Description

Technical Field

[0001] This utility model relates to the field of boxing technology, and in particular to a tongue-pressing structure for aluminum-plastic composite boxing. Background Technology

[0002] With the popularization of automated production equipment, more and more pharmaceutical companies are using automatic cartoning machines for drug packaging. The specific process of cartoning is to first transfer the aluminum-plastic sheet from the conveyor belt to the product chain, then prepare the cardboard box, and then push the aluminum-plastic sheet into the cardboard box and perform the tongue pressing work.

[0003] Chinese patent application No. 202020735340.X, filed on May 7, 2020, discloses a mechanical tongue depressor mechanism for a cartoning machine, comprising: a base; an elastic telescopic mechanism vertically disposed at the bottom of the base; and a zigzag pressure plate disposed at the bottom end of the elastic telescopic mechanism; wherein, the zigzag pressure plate is pressed against an aluminum-plastic plate below it under the action of the elastic telescopic mechanism, and the elastic telescopic mechanism comprises: a sliding rod, the upper end of which is connected to the base; and a telescopically disposed at the lower end of the sliding rod. The telescopic rod has a zigzag pressure plate connected to its bottom end, and a set of return springs on the telescopic rod. The slight tail-lifting phenomenon that occurs at the tail end of the aluminum-plastic sheet during the boxing process of the mechanical tongue-pressing mechanism of this cartoning machine coincides with the pushing action of the mechanical push rod, creating a drop that facilitates the smooth pushing of the aluminum-plastic sheet into the box. This avoids the problem of damage to packaging materials caused by the skipping or dragging of aluminum-plastic sheets during the boxing process, and reduces the loss of aluminum-plastic sheets, instruction manuals, and cardboard boxes. However, it still has the following drawbacks:

[0004] In the aforementioned comparative documents, the pressure plate is set in the corresponding track, and the width of the pressure plate is also fixed. When the width of the aluminum-plastic plate used to press the tongue is smaller than the width of the pressure plate, the aluminum-plastic plate cannot be positioned by the track and is prone to displacement under the push of the push rod. Once the pushed aluminum-plastic plate is displaced, it will affect the feeding.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this patent application and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a tongue-pressing structure for packaging aluminum-plastic composite panels, including a tongue-pressing plate and a telescopic mechanism. The tongue-pressing plate has two openings along its horizontal direction, and the two openings are symmetrically distributed on both sides of the telescopic mechanism. A mounting frame is fixed to the tongue-pressing plate corresponding to the openings. A storage space is provided below the tongue-pressing plate corresponding to the openings.

[0010] Preferably, the mounting bracket has sliding holes on both the front and back sides, the connecting rod is longitudinally disposed in the sliding holes, the connecting rod is slidably connected to the inside of the sliding holes, one end of the connecting rod passes through and extends to the outside of the corresponding sliding hole, and a threaded groove is formed on the outer periphery of the connecting rod corresponding to the end, a nut is threadedly connected to the threaded groove, the nut abuts against the outside of the mounting bracket, and a baffle is fixed to the end of the connecting rod away from the nut, the baffle abuts against the outside of the mounting bracket.

[0011] Preferably, the length of the sliding hole is equal to the length of the inner cavity of the mounting bracket, the diameter of the connecting rod is adapted to the height of the sliding hole, and the connecting rod moves linearly left and right within the sliding hole.

[0012] Preferably, the positioning plate moves linearly left and right within the mounting frame, and the width of the positioning plate is adapted to the width of the inner cavity of the mounting frame.

[0013] Preferably, an extension plate is hinged to the upper end face of the positioning plate near the telescopic mechanism via a hinge shaft. The extension plate abuts against the upper end face of the positioning plate. A rotating shaft is fixed to the side of the positioning plate away from the telescopic mechanism. A limiting plate is rotatably connected to the outer side of the rotating shaft. The limiting plate abuts against the side of the positioning plate and the extension plate away from the telescopic mechanism.

[0014] Preferably, the extension plate is a U-shaped plate, the groove is connected to the interior of the extension plate, and the length and width of the positioning plate are equal to the length and width of the extension plate, respectively.

[0015] Preferably, a placement groove is provided on the upper surface of one of the mounting brackets near its left and right sides, and the extension plate and the positioning plate are slidably connected in the placement grooves on the left and right sides respectively.

[0016] Preferably, the positioning plate abuts against the right side wall of the right side placement slot, and the left side of the extension plate has an movable gap with the left side wall of the left side placement plate.

[0017] The present invention adopts the above technical solution and has the following technical effects compared with the prior art:

[0018] (1) The tongue-pressing structure for aluminum-plastic composite box packaging can position materials with a width smaller than the tongue-pressing plate by setting a positioning plate and mounting frame, so as to avoid the subsequent external push rod from deviating when pushing the material. This solves the problem that materials with a width smaller than the tongue-pressing plate cannot be positioned by the track, resulting in low material feeding accuracy.

[0019] (2) The tongue-pressing structure for aluminum-plastic composite board packaging can drive the positioning plate to move within the mounting frame via the connecting rod, so as to adapt to the width of different materials. The extension plate added to the positioning plate can adapt to the height of multi-layer stacked materials. At the same time, when pushing and pressing the material normally, the positioning plate can be retracted through the placement slot, thereby improving the practicality of the tongue-pressing structure.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0029] Example 1:

[0030] Please see Figure 1-5 This embodiment provides a tongue-pressing structure for packaging aluminum composite panels, including a tongue-pressing plate 3 and a telescopic mechanism 4. The tongue-pressing plate 3 has two horizontal openings 2, which are symmetrically distributed on both sides of the telescopic mechanism 4. A mounting frame 5 is fixed on the tongue-pressing plate 3 corresponding to the openings 2. A storage space is provided below the tongue-pressing plate 3 corresponding to the openings 2. The mounting frame 5, the openings 2, and the storage space are connected sequentially from top to bottom. A positioning plate 6 is provided in the mounting frame 5 along the vertical direction. The positioning plate 6 is set in the mounting frame 5 through the moving unit. The bottom surface of the positioning plate 6 passes through the openings 2 and extends into the storage space.

