Description

Technical Field

[0001] This utility model relates to the field of electrothermal film technology, and in particular to a clamping structure for electrothermal film testing. Background Technology

[0002] Electric heating film is a semi-transparent polyester film that generates heat when electricity is applied. Its core is that a conductive heating material is embedded in an insulating material, and heat energy is generated through electric current. Its main function is to provide an efficient, comfortable and energy-saving heating method for indoor spaces.

[0003] A search revealed that CN218481446U, authorized publication number, discloses a clamping mechanism for testing electrothermal films, including two base plates arranged symmetrically. A groove is provided on the top of the front surface of each base plate. The background art mentions that "during the film-making process of electrothermal films, the most common problems are uneven film structure and uneven dispersion of the conductive medium within the film. Therefore, random sampling of the electrothermal film is necessary. However, existing electrothermal films require manual tightening during testing to ensure flatness, which is not only laborious but also results in unevenness and inaccurate testing results." To better address these problems, promote the development of industry technology, and enhance core competitiveness, this application proposes a new structural design that differs from existing technologies. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a clamping structure for testing electrothermal films.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A clamping structure for testing electrothermal film includes a base plate. Two guide rails are fixedly connected to both sides of the upper surface of the base plate. Two sliding sleeves are slidably connected to the outer sides of two adjacent guide rails. A mounting plate is fixedly connected to one side of each sliding sleeve. A dovetail groove is formed on one side of the mounting plate, and two dovetail blocks are slidably connected within the dovetail groove. Two clamping plates are provided between two opposing mounting plates, and the clamping plates are fixed to the dovetail blocks. A fixing plate is detachably connected to the top of two adjacent guide rails via bolts. Two connecting plates are fixedly connected between the two fixing plates. A wedge-shaped plate is fixedly connected to the bottom of each of the two connecting plates. The two upper clamping plates are located between the two wedge-shaped plates. Two second wedge-shaped plates are fixedly connected to the bottom of the base plate, and the two lower clamping plates are located between the two second wedge-shaped plates. A bidirectional lead screw is rotatably connected to the upper surface of the base plate via bearings, and the bidirectional lead screw passes through two of the sliding sleeves and is threadedly connected to them. A cleaning mechanism for sweeping dust from the surface of the electrothermal film is provided on the outer side of the guide rails.

[0006] As a further embodiment of this utility model, the cleaning mechanism includes two brush rollers, and two sliding sleeves are slidably connected to the outer sides of the two adjacent guide rails. Two rotating shafts are rotatably connected between the two sliding sleeves via bearings, and the two brush rollers are respectively fixedly connected to the outer sides of the two rotating shafts.

[0007] As a further embodiment of this utility model, two gears are keyed to the outer sides of the two rotating shafts, and the two gears mesh with each other. A rack is fixedly connected to the upper surface of the base plate, and the rack meshes with one of the gears.

[0008] As a further improvement of this utility model, a clearance groove is provided on one side of each of the two sliding sleeves, and the bidirectional lead screw passes through the clearance groove.

[0009] As a further improvement of this utility model, each of the two sliding sleeves has a threaded hole on one side, and a locking screw is threaded into the threaded hole.

[0010] As a further embodiment of this utility model, the top end of the bidirectional lead screw is detachably connected to a knob for rotating the bidirectional lead screw by bolts through a fixed plate, and a locking nut is threadedly connected to the outer side of the bidirectional lead screw above the fixed plate.

[0011] As a further embodiment of this utility model, a protective pad is fixedly connected to one side of the clamping plate used to clamp the electric heating film, and the protective pad is the same length as the clamping plate.

[0012] The beneficial effects of this utility model are as follows: 1. In this utility model, by using the clamping plate, wedge plate one, and wedge plate two in cooperation, the electric heating film passes through the two wedge plates one and the clamping plate and enters the two wedge plates two. Then, when the two sliding sleeves one connected to it move in opposite directions along the guide rail by the bidirectional screw, the clamping plate will move. During the movement of the clamping plate, the inclined surfaces of wedge plate one and wedge plate two will cause the two clamping plates to move towards each other, thereby clamping the electric heating film. Then, the movement continues, thereby tightening the electric heating film. This not only saves the user's physical strength, but also allows the electric heating film to maintain good flatness, thereby improving the detection effect of the electric heating film.

