Description

Technical Field

[0001] The invention relates to the technical field of foam cotton processing, in particular to an EPE foam cotton thickness detection device. Background Art

[0002] After the EPE foam cotton processing is completed, it is necessary to conduct multiple random inspections on different batches of EPE foam cotton, such as porosity inspection, harmful substance inspection, density inspection, thickness inspection, etc. Among them, thickness inspection is the most common inspection method. In order to ensure the regularity of the inspection, the EPE foam cotton needs to be retained after random inspection.

[0003] When testing the thickness of EPE foam, a thickness gauge is generally used to test a single material, or a CCD camera is used to take photos of the moving EPE foam. When using the thickness gauge, the foam needs to be placed between the measuring head and the measuring table for testing. The testing accuracy is high, but the testing speed is slow. If a CCD camera is used to continuously test the moving EPE foam, a conveyor belt and a conveyor roller are required to drive the EPE foam. When the conveyor roller contacts the EPE foam, the transmission roller will produce an extrusion force on the surface of the EPE foam, causing the surface of the EPE foam to deform. In this case, a longer transmission belt needs to be set until the EPE foam is reset before the EPE foam in a normal state can be tested.

[0004] At the same time, most of the existing testing equipment is used to test EPE foam cotton in a normal state, and the compression coefficient of EPE foam cotton is also an important performance indicator of EPE foam cotton. During the test, it is necessary to squeeze the EPE foam cotton, measure its thickness and calculate it with the thickness of the EPE foam cotton in a normal state to obtain the compression coefficient of the EPE foam cotton. However, the efficiency of measuring the thickness of a single EPE foam cotton after squeezing is too low. When the EPE foam cotton is squeezed and transmitted by a roller, the spacing between the roller and the conveyor belt is too large or too small, which cannot effectively measure the thickness of the EPE foam cotton after squeezing. Therefore, we propose an EPE foam cotton thickness detection device. Summary of the invention

[0020] 1. The EPE foam cotton thickness detection device, because the EPE foam cotton is transmitted under the action of multiple limit teeth, and the multiple limit teeth are installed on the outer peripheral wall of only one end of the transmission roller, one side of the EPE foam cotton will be slightly squeezed downward by the multiple limit teeth, while the other side of the EPE foam cotton will not be squeezed by the limit teeth and will not be deformed.

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The embodiment of the present application provides an EPE foam thickness detection device, which solves the problem that the existing detection equipment is inconvenient to continuously detect the thickness of EPE foam. The first CCD camera 101 can continuously take pictures of the unsqueezed EPE foam and perform continuous thickness detection, and the second CCD camera 102 can continuously take pictures of the fully squeezed EPE foam and perform continuous thickness detection, thereby achieving a more effective continuous detection effect.

[0036] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0037] The embodiment of the invention discloses an EPE foam cotton thickness detection device.

[0038] According to the attached Figure 1-9As shown, it includes a workbench 1, a first CCD camera 101 and a second CCD camera 102 are installed on the front of the workbench 1, and a conveying mechanism is installed above the workbench 1, and the conveying mechanism includes:

[0039] A fixed frame 2 is fixedly installed above the workbench 1, a transmission belt 201 is connected to the inner wall of the fixed frame 2, and a transmission roller 202 is arranged above the transmission belt 201, and a plurality of limiting teeth 203 are installed on the outer peripheral wall of one end of the transmission roller 202, and the transmission roller 202 and the limiting teeth 203 cooperate with the transmission belt 201 to move the EPE foam cotton, and the first CCD camera 101 is arranged on the side of the end of the transmission roller 202 where the limiting teeth 203 are not arranged, the first CCD camera 101 takes pictures of the unextruded EPE foam cotton and performs thickness detection, and the transmission belt 201 and the transmission roller 202 are connected to a first driving component;

[0040] The support frame 3 is fixedly installed above the fixed frame 2. A moving bar 301 is slidably arranged on the inner wall of the support frame 3. A plurality of squeezing rollers 302 are rotatably arranged between the two moving bars 301. A squeezing spring 303 is installed between the moving bar 301 and the inner top wall of the support frame 3. The plurality of squeezing rollers 302 utilize the elastic force of the squeezing spring 303 in cooperation with the transmission belt 201 to adaptively extrude and transmit the EPE foam cotton. The second CCD camera 102 takes pictures of the extruded EPE foam cotton and performs thickness detection, and the plurality of squeezing rollers 302 are connected to a second driving assembly.

