the use efficiency of the foam plastic detection device. When a large piece of foam plastic is taken out from the inside of the box body, first, by the cooperation of the touch screen module, the control module, the double-hole block, the two electric cylinders and the two connecting blocks, the housing, the perforated housing and the two static eliminators can be moved simultaneously. Subsequently, by the cooperation of the high-voltage power supply and the two static eliminators, the static electricity of the foam plastic particles remaining on the contact plate and the detection table can be eliminated. Then, by the touch screen module, the control module, the air inlet pipe, the processing box, the box cover, the conveying pipe and the housing, all the foam plastic particles in the detection table and the space formed by the top of the perforated housing and the housing can be sucked away.

[0021] 2. Then, by the cooperation of the conveying pipe, the processing box, the box cover, the filter screen plate, the air inlet pipe, the started blower, the air outlet pipe, the three-way pipe, one of the opened electric valves and the exhaust pipe, the foam plastic particles carried in the air flow can be filtered and left in the processing box, and the processed gas can be discharged into the environment. When it is necessary to clean the foam plastic particles blocking the surface of the filter screen plate, by the cooperation of the gas discharged from the three-way pipe, the other opened electric valve, the connecting pipe and the nozzle, the foam plastic particles blocking the surface of the filter screen plate can be cleaned by the quickly ejected gas, thereby ensuring that the filter screen plate can continue the filtering operation.

[0022] 3. The present invention can detect the anti-deformation performance of foam plastics by setting up a detection mechanism. When it is necessary to detect the anti-deformation performance of foam plastics, first place the foam plastics to be detected on the detection table, and then, by using the cooperation of the control module, the touch screen module, the laser range finder sensor, the motor, two first sprockets, the first chain, the second chain, two groups of mounting seats, the top plate, the box body and two detection tables, the two screw rods can be moved in the same direction. Subsequently, by using the cooperation of the screw rods rotating in the same direction and the moving plate, the pressure sensor, the contact plate, the connecting plate and the laser range finder sensor can be moved simultaneously.

[0023] 4. When the bottom of the contact plate comes into contact with the top of the foam plastic particles, directly use the cooperation of the touch screen module and the control module to pause the motor, and at the same time zero the pressure sensor. Subsequently, by using the cooperation of the touch screen module, the control module, the motor and the previous linkage components, the contact plate can be moved again. When the data transmitted by the laser range finder sensor changes, it indicates that the foam plastic begins to deform. At this time, the pressure value at this moment will be displayed on the screen of the touch screen module, that is, the staff can know the anti-deformation performance of the foam plastic.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment 1: Please refer to Figures 1-6 and Figures 9-11As shown in the figure, the present invention provides a technical solution: a device for detecting the anti-deformation performance of foamed plastics, including a detection mechanism 1, on which a cleaning mechanism 2 is provided. The detection mechanism 1 includes a box body 101. The fixed ends of two electric cylinders 214 both movably penetrate the inner wall of the box body 101. A detection table 102 is additionally installed near the bottom inside the box body 101. A double-hole block 213 is installed on the detection table 102. A top plate 110 is additionally installed near the top inside the box body 101. Two mounting seats 103 are additionally installed at the bottom of the detection table 102 and the top of the top plate 110. The four mounting seats 103 are divided into two groups. A screw rod 104 is rotatably connected between the interiors of each group of mounting seats 103. A moving plate 105 is threadedly sleeved between the two screw rods 104. A pressure sensor 106 is additionally installed at the middle position of the bottom of the moving plate 105. A contact plate 107 is additionally installed at the bottom end of the pressure sensor 106. A connecting plate 108 is additionally installed on the outer surface of the contact plate 107. A laser distance measuring sensor 109 is additionally installed on the connecting plate 108. A placement box 111 is additionally installed on the surface of the box body 101. The bottom of the placement box 111 and the bottom of the box body 101 are at the same horizontal plane. A blower 201 and a high-voltage power supply 202 are both installed on the top of the box body 101. A processing box 204 is fixed on the top of the placement box 111. A power supply module 112, a control module 115, and a motor 116 are installed on the bottom inner wall of the placement box 111. A touch screen module 114 and a switch button 113 are additionally installed on the placement box 111. The bottom ends of the two screw rods 104 both movably penetrate the bottom inner wall of the box body 101. A first sprocket 117 is additionally installed at the bottom end of each of the two screw rods 104 and the output end of the motor 116. A second sprocket 118 is additionally installed at the bottom end of one of the screw rods 104. The first chain is used for driving connection between two of the first sprockets 117, and the second chain is used for driving connection between the other first sprocket 117 and the second sprocket 118. Threading holes 119 are preset on the inner wall of the box body 101 and the inner wall of the placement box 111, and the interiors of the two threading holes 119 are communicated with each other.

