[0027] Figure 1 The schematic diagram of the structure of the gluing device for screen stretching in the embodiment of the utility model is shown. Figure 2 Shows Figure 1 Enlarged structural diagram of point A in the middle. Figure 3 Shows Figure 1 Enlarged structural diagram of point B in the middle. Figure 4 Shows Figure 1 The enlarged structure diagram at C in the middle. Figure 1-Figure 4 As shown, the utility model discloses a gluing device for screen stretching.
[0028] The gluing device for screen stretching comprises: a support 1, a frame 2 rotatably connected to the support 1, a glue pressing plate 3 for pressing glue, and a chamber 4 for containing glue. The lower end of the frame 2 presses the screen frame. The upper end of the frame 2 is rotatably connected to the middle position of the support 1. The chamber 4 is opened on the frame 2 along the screen frame. The chamber 4 gradually extends outward from bottom to top. The glue pressing plate 3 is horizontally arranged in the chamber 4 and moves along the chamber 4.
[0029] Before the screen is stretched and glued with the glue coating device, the bracket 1 is located above the screen and the frame 2. After the frame 2 is rotated, the inclination angle of the frame 2 is the same as the inclination angle of the screen frame, and the frame 2 presses the screen downward. The glue pressing plate 3 is lifted upward, and the glue flows into the bottom of the chamber 4. The glue pressing plate 3 is pressed downward, and the glue pressing plate 3 applies the glue to the position where the mesh covers the screen frame. The glue pressing plate 3 seals the bottom of the chamber 4, and the frame 2 and the glue pressing plate 3 are moved upward to complete the glue coating.
[0030] By rotating the frame 2 to the same angle as the screen frame, the chamber 4 and the screen frame are prevented from being misaligned, so that the glue is completely applied to the position where the mesh covers the screen frame, and there will be no deviation in the application position and no missed application. The glue is pressed down by the glue pressing plate 3 to make the glue coating thickness uniform. After the coating is completed, the glue pressing plate 3 seals the bottom of the chamber 4 to prevent glue leakage, and the frame 2 can be easily removed.
[0031] A roller 11 is installed at the bottom of the support 1. The support 1 moves along the net stretching machine.
[0032] The support 1 is located outside the frame of the mesh stretching machine. The support 1 is pushed to complete the movement of the screen-stretching gluing device. By moving the screen-stretching gluing device, the frame 2 can be moved above the screen frame, so that the screen-stretching gluing device can complete the coating of different screen frames of a mesh stretching machine or the coating of screen frames of different mesh stretching machines. The roller 11 has a brake function. After the frame 2 moves to the top of the screen frame, the brake is stepped on to limit the position of the support 1.
[0033] The bracket 1 comprises: a crossbar 12, a foot 13, a connecting rod 14 connected to both ends of the crossbar 12, a limiting block 15 slidably arranged on the foot 13, a toggle member 16 eccentrically swingably connected to the foot 13, and a first elastic device 17 arranged in the foot 13. Among them, the connecting rod 14 is slidably arranged on the foot 13. When the toggle member 16 swings to one side, the toggle member 16 pushes the limiting block 15 to limit the connecting rod 14. When the toggle member 16 swings to the other side, the first elastic device 17 pushes the limiting block 15 away from the connecting rod 14.
[0034] The connecting rod 14 is disposed at both ends of the crossbar 12 in the vertical direction. The toggle member 16 is eccentrically swingably connected to the upper end of the base 13. Exemplarily, the first elastic device 17 is a spring.
[0035] The outer surface of the connecting rod 14 is provided with grooves in the up-down direction. Concavities are formed in parallel in the grooves. Protrusions are arranged in parallel on the limiting block 15.
[0036] When the position of the connecting rod 14 needs to be limited, the toggle member 16 swings to one side, and the swinging position of the toggle member 16 contacts and pushes the limiting block 15 , and the protrusion of the limiting block 15 is embedded in the groove to fix the connecting rod 14 on the base 13 .
