Description
Technical Field
[0001] The utility model belongs to the technical field of window frame yarn pressing devices, in particular to a portable window frame yarn pressing device. Background Art
[0002] During the production of metal mesh screens, it is necessary to press the periphery of the metal mesh into the groove of the window frame, and then use a rubber strip to press the outside of the mesh in the groove. The existing window frame screen pressing device includes a handle, a front pressing wheel at the front end of the handle, and a rear pressing wheel at the rear end of the handle. The mesh is laid on the window frame, and the front pressing wheel is used to fold the mesh above the window frame slot, and the rubber strip is placed in the fold, and then the rear pressing wheel is used to press the rubber strip and the metal mesh into the groove of the window frame. The existing window frame screen pressing device is generally only used to press screens made of nylon mesh and other mesh. The nylon mesh has low elasticity and poor resilience, so no high pressure is required during the process of pressing the rubber strip. However, for the metal mesh, the above-mentioned window frame screen pressing device has the following defects: First, due to the severe rebound of the metal mesh, the mesh is not easy to bend and deform, the downward pressure is large, and the hand is at a certain angle to the horizontal plane when pressing the rubber strip, it is not easy for the operator to exert force, the downward pressure is small, and long-term use increases the fatigue of the operator; second, due to the small downward pressure, the mesh rebounds, the flatness of the screen mesh surface is poor, resulting in poor light transmittance, affecting lighting; third, the downward pressure is small, the edges of the rubber strip and the mesh are not easy to be clamped, the rubber strip and the mesh can easily fall out of the groove, the screen has poor impact resistance and a short service life. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a portable window frame screen pressing device which has large downward pressure, is easy to operate, reduces operator fatigue, has a flat mesh surface, firmly fixes the rubber strip, and has high impact resistance of the window screen.
[0004] In order to solve the above problems, the technical solution adopted by the portable window frame yarn pressing device of the utility model is: it includes a frame and a creasing wheel located in front of the frame, a first pressing wheel frame is arranged below the frame near the front position, a first pressing wheel is arranged on the first pressing wheel frame, a second pressing wheel frame is arranged on the frame behind the first pressing wheel frame, and a second pressing wheel is arranged on the second pressing wheel frame.
[0005] Its additional technical features are:
[0006] The indentation wheel is in the shape of a truncated cone with a larger outer side and a smaller inner side;
[0007] The first pressing wheel is a pulley with a wheel groove, and a first limiting ring is arranged on the side of the first pressing wheel;
[0008] The periphery of the second pressing wheel is a cylinder, and a second limiting ring is arranged on the side surface of the second pressing wheel.
[0009] Compared with the prior art, the portable window frame pressing device provided by the utility model has the following advantages: first, since it includes a frame body and a creasing wheel located in front of the frame body, a first pressing wheel frame is arranged near the front position below the frame body, a first pressing wheel frame is arranged on the first pressing wheel frame, and a second pressing wheel frame is arranged on the frame body behind the first pressing wheel frame, and a second pressing wheel frame is arranged on the second pressing wheel frame. The wire mesh is first spread on the window frame, and the mesh located at the groove is gently pressed down by aligning the creasing wheel with the groove of the window frame, so that the mesh located at the window frame slot is bent and deviates from the mesh groove, and then the rubber strip is put into the mesh groove of the wire mesh, and the frame body of the portable window frame pressing device is laid flat, and the first pressing wheel and the second pressing wheel are pressed on the rubber strip at the same time, and the frame body is pressed down and pushed forward at the same time, so that the rubber strip and the mesh below the rubber strip are pressed into the groove. When pressing down and pushing forward, the frame body is always in a horizontal state, which is convenient for exerting force, and the rubber strip can be pressed down with the help of the operator's body gravity. , easy to operate, reducing operator fatigue, the mesh surface is flat and the rubber strip is firmly fixed, and the window screen has great impact resistance; secondly, because the indentation wheel is a truncated cone with a large outer side and a small inner side, after the mesh above the window frame slot is pressed into the window frame slot, the bottom of the mesh groove formed in the window frame slot is an inclined surface with a low outer side and a high inner side. When the rubber strip and the mesh are pressed down, the mesh is easier to stretch and the mesh surface is flatter; thirdly, because the first pressing wheel is a pulley with a wheel groove, a groove is provided on the side of the first pressing wheel. A first limiting ring is provided, and the rubber strip is placed in the groove of the mesh. The wheel groove of the first pressure wheel is stuck above the rubber strip. When pressing down, the first limiting ring is pressed on the upper edge of the window frame groove, which prevents the rubber strip from rolling during the pressing process and the mesh from retracting, making the screen mesh smoother; fourthly, since the periphery of the second pressure wheel is a cylinder, a second limiting ring is provided on the side of the second pressure wheel. After the first pressure wheel is initially pressed down, the second pressure wheel further presses the rubber strip and the mesh into the bottom of the window frame groove, which is more convenient to use.

[0017] The structure and use principle of the portable window frame yarn pressing device of the utility model are further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0018] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, a schematic diagram of the structure of a portable window frame yarn pressing device of the utility model is shown, which comprises a frame 1 and a creasing wheel 2 located in front of the frame, a first pressing wheel frame 3 is arranged near the front below the frame 1, a first pressing wheel 4 is arranged on the first pressing wheel frame 3, a second pressing wheel frame 5 is arranged on the frame behind the first pressing wheel frame 3, and a second pressing wheel 6 is arranged on the second pressing wheel frame 5.
[0019] First, lay the metal wire mesh on the window frame, align the creasing wheel 2 with the groove of the window frame to gently press down the mesh at the groove, so that the mesh at the window frame slot is bent, and then put the rubber strip into the crease of the metal wire mesh, and lay the frame 1 of the portable window frame screen pressing device flat, press the first pressing wheel 4 and the second pressing wheel 6 on the rubber strip at the same time, press the frame 1 down and push forward at the same time, the rubber strip and the mesh under the rubber strip are pressed into the groove, and the frame is always in a horizontal state when pressing down and pushing forward, which is convenient for exerting force, and the rubber strip can be pressed down with the help of the operator's body gravity, which is convenient for operation, reduces the operator's fatigue, and the mesh surface is flat and the rubber strip is firmly fixed, and the window screen has great impact resistance.
[0020] like Figure 2 and Figure 3 As shown, the creasing wheel 2 is in the shape of a cone with a larger outer side and a smaller inner side. After the mesh above the window frame slot is pressed into the window frame slot, the bottom of the mesh groove formed in the window frame slot is a slope with a lower outer side and a higher inner side. When the rubber strip and the mesh are pressed down, the mesh is easier to stretch and the mesh surface is smoother.