[0039] In this embodiment, when it is necessary to detect the anti-deformation performance of the foam plastic, first open the door of the box body 101, then place the foam plastic to be detected (the height is measured with a tool in advance) on the detection table 102 and make fine movements until the centers of the top of the foam plastic and the bottom of the contact plate 107 are on the same vertical line. Then close the door of the box body 101. After that, press the switch button 113 to electrically connect the control module 115 to the external power supply. Then, with the cooperation of the touch screen module 114, the control module 115 and the laser distance sensor 109, measure the distance between the bottom of the laser end of the laser distance sensor 109 and the top of the detection table 102. After that, the touch screen module 114 will, with the cooperation of the control module 115, subtract the height value of the foam plastic and the distance value between the bottom of the laser end of the laser distance sensor 109 and the bottom of the contact plate 107 (the height is measured with a tool in advance) from the measured distance, and directly transmit the calculated distance value to the touch screen module 114. When the touch screen module 114 receives the transmitted distance data, the touch screen module 114 will directly display the received distance data on its screen. Then, the staff inputs the distance value that the contact plate 107 needs to move on the touch screen module 114, and then presses the start button. At this time, the touch screen module 114 will, with the cooperation of the control module 115, start the motor 116. Then, the started motor 116 will drive the connected first sprocket 117 to rotate. The rotating first sprocket 117 will, with the cooperation of the first chain, the second chain, two sets of mounting seats 103, the top plate 110, the box body 101 and two detection tables 102, make the two screw rods 104 rotate in the same direction. Then, the two screw rods 104 rotating in the same direction will drive the moving plate 105 to move together. After that, the moving moving plate 105 will drive the pressure sensor 106, the contact plate 107, the connecting plate 108 and the laser distance sensor 109 to move simultaneously. When the contact plate 107 moves down to the distance value previously input on the touch screen module 114, the touch screen module 114 will, with the cooperation of the control module 115, pause the motor 116. At this time, the bottom of the contact plate 107 just touches the top of the foam plastic. Then, zero the pressure sensor 106, and then record the distance value at this time (the distance between the bottom of the laser end of the laser distance sensor 109 and the top of the detection table 102). Then, use the touch screen module 114 and the control module 115 to start the motor 116 again, so that the started motor 116 drives the contact plate 107 to move through the previous linkage components again. When the contact plate 107 starts to move, the values transmitted by the laser distance sensor 109 and the pressure sensor 106 will be displayed on the screen of the touch screen module 114 through the control module 115 and automatically recorded. When the data transmitted by the laser distance sensor 109 changes, it means that the foam plastic starts to deform. At this time, the touch screen module 114 will record the pressure value at this time, and then continue the detection.Until the foam plastic breaks, when the detected foam plastic is squeezed and broken, the touch screen module 114 will record the maximum pressure value that the foam plastic can withstand at this time, and then the staff can copy it down.

