Technical Field
[0001] This utility model relates to the technical field of product film application, specifically a constant pressure rolling application fixture. Background Technology
[0002] The surface of long, narrow iron parts needs to be covered with a protective film or adhesive film for subsequent mounting operations. In existing technology, the film is applied to the surface of the long, narrow iron parts by using a pressure roller. In actual use, the pressure roller will deviate from side to side, and the pressure applied during manual operation will vary significantly. Especially when the length of the long iron part exceeds 20 centimeters, it is almost impossible for manual operation to maintain a stable pressure. This leads to unstable film quality on the surface of long, narrow iron parts, which is prone to defects and increases processing costs. Furthermore, because manual pressure and guidance are required, operators are prone to fatigue, resulting in low film application efficiency. Utility Model Content
[0003] To address the aforementioned problems, this utility model provides a constant pressure rolling fixture, which allows operators to easily apply film to the surface of long strip iron parts, with stable film quality and high processing efficiency.
[0004] A constant pressure rolling fixture, characterized in that it comprises: Base; A pair of guide rails; Iron part positioning mold; Guide seat; A pressure roller module includes a pressure roller mounting frame and a pressing roller. The pressing roller is connected to the lower mounting space of the pressure roller mounting frame via a rotating shaft, and the lower part of the pressing roller protrudes from the lower surface of the pressure roller mounting frame. Pressure sensor; Pressure sensor limit bolt, pressure sensor limit adjusting nut; And the adjusting bolts for the pressure roller module; The upper surface of the base has corresponding guide rails on both sides in the width direction. A metal positioning mold is located in the center of the upper surface of the base in the width direction. The cavity of the metal positioning mold is located at the top and is used to position long metal pieces. The length of the long metal piece is parallel to the length direction of the guide rails. Slider blocks are fixedly mounted on both sides of the bottom of the guide seat. The bottom of the sliders is embedded in the corresponding guide rail arrangement. A pressure roller module mounting cavity is located in the center of the guide seat in the width direction. Straight guide structures are provided at the four top corners of the pressure roller mounting frame, and these straight guide structures penetrate the guide seat. The guide hole arrangement includes two sets of pressure roller module adjusting bolts positioned on either side of the width of the pressure roller mounting frame. Each set of pressure roller module adjusting bolts is threaded onto an adjusting nut, passes through a connecting hole, and is then fixed to the lower part of the pressure roller mounting frame. A pressure sensor is mounted at the center of the upper part of the pressure roller mounting frame. The top sensing end of the pressure sensor is positioned directly below the pressure sensor limiting bolt. By adjusting the pressure sensor limiting adjusting nut, the lower part of the pressure sensor limiting bolt is prevented from contacting the top sensing end of the pressure sensor when not pressed, ensuring that the pressure during the action of the pressing roller is reliably output through the top sensing end.
[0005] Its further features are: It also includes a data display, which is mounted on the side of the base via a bracket. The data display is used to display the pressure data curve in real time when the pressure sensor applies the film along the surface of the long iron piece, so as to ensure accurate control of the pressure value. The top of the guide seat is also fixed with a handle, which makes it easier for the user to apply the film. The gripping part of the handle is cylindrical or elliptical to ensure a comfortable grip for the operator; The positioning mold for iron parts is provided with a positioning column structure in its cavity, which facilitates the reliable positioning of long iron parts. The outer side of the cavity of the iron part positioning module is also provided with a membrane positioning protrusion, which facilitates reliable positioning of the membrane. The iron part positioning mold has a protruding part directly below the cavity position. The base has a concave contour mounting cavity corresponding to the protruding part. The four corners of the iron part positioning mold are respectively aligned and installed on the upper surface of the base through guide posts. The four corners of the iron part positioning mold are also connected to the base through buffer springs. The buffer springs ensure that the pressure is not too great and thus does not deform the long iron part. The cavity is provided with several adsorption holes, which extend to the lower convex part. The side convex part of the conformal mounting cavity is connected to an adsorption air passage. The bypass part of the adsorption air passage is provided with an external protruding interface, which is used to connect an air suction device, so that the long iron piece can be reliably adsorbed in the cavity. The guide seat is provided with auxiliary rollers on both sides of the pressure roller module. The auxiliary rollers are arranged on both sides of the pressure roller module by mounting brackets. The auxiliary rollers are used to balance the forces on both sides of the pressing roller. The auxiliary rollers are only pressed onto the non-cavity upper surface of the iron part positioning mold. Connecting blocks are fixed to both sides of the bottom of the guide seat. The two ends of the connecting blocks protrude outward from the guide seat in the length direction. Slider blocks are fixed to the lower surfaces of the two ends of the connecting blocks in the length direction. The arrangement of the two sets of sliders ensures that the guide seat moves smoothly and reliably. Limit blocks are provided at both ends of the slide rail along its length. The limit blocks are used to ensure that the guide seat does not derail.
[0006] After adopting the solution of this utility model, the long iron piece is placed in the cavity for positioning, and then the film is positioned on the upper surface of the long iron piece. By adjusting the adjusting nut, the pressing roller and the film are adjusted to a suitable height position. Then, by adjusting the pressure sensor limit bolt, the bottom position of the pressure sensor and the pressure sensor limit bolt are matched. Then, only a thrust is needed to drive the guide seat to move along the guide rail, so that the pressing roller presses the film onto the surface of the long iron piece. The pressure transmitted by the pressure sensor is a constant pressure, which allows the operator to easily complete the film application to the surface of the long iron piece, and the film application quality is stable with high processing efficiency.

