Description

Technical Field

[0001] The utility model relates to the technical field of paper printing and processing, in particular to a blanking device for a saddle stitcher. Background Art

[0002] The saddle stitcher is a binding line that belongs to printing and processing machinery. Its processing steps include collating, saddle stitching, and cutting the finished products into rows at one time. The binding method is saddle stitching. After the product is printed and folded, it is placed in the saddle stitcher and processed into a finished product through the assembly line. It is generally used for the binding process of large quantities of books and magazines.

[0003] After searching, it was found that a saddle stitching dragon blanking device was disclosed in the utility model patent with the Chinese patent publication number CN213622409U. The saddle stitching dragon blanking device in the utility model patent is convenient for users to adjust the feeding height of the whole device according to their needs by adjusting the length of the telescopic rod, and a rotatable and adjustable conveying plate is provided to facilitate the paper finished product to be connected to the conveyor belt inside the device for conveying and unloading. However, the saddle stitching dragon blanking device guides the conveying direction through a rotatable guide wheel. Combined with the structure of the guide wheel, it can be seen that the distance between the guide wheels on both sides is fixed, that is, it is not convenient to cut off the paper. The spacing is adjusted according to the size of the finished paper product, and it is impossible to ensure that the guide wheel can fit the side of paper products of different sizes for rolling guidance. At the same time, the saddle stitch dragon unloading device pushes the pressure wheel down through the telescopic gas rod to press the paper surface. Combined with the pressure wheel structure, it can be seen that the pressure wheel and the rotating rod structure do not have an upper and lower buffer structure. When the telescopic gas rod pushes the pressure wheel down too much, it is easy to form a wheel-shaped indentation on the paper surface, which affects the flatness qualification rate of the paper product. Therefore, the feeding guide structure and paper leveling structure of the saddle stitch dragon unloading device need to be further improved. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figure 1-7 A material unloading device for a riding stitching dragon comprises a conveyor platform 1, a guide flat pressing structure 2 is provided on the top of the conveyor platform 1, two belt rollers are rotatably connected to the inner side of the conveyor platform 1, a servo motor 4 drives one of the belt rollers, and the outer sides of the two belt rollers are connected to a conveyor belt 3, and the two belt rollers rotate synchronously through the transmission conveyor belt 3, and a servo motor 4 is fixedly installed on the front side of the conveyor platform 1.

[0026] The guide and flattening structure 2 includes a side plate 201 fixed to the top of the conveying platform 1. The inner side of the side plate 201 is rotatably connected to an adjusting screw 202. The first and second rotating rods are rotated to rotate the four adjusting screws 202. The external threads of the adjusting screws 202 are connected to a translation seat 203. The adjusting screws 202 drive the translation seat 203 to move back and forth. The external side of the translation seat 203 is fixedly connected to a pressure plate 204. A buffer assembly 205 is provided on the inner side of the pressure plate 204. A guide wheel group 206 is provided on the outside of the pressure plate 204. The guide wheel group 206 is provided on the outer side of the pressure plate 204. The group 206 is connected to the pressure plate 204 through the buffer component 205, which can achieve the flexible limiting effect of the guide wheel group 206. The top of the side plate 201 is fixedly connected to the mounting frame 207, and the inner side of the mounting frame 207 is provided with a lifting seat 208. The rotating adjustment rod drives the eccentric wheel 210 to rotate through the pulley structure. The inner side of the lifting seat 208 is provided with a leveling cylinder 209. The eccentric wheel 210 drives the connecting rod to rotate eccentrically, so that the lifting seat 208 drives the leveling cylinder 209 to adjust up and down. The inner side of the mounting frame 207 is rotatably connected with the eccentric wheel 210.

[0027] according to Figure 3 and Figure 6 as well as Figure 7 As shown, the servo motor 4 drives one of the belt rollers through 1, and the two belt rollers are connected through the conveyor belt 3, so that the conveyor belt 3 transmits the material in the right direction, and rotates the first rotary rod and the second rotary rod on the two side plates 201 according to the size of the paper. The two adjusting screws 202 rotate synchronously through the two No. 1 pulleys, and the other two adjusting screws 202 rotate synchronously through the two No. 2 pulleys. The four adjusting screws 202 respectively drive the two translation seats 203 to move back and forth along the outer sides of the first screw rod and the second screw rod for adjustment, so as to facilitate the adjustment of the distance between the pressure plates 204 on both sides and the guide wheel group 206 according to the paper size, and limit the front and back sides of the paper.