[0040] Embodiment 2: As Figures 1-12 shown, a cleaning mechanism 2 is provided on the detection mechanism 1. The detection mechanism 1 includes a box body 101. A detection table 102 is additionally installed near the bottom inside the box body 101. Two mounting seats 103 are additionally installed at the bottom of the detection table 102 and the top of the top plate 110. The four mounting seats 103 are divided into two groups. A screw rod 104 is rotatably connected between the interiors of each group of mounting seats 103. A moving plate 105 is threadedly sleeved between the two screw rods 104. A pressure sensor 106 is additionally installed at the middle position of the bottom of the moving plate 105. A contact plate 107 is additionally installed at the bottom end of the pressure sensor 106. A placement box 111 is additionally installed on the surface of the box body 101. A power supply module 112, a control module 115 and a motor 116 are installed at the bottom of the inner wall of the placement box 111. A touch screen module 114 and a switch button 113 are additionally installed on the placement box 111. A cleaning mechanism 2 is provided on the detection mechanism 1. The cleaning mechanism 2 is used to clean the residual and static-charged foam plastic particles. The cleaning mechanism 2 includes a blower 201, a high-voltage power supply 202, a processing box 204, two electric valves 210, a double-hole block 213 and two electric cylinders 214. A filter screen plate 205 for filtering air is provided inside the processing box 204. A box cover 206 is additionally installed on the top of the processing box 204. A spray head 207 for blowing air to the filter screen plate 205 is fixedly penetrated through the top of the box cover 206. The output ends of the two electric valves 210 are respectively installed with a connecting pipe 211 and an exhaust pipe 212. Connecting blocks 215 are installed at the telescopic ends of the two electric cylinders 214. A housing 216 is fixed between the two connecting blocks 215. Installation grooves 217 are preset at the top and bottom of the housing 216. Static eliminator rods 218 are installed inside the two installation grooves 217. The air inlet end of the blower 201 is communicated with an air inlet pipe 203. The air outlet end of the air inlet pipe 203 is connected with the air inlet end of the processing box 204. The top of the filter screen plate 205 is in contact with the bottom of the box cover 206. The air outlet end of the blower 201 is communicated with an air outlet pipe 208. The air outlet end of the air outlet pipe 208 is communicated with a three-way pipe 209. The two electric valves 210 are respectively connected with the two air outlet ends of the three-way pipe 209. The air outlet end of the connecting pipe 211 is connected with the air inlet end of the spray head 207. The two electric cylinders 214 are respectively installed inside the two through holes on the double-hole block 213. A perforated shell 219 is fixed at the position near the top of the outer wall of the housing 216. The air outlet end of the housing 216 is communicated with a conveying pipe 220. The air outlet end of the conveying pipe 220 is connected with the air inlet end of the processing box 204.

[0041] In this embodiment, when a large piece of foam plastic is taken out from the inside of the box body 101, first, the touch screen module 114 and the control module 115 are used in cooperation to start two electric cylinders 214 simultaneously. Then, the two simultaneously started electric cylinders 214 will drive the housing 216 and the two static eliminators 218 and the perforated housing 219 mounted on the housing 216 under the cooperation of the double-hole block 213 and the two connecting blocks 215. When the perforated housing 219 moves to between the contact plate 107 and the detection table 102, the touch screen module 114 will pause the two electric cylinders 214 simultaneously through the cooperation of the control module 115. Then, the high-voltage power supply 202 is turned on, and the output voltage and current parameters of the high-voltage power supply 202 are set according to the specifications of the static eliminators 218. Then, the start button is pressed. At this time, the high-voltage power supply 202 will convert the low voltage transmitted from the external power supply into a stable high voltage, and then respectively send it to the two static eliminators 218. When the high voltage is applied to the discharge needles or electrodes of the two static eliminators 218 respectively, a corona discharge phenomenon will occur at this time. At this time, the air in the corona discharge area will be ionized, and a large number of positive and negative ions will be generated. These ions will attract and neutralize the static charges on the surface of the foam plastic particles, thereby achieving static elimination. Subsequently, the foam plastic particles with static eliminated will not be adsorbed to the detection table 102 and the contact plate 107 they contact. Then, the foam plastic particles in contact with the contact plate 107 will all fall into the space formed by the top of the housing 216 and the perforated housing 219. When the two static eliminators 218 have been used for a period of time, the high-voltage power supply 202 is turned off. Then, the touch screen module 114 and the control module 115 are used in cooperation to start the fan 201 and one of the electric valves 210 (connected to the exhaust pipe 212). At this time, the started fan 201 will obtain suction at each opening of the housing 216 under the cooperation of the intake pipe 203, the processing box 204, the box cover 206, and the conveying pipe 220. Then, the housing 216 with suction will suck the residual foam plastic particles on the detection table 102 and the foam plastic particles inside the above space into its interior. Then, the foam plastic particles entering the interior of the housing 216 will be conveyed into the interior of the conveying pipe 220 along with the rapidly flowing air flow, and then conveyed into the interior of the processing box 204. When the air flow carrying the foam plastic particles enters the interior of the processing box 204, at this time, under the action of the filter screen plate 205, the foam plastic particles carried in the air flow can be filtered out. Then, the air flow from which the foam plastic particles are removed will enter the interior of the intake pipe 203, and then enter the interior of the outlet pipe 208 through the started fan 201, and then enter the interior of the three-way pipe 209. Then, through the cooperation of the opened electric valve 210 and the exhaust pipe 212, it is discharged into the environment. When it is necessary to clean the foam plastic particles blocked on the surface of the filter screen plate 205, at this time, the previous electric valve 210 is closed, and the other electric valve 210 is opened.Subsequently, the airflow output from the tee 209 will be delivered to the interior of the nozzle 207 through the cooperation of the opened electric valve 210 and the connecting pipe 211, and then sprayed out from the outlet of the nozzle 207 onto the surface of the filter mesh plate 205. That is, the blocked foam plastic particles can be cleaned up by the rapidly flowing gas. When the filter mesh plate 205 has been cleaned for a period of time, then close the opened electric valve 210 and open one of the electric valves 210.

