[0002] At present, the cartoning machine is a device that integrates materials (blister tablets), instructions (paper tablet instructions), cartons, etc. into small packaging boxes, and then integrates multiple small packaging boxes and repackages them into medium packaging boxes (i.e., box-in-box). It involves the repackaging of various types of items such as food, medicine, and cosmetics, and has a large market demand space. Its card box chain distance adjustment device is an important component for conveying formed cartons on high-speed cartoning machines. It provides reliable left and right support for the carton. Under high-speed operation, the carton can be fixed without deformation. A complete set of card box chain distance adjustment devices includes four card box chains with T-type pushers and corresponding sprockets. The four chains are connected in pairs and can be applied to a certain range of width changes of carton specifications. However, the connection between the chain and the sprocket is a purely mechanical connection. Since it is inside the cartoning machine equipment, the debugging space is small. When switching carton specifications, the manual control of the distance adjustment is time-consuming, labor-intensive, troublesome, and inaccurate. This affects the overall production speed of the cartoning machine. Summary of the invention

[0005] Bearings are installed between the left outer passive sprocket and the left outer driving sprocket, between the left inner driving sprocket and the left inner passive sprocket, between the right outer driving sprocket and the right outer passive sprocket, and between the right inner passive sprocket and the right inner driving sprocket, so that one of the sprockets rotates while the other remains stationary. The main rotating power source and the pitch-adjusting rotating power source are both electrically connected to the motion controller, which is uniformly and accurately controlled by it.

[0006] The rear intermediate transmission assembly includes a reversing gear, a transverse transmission shaft, a main transmission gear, a main transmission shaft, and a synchronous transmission member connected in sequence.

[0008] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation modes.

[0009] Figure 1 It is a schematic diagram of the installation structure of the present invention. DETAILED DESCRIPTION

[0010] Reference Figure 1It can be seen that the double-controlled card box chain one-key spacing adjustment device of the present invention is applied to a high-speed cartoning machine, including a frame 27, a front transmission shaft 18, and a rear transmission shaft 9. The rear transmission shaft 9 is connected to a main rotating power source 1 (main servo motor) through a rear intermediate transmission component. A left outer passive sprocket 22 and a left outer driving sprocket 21 (at the left outer end), a left inner driving sprocket 19 and a left inner passive sprocket 20 (at the left inner end) are respectively installed on both ends of the front transmission shaft 18. A right outer driving sprocket 12 and a right outer driven sprocket 13 (at the right outer end), a right inner driven sprocket 11 and a right inner driving sprocket 10 (at the right inner end) are respectively installed on both ends of the rear transmission shaft 9. Between the left outer driven sprocket 22 and the right outer driving sprocket 12 They are connected by a right outer card box chain 24 (a right outer group), the left outer driving sprocket 21 and the right outer passive sprocket 13 are connected by a left outer card box chain 26 (a left outer group), the left inner driving sprocket 19 and the right inner passive sprocket 11 are connected by a left inner card box chain 25 (a left inner group), the left inner passive sprocket 20 and the right inner driving sprocket 10 are connected by a right inner card box chain 23 (a right inner group), the left outer card box chain 26, the right outer card box chain 24, the left inner card box chain 25, and the right inner card box chain 23 are all equipped with a plurality of T-shaped pushers 28 (each position corresponds to each other), and the front transmission shaft 18 is connected to the pitch-adjusting rotating power source 14 (a pitch-adjusting servo motor) through a front intermediate transmission assembly.

[0011] Bearings 29 are installed between the left outer passive sprocket 22 and the left outer driving sprocket 21, between the left inner driving sprocket 19 and the left inner passive sprocket 20, between the right outer driving sprocket 12 and the right outer passive sprocket 13, and between the right inner passive sprocket 11 and the right inner driving sprocket 10, so that one of the sprockets rotates while the other sprocket remains stationary. The main rotating power source 1 and the adjustable pitch rotating power source 14 are both electrically connected to the motion controller 30, which is precisely controlled by them. This motion controller 30 is specially designed for control with high precision requirements and high response sensitivity requirements in the field of motion control. It can realize interpolation control, accurately capture the position in real time, and correct it in time when a small deviation occurs, so as to realize closed-loop control and prevent the equipment from being misadjusted and colliding with the machine.

[0012] The rear intermediate transmission assembly includes a reversing gear 8, a transverse transmission shaft 7, a main transmission gear 6, a main transmission shaft 5, and a synchronous transmission member 4 connected in sequence. The reversing gear 8 is mounted on the outer end of the rear transmission shaft 9, and the synchronous transmission member 4 is connected to the main rotating power source 1. The front intermediate transmission assembly includes a pitch-adjusting transmission synchronous wheel 17, a pitch-adjusting synchronous belt 16, and a pitch-adjusting active synchronous wheel 15 connected in sequence. The pitch-adjusting transmission synchronous wheel 17 is mounted on the outer end of the front transmission shaft 18, and the pitch-adjusting active synchronous wheel 15 is connected to the pitch-adjusting rotating power source 14. The other end of the main transmission shaft 5 is connected to the coding device of the high-speed cartoning machine, and the other end of the reversing gear 8 is connected to the tongue-inserting device of the high-speed cartoning machine. Therefore, the main rotating power source 1 cannot be used as the pitch adjustment of each card box chain, otherwise it will affect the working accuracy of the coding device and the tongue-inserting device.

[0013] The working principle of the present invention is as follows: the power of the above-mentioned card box chains originally came from the main rotating power source 1, and now the power is separated, and the two left outer and right outer card box chains responsible for fixing the left side of the paper box and the two left inner and right inner card box chains responsible for fixing the right side of the paper box are driven by unused power respectively, that is, double power input control at both ends. That is: the power source on the right side is the main rotating power source 1 to drive the right outer and right inner card box chains, and the left side is newly added with a distance-adjusting rotating power source 14 to drive the left outer and left inner card box chains separately. After the power is separated, the card box chains on both sides can operate independently, and under normal operation, the card box chains on both sides operate synchronously. When adjusting the pitch, the main rotating power source 1 does not work, and the pitch adjusting rotating power source 14 realizes the pitch adjusting function, which drives the left outer driving sprocket 21, the left outer card box chain 26 and the right outer passive sprocket 13, the left inner driving sprocket 19, the left inner card box chain 25 and the right inner passive sprocket 11 in sequence through the front intermediate transmission assembly, thereby adjusting the distance between the pushers on the left outer card box chain 26 and the left inner card box chain 25, and the left outer passive sprocket 22, the right outer driving sprocket 12 and the right outer card box chain 24, the left inner passive sprocket 20, the right inner driving sprocket 10 and the right inner card box chain 23 remain fixed.