[0037] When the position of the connecting rod 14 needs to be adjusted, the toggle member 16 swings to the other side, and the swinging position of the toggle member 16 does not push the limiting block 15. The first elastic device 17 pushes the protrusion of the limiting block 15 away from the groove, and the connecting rod 14 moves up and down along the base 13.
[0038] Before the screen is stretched and coated with glue by the glue coating device, the frame 2 presses down the screen frame. After the screen is stretched and coated with glue by the glue coating device, the frame 2 moves upward away from the screen frame. By adjusting the position of the connecting rod 14 on the foot 13, the height of the frame 2 can be adjusted. By swinging the toggle 16, the height of the frame 2 can be limited.
[0039] The bracket 1 is provided with an adjustment rod 18 . The adjustment rod 18 is rotatably connected to the frame 2 . The adjustment rod 18 is threadedly connected to a rotating block 19 . The rotating block 19 contacts the bracket 1 .
[0040] The upper end of the adjusting rod 18 passes through the middle position of the bracket 1. The lower end of the adjusting rod 18 is rotatably connected to the frame 2. The rotating block 19 is located below the cross bar 12.
[0041] The rotating block 19 is rotated upward, and the upper end of the rotating block 19 contacts the lower surface of the cross bar 12 . The rotating block 19 pushes the adjustment rod 18 downward, and the adjustment rod 18 forms a downward pressure on the frame 2 .
[0042] The adjusting rod 18 is sleeved with a second elastic device 21. The second elastic device 21 pushes the adjusting rod 18 downwards.
[0043] Exemplarily, the second elastic device 21 is a spring. The second elastic device 21 is sleeved on the adjustment rod 18 in the up-down direction. The lower end of the second elastic device 21 abuts against the rotating block 19. The upper end of the second elastic device 21 abuts against the crossbar 12.
[0044] The second elastic device 21 forms a continuous elastic thrust on the frame 2, so that when the frame 2 presses down the screen frame, the frame 2 always contacts the screen frame to avoid leakage of glue.
[0045] The chamber 4 includes a first cavity 41 and a second cavity 42 communicating with the lower end of the first cavity 41 .
[0046] The first cavity 41 gradually extends outward from bottom to top. The second cavity 42 is vertically formed in the up-down direction. When the glue plate 3 is placed in the second cavity 42 , the glue plate 3 seals the second cavity 42 .
[0047] When the glue plate 3 is located in the first cavity 41 , the glue flows downward from the first cavity 41 into the second cavity 42 . When the glue plate 3 is located in the second cavity 42 , the glue flows upward from the second cavity 42 into the first cavity 41 .
[0048] The laminated rubber plate 3 comprises: a plate body 31, a velvet surface 32 attached to the bottom of the plate body 31, and a pressure relief hole 33 penetrating the plate body 31. When the laminated rubber plate 3 is placed in the second cavity 42, the pressure relief hole 33 connects the first cavity 41 and the second cavity 42.
[0049] The pressure relief hole 33 passes through the plate body 31 from top to bottom. The thickness of the velvet surface 32 covering the pressure relief hole 33 is relatively thin. When the glue pressing plate 3 is pressed down, the glue in the second cavity 42 passes through the velvet surface 32 and then flows into the first cavity 41 through the pressure relief hole 33. By discharging the excess glue, the thickness of the glue coating is controlled.
[0050] A groove 34 is formed on the lower surface of the plate body 31 . The velvet surface 32 is placed in the groove 34 . The depth of the groove 34 is less than the thickness of the velvet surface 32 , so that the lower surface of the velvet surface 32 protrudes from the lower surface of the plate body 31 .
[0051] Glue will adhere to the suede surface 32, and the suede surface 32 will contact the mesh and the mesh frame, so that the mesh is fixed on the mesh frame.
[0052] A moving rod 36 is provided on the plate body 31. The lower end of the moving rod 36 is connected to the upper surface of the plate body 31. By holding the moving rod 36, the plate body 31 can be conveniently moved.
[0053] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0054] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
