Description

Technical Field

[0001] This utility model relates to the field of product packaging, and in particular to a device for changing the distance in pen-shaped products. Background Technology

[0002] In the field of product packaging, especially in fully automated packaging processes, multiple machines typically need to work together to complete a series of complex procedures. From material supply, positioning and alignment, filling, sealing to labeling and palletizing, each step may be handled by different specialized equipment. Furthermore, the flow and connection of products between these machines often involve changes in posture and arrangement.

[0003] Taking pen-shaped products—such as pens, lipsticks, e-cigarettes, syringes, and injection pens—as an example, their unique shape often necessitates posture changes during transport between different devices. For instance, in the initial material handling or inspection stages, products may be transported at high speed in an "upright" posture for easy visual inspection or orientation correction; however, when entering a cartoning or wrapping machine, they may need to be arranged horizontally to adapt to the structure of the feeding channel. Furthermore, the required spacing (pitch) between products often differs between devices: the material handling section may have a denser arrangement to improve efficiency, while the cartoning station requires a specific spacing to ensure that the robotic arm or push rod has sufficient time and space to perform gripping actions.

[0004] This difference in posture and pitch makes it impossible for a single continuous conveyor to ensure smooth operation of the entire production line. Without an effective transition mechanism, product blockage, tipping, material spillage, or inaccurate positioning can easily occur, leading to downtime or even product damage. Therefore, a highly efficient and reliable "intermediate pitch transition device" must be configured between each piece of equipment—acting as a "coordination hub" of the production line, it can dynamically adjust the posture and spacing of the products to achieve a smooth and precise transition between different workstations, thereby ensuring the continuous, stable, and efficient operation of the entire packaging process. Utility Model Content

[0005] The purpose of this utility model is to provide a pen-shaped product spacing adjustment device that can quickly adjust the processing spacing of pen-shaped products and ensure the stability of pen-shaped products during rapid spacing changes.

[0006] To solve the above-mentioned technical problems, this utility model provides a pitch-changing device for pen-shaped products, including a frame, a pitch-changing mechanism located on the frame, and a drive mechanism for driving the pitch-changing mechanism to perform pitch-changing actions. The pitch-changing mechanism includes a slider guide shaft, a plurality of sliders movably disposed on the slider guide shaft, and a slide plate movably disposed on the frame. The sliders are provided with placement slots for supporting the pen-shaped body, and the slide plate is provided with a pitch-changing slot group. The pitch-changing slot group includes a plurality of pitch-changing slots that correspond one-to-one with the sliders, and the distance between adjacent pitch-changing slots gradually increases from one end of the pitch-changing slot to the other end.

[0007] Furthermore, a cam is rotatably connected to the bottom of the slider, and the cam is engaged in a pitch groove so that when the slide moves, the cam rolls along the trajectory of the pitch groove.

[0008] Furthermore, a suction cup is provided inside the placement groove, and an air pipe connected to the suction cup is connected to the side of the slider. One end of the air pipe is connected to the air distribution block so that the air distribution block can perform negative pressure suction on several air pipes.

[0009] Furthermore, the skateboard is detachably connected to the base, and the base is movably mounted on the skateboard guide shaft on the frame so that when the base moves along the skateboard guide shaft, it drives the skateboard to move synchronously.

[0010] Furthermore, a fixed frame is rotatably connected to the frame, and the slider guide shaft is connected to the fixed frame. One end of the fixed frame is hinged to the frame, and the other end is detachably connected to the frame through a locking block, so that when the fixed frame is flipped relative to the frame, the slide is in a maintenance state.

[0011] Furthermore, the drive mechanism includes a fixed plate located on the frame and a timing belt rotatably connected to the side of the fixed plate. A connecting plate is provided on the side of the base away from the slide plate. The connecting plate abuts against one side of the timing belt. A pressure plate is fixed on the connecting plate and abuts against the other side of the timing belt, so that the connecting plate and the pressure plate together clamp the timing belt.