[0013] 2. In this utility model, by setting up a cleaning mechanism, after the electric heating film is clamped and tightened, the floating dust on the surface of the electric heating film can be cleaned by the cleaning mechanism, thereby avoiding the influence of dust on the surface of the electric heating film on the detection structure and improving the use effect of the clamping structure.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. The described embodiments are only some embodiments of the present utility model, not all embodiments. Other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are all within the protection scope of the present utility model.

[0017] Reference Figures 1-3 A clamping structure for testing an electrothermal film includes a base plate 1. Two guide rails 4 are fixed to both sides of the upper surface of the base plate 1 by bolts. Two sliding sleeves 10 are slidably connected to the outer sides of two adjacent guide rails 4. A mounting plate 3 is fixed to one side of each sliding sleeve 10 by bolts. A dovetail groove 13 is provided on one side of the mounting plate 3. Two dovetail blocks 14 are slidably connected in the dovetail groove 13. Two clamping plates 11 are provided between the two opposing mounting plates 3, and the clamping plates 11 are fixed to the dovetail blocks 14. The clamping plates 11 can move along the dovetail groove 13 through the dovetail blocks 14, so that the two clamping plates 11 can move towards each other to clamp the electrothermal film. The top of each of the two adjacent guide rails 4 is detachably connected to a fixing plate 5 by bolts. Two connecting plates 6 are fixed between the two fixing plates 5 by bolts. Wedge plates 7 are welded to the bottom of each of the two connecting plates 6. The two clamping plates 11 located above are located between the two wedge plates 7 and are in contact with the inclined surfaces of the two wedge plates 7 respectively. Two wedge plates 12 are fixed to the bottom of the base plate 1 by bolts. The two clamping plates 11 located below are located between the two wedge plates 12 and are in contact with the inclined surfaces of the two wedge plates 12 respectively. The distance between the two wedge plates 17 and the two wedge plates 12 is equal to the thickness of the electric heating film after being clamped by the two clamping plates 11, which can clamp it tightly; The upper surface of the base plate 1 is rotatably connected to a double-acting lead screw 9 via a bearing, and the double-acting lead screw 9 passes through two of the sliding sleeves 10 and is threadedly connected to them. The heating film is passed between the two wedge plates 7 and the two clamping plates 11, and the tail end of the heating film is placed between the two wedge plates 12. Then, the double-acting screw 9 is rotated. The double-acting screw 9 engages with the two sliding sleeves 10 through the thread, causing the two sliding sleeves 10 to move in opposite directions along the guide rail 4. The two sliding sleeves 10 will drive the mounting plate 3 to move. The mounting plate 3 drives the clamping plate 11 to move through the dovetail block 14. During the movement, the clamping plate 11 contacts the inclined surfaces of the wedge plates 7 and 12, causing the two clamping plates 11 to move towards each other in the dovetail groove 13 through the dovetail block 14, thereby clamping the heating film with the two clamping plates 11. After the clamping plates 11 clamp the heating film, the bidirectional screw 9 continues to rotate, causing the two clamping plates 11 to enter the gap between the two wedge plates 7 and the two wedge plates 12. Because the clamping plates 11 clamp the heating film, they will tighten the heating film, making it taut. This not only saves the user's physical strength but also allows the heating film to maintain good flatness, thereby improving the detection effect of the heating film. Furthermore, by converting the linear motion of the wedge plates into the opposing displacement of the clamping plates 11 through the inclined plane, the traditional multi-step operation process is simplified, making the operation more convenient.

[0018] In this utility model, the outer side of the guide rail 4 is provided with a cleaning mechanism 2 for cleaning dust on the surface of the electric heating film. The cleaning mechanism 2 includes two brush rollers 18, and the bristles of the two brush rollers 18 are soft wool, which can clean the floating dust while avoiding damage to the surface of the electric heating film. Two adjacent guide rails 4 are slidably connected to the outer sides of two sliding sleeves 16. Two rotating shafts 19 are rotatably connected between the two sliding sleeves 16 through bearings. Two brush rollers 18 are respectively fixed to the outer sides of the two rotating shafts 19 by bolts. Two gears 17 are keyed to the outer sides of the two rotating shafts 19, and the two gears 17 mesh with each other. When the heating film passes between the two wedge plates 7 and the two clamping plates 11 and the tail end of the heating film is placed between the two wedge plates 12, the heating film will pass between the two brush rollers 18. When the heating film is taut, the sliding sleeve 16 is manually pulled to move up and down along the guide rail 4. The sliding sleeve 16 will drive the rotating shaft 19 to move, and the rotating shaft 19 will drive the brush rollers 18 to move up and down, so that the brush rollers 18 can clean the floating dust on the surface of the heating film, avoid the dust on the surface of the heating film from affecting the detection structure, and improve the use effect of the clamping structure.

