DETAILED DESCRIPTION

[0036] The following is combined with Figure 1 —8 further describes this application in detail.

[0037] The embodiment of the present application discloses a booklet flap forming device.

[0038] The observation view of this device (front, back, left, right) is as follows Figure 1 For reference benchmark.

[0039] Example 1

[0040] Reference Figure 1 A booklet flap forming device includes a machine table 1, a fixing groove 101 is opened on the middle surface of the machine table 1, one side of the bottom of a partition frame 102 is symmetrically fixedly connected to both sides of the machine table 1, a separation groove 103 is arranged between the inner side of the machine table 1 and the inner side of the partition frame 102, and a folding groove 104 is opened inside one side of the partition frame 102.

[0041] By setting, the operator sets the booklet card that needs to be bound in the fixed slot 101, and then puts the pages that need to be bound into the separation slot 103, and the preparation work is completed.

[0042] Reference Figure 1-4 The auxiliary bending mechanism 2 includes a long groove 201 symmetrically opened on both sides of the machine 1, and the circular grooves 202 are opened at the lower end of the inner surface of the long groove 201. The outer wall of the long block 203 is slidably connected to the inside of the long groove 201. The two ends of the spring 204 are respectively fixedly connected to the bottom of the long block 203 and the surface of the long groove 201. The upper end of the limit column 205 is fixedly connected to the lower end of the long block 203. At the same time, the outer wall of the limit column 205 is slidably connected to the inside of the circular groove 202. The inclined surface 206 is arranged on the side of the long block 203 close to the partition frame 102, and the arc surface 207 is arranged at the lower end of the long block 203 close to the inclined surface 206.

[0043] By setting, the operator manually pushes the book inside the fixed groove 101 to move the page inside the separation groove 103 toward the long strip 203. When the page moves toward the long strip 203, the page will first contact the inclined surface 206, and the inclined surface 206 makes the page approach the folding groove 104. When the page continues to slide forward through the inclined surface 206, the page will slowly enter the curved surface 207 (the curved surface 207 needs to be higher than the planes on both sides of the folding groove 104 to prevent creases on the surface of the page). The curved surface 207 will slowly bend the entering page. When the page completely enters the curved surface 207, the auxiliary work is completed.

One side of the extension block 1 315 is fixedly connected to one side of the slider 1 313 and one side of the slider 2 314. The square hole 316 is opened on the surface of one side of the slider 1 313. One side of the extension block 2 317 is fixedly connected to one side of the slider 2 314. The extension block 2 317 is slidably connected to the inside of the square hole 316. The upper ends of the plug-in blocks 318 are fixedly connected to the lower ends of the slider 1 313 and the slider 2 314.

[0045] Among them, the electric push rod 302 is an existing device, which is composed of components such as a screw, a nut, a housing, and a reduction gear. The housing of the electric push rod 302 is fixedly installed on the upper end of the fixed frame 301, and the output end of the electric push rod 302 runs through the interior of the fixed frame 301 and is fixedly connected to the upper surface of the fixed block 303. The input end of the electric push rod 302 is connected to the power socket through an electric wire. The motor 304 is an existing device, which is composed of a stator pole, a rotor (armature), a commutator (commonly known as a commutator), a brush, a casing, a bearing, etc. The housing of the motor 304 is fixedly installed on one side surface of the fixed block 303, the output end of the motor 304 runs through the interior of the fixed block 303 and is fixedly connected to one side of the bevel gear 305, and the input end of the motor 304 is connected to the power socket through an electric wire. Since the electric push rod 302 and the motor 304 are both existing equipment, they are not described in detail here. The follower 307 is composed of two driven wheels and a connecting column.

[0046] By setting, the operator turns on the power to start the electric push rod 302, and the output end of the electric push rod 302 begins to push the fixed block 303 downward. When the fixed block 303 begins to move downward through the output end of the electric push rod 302, the plug-in block 318 begins to contact the page first (the width of the plug-in block 318 is smaller than the width of the folding groove 104), and the page is inserted into the folding groove 104. When the fixed block 303 continues to slide downward, at this time, the bottom of the extension block 315 begins to contact and squeeze the long block 203. When the long block 203 is squeezed, the long block 203 slides downward inside the long groove 201, and the spring 204 is squeezed by the long block 203 and begins to shrink, and the limit column 20 The pages bent in the arc surface 207 slide downward in the circular groove 202 through the extrusion of the long strip block 203. At the same time, the arc surface 207 pushes the extra bent pages inside toward the folding groove 104 through the downward movement of the long strip block 203. The pages pushed out by the arc surface 207 are driven toward the inside of the folding groove 104 through the plug-in block 318, so that the pages on the upper surface of the partition frame 102 on both sides of the folding groove 104 are flat. At this time, the fixed block 303 continues to slide downward. When the bottom of the slider 2 314 and the slider 1 313 move to the surface of the partition frame 102, the output end of the electric push rod 302 no longer pushes downward. At this time, the short pages can be closed.

[0047] When it is necessary to close the edge of a page of longer length, the motor 304 is powered on to drive the motor 304, so that the output end of the motor 304 starts to rotate forward inside the fixed block 303. Through the forward rotation of the output end of the motor 304, the bevel gear 1 305 drives one side of the driven member 307 to rotate inside the fixed cavity 1 306. When the driven member 307 starts to rotate, the other side of the driven member 307 drives the bevel gear 2 309 to rotate inside the fixed cavity 2 308. Through the rotation of the bevel gear 2 309, the bidirectional screw rod 311 starts to rotate inside the movable cavity 310. Through the rotation of the bidirectional screw rod 311, the ball 312 starts to rotate inside the movable cavity 310. The bidirectional screw rod 311 rolls in the groove on the outer wall, and through the rolling of the ball 312, the slider 1 313 and the slider 2 314 begin to slide to both sides inside the active cavity 310. When the slider 1 313 and the slider 2 314 slide to both sides inside the active cavity 310, the extension block 2 317 slides outward inside the square hole 316. At the same time, the bottom of the slider 1 313 and the slider 2 314 form an angle with the top of the plug-in block 318, and begin to close the unclosed part of the page along the surface of the partition frame 102 on one side of the folding groove 104. After the closing is completed, the motor 304 can be powered off.

[0048] When the page opening is completed, the output end of the electric push rod 302 starts to move upward with the fixed block 303, and the motor 304 starts to reverse, so that the extension block 2 317 slides toward the inside of the square hole 316. When the extension block 2 317 completely slides inside the square hole 316, the output end of the electric push rod 302 no longer contracts and the fixed block 303 returns to its initial height, and the opening is completed.

[0049] The implementation principle of the booklet flap forming device of the embodiment of the present application is as follows: the operator places the book card to be flapped in the fixed slot 101, then puts the page to be flapped into the separation slot 103, and pushes the page in the separation slot 103 toward the direction of the long strip block 203, and bends and approaches the page toward the folding slot 104 through the inclined surface 206 and the arc surface 207, and starts the electric push rod 302 to slide the fixed block 303 downward, and the folding slot 104 is opened through the cooperation of the extension block 1 315 and the long strip block 203. The pages on the surface of the partition frame 102 on one side 104 are flat, and the pages are tightened by the cooperation of the slider 1 313, the slider 2 314 and the plug-in block 318. By starting the motor 304, the slider 1 313 and the slider 2 314 slide to both sides inside the active cavity 310. For the pages with longer lengths, after the tightening is completed, the fixed block 303 is restored to its original height through the contraction of the electric push rod 302 and the reversal of the motor 304, and the extension block 2 317 slides inside the square hole 316 to complete the tightening.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
