Description

Technical Field

[0001] The present invention belongs to the technical field of thin film detection, and relates to a production detection device for Teflon thin films. Background Art

[0002] Teflon thin film is a fluoropolymer material discovered by DuPont in 1938. Due to its excellent chemical stability and outstanding physical properties, PTFE has been widely used in many industrial fields. PTFE thin film is a product obtained by processing PTFE resin into a thin sheet material through a specific process, and has a low coefficient of friction, excellent chemical corrosion resistance, a wide working temperature range, excellent electrical insulation performance, and unique waterproof and breathable properties. During the production of Teflon thin film, in order to ensure the quality of the final product, it is necessary to detect the thin film.

[0003] Currently, when detecting Teflon thin film, usually a sampling detection method is adopted to detect the Teflon thin film. During detection, a section of the thin film is intercepted during the operation of the production line, and then a predetermined pressure is applied to this section of the thin film for detection. If the thin film can maintain its characteristics under the set pressure and does not break or deform, it means that the products of this batch are qualified products. However, during detection, only a small section is randomly selected from the entire production process for testing, which is difficult to represent the quality status of the entire batch of thin films, easily resulting in a difference between the detection result and the quality of the actual product, and the obtained detection result is not good. Summary of the Invention

[0004] In view of this, the present invention provides a production detection device for Teflon thin films.

[0005] The technical implementation solution of the present invention is: a production detection device for Teflon thin films, including a base, side plates, a control panel, electric pressure wheels, electric wheels, a pressure application mechanism, and a detection mechanism. On both sides of the top of the base, side plates are connected in the middle. A control panel is connected to the top of the base. An electric pressure wheel is rotatably connected between the upper parts of the two side plates. An electric wheel is connected between the lower parts of the two side plates. A plurality of receiving grooves are evenly spaced along the circumferential direction on the electric pressure wheel. A plurality of grooves are evenly spaced along the circumferential direction on the electric wheel. The number of the receiving grooves is the same as the number of the grooves. A pressure application mechanism is provided on the electric pressure wheel, and the pressure application mechanism can apply pressure to the thin film. A detection mechanism is provided on the electric wheel, and the detection mechanism can detect whether there are defects in the thin film after being pressurized.

[0006] As an improvement to the above solution, the pressure applying mechanism includes a sliding frame, extrusion columns, elastic element one, elastic element two, and a guide assembly. The sliding frame is slidably connected in the receiving groove, and elastic element one is connected between the sliding frame and the receiving groove. Multiple extrusion columns are slidably connected at even intervals on the sliding frame, and elastic element two is connected between the extrusion columns and the sliding frame. A guide assembly is provided between the side plate and the sliding frame, and the guide assembly is used to drive the sliding frame to move.

[0007] As an improvement to the above solution, the guide assembly includes a connecting frame, a guide ring, and an extension column. The connecting frame is connected to the upper part of the side of the two side plates that are close to each other. The guide ring is connected to the connecting frame. The guide ring has a notch at the bottom. The part of the guide ring near the right side of the notch is inclined downward. Extension columns are connected to both sides of the sliding frame. The extension columns are located inside the guide ring. The inclined position of the guide ring is located at the movement trajectory of the extension column.

[0008] As an improvement to the above solution, the detection mechanism includes a sliding frame, an elastic element three, and a distance sensor. The sliding frame is slidably connected in the groove of the electric wheel, and the elastic element three is connected between the sliding frame and the bottom of the groove. A distance sensor is installed on the lower front side of the sliding frame. The distance sensor can detect the distance between itself and the middle of the electric wheel. The distance sensor is electrically connected to the control panel.

[0009] As an improvement to the above solution, a marking mechanism is also included. The marking mechanism includes a marking rod, a sliding block, a magnetic attraction component, and an elastic element. Multiple marking grooves are evenly spaced along the circumference of the electric wheel. A sliding block is slidably connected in the marking groove. An elastic element is connected between the sliding block and the marking groove. A marking rod is installed on the top of the sliding block. The marking rod can move upward to contact the film. A magnetic attraction component is provided between the marking groove and the sliding block.

[0010] As an improvement to the above solution, the magnetic attraction component includes an electromagnet and an iron block. An electromagnet is installed at the bottom of the marking groove and is electrically connected to the control panel. An iron block is connected to the bottom of the sliding block, and the electromagnet can attract the iron block when energized.

