Description

Technical Field

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

[0002] Teflon 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 film is a product obtained by processing PTFE resin into a sheet-like 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 film, in order to ensure the quality of the final product, it is necessary to detect the film.

[0003] Currently, when detecting Teflon film, usually a sampling detection method is adopted to detect the Teflon film. During the detection, a section of the film is intercepted during the operation of the production line, and then a predetermined pressure is applied to this section of the film for detection. If the film can maintain its characteristics under the set pressure and does not crack or deform, it means that the products of this batch are qualified products. However, during the 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 films, and it is easy to cause a difference between the detection result and the quality of the actual product, resulting in a poor detection result. Summary of the Invention

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

[0005] The technical implementation solution of the present invention is: a production detection device for Teflon film, including a base, side plates, a control panel, an electric pressing wheel, an electric wheel, a pressing 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 pressing 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 pressing 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 pressing mechanism is provided on the electric pressing wheel, and the pressing mechanism can apply pressure to the film. A detection mechanism is provided on the electric wheel, and the detection mechanism can detect whether there are defects in the film after being pressed.

[0006] As an improvement to the above solution, the pressing mechanism includes a sliding frame, a pressing column, a first elastic member, a second elastic member, and a guiding assembly. A sliding frame is slidably connected in the receiving groove. A first elastic member is connected between the sliding frame and the receiving groove.

A notch is provided at the lower part of the guiding ring, and the part of the lower part of the guiding ring close to the right side of the notch slopes downward. Extending columns are connected to both sides of the sliding frame, and the extending columns are located inside the guiding ring. The inclined position of the guiding ring is located at the movement track of the extending columns.

[0008] As an improvement to the above solution, the detection mechanism includes a sliding frame, a third elastic member, and a distance sensor. A sliding frame is slidably connected in the groove of the electric wheel. A third elastic member is connected between the sliding frame and the bottom of the groove. A distance sensor is installed at the lower part of the front side of the sliding frame. The distance sensor can detect the distance between it 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 further included. The marking mechanism includes a marking rod, a sliding block, a magnetic attraction assembly, and a fourth elastic member.

A fourth elastic member is connected between the sliding block and the marking groove. A marking rod is installed at the top of the sliding block. The upward movement of the marking rod can contact the film. A magnetic attraction assembly is provided between the marking groove and the sliding block.

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

[0011] As an improvement to the above solution, a guiding mechanism is further included. The guiding mechanism includes a connecting rod and a supporting roller.

Detailed implementation manners

[0027] The above solution will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are for illustrating the present application and not for limiting the scope of the present application. The implementation conditions adopted in the embodiments can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0028] A Teflon film production and detection device, as Figures 1 - 5 shown, includes a base 1, side plates 2, a control panel 3, an electric pressing wheel 4, an electric wheel 5, a pressing mechanism and a detection mechanism. The middle of the front and rear sides of the top of the base 1 are both connected with side plates 2. The right side of the top of the base 1 is connected with a control panel 3. An electric pressing wheel 4 is rotatably connected between the upper parts of the two side plates 2. An electric wheel 5 is connected between the lower parts of the two side plates 2. A plurality of receiving grooves are evenly spaced along the circumferential direction on the electric pressing wheel 4. A plurality of grooves are evenly spaced along the circumferential direction on the electric wheel 5. The number of the receiving grooves is the same as the number of the grooves. A pressing mechanism is provided on the electric pressing wheel 4. The pressing mechanism can apply pressure to the film 100. A detection mechanism is provided on the electric wheel 5. The detection mechanism can detect whether there are defects in the film 100 after being pressed.

[0029] As Figures 2 - 5 shown, the pressing mechanism includes a sliding frame 63, extrusion columns 64, a first elastic member 65, a second elastic member 67 and a guiding component. A sliding frame 63 is slidably connected in the receiving groove. A first elastic member 65 is connected between the sliding frame 63 and the receiving groove. The first elastic member 65 is a connecting spring. A plurality of extrusion columns 64 are slidably connected to the sliding frame 63 at equal intervals. A second elastic member 67 is connected between the extrusion column 64 and the sliding frame 63. The second elastic member 67 is a thrust spring. The extrusion column 64 can apply pressure to the film 100 to detect the film 100. A guiding component is provided between the side frame and the sliding frame 63. The guiding component is used to drive the sliding frame 63 to move.

[0030] As Figures 2 - 5As shown in the figure, the guiding component includes a connecting frame 61, a guiding ring 62 and an extension column 66. A connecting frame 61 is connected to the upper part of the inner sides of the two side plates 2 close to each other. A guiding ring 62 is connected to the connecting frame 61. A notch is provided at the lower part of the guiding ring 62, and the part of the lower part of the guiding ring 62 close to the right side of the notch is inclined downward. Extension columns 66 are connected to both the front and rear sides of the sliding frame 63. The extension columns 66 are located inside the guiding ring 62, and the inclined position of the guiding ring 62 is located on the movement track of the extension columns 66, so that the movement of the extension columns 66 can contact the inclined position of the guiding ring 62.