[0042] The effect and working principle achieved by the entire mechanism are as follows:

[0043] In the preparation stage, first move the entire anti-deformation performance detection device to the place where it is needed. Subsequently, connect the power supply module 112 to the external power supply through a new wire. Then connect the power supply module 112 to the switch button 113 through a new wire. After that, connect the switch button 113 to the control module 115 through a new wire. Next, connect the control module 115 to the touch screen module 114 through a new wire. Then, connect the pressure sensor 106, the laser distance sensor 109, the motor 116, the blower 201, the two electric valves 210, and the two electric cylinders 214 to the control module 115 through new wires. Finally, connect the high-voltage power supply 202 to the external power supply through a new wire, and at the same time connect the high-voltage power supply 202 to the two static eliminators 218 through new wires;

[0044] During the detection stage, when it is necessary to detect the anti-deformation performance of the foam plastic, first open the door of the box body 101 at this time. Then place the foam plastic to be detected (whose height has been measured with tools in advance) on the detection table 102 and make fine adjustments until the centers of the top of the foam plastic and the bottom of the contact plate 107 are on the same vertical line. Then close the door of the box body 101. After that, press the switch button 113 to electrically connect the control module 115 to the external power supply. Next, using the cooperation of the touch screen module 114, the control module 115, and the laser distance sensor 109, measure the distance between the bottom of the laser end of the laser distance sensor 109 and the top of the detection table 102. After that, the touch screen module 114 will, with the cooperation of the control module 115, subtract the height value of the foam plastic and the distance value between the bottom of the laser end of the laser distance sensor 109 and the bottom of the contact plate 107 (whose height has been measured with tools in advance) from the measured distance, and directly transmit the calculated distance value to the touch screen module 114. When the touch screen module 114 receives the transmitted distance data, at this time, the touch screen module 114 will directly display the received distance data on its screen. Then the staff inputs the distance value that the contact plate 107 needs to move on the touch screen module 114. Then press the start button. At this time, the touch screen module 114 will, with the cooperation of the control module 115, start the motor 116. After that, the started motor 116 will drive the connected first sprocket 117 to rotate. The rotating first sprocket 117 will, with the cooperation of the first chain, the second chain, the two sets of mounting seats 103, the top plate 110, the box body 101, and the two detection tables 102, make the two screw rods 104 rotate in the same direction. Then the two screw rods 104 rotating in the same direction will drive the moving plate 105 to move together. After that, the moving moving plate 105 will drive the pressure sensor 106, the contact plate 107, the connecting plate 108, and the laser distance sensor 109 to move simultaneously. When the contact plate 107 moves down to the distance value previously input on the touch screen module 114, at this time, the touch screen module 114 will, with the cooperation of the control module 115, pause the motor 116. At this time, the bottom of the contact plate 107 just touches the top of the foam plastic. Then zero the pressure sensor 106. Then record the distance value at this time (the distance between the bottom of the laser end of the laser distance sensor 109 and the top of the detection table 102). Then, using the touch screen module 114 and the control module 115 again, start the motor 116 again, so that the started motor 116 drives the contact plate 107 to move through the previous linkage components again. When the contact plate 107 starts to move, at this time, the screen on the touch screen module 114 will display the values transmitted by the laser distance sensor 109 and the pressure sensor 106 through the control module 115 and automatically record them. When the data transmitted by the laser distance sensor 109 changes, it indicates that the foam plastic starts to deform at this time. At this time, the touch screen module 114 will record the pressure value at this time. Then continue the detection until the foam plastic breaks.When the detected foam plastic is crushed by extrusion, the touch screen module 114 will record the maximum pressure value that the foam plastic can withstand at this time, and then the staff can copy it down;

