[0055] Figure 1 The front view of a strapping device 100 according to an embodiment of the present utility model is shown. Figure 2 The rear view of a strapping device 100 according to an embodiment of the present utility model is shown. The following will be described in detail in conjunction with Figure 1 and Figure 2 for a detailed description.

[0056] As Figure 1 and Figure 2 shown, the strapping device 100 includes a support plate 110, a driving mechanism 120, and two hemming mechanisms 130. The support plate 110 is arranged in a horizontal posture. The two hemming mechanisms 130 are arranged at intervals along a first direction on the upper side of the support plate 110. Among them, one hemming mechanism 130 is used to fold one end of the waist seal paper, and the other hemming mechanism 130 is used to fold the other end of the waist seal paper. By successively folding the two ends of the waist seal paper through the two hemming mechanisms 130, the two ends of the waist seal paper can be overlapped in a cross manner. Figure 3 The schematic diagram of a partial structure of the hemming mechanism 130 according to an embodiment of the present utility model is shown. As Figures 1 to 3 shown, the hemming mechanism 130 includes a vacuum suction gripper 131, a rotating wheel 132, and a first rotating driver 133. Among them, the surface of the vacuum suction gripper 131 ( Figure 3The upper surface is provided with a number of adsorption holes 1311. By connecting the vacuum suction claw 131 to a vacuum pumping device, the vacuum suction claw 131 can firmly hold the waistband paper by using the suction force generated by the vacuum pumping device. The rotating wheel 132 is provided with a wheel axle, and the vacuum suction claw 131 is connected to the rotating wheel 132 and is offset from the wheel axle of the rotating wheel 132. Optionally, the vacuum suction claw 131 is connected to the edge of the rotating wheel 132. The output shaft of the first rotation driver 133 is interconnected with the wheel axle of the rotating wheel 132. The first rotation driver 133 can be a motor, a rotary electromagnet, etc., and it can drive the rotating wheel 132 to rotate around its wheel axle (e.g., clockwise rotation, counterclockwise rotation), thereby enabling the vacuum suction claw 131 to switch between a first position and a second position. Figure 4 FIG. Figure 4 shows a schematic diagram of the vacuum suction claw 131 in the first position according to an embodiment of the present invention. Figure 5 FIG. Figure 5 shows a schematic diagram of the vacuum suction claw 131 in the second position according to an embodiment of the present invention, as Figure 4 and Figure 5 shown. The first position is lower than the second position. When the vacuum suction claw 131 is in the first position, the surface of the vacuum suction claw 131 provided with the adsorption holes 1311 faces upward, and the vacuum suction claw 131 can easily adsorb and fix the waistband paper from the lower side of the waistband paper. When the vacuum suction claw 131 switches from the first position to the second position, the surface of the vacuum suction claw 131 provided with the adsorption holes 1311 faces downward, and during this process, the vacuum suction claw 131 can fold the end of the waistband paper by a preset angle, so that the end of the waistband paper is folded above the book.

[0057] As Figure 1 shown, the driving mechanism 120 is arranged below the support plate 110. The driving mechanism 120 is configured to drive the support plate 110 to lift and lower along the second direction, and the driving mechanism 120 is further configured to drive the two hemming mechanisms 130 to approach or move away from each other along the first direction. When using the bundling device 100 for bundling operations, the two hemming mechanisms 130 can first fold the two ends of the waistband paper so that the two ends of the waistband paper cross and overlap above the book (as Figure 4 shown). Then, the driving mechanism 120 drives the support plate 110 to descend (i.e., drives the two hemming mechanisms 130 to descend), and at the same time drives the two hemming mechanisms 130 to approach each other, so that the two ends of the waistband can be accurately aligned and bonded together (one end of the waistband is pre-coated with an adhesive), thereby realizing the fast and accurate bundling of the waistband.