[0011] As an improvement to the above solution, a guiding mechanism is also included. The guiding mechanism includes connecting rods and support rollers. Connecting rods are connected to both sides of the two side plates, and two support rollers are rotatably connected to the side of the two connecting rods on both sides that are far apart from each other.

[0012] As an improvement to the above solution, it also includes pressing strips. Multiple sets of pressing strips are evenly spaced on both the electric pressing roller and the electric wheel. The number of pressing strip sets is the same as the number of grooves. Each set of pressing strips has two pressing strips. The two pressing strips on the electric wheel are located on both sides of the groove, and the pressing strips on the electric pressing roller are located on both sides of the receiving groove.

[0013] The beneficial effects of the present invention are: 1. When testing Teflon film, the present invention can set up the entire device at the conveying device.

Detailed Implementation

[0027] The above-described solution will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of this application. The implementation conditions used in the embodiments may be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are generally those in routine experiments.

[0028] A Teflon film production testing device, such as Figures 1-5 As shown, the device includes a base 1, side plates 2, a control panel 3, electric pressure rollers 4, electric wheels 5, a pressure application mechanism, and a detection mechanism. Side plates 2 are connected to the middle of the front and rear sides of the top of the base 1. The control panel 3 is connected to the right side of the top of the base 1. Electric pressure rollers 4 are rotatably connected between the upper parts of the two side plates 2, and electric wheels 5 are connected between the lower parts of the two side plates 2. Multiple receiving grooves are evenly spaced along the circumference of the electric pressure rollers 4, and multiple grooves are evenly spaced along the circumference of the electric wheels 5. The number of receiving grooves is the same as the number of grooves. A pressure application mechanism is provided on the electric pressure rollers 4, which can apply pressure to the film 100. A detection mechanism is provided on the electric wheels 5, which can detect whether the film 100 has defects after being pressed.

[0029] like Figures 2-5 As shown, the pressure applying mechanism includes a sliding frame 63, extrusion columns 64, elastic element one 65, elastic element two 67, and a guide assembly. The sliding frame 63 is slidably connected in the receiving groove. Elastic element one 65 is connected between the sliding frame 63 and the receiving groove. Elastic element one 65 is a connecting spring. Multiple extrusion columns 64 are slidably connected at even intervals on the sliding frame 63. Elastic element two 67 is a thrust spring connected between the extrusion column 64 and the sliding frame 63. The extrusion column 64 can apply pressure to the film 100 to detect the film 100. A guide assembly is provided between the side plate 2 and the sliding frame 63. The guide assembly is used to drive the sliding frame 63 to move.

[0030] like Figures 2-5As shown, the guide assembly includes a connecting frame 61, a guide ring 62, and an extension post 66. The connecting frame 61 is connected to the upper part of the two side plates 2 that are close to each other. The guide ring 62 is connected to the connecting frame 61. The guide ring 62 has a notch at the bottom. The part of the guide ring 62 near the right side of the notch is inclined downward. The sliding frame 63 is connected to the extension post 66 on both the front and rear sides. The extension post 66 is located inside the guide ring 62. The inclined position of the guide ring 62 is located at the movement trajectory of the extension post 66, so that the movement of the extension post 66 can contact the inclined position of the guide ring 62.

[0031] like Figures 3-5 As shown, the detection mechanism includes a sliding frame 71, an elastic element 72, and a distance sensor 73. The sliding frame 71 is slidably connected to the groove of the electric wheel 5. An elastic element 72, which is a compression spring, is connected between the sliding frame 71 and the bottom of the groove. A distance sensor 73 is installed on the lower front side of the sliding frame 71. The distance sensor 73 can detect the distance between itself and the middle of the electric wheel 5. The distance sensor 73 is electrically connected to the control panel 3. When the distance sensor 73 detects a change in the distance between itself and the middle of the electric wheel 5, it can send a signal to the control panel 3.