[0041] The CCD in the first CCD camera 101 and the second CCD camera 102 is a semiconductor device that can convert an optical image into a digital signal, and further convert the captured image signal into a digital signal, thereby achieving the purpose of thickness detection. This is an existing mature technology and is therefore not described in detail in the embodiments of the invention.

[0042] During use, the first driving component is first used to drive the transmission belt 201 to transmit on the inner wall of the fixed frame 2, and at the same time, the transmission roller 202 above the transmission belt 201 is rotated, and the end of the EPE foam cotton is inserted between the transmission belt 201 and the transmission roller 202, so that the multiple limiting teeth 203 on the outside of the transmission roller 202 are in contact with the EPE foam cotton, and the multiple limiting teeth 203 are slightly inserted above the EPE foam cotton, and then the EPE foam cotton is pushed to continue moving until the EPE foam cotton enters under another transmission roller 202. At this time, the first CCD camera 101 between the two transmission rollers 202 takes a picture of the EPE foam cotton. The transmission is performed under the action of a plurality of limiting teeth 203, and at the same time, the transmission roller 202 has a plurality of limiting teeth 203 installed on only one end of the outer peripheral wall. Then, one side of the EPE foam cotton will be slightly squeezed downward by the plurality of limiting teeth 203 for transmission, while the other side of the EPE foam cotton will not be squeezed by the limiting teeth 203 and will not be deformed. At the same time, the first CCD camera 101 is arranged on the side of the end of the transmission roller 202 where the limiting teeth 203 are not arranged, so that the first CCD camera 101 can continuously take pictures of the un-squeezed EPE foam cotton and perform continuous thickness detection. At the same time, in order to ensure the regularity of the detection, the EPE foam cotton needs to be retained after random inspection, and there is no need to resell it;

[0043] When the end of the EPE foam cotton approaches the multiple squeezing rollers 302, the multiple squeezing rollers 302 are driven to move upward at the same time by the second driving component, and the squeezing spring 303 is compressed, so that the EPE foam cotton enters under the multiple squeezing rollers 302. When the end of the EPE foam cotton moves out from under the squeezing rollers 302, the multiple squeezing rollers 302 are reset, and the multiple squeezing rollers 302 are contacted with the EPE foam cotton under the action of the squeezing spring 303, and the EPE foam cotton is squeezed between the multiple squeezing rollers 302 and the transmission belt 201, so there is no need to operate the multiple squeezing rollers 302 and the transmission belt 201. 01, and the elastic force of the extrusion spring 303 can be used to adaptively extrude the EPE foam, and the number of the extrusion springs 303 and the extrusion rollers 302 can be freely set according to the actual situation, so as to ensure that the multiple extrusion rollers 302 have enough pressure to fully extrude the EPE foam. At the same time, the second driving component drives the multiple extrusion rollers 302 to rotate, and the EPE foam is driven to transmit outward while being squeezed, so that the second CCD camera 102 can continuously take pictures of the EPE foam after being fully squeezed and perform continuous thickness detection, so as to achieve a more effective continuous detection effect.

[0044] Furthermore, the first driving component includes a driving motor 4, which is fixedly installed above the workbench 1. A plurality of rotating shafts 401 are rotatably connected to the inner wall of the fixed frame 2, and a driving end of the driving motor 4 is fixedly connected to one of the rotating shafts 401. A rotating roller 402 is fixedly sleeved on the outer peripheral wall of the rotating shaft 401. The plurality of rotating rollers 402 are tightly abutted against the inner wall of the transmission belt 201. The ends of the plurality of rotating shafts 401 extend outward through the outer wall of the fixed frame 2, and a first chain transmission member 403 is transmission-connected between the ends of two adjacent rotating shafts 401.

[0045] When the driving motor 4 is working, its driving end drives one of the rotating shafts 401 to rotate. Under the action of the multiple first chain transmission members 403, the multiple rotating shafts 401 rotate simultaneously, thereby causing the multiple rotating rollers 402 to rotate and drive the transmission belt 201 to perform circular transmission.

[0046] Furthermore, the first drive assembly also includes a plurality of fixed blocks 404, which are all fixedly mounted on the top of the fixed frame 2, and a first transmission shaft 405 is rotatably connected between the two fixed blocks 404 on the front and back sides, and the transmission roller 202 is fixedly sleeved on the outer peripheral wall of the first transmission shaft 405, and the end of the first transmission shaft 405 is transmission-connected to one of the rotating shafts 401.