[0031] In application, after placing the material that cannot be positioned on the track under the pressure plate, the positioning plate 6 is first moved within the mounting frame 5, the opening 2, and the storage space by the moving unit, and the positioning plate 6 is moved to abut against both sides of the material. After the positioning plate 6 has abutted, the moving unit fixes the positioning plate 6. At this time, it is pushed into the carton by the external push rod. During the pushing process, the positioning plate 6 can limit the pushing direction of the material to avoid deviation. After the pushing is completed, the material can be pressed by the tongue plate 3 and the telescopic mechanism 4.

[0032] Example 2:

[0033] The basic content is the same as in Example 1, except that:

[0034] Please see Figure 1-3In this embodiment, one of the moving units includes a connecting rod 8, which is longitudinally arranged within the mounting frame 5. A sliding groove 12 is provided inside the positioning plate 6, and the positioning plate 6 is slidably inserted into the outside of the connecting rod 8 via the sliding groove 12. The diameter of the connecting rod 8 is adapted to the width of the sliding groove 12. The positioning plate 6 moves linearly on the connecting rod 8 via the sliding groove 12. Sliding holes 1 are provided laterally on both the front and back sides of the mounting frame 5. The connecting rod 8 is longitudinally arranged within the sliding holes 1 and slidably connected inside the sliding holes 1. One end of the connecting rod 8 passes through and extends to the corresponding sliding hole 1. On the outer side of the mounting bracket 5, a threaded groove 9 is provided on the outer periphery of the connecting rod 8 corresponding to the end. A nut 10 is threadedly connected to the threaded groove 9. The nut 10 abuts against the outer side of the mounting bracket 5. A baffle 15 is fixed to the end of the connecting rod 8 away from the nut 10. The baffle 15 abuts against the outer side of the mounting bracket 5. The length of the sliding hole 1 is equal to the length of the inner cavity of the mounting bracket 5. The diameter of the connecting rod 8 is adapted to the height of the sliding hole 1. The connecting rod 8 moves linearly left and right in the sliding hole 1. The positioning plate 6 moves linearly left and right in the mounting bracket 5. The width of the positioning plate 6 is adapted to the width of the inner cavity of the mounting bracket 5.

[0035] In application, rotate nut 10 to release it from locking the positioning plate 6. Nut 10 and baffle 15 can then release their contact with the mounting bracket 5. At this time, connecting rod 8 can move within sliding hole 1. When connecting rod 8 moves, it can drive positioning plate 6 to move, so that positioning plate 6 can adapt to the width of different materials. Then rotate nut 10 in the opposite direction. Through the cooperation of nut 10 and baffle 15, positioning plate 6 and connecting rod 8 can be positioned.

[0036] Example 3:

[0037] The basic content is the same as in Example 1, except that:

[0038] Please see Figure 4 In this embodiment, the upper end face of the positioning plate 6 near the telescopic mechanism 4 is hinged to an extension plate 11 via a hinge shaft. The extension plate 11 abuts against the upper end face of the positioning plate 6. A rotating shaft 14 is fixed on the side of the positioning plate 6 away from the telescopic mechanism 4. A limiting plate 13 is rotatably connected to the outer side of the rotating shaft 14. The limiting plate 13 abuts against the side of the positioning plate 6 and the extension plate 11 away from the telescopic mechanism 4. The extension plate 11 is a U-shaped plate. The sliding groove 12 is connected to the interior of the extension plate 11. The length and width of the positioning plate 6 are equal to the length and width of the extension plate 11, respectively.

[0039] When there is too much material reserved under the tongue depressor 3, the positioning plate 6 and the extension plate 11 can be matched to accommodate the height of the reserved material. When assembling the extension plate 11 and the positioning plate 6, rotate the extension plate 11 so that the extension plate 11 and the positioning plate 6 abut vertically, and then rotate the limiting plate 13 so that the limiting plate 13 abuts against the positioning plate 6 and the extension plate 11. The assembly of the extension plate 11 and the positioning plate 6 is then completed.

[0040] Example 4:

[0041] The basic content is the same as in Example 1, except that:

[0042] Please see Figure 5 In this embodiment, one of the mounting brackets 5 has a placement groove 7 on the upper surface near its left and right sides. The extension plate 11 and the positioning plate 6 are slidably connected in the placement grooves 7 on the left and right sides respectively. The positioning plate 6 abuts against the right side wall of the right placement groove 7. There is an movable gap between the left side of the extension plate 11 and the left side wall of the left placement plate.

[0043] When in use, the positioning plate 6 and the extension plate 11 need to be retracted when the tongue depressor 3 is in normal use. When retracting, first rotate the positioning plate 6 so that the positioning plate 6 moves into the right placement slot 7, and then flip the extension plate 11 so that the extension plate 11 moves into the left placement slot 7. Then rotate the limiting plate 13 so that the positioning plate 6 and the extension plate 11 can be assembled and stored in the placement slot 7.