[0032] This device can be used when testing the film 100. During use, the device is placed in the conveying process of the film 100. Initially, the extension column 66 is blocked by the guide ring 62, and the elastic element 65 is compressed. During use, the film 100 in the conveying process passes through the electric pressure roller 4 and electric roller 5. The electric pressure roller 4 and electric roller 5 can then be rotated to convey the film 100. When the electric pressure roller 4 rotates, it drives the sliding frame 63 to rotate, which in turn drives the extension column 66 to rotate. The extension column 66 moves to the notch position of the guide ring 62. At this time, under the action of the elastic element 65, the sliding frame 63 and the extrusion column 64 move downwards. The extrusion column 64 can then compress the film 100, thus testing the compressive strength of the film 100. If the compressive strength of the film 100 is qualified, the film 100 will not rupture, and the extrusion column 64 will not continue to move downwards. When the elastic element 67 is compressed, the electric pressure roller 4 continues to rotate, causing the extension column 66 to contact the inclined part of the guide ring 62 and be squeezed upward by the guide ring 62, thereby causing the sliding frame 63 to move upward. If the compressive strength of the film 100 is not up to standard, the extrusion column 64 will directly pass through the film 100 or cause that part of the film 100 to deform, allowing the extrusion column 64 to continue to move downward. When the extrusion column 64 continues to move downward, it will contact the sliding frame 71 and squeeze the sliding frame 71 downward. The elastic element 72 is compressed, and the downward movement of the sliding frame 71 can drive the distance sensor 73 to move downward. The distance sensor 73 detects the change in distance and sends a signal to the control panel 3, thereby displaying on the control panel 3 that the film 100 has been punctured, thus indicating that the quality of the film 100 is unqualified. In this way, the film 100 can be tested using this device, and during the test, an entire section of the film 100 can be tested during the conveying process, resulting in a more comprehensive test result.

[0033] like Figures 6-8 As shown, it also includes a marking mechanism, which includes a marking rod 91, a sliding block 92, a magnetic attraction component, and an elastic element 95. The electric wheel 5 has multiple marking grooves evenly spaced along its circumference. The sliding block 92 is slidably connected in the marking groove. An elastic element 95, which is a compression spring, is connected between the sliding block 92 and the marking groove. The marking rod 91 is installed on the top of the sliding block 92. The marking rod 91 can move upward to contact the film 100, thereby marking the film 100. A magnetic attraction component is provided between the marking groove and the sliding block 92.

[0034] like Figures 6-8As shown, the magnetic attraction assembly includes an electromagnet 93 and an iron block 94. The electromagnet 93 is installed at the bottom of the marking groove. The electromagnet 93 is electrically connected to the control panel 3 so that the control panel 3 can control the electromagnet 93 to be energized. The bottom of the sliding block 92 is connected to the iron block 94. When the electromagnet 93 is energized, it can attract the iron block 94.

[0035] In the initial state, the electromagnet 93 is energized and attracts the iron block 94, while the elastic element 4 95 is in a compressed state, causing the sliding block 92 and the marking rod 91 to retract into the marking groove. When the distance sensor 73 detects a change in distance and sends a signal to the control panel 3, the control panel 3 can control the uppermost electromagnet 93 to be de-energized. At this time, the electromagnet 93 no longer attracts the iron block 94, and under the action of the elastic element 4 95, it pushes the sliding block 92 upward. The upward movement of the sliding block 92 can drive the marking rod 91 upward. The upward movement of the marking rod 91 can contact the film 100, thereby marking the position on the film 100 where the quality is unqualified, so that the staff can observe which position on the film 100 has a defect, which is convenient for subsequent improvement.

[0036] like Figure 9 As shown, it also includes a guiding mechanism, which includes a connecting rod 101 and a support roller 102. The two side plates 2 are connected to the connecting rod 101 on both the left and right sides. The two connecting rods 101 on the left and right sides are rotatably connected to the side that is far away from each other. The two support rollers 102 are arranged symmetrically up and down. During the detection of the film 100, the film 100 can pass through the two support rollers 102 on both sides. The support rollers 102 assist in supporting and guiding the film 100.

[0037] During the transmission of the film 100, the film 100 can pass through the support rollers 102 on the left and right sides one after the other. Then, when the film 100 is being transported, the support rollers 102 on both sides can assist in the transport of the film 100, thereby guiding the transmission of the film 100.

[0038] like Figure 10 and Figure 11 As shown, it also includes pressing strips 11. Multiple sets of pressing strips 11 are evenly spaced on both the electric pressing roller 4 and the electric roller 5. The number of sets of pressing strips 11 is the same as the number of grooves. Each set of pressing strips 11 has two. The two pressing strips 11 on the electric roller 5 are located on both sides of the groove, and the pressing strips 11 on the electric pressing roller 4 are located on both sides of the receiving groove. The pressing strips 11 on the upper and lower sides cooperate to press the film 100 and fix the film 100 in place.

[0039] Although the invention has been described with reference to exemplary embodiments, it should be understood that the invention is not limited to the disclosed exemplary embodiments.