[0047] Furthermore, a second transmission shaft 406 is rotatably connected between the back side of the fixed frame 2 and the back side of one of the fixed blocks 404, the second transmission shaft 406 is fixedly sleeved with two mutually meshing transmission gears 407 on the rotating shaft 401 below it, and a second chain transmission member 408 is transmission-connected between the first transmission shaft 405 and the second transmission shaft 406.

[0048] By utilizing the two transmission gears 407, when the rotating shaft 401 rotates, it can drive the second transmission shaft 406 to rotate in the opposite direction, and under the action of the second chain transmission member 408, the first transmission shaft 405 is rotated, and the transmission roller 202 outside the first transmission shaft 405 rotates in the opposite direction relative to the rotating roller 402, so that the rotating roller 402 and the transmission belt 201 can transport the EPE foam cotton therebetween.

[0049] Specifically disclosed, the second driving assembly includes a lifting cylinder 5, the bottom of the lifting cylinder 5 is fixedly connected to a support bar 501, and the end of the support bar 501 is fixedly connected to the top of the support frame 3, and a guide rod 503 is installed above the two movable bars 301. The top ends of the two guide rods 503 extend upward through the top of the support frame 3 and are fixedly connected to a connecting bar 502, and the extrusion spring 303 is movably sleeved on the outer peripheral wall of the guide rod 503.

[0050] It is particularly disclosed that the end of the lifting cylinder 5 extending out of the shaft is connected with an L-shaped bar 504 , and the lower transverse part of the L-shaped bar 504 is in contact with the lower part of the connecting bar 502 .

[0051] When the lifting cylinder 5 is working, it drives the L-shaped bar 504 extending from the end of the shaft to move vertically, and the lower horizontal part of the L-shaped bar 504 is in contact with the lower part of the connecting bar 502. When the L-shaped bar 504 moves upward, it can pull the connecting bar 502 to move upward, and pull the moving bar 301 upward through the guide rod 503, thereby causing the multiple squeezing rollers 302 to move upward and compress the squeezing spring 303. When the lifting cylinder 5 drives the L-shaped bar 504 to reset downward, the L-shaped bar 504 no longer squeezes the connecting bar 502, so that the connecting bar 502 rebounds and resets under the action of the squeezing spring 303, causing the multiple squeezing rollers 302 to move downward and squeeze the EPE foam cotton through the squeezing spring 303.

[0052] It is particularly disclosed that the second driving component also includes a transmission motor 6, which is located on the side of one of the moving bars 301, and a driving shaft 601 is fixedly installed on the driving end of the transmission motor 6. A rotating rod 602 is fixedly inserted on the inner wall of each of the multiple extrusion rollers 302, and the end of the rotating rod 602 extends outward through one of the moving bars 301.

[0053] Furthermore, a third chain transmission member 603 is installed between the end of the driving shaft 601 and one of the rotating rods 602 and between two adjacent rotating rods 602 , and a motor seat 604 is fixedly connected between the bottom of the transmission motor 6 and the lower part of the end of the moving bar 301 .

[0054] By setting up the transmission motor 6, when the transmission motor 6 is working, its driving shaft 601 uses the third chain transmission member 603 to drive the multiple rotating rods 602 to rotate, thereby making the multiple squeezing rollers 302 rotate at the same time, and then the EPE foam cotton squeezed between the multiple squeezing rollers 302 and the transmission belt 201 can be transported.

[0055] The first chain transmission member 403, the second chain transmission member 408 and the third chain transmission member 603 are all composed of two sprockets and a chain. The two sprockets are sleeved on the outside of the corresponding structure, and the chain is driven between the two sprockets, so that the two sprockets can rotate simultaneously.

[0056] Furthermore, the inner walls on both sides of the support frame 3 are provided with limit sliding grooves 605 , and the two ends of the moving bar 301 are fixedly installed with limit sliding blocks 606 , and the limit sliding blocks 606 are in contact with the inner walls of the limit sliding grooves 605 .

[0057] By providing the limiting sliding groove 605 and the limiting sliding block 606 , the moving bar 301 can be limited so that the moving bar 301 can only slide vertically.

[0058] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