[0012] Furthermore, the drive mechanism also includes a drive wheel and a driven wheel rotatably connected to the side of the fixed plate, a timing belt is sleeved on the drive wheel and the driven wheel, and the side of the fixed plate has a drive component for driving the drive wheel to rotate.

[0013] The beneficial effects of this utility model are as follows: the sliding plate drives the variable pitch groove group to move, so that the sliders corresponding to each variable pitch groove move horizontally along the trajectory of the variable pitch groove. Since the distance between adjacent variable pitch grooves gradually increases from one end of the variable pitch groove to the other end, the distance between adjacent sliders can be expanded or reduced simultaneously, realizing the automatic variable pitch arrangement of pen-shaped products. Moreover, since the slider moves along the slider guide shaft, the distance between adjacent sliders is adjusted only in the same horizontal direction, and there will be no problem of sliders shifting or intersecting.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0023] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as a limitation of this utility model.

[0024] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0025] like Figures 1-7 The present invention provides a pitch-changing device for pen-shaped products, including a frame 1, a pitch-changing mechanism 3 located on the frame 1, and a drive mechanism 2 for driving the pitch-changing mechanism 3 to perform pitch-changing actions. The pitch-changing mechanism 3 includes a slider guide shaft 31, a plurality of sliders 32 movably disposed on the slider guide shaft 31, and a slide plate 33 movably disposed on the frame 1. The sliders 32 are provided with placement grooves 34 for supporting pen-shaped products, and the slide plate 33 is provided with a pitch-changing groove group. The pitch-changing groove group includes a plurality of pitch-changing grooves 35 corresponding one-to-one with the sliders 32, and the distance between adjacent pitch-changing grooves 35 gradually increases from one end of the pitch-changing groove 35 to the other end.

[0026] The sliding plate drives the variable pitch slot group to move, so that the sliders corresponding to each variable pitch slot move horizontally along the trajectory of the variable pitch slot. Since the distance between adjacent variable pitch slots gradually increases from one end of the variable pitch slot to the other end, the distance between adjacent sliders can be expanded or reduced simultaneously, realizing the automatic variable pitch arrangement of pen-shaped products. Moreover, since the sliders move along the slider guide shaft, the distance between adjacent sliders is adjusted only in the same horizontal direction, and there will be no problem of sliders shifting or intersecting.

[0027] In one embodiment of this solution, two slider guide shafts are provided to guide and support several sliders together; the placement groove is arranged in an arc shape to adapt to the outer wall shape of the pen-shaped product.

[0028] Preferably, the bottom of the slider 32 is rotatably connected to a cam 36, which is engaged in a pitch groove 35 so that when the slide plate 33 moves, the cam 36 rolls along the trajectory of the pitch groove 35.

[0029] Specifically, when the slider and the variable pitch groove are linked, the relative position of the slider is affected by the trajectory of the variable pitch groove through the engagement of the cam and the variable pitch groove. When the slide moves, the cam rolls along the trajectory of the variable pitch groove, thereby driving the slider to move horizontally on the slider guide shaft, so as to realize the synchronous adjustment of the distance between adjacent sliders.

[0030] The direction of movement of the skateboard is perpendicular to the direction of movement of the slider.

[0031] Preferably, a suction cup 37 is provided inside the placement groove 34, and an air pipe 38 communicating with the suction cup 37 is connected to the side of the slider 32, and one end of the air pipe 38 is connected to the air distribution block 39 so that the air distribution block 39 performs negative pressure suction on several air pipes 38.

[0032] Specifically, when the pen-shaped product is placed in the placement slot, the air distribution block synchronously draws negative pressure from several air tubes, so that the air tubes provide negative pressure suction to the suction cup, and then the suction cup adsorbs and fixes the outer wall of the pen-shaped product, ensuring that the pen-shaped product remains stable during the change of distance.