[0031] As Figures 3 - 5 shown in the figure, the detection mechanism includes a sliding frame 71, an elastic member III 72 and a distance sensor 73. A sliding frame 71 is slidably connected to the groove of the electric wheel 5. An elastic member III 72 is connected between the sliding frame 71 and the inner bottom of the groove. The elastic member III 72 is a compression spring. A distance sensor 73 is installed at the lower part of the front side of the sliding frame 71. The distance sensor 73 can detect the distance between it and the middle part 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 it and the middle part of the electric wheel 5, it can send a signal to the control panel 3.

[0032] When it is necessary to detect the film 100, this device can be used. During use, this device is set up in the conveying process of the film 100. In the initial state, the extension column 66 is blocked by the guiding ring 62, and the first elastic member 65 is in a compressed state. During use, the film 100 in the conveying process is passed through the electric pressing wheel 4 and the electric wheel 5. Subsequently, the electric pressing wheel 4 and the electric wheel 5 can be controlled to rotate, so as to convey the film 100. When the electric pressing wheel 4 rotates, it will drive the sliding frame 63 to rotate. When the sliding frame 63 rotates, it will drive the extension column 66 to rotate. When the extension column 66 rotates, it will move to the notch position of the guiding ring 62. At this time, under the action of the first elastic member 65, the sliding frame 63 and the extrusion column 64 will move downward. At this time, the extrusion column 64 can extrude the film 100, so as to detect the compressive capacity of the film 100. If the compressive capacity of the film 100 is qualified, the film 100 will not break, and the extrusion column 64 will not continue to move downward. The second elastic member 67 is compressed. Subsequently, when the electric pressing wheel 4 continues to rotate, it will drive the extension column 66 to contact the inclined part of the guiding ring 62 and be extruded upward by the guiding ring 62, so as to drive the sliding frame 63 to move upward. If the compressive capacity of the film 100 is unqualified, the extrusion column 64 will directly pass through the film 100 or cause deformation of this part of the film 100, so that the extrusion column 64 can continue to move downward. When the extrusion column 64 continues to move downward, it will contact the sliding frame 71 and extrude the sliding frame 71 to move downward. The third elastic member 72 is compressed. When the sliding frame 71 moves downward, it can drive the distance sensor 73 to move downward. The distance sensor 73 detects that the distance has changed and sends a signal to the control panel 3, so as to display on the control panel 3 that the film 100 is punctured, thus prompting that the quality of the film 100 is unqualified. In this way, this device can be used to detect the film 100, and during the detection, a whole section of the film 100 can be detected during the conveying process, and the detection result is more comprehensive.

[0033] As Figures 6 - 8 shown, it further includes a marking mechanism. The marking mechanism includes a marking rod 91, a sliding block 92, a magnetic attraction assembly and a fourth elastic member 95. A plurality of marking grooves are evenly spaced along the circumferential direction on the electric wheel 5. The sliding block 92 is slidably connected in the marking groove. An fourth elastic member 95 is connected between the sliding block 92 and the marking groove. The fourth elastic member 95 is a compression spring. The marking rod 91 is installed on the top of the sliding block 92. The upward movement of the marking rod 91 can contact the film 100, so as to mark on the film 100. A magnetic attraction assembly is arranged between the marking groove and the sliding block 92.

[0034] As 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 with an iron block 94, and the energized electromagnet 93 can attract the iron block 94.

[0035] In the initial state, the electromagnet 93 is energized to attract the iron block 94, and the fourth elastic member 95 is in a compressed state, so that the sliding block 92 and the marking rod 91 are retracted 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. Under the action of the fourth elastic member 95, the sliding block 92 is pushed upward. When the sliding block 92 moves upward, it can drive the marking rod 91 to move upward. When the marking rod 91 moves upward, it can contact the film 100, so as to make a mark at the position where the film 100 is unqualified, so that the staff can observe which position on the film 100 has defects and facilitate subsequent improvement.

[0036] As Figure 9 shown, it further includes a guiding mechanism. The guiding mechanism includes a connecting rod 101 and a supporting roller 102. The connecting rod 101 is connected to the left and right sides of the two side plates 2. The two supporting rollers 102 are rotatably connected to the mutually remote sides of the two connecting rods 101 on the left and right sides. The two supporting rollers 102 are symmetrically arranged up and down. During the detection of the film 100, the film 100 can pass through the two supporting rollers 102 on both sides, and the supporting 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 supporting rollers 102 on the left and right sides in sequence. Then when the film 100 is conveyed, the supporting rollers 102 on both sides can assist in conveying the film 100, so as to realize the guiding function for the transmission of the film 100.

[0038] As Figure 10 and Figure 11 shown, it further includes a pressing strip 11. A plurality of groups of pressing strips 11 are evenly spaced on both the electric pressing wheel 4 and the electric wheel 5. The number of groups of pressing strips 11 is the same as the number of grooves. Each group of pressing strips 11 has two. The two pressing strips 11 on the electric wheel 5 are located on both sides of the groove, and the pressing strips 11 on the electric pressing wheel 4 are located on both sides of the receiving groove. The upper and lower pressing strips 11 cooperate to press the film 100 and fix the film 100.