Detailed Implementation
[0008] A constant pressure rolling fixture, see Figures 1-4 It includes a base 10, a pair of guide rails 20, an iron part positioning mold 30, a guide seat 40, a pressure roller module 50, a pressure sensor 60, a pressure sensor limit bolt 70, an adjusting nut 80, and a pressure roller module adjusting bolt 90. The pressure roller module 50 includes a pressure roller mounting frame 51 and a pressing roller 52. The pressing roller 52 is connected to the lower mounting space of the pressure roller mounting frame 51 through a rotating shaft, and the lower part of the pressing roller 52 protrudes from the lower surface of the pressure roller mounting frame 51. The upper surface of the base 10 has corresponding guide rails 20 on both sides in the width direction. A metal positioning mold 30 is located in the center area of the upper surface of the base 10 in the width direction. The cavity of the metal positioning mold 30 is located at the top and is used to position the long metal piece 100. The length of the long metal piece 100 is parallel to the length direction of the guide rail 20. Slider blocks 41 are fixedly mounted on both sides of the bottom of the guide seat 40. The bottom of the sliders 41 is embedded in the corresponding guide rail 20. A pressure roller module mounting cavity 42 is located in the center of the guide seat 40 in the width direction. Straight guide bolts 43 are respectively provided at the four corners of the top of the pressure roller mounting frame 51, and the straight guide bolts 43 penetrate the corresponding guide rails of the guide seat 40. The hole arrangement includes two sets of pressure roller module adjusting bolts 90 arranged on both sides of the width direction of the pressure roller mounting frame 51. Each set of pressure roller module adjusting bolts 90 is threaded to the adjusting nut 91 and then passes through the connecting hole to be fixed to the lower part of the pressure roller mounting frame 51. A pressure sensor 60 is installed at the upper center of the pressure roller mounting frame 51. The top sensing end 61 of the pressure sensor 60 is located directly below the pressure sensor limiting bolt 70. By adjusting the pressure sensor limiting adjusting nut 80, the lower part of the pressure sensor limiting bolt 70 does not contact the top sensing end 61 of the pressure sensor 60 when it is not pressed, and ensures that the pressure when the pressing roller 52 is in motion is reliably output through the top sensing end 61.
[0009] In specific implementation, it also includes a data display 110, which is mounted on the side of the base 10 via a bracket 120. The data display 110 is used to display the pressure data curve when the pressure sensor 60 applies the film along the surface of the long iron piece 100 in real time, so as to ensure accurate control of the pressure value. A handle 44 is also fixed to the top of the guide seat 40, which makes it easier for users to apply the film. The grip portion of the handle 44 is cylindrical or elliptical to ensure a comfortable grip for the operator; The cavity of the iron part positioning mold 30 is provided with a positioning column structure 31, which facilitates the reliable positioning of the long iron part 100. The outer side of the cavity of the iron part positioning module 30 is also provided with a membrane positioning protrusion 32, which facilitates reliable positioning of the membrane. The iron part positioning mold 30 has a protruding part 33 directly below the cavity position. The base 10 has a concave contour mounting cavity 11 corresponding to the protruding part 33. The four corners of the iron part positioning mold 30 are respectively aligned and installed on the upper surface of the base 10 through guide posts 34. The four corners of the iron part positioning mold 30 are also connected to the base through buffer springs 35. The buffer springs 35 ensure that the pressure is not too large and thus deforms the long iron part 100. The cavity is provided with several adsorption holes, which extend to the lower protrusion 33. The side protrusion of the conformal mounting cavity 11 is connected to the adsorption air passage 12. The bypass part of the adsorption air passage 12 is provided with an external protrusion interface 13. The external protrusion interface 13 is used to connect the air suction device, which makes the long iron piece 100 reliably adsorbed in the cavity. The guide seat 40 is provided with auxiliary rollers 130 on both sides of the pressure roller module 50. The auxiliary rollers 130 are arranged on both sides of the pressure roller module 50 through the mounting bracket 131. The auxiliary rollers 130 are used to balance the forces on both sides of the pressing roller 52. The auxiliary rollers 130 are only pressed onto the non-cavity upper surface of the iron part positioning mold 30. Connecting blocks 45 are fixedly connected to both sides of the bottom of the guide seat 40. The two ends of the connecting blocks 45 protrude outward from the guide seat 40 in the length direction. Slider 41 is fixedly installed on the lower surface of the two ends of the connecting blocks 45 in the length direction. The arrangement of the two sets of sliders 41 ensures that the guide seat 40 moves smoothly and reliably. Limit blocks 140 are provided at both ends of the slide rail 20 along its length. The limit blocks 140 are used to ensure that the guide seat 40 does not derail.
[0010] Its working principle is as follows: A long strip of iron is placed and positioned inside the cavity. Then, the film is positioned on the upper surface of the long strip of iron. By adjusting the adjusting nut, the pressing roller and the film are adjusted to a suitable height position. Then, by adjusting the pressure sensor limit bolt, the bottom position of the pressure sensor and the pressure sensor limit bolt are matched. After that, only a thrust is needed to drive the guide seat to move along the guide rail, so that the pressing roller presses the film onto the surface of the long strip of iron. The pressure transmitted by the pressure sensor is a constant pressure, which allows the operator to easily complete the film application to the surface of the long strip of iron, and the film application quality is stable with high processing efficiency.