[0028] according to Figure 6 and Figure 7 As shown, pointer pieces are fixedly connected to the left sides of the two translation seats 203. The two pointer pieces respectively pass through the sliding grooves on the left sides of the two side plates 201 and slide in contact with the two scale plates respectively, so as to conveniently and intuitively display the adjustment distance of the pressure plate 204 and the guide wheel group 206. At the same time, a support rod 2053 is hinged on one side of the guide wheel group 206, and a sliding rod 2051 is fixed in the U-shaped groove on the inner side of the pressure plate 204. A buffer spring 2052 is fixed to the top and bottom of the sliding rod 2051, and a slider is slidably connected to the outside of the sliding rod 2051, and the slider is fixed to one side of the buffer spring 2052.

[0029] according to Figure 6 and Figure 7As shown, one side of the support rod 2053 is hinged to the slider. When the guide wheel group 206 is adjusted to move to the side of the paper product, the paper is used to apply a reaction force to the support rod 2053 and push the slider to move to the side of the buffer spring 2052. The buffer spring 2052 elastically deforms to apply a flexible supporting force to the guide wheel group 206, which facilitates the guide wheel group 206 to achieve a flexible limiting effect on the side of the paper product. At the same time, the roller structure of the guide wheel group 206 can provide a guiding effect for paper transportation.

[0030] according to Figure 3 and Figure 5 As shown, the rotating adjustment rod synchronously drives the two eccentric wheels 210 through the third and fourth pulleys. The two eccentric wheels 210 are rotatably connected to the front and rear sides of the lifting seat 208 through the connecting rod, which facilitates the lifting seat 208 to move up and down and adjust the distance between the leveling cylinder 209 and the paper below. At the same time, the telescopic rod on the top of the lifting seat 208 is slidably connected to the sleeve on the inner top wall of the mounting frame 207, and the telescopic rod is used to provide a guide support for the lifting seat 208.

[0031] according to Figure 3 and Figure 5 As shown, the internal rotation of the flattening cylinder 209 is connected to a shaft, and the front and rear ends of the shaft are respectively connected to the outside of the two spring rods for sliding connection. When the flattening cylinder 209 rolls the paper, the paper will provide an upward reaction force for the flattening cylinder 209, so that the shaft drives the flattening cylinder 209 to slide up and down outside the spring rods. The spring structure outside the spring rods provides a buffering rolling effect for the flattening cylinder 209, thereby avoiding the situation where indentations are generated due to excessive downward pressure.

[0032] The working principle of the present invention is as follows: the unloading device of the riding stitching dragon connects the processed paper products to the left area of the conveyor belt 3 through the conveyor platform 1, and uses the servo motor 4 to drive the belt roller to the right transmission conveyor belt 3 for feeding. At this time, according to the size of the product, the first rotary rod and the second rotary rod of the two side plates 201 are rotated respectively, and the translation seat 203 is driven to move back and forth by adjusting the screw 202, and the spacing between the pressure plates 204 on both sides and the guide wheel group 206 is adjusted. The guide wheel group 206 is connected to the outside of the sliding rod 2051 through the support rod 2053 and the slider, and the buffer spring 20 is used to adjust the distance between the two side plates 204 and the guide wheel group 206. The elastic deformation of 52 performs flexibly limiting and guiding the side of the product, rotating the adjusting rod on the mounting frame 207, and the adjusting rod synchronously drives the two eccentric wheels 210 to rotate through the third pulley and the fourth pulley, and the eccentric wheel 210 drives the connecting rod to rotate eccentrically, so that the lifting seat 208 is lifted and lowered under the guidance and support of the telescopic rod and the sleeve, and the distance between the flattening cylinder 209 and the product below is adjusted. The flattening cylinder 209 is used to roll and contact the surface of the product, and the flattening cylinder 209 can slide up and down on the outside of the spring rod through the shaft rod, so as to facilitate the buffering and rolling of the paper surface and avoid the situation where the pressure is too high and the pressure causes indentations.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
