Technical Field
[0001] This utility model relates to the field of packaging box printing technology, specifically a positioning device for printing pharmaceutical packaging boxes. Background Technology
[0002] Packaging boxes, as the name suggests, are boxes used to package products. They can be classified by material, such as: cardboard boxes, tin boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, corrugated packaging boxes, etc. The functions of packaging boxes include: ensuring the safety of products during transportation and enhancing the product's grade.
[0003] For example, Chinese patent application number 202323228422.8 discloses a positioning mechanism for packaging box printing, including a printing device body. A working groove is formed on one side of the upper end face of the printing device body, and a cavity is formed on one side of the inner wall of the working groove. A first drive motor is disposed inside the cavity. This positioning mechanism for packaging box printing is convenient for printing and easy to adjust. It solves the problem that most existing packaging box printing positioning mechanisms require manual adjustment of each packaging box to the appropriate position during printing, resulting in low work efficiency and high labor costs. It also solves the problem that most existing packaging box printing positioning mechanisms require adjustment of the entire device when changing packaging boxes, which is very troublesome and time-consuming.
[0004] However, the positioning mechanism for packaging box printing still has some shortcomings in actual use. For example, before the packaging box is transported to the printing station, it is easy for it to tilt or shift due to factors such as conveyor belt vibration and uneven conveying speed. The existing positioning device lacks an effective pre-sorting mechanism, which leads to a decrease in subsequent positioning accuracy and problems such as misalignment and cutting deviation in the printed pattern.
[0005] Meanwhile, the positioning spacing of traditional positioning devices is mostly fixed. When faced with packaging boxes of different specifications (with differences in length and width), the positioning components need to be replaced manually. This is not only cumbersome to operate, but also consumes a lot of downtime for adjustment, which seriously restricts production efficiency. Utility Model Content
[0006] The purpose of this invention is to provide a positioning device for printing pharmaceutical packaging boxes, so as to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, the present invention provides the following technical solution: a positioning device for printing pharmaceutical packaging boxes, comprising a frame assembly, wherein an adjustment component is fixedly embedded in the top center of the frame assembly, and a leveling component is provided on the front side of the frame assembly;
[0008] The adjustment assembly includes a vertical frame plate, a threaded vertical rod rotatably installed inside the vertical frame plate, a threaded slider slidably installed on the vertical frame plate, the threaded slider being threadedly sleeved on the rod body of the threaded vertical rod, transmission rods rotatably connected to both sides of the threaded slider, and a No. 1 servo motor fixedly installed on the top surface of the vertical frame plate, with one end of the output shaft of the No. 1 servo motor fixedly connected to the top end of the threaded vertical rod.
[0009] The leveling assembly includes two long strips, and a rotating shaft is rotatably mounted on the front of the two long strips. Two rotating baffle plates are fixedly mounted on the shaft. The two rotating baffle plates are symmetrically arranged. A second servo motor is fixedly mounted on the outer side of one of the long strips. One end of the output shaft of the second servo motor is fixedly connected to one end of the rotating shaft.
[0010] Preferably, the frame assembly includes a long frame plate, the top surface of which has an installation groove, and both sides of the long frame plate are fixedly fitted with installation baffles.
[0011] Preferably, two sliding columns are fixedly installed between the two mounting baffles, and hanging plates are slidably sleeved on the columns of the two sliding columns. Positioning plates are fixedly installed at the bottom ends of the two hanging plates on the same side, and positioning push plates are fixedly installed on the bottom front of the two positioning plates.
[0012] Preferably, elastic buffer plates are fixedly bonded to the inner sides of the positioning plate and the positioning push plate, and mounting ears are fixedly installed on the bottom of the outer sides of the two mounting baffles, with fixing bolts threaded into the top surfaces of the two mounting ears.
[0013] Preferably, the vertical frame plate is fixedly installed in the middle of the mounting groove, and the two long strip plates are respectively fixedly installed on the front of the two mounting baffles.
[0014] Preferably, the two transmission rods correspond one-to-one with the two positioning plates, and one end of the transmission rod is rotatably connected to the inner side of the positioning plate.
[0015] Compared with the prior art, the beneficial effects of this utility model are:
[0016] 1. This positioning device for printing pharmaceutical packaging boxes utilizes a linkage structure of adjusting components. A servo motor drives a threaded vertical rod to rotate, causing the threaded slider to rise and fall. This, in turn, adjusts the distance between the positioning plates on both sides synchronously via a transmission rod. This adjustment process requires no component replacement, allowing for rapid adaptation to pharmaceutical packaging boxes of different sizes, significantly shortening changeover time and improving production continuity. Simultaneously, the leveling component, driven by a second servo motor, rotates a platen to pre-align the packaging boxes during transport, correcting their tilt. Combined with the centering and pushing action of the positioning pusher, the packaging box can be precisely positioned in the middle of the conveyor belt, ensuring consistent printing pattern placement and reducing scrap rates.