[0058] According to an embodiment of the present invention, as Figure 3 shown, the vacuum suction claw 131 can include a first pipe section 1312 and a second pipe section 1313 that are connected and communicate with each other. Among them, the first pipe section 1312 is connected to the rotating wheel 132, and the second pipe section 1313 is connected to one end of the first pipe section 1312 (Figure 3 the end far from the rotating wheel 132), and a preset included angle is formed between the first pipe section 1312 and the second pipe section 1313. For example, in Figure 3 the illustrated embodiment, the first pipe section 1312 and the second pipe section 1313 are perpendicular to each other. The adsorption hole 1311 is arranged on the surface of the end of the second pipe section 1313 far from the first pipe section 1312. Optionally, the first pipe section 1312 and the second pipe section 1313 are integrally formed.

[0059] According to an embodiment of the present invention, as Figures 1 to 3 shown, the hemming mechanism 130 may further include a carrier plate 134 and a connecting seat 135. Wherein, the carrier plate 134 is arranged on the support plate 110 and configured to slide along a first direction. Optionally, a guide rail is arranged along the first direction on the upper side of the support plate 110, and a slider is connected to the lower side of the carrier plate 134, and the slider is slidably connected to the guide rail. The carrier plate 134 is used to provide support and installation positions for other components in the hemming mechanism 130. For example Figures 1 to 3 shown, the connecting seat 135 and the first rotary driver 133 are both installed on the upper side of the carrier plate 134, and the wheel shaft of the rotating wheel 132 is pivotally connected to the connecting seat 135.

[0060] According to an embodiment of the present invention, as Figure 1 and Figure 3 shown, the first rotary driver 133 and the rotating wheel 132 can be driven through a belt transmission module 136. Specifically, a first belt pulley is connected to the output shaft of the first rotary driver 133, a second belt pulley is connected to the wheel shaft of the rotating wheel 132, and the first belt pulley and the second belt pulley are connected by a belt to achieve transmission. Optionally, the belt is a synchronous belt, and the first belt pulley and the second belt pulley are synchronous belt pulleys. In some embodiments, the output shaft of the first rotary driver 133 and the wheel shaft of the rotating wheel 132 can also be driven through a coupling, a chain transmission module or a gear transmission module, etc.

[0061] According to an embodiment of the present invention, as Figure 1 and Figure 2As shown in the figure, the driving mechanism 120 may include a frame 121, a rotating shaft 122, a second rotary driver 123, a first cam 1241, a first follower 1242, a first guiding pair 1243, a first driving wheel 1251, a second driving wheel 1261, a first driving rod 1253, and a second driving rod 1263. Among them, the frame 121 is used to provide support and installation positions for other components of the driving mechanism 120, and a receiving space is provided inside the frame 121. Optionally, the frame 121 may include a top plate, a bottom plate, and two side plates. Among them, the top plate is arranged directly above the bottom plate, and the two side plates are respectively connected between the top plate and the bottom plate. The rotating shaft 122 is arranged in the frame 121 along the first direction (i.e., arranged in the receiving space), and both ends of the rotating shaft 122 are pivotally connected to the side plates respectively, and one end of the rotating shaft 122 is connected to the output shaft of the second rotary driver 123. The second rotary driver 123 may be a motor, a reduction motor, etc., and the second rotary driver 123 can drive the rotating shaft 122 to rotate.

[0062] As Figure 1 and Figure 2 As shown in the figure, a plurality of first guiding pairs 1243 are provided. The plurality of first guiding pairs 1243 are respectively connected between the support plate 110 and the frame 121 to guide the lifting movement of the support plate 110, so that the lifting movement of the support plate 110 is smoother. Optionally, the first guiding pair 1243 includes a first guide rod and a first guide sleeve. Among them, the first guide rod is fixed to the lower side of the support plate 110, the first guide sleeve is installed on the top plate of the frame 121, and the first guide rod passes through the first guide sleeve and is in sliding fit with the first guide sleeve. The first cam 1241 is fixedly connected to the rotating shaft 122, the first follower 1242 is fixedly connected to the lower side of the support plate 110, and the lower end of the first follower 1242 extends into the frame 121 and abuts against the circumferential surface of the first cam 1241 (a hole for avoiding the first follower 1242 is provided on the top plate of the frame 121). When the second rotary driver 123 drives the rotating shaft 122 to rotate, the first cam 1241 rotates together with the rotating shaft 122. At this time, if the pushing stroke part of the first cam 1241 contacts the first follower 1242, the first cam 1241 will push the support plate 110 to move upward along the second direction through the first follower 1242; if the return stroke part of the first cam 1241 contacts the first follower 1242, the support plate 110 will move downward along the second direction under the action of gravity. Optionally, the first follower 1242 may be a roller follower, a flat-bottomed follower, a pointed follower, etc. For example Figure 1 and Figure 2 In the embodiments shown in the figure, the first follower 1242 adopts a roller follower, and the roller follower is in rolling contact with the first cam 1241, which is beneficial to reducing friction and wear, and at the same time improving the smoothness and reliability of the movement.