[0045] Cleaning stage: When the foam plastic finishes the detection, at this time, with the cooperation of the touch screen module 114, the control module 115, the motor 116 and the previous linkage components, the contact plate 107 is reset to its original position. Then the motor 116 is paused. Next, the door of the box body 101 is opened, and then the large pieces of foam plastic are taken out from the inside of the box body 101. Then, with the cooperation of the touch screen module 114 and the control module 115, two electric cylinders 214 are started simultaneously. After that, the two simultaneously started electric cylinders 214 will drive the housing 216 and the two static eliminators 218 and the perforated housing 219 installed on the housing 216 to move under the cooperation of the double-hole block 213 and the two connecting blocks 215. When the perforated housing 219 moves between the contact plate 107 and the detection table 102, at this time, the touch screen module 114 will, through the cooperation of the control module 115, pause the two electric cylinders 214 simultaneously. Then the high-voltage power supply 202 is turned on, and the output voltage and current parameters of the high-voltage power supply 202 are set according to the specifications of the static eliminators 218. Then the start button is pressed. At this time, the high-voltage power supply 202 will convert the low voltage transmitted from the external power supply into a stable high voltage, and then respectively transmit it to the two static eliminators 218. When the high voltage is respectively applied to the discharge needles or electrodes of the two static eliminators 218, a corona discharge phenomenon will occur at this time. At this time, the air in the corona discharge area will be ionized and a large number of positive and negative ions will be generated. These ions will attract and neutralize the static charges on the surface of the foam plastic particles, thereby achieving the elimination of static electricity. Subsequently, the foam plastic particles with static electricity eliminated will not be adsorbed to the detection table 102 and the contact plate 107 they contact. Then the foam plastic particles in contact with the contact plate 107 will all fall into the space formed by the top of the housing 216 and the perforated housing 219. When the two static eliminators 218 have been used for a period of time, at this time, the high-voltage power supply 202 is turned off. Then, with the cooperation of the touch screen module 114 and the control module 115, the blower 201 and one of the electric valves 210 (connected to the exhaust pipe 212) are started. At this time, the started blower 201 will, under the cooperation of the intake pipe 203, the processing box 204, the box cover 206 and the conveying pipe 220, make each opening of the housing 216 obtain suction. Subsequently, the housing 216 that obtains suction will suck the residual foam plastic particles on the detection table 102 and the foam plastic particles in the above space into its interior. Then the foam plastic particles that enter the interior of the housing 216 will be transported into the interior of the conveying pipe 220 along with the rapidly flowing air current, and then transported into the interior of the processing box 204. When the air current carrying the foam plastic particles enters the interior of the processing box 204, at this time, under the action of the filter screen plate 205, the foam plastic particles carried in the air current can be filtered out. Subsequently, the air current from which the foam plastic particles are removed will enter the interior of the intake pipe 203, then enter the interior of the outlet pipe 208 through the started blower 201, then enter the interior of the tee pipe 209, and then be discharged into the environment through the opened electric valve 210 and the exhaust pipe 212 in cooperation.When it is necessary to clean the foam plastic particles blocked on the surface of the filter screen plate 205, the previous electric valve 210 is closed at this time, and another electric valve 210 is opened. Subsequently, the air flow output from the tee 209 will be transported to the inside of the spray head 207 through the cooperation of the opened electric valve 210 and the connecting pipe 211, and then sprayed out from the outlet of the spray head 207 and sprayed on the surface of the filter screen plate 205. That is, the blocked foam plastic particles can be cleaned up by using the fast-flowing gas. When the filter screen plate 205 has been cleaned for a period of time, the opened electric valve 210 is closed at this time, and one of the electric valves 210 is opened. When the foam plastic particles on the contact plate 107 and the detection table 102 are cleaned up, the touch screen module 114 and the control module 115 are used to cooperate to pause the fan 201 at this time, and then the two electric cylinders 214 are used to cooperate to reset the housing 216 to its original position.

[0046] Among them, the conveying pipe 220 is movably sleeved inside one of the circular holes preset on the box body 101, and the two new wires (the wires connecting the high-voltage power supply 202 and the two static eliminators 218 respectively) are respectively sleeved inside the other two circular holes preset on the box body 101.

[0047] Among them, the pressure sensor 106, the laser distance sensor 109, the power supply module 112, the switch button 113, the touch screen module 114, the control module 115, the motor 116, the fan 201, the high-voltage power supply 202, the electric valve 210, the electric cylinder 214 and the static eliminator 218 are all prior arts, and their models can be selected according to the actual situation and will not be explained in detail here.