[0017] 2. The elastic buffer plates on the inner sides of the positioning plate and the positioning push plate are made of rubber or silicone, which can ensure stable positioning pressure and avoid damage to the box caused by hard contact, reduce material waste and lower production costs.
[0018] 3. It integrates functions such as leveling, centering, and stable conveying, eliminating the need for additional auxiliary mechanisms, simplifying the layout of the printing production line, and reducing equipment purchase and maintenance costs. Attached Figure Description

[0025] like Figure 1-4 As shown, this utility model provides a technical solution: a positioning device for printing pharmaceutical packaging boxes, including a frame assembly 1, an adjustment component 2 fixedly embedded in the top center of the frame assembly 1, and a leveling component 3 provided on the front of the frame assembly 1.
[0026] The frame assembly 1 includes a long frame plate 101. A mounting groove 102 is formed on the top surface of the long frame plate 101. Mounting baffles 103 are fixedly mounted on both sides of the long frame plate 101. Two sliding columns 104 are fixedly mounted between the two mounting baffles 103. Hanging plates 105 are slidably sleeved on the columns of the two sliding columns 104. Positioning plates 106 are fixedly mounted on the bottom ends of the two hanging plates 105 on the same side. Positioning push plates 107 are fixedly mounted on the bottom front of the two positioning plates 106. Elastic buffer plates 108 are fixedly bonded to the inner surfaces of the positioning plates 106 and the positioning push plates 107. Mounting ears 109 are fixedly mounted on the bottom outer surfaces of the two mounting baffles 103. Fixing bolts 110 are threaded into the top surfaces of the two mounting ears 109.
[0027] The adjustment assembly 2 includes a vertical frame plate 201, which is fixedly installed in the middle of the mounting groove 102. A threaded vertical rod 202 is rotatably installed inside the vertical frame plate 201. A threaded slider 203 is slidably installed on the vertical frame plate 201. The threaded slider 203 is threadedly sleeved on the rod body of the threaded vertical rod 202. Both sides of the threaded slider 203 are rotatably connected to transmission rods 204. The two transmission rods 204 correspond one-to-one with the two positioning plates 106. One end of the transmission rod 204 is rotatably connected to the inner side of the positioning plate 106. A first servo motor 205 is fixedly installed on the top surface of the vertical frame plate 201. One end of the output shaft of the first servo motor 205 is fixedly connected to the top end of the threaded vertical rod 202.
[0028] The leveling assembly 3 includes two long strips 301, which are fixedly installed on the front of two mounting baffles 103 respectively. A rotating shaft 302 is rotatably installed at the front between the two long strips 301. Two rotating baffle plates 303 are fixedly installed on the shaft of the rotating shaft 302. The two rotating baffle plates 303 are symmetrically arranged. A second servo motor 304 is fixedly installed on the outer side of the long strip 301 on one side. One end of the output shaft of the second servo motor 304 is fixedly connected to one end of the rotating shaft 302.
[0029] Working principle: In use, the positioning device is fixed to the printing equipment by mounting ear 109 and fixing bolt 110. According to the size of the medicine packaging box, the first servo motor 205 is started. The first servo motor 205 drives the threaded vertical rod 202 to rotate, and the threaded slider 203 slides on the threaded vertical rod 202. Through the transmission rod 204, the positioning plate 106 is driven to slide on the slide column 104, and the distance between the positioning plates 106 is adjusted to the appropriate position.
[0030] During the transport of the pharmaceutical packaging boxes, servo motor 304 is activated, driving shaft 302 to rotate, causing rotating baffle plate 303 to rotate to a suitable angle to level the packaging boxes. When the packaging boxes on the conveyor belt reach the position of rotating baffle plate 303, they become straight under the action of rotating baffle plate 303. Then, servo motor 205 is activated, causing two positioning push plates 107 to move closer together, thus pushing the straightened packaging boxes to the middle of the conveyor belt for centering. Then, servo motor 304 is activated, and under the action of servo motor 304, rotating baffle plate 303 rotates to a horizontal state. The packaged boxes, now leveled between the two positioning push plates 107, are then transported between positioning plates 106. Positioning push plates 107 precisely position the boxes for printing operations, while positioning plates 106 transport and position them for stable transport.