[0019] In particular, a rack 15 is fixed to the upper surface of the base plate 1 by bolts, and the rack 15 meshes with one of the gears 17. During the movement of the rotating shaft 19, the gear 17 will be driven to move. One of the gears 17 will rotate through meshing with the rack 15, and the meshing of the two gears 17 will cause the other gear 17 to rotate, thereby causing the two rotating shafts 19 to drive the brush roller 18 to rotate, so that the brush roller 18 can better clean the surface of the electric heating film. Both sliding sleeves 16 have a clearance groove on one side, and the bidirectional lead screw 9 passes through the clearance groove. The clearance groove avoids the bidirectional lead screw 9, so as to prevent the bidirectional lead screw 9 from affecting the movement of the sliding sleeve 16. Each of the two sliding sleeves 16 has a threaded hole on one side, and a locking screw 20 is threaded into the threaded hole. The sliding sleeve 16 can be locked and fixed by the locking screw 20, thereby fixing the brush roller 18. The top end of the bidirectional lead screw 9 passes through the fixing plate 5 and is detachably connected to a knob for rotating the bidirectional lead screw 9 by bolts. The outer side of the bidirectional lead screw 9 is threadedly connected to a locking nut 8 above the fixing plate 5. After the heating film is stretched taut, tighten the locking nut 8 to lock the bidirectional lead screw 9, preventing the bidirectional lead screw 9 from rotating and keeping the heating film taut. A protective pad is attached to one side of the clamping plate 11 used to clamp the heating film, and the protective pad is the same length as the clamping plate 11. The protective pad can prevent the clamping plate 11 from damaging the surface of the heating film.

[0020] Working principle: When in use, the electric heating film is passed through the two wedge plates 7 and the two clamping plates 11, and the tail end of the electric heating film is placed between the two wedge plates 12, with the top resting on one side of the wedge plate 7. Then rotate the double-acting screw 9. The double-acting screw 9 will cause the two sliding sleeves 10 to move in opposite directions along the guide rail 4 through the thread engagement between the two sliding sleeves 10. The two sliding sleeves 10 will drive the mounting plate 3 to move. The mounting plate 3 will drive the clamping plate 11 to move through the dovetail block 14. During the movement, the clamping plate 11 will contact the inclined surfaces of the wedge plate 7 and the wedge plate 12, causing the two clamping plates 11 to move towards each other in the dovetail groove 13 through the dovetail block 14, thereby clamping the electric heating film with the two clamping plates 11. After the clamping plate 11 clamps the heating film, the bidirectional screw 9 continues to rotate, so that the two clamping plates 11 enter the gap between the two wedge plates 7 and the two wedge plates 12. As the clamping plate 11 clamps the heating film and moves downward, the clamping plate 11 will tighten the heating film, making the heating film taut. This not only saves the user's physical strength, but also allows the heating film to maintain good flatness, thereby improving the detection effect of the heating film. Then tighten the locking nut 8 to lock the double-acting screw 9, preventing the double-acting screw 9 from rotating and thus keeping the heating film taut. When the heating film passes between the two wedge plates 7 and the two clamping plates 11 and the tail end of the heating film is placed between the two wedge plates 12, the heating film will pass between the two brush rollers 18. When the heating film is taut, the sliding sleeve 16 is manually pulled to move up and down along the guide rail 4. The sliding sleeve 16 will drive the rotating shaft 19 to move, and the rotating shaft 19 will drive the brush roller 18 to move up and down, so that the brush roller 18 can clean the floating dust on the surface of the heating film and prevent the dust on the surface of the heating film from affecting the detection structure. During the movement of the rotating shaft 19, the gear 17 will be driven to move. One of the gears 17 will rotate by meshing with the rack 15, and the meshing of the two gears 17 will cause the other gear 17 to rotate, thereby causing the two rotating shafts 19 to drive the brush roller 18 to rotate, so that the brush roller 18 can better clean the surface of the electric heating film.

[0021] Furthermore, the terms "installation," "setup," "connection," and "socketing" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical or electrical connections; they can refer to direct connections or indirect connections via an intermediate medium, or internal connections between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.