[0063] As Figure 1 andFigure 2 As shown, the first driving wheel 1251 and the second driving wheel 1261 are arranged on the rotating shaft 122 at intervals. A first driving groove 1252 is arranged on the circumferential side surface of the first driving wheel 1251, and a second driving groove 1262 is arranged on the circumferential side surface of the second driving wheel 1261. The first driving rod 1253 is connected to the lower side of a hemming mechanism 130, especially to the lower side of the carrier plate of the hemming mechanism 130. The lower end of the first driving rod 1253 extends into the frame 121 and is inserted into the first driving groove 1252 (a hole for avoiding the first driving rod 1253 is arranged on the top plate of the frame 121). The second driving rod 1263 is connected to the lower side of another hemming mechanism 130, especially to the lower side of the carrier plate 134 of the hemming mechanism 130. The lower end of the second driving rod 1263 extends into the frame 121 and is inserted into the second driving groove 1262 (a hole for avoiding the second driving rod 1263 is arranged on the top plate of the frame 121). When the second rotary driver 123 drives the rotating shaft 122 to rotate, the first driving wheel 1251 and the second driving wheel 1261 rotate together with the rotating shaft 122, and drive the two hemming mechanisms 130 to approach or move away from each other through the cooperation between the first driving rod 1253 and the first driving groove 1252, and the cooperation between the second driving rod 1263 and the second driving groove 1262.

[0064] According to an embodiment of the present invention, as Figure 1 and Figure 2 shown, the bundling device 100 may further include a pressure maintaining mechanism 140, and the pressure maintaining mechanism 140 is used to cooperate with the driving mechanism 120 to perform pressure maintaining on the waist seal after bundling, so that the waist seal is bonded more firmly.

The driving mechanism 120 is connected to the connecting frame 142 and is configured to drive the connecting frame 142 to move up and down in the second direction. Specifically, the driving mechanism 120 may further include a second cam 1271, a second follower 1272, and a plurality of second guiding pairs 1273. Among them, the second guiding pairs 1273 are connected between the connecting frame 142 and the support plate 110 to guide the up and down movement of the connecting frame 142, making the up and down movement of the connecting frame 142 smoother. Optionally, the second guiding pair 1273 includes a second guide rod and a second guide sleeve. Among them, the second guide rod is fixedly connected to the connecting frame 142, the second guide sleeve is installed on the support plate 110, and the second guide rod passes through the second guide sleeve and is slidably matched with the second guide sleeve. The second cam 1271 is fixedly connected to the rotating shaft 122, the second follower 1272 is fixedly connected to the connecting frame 142, and the lower end of the second follower 1272 extends into the frame 121 and abuts against the circumferential side surface of the second cam 1271 (holes for avoiding the second follower 1272 are provided on both the support plate 110 and the top plate of the frame 121). When the second rotary driver 123 drives the rotating shaft 122 to rotate, the second cam 1271 rotates together with the rotating shaft 122. At this time, if the pushing stroke part of the second cam 1271 contacts the second follower 1272, the second cam 1271 will push the connecting frame 142 to move upward in the second direction through the second follower 1272; if the return stroke part of the first cam 1241 contacts the second follower 1272, the connecting frame 142 will move downward in the second direction under the action of gravity. Optionally, the second follower 1272 may be a roller follower, a flat-bottom follower, a tip follower, etc. For example Figure 1 and Figure 2 in the embodiment shown, the second follower 1272 adopts a roller follower to reduce friction and wear, and improve the smoothness and reliability of the movement.