[0033] The suction cup can be made of materials such as rubber. Due to the softness and deformability of rubber, the suction cup can closely fit the outer contour of the pen-shaped product when adsorbing it, ensuring stable adsorption.

[0034] In one embodiment of this solution, the gas distribution block is connected to an external negative pressure device via a pipeline to ensure that the suction cup position has sufficient negative pressure suction.

[0035] Preferably, the slide plate 33 is detachably connected to the base 310, and the base 310 is movably mounted on the slide plate guide shaft 314 on the frame 1 so that when the base 310 moves along the slide plate guide shaft 314, it drives the slide plate 33 to move synchronously.

[0036] Specifically, when the skateboard needs to be moved, the base moves linearly along the skateboard's guide axis, thereby driving the skateboard to move synchronously and achieving variable pitch transmission. The base and skateboard are detachably connected, facilitating future maintenance and replacement to adapt to different variable pitch requirements.

[0037] The skateboard can be connected to the base by means of bolts or other methods, thus ensuring the skateboard's detachable and replaceable function.

[0038] Preferably, a fixed frame 311 is rotatably connected to the frame 1, and a slider guide shaft 31 is connected to the fixed frame 311. One end of the fixed frame 311 is hinged to the frame 1, and the other end is detachably connected to the frame 1 through a locking block 312, so that when the fixed frame 311 is flipped relative to the frame 1, the slide plate 33 is in a maintenance state.

[0039] Specifically, the fixed frame supports the slider guide shaft and the various sliders connected to it, and the fixed frame is locked to the frame by the locking block to ensure that the slider does not shake during operation. When it is necessary to replace or maintain the trajectory of the pitch groove, the locking block can be unlocked, and the fixed frame, together with the slider guide shaft and the slide plate, can be flipped over to expose the pitch groove area, making it easy for operators to quickly inspect or replace the corresponding parts.

[0040] The locking block is connected to the frame, and the fixed frame has a locking hole at the position opposite to the locking block. Bolts and other connecting parts pass through the locking hole and are connected to the locking block to lock and position the fixed frame.

[0041] Preferably, the drive mechanism 2 includes a fixed plate 21 disposed at the frame 1 and a timing belt 22 rotatably connected to the side of the fixed plate 21. A connecting plate 313 is disposed on the side of the base 310 away from the slide plate 33. The connecting plate 313 abuts against one side of the timing belt 22. A pressure plate 23 is fixed on the connecting plate 313 and abuts against the other side of the timing belt 22, so that the connecting plate 313 and the pressure plate 23 together clamp the timing belt 22.

[0042] Specifically, the reciprocating rotation of the timing belt causes the connecting plate and the pressure plate to move synchronously with the timing belt, which in turn drives the base to move back and forth along the skateboard guide axis, thus achieving precise pitch change of the skateboard.

[0043] The connecting plate and the pressure plate can be connected by bolts, so that the connecting plate and the pressure plate tightly clamp the synchronous belt, ensuring the stable transmission of the synchronous belt to the connecting plate.

[0044] Preferably, the drive mechanism 2 further includes a drive wheel 24 and a driven wheel 25 rotatably connected to the side of the fixed plate 21, a timing belt 22 is sleeved on the drive wheel 24 and the driven wheel 25, and the side of the fixed plate 21 has a drive member 26 for driving the drive wheel 24 to rotate.

[0045] Specifically, after the drive unit is started, the output end of the drive unit drives the drive wheel to rotate, which drives the synchronous belt to run smoothly between the drive wheel and the driven wheel, thereby driving the connecting plate and the pressure plate to move back and forth along the side of the fixed plate.

[0046] The driving components include a drive motor and a reducer. The output end of the reducer is connected to the shaft of the drive wheel to adjust the output speed and torque.

[0047] This utility model is not limited to the above-described preferred embodiments. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this utility model.
