Description

Technical Field

[0001] This utility model relates to the field of cosmetic packaging technology, and in particular to an adjustable and detachable cosmetic box pushing structure. Background Technology

[0002] Transparent film (transparent paper) 3D packaging machines are mainly suitable for the automatic outer packaging of single or multiple (collective packaging) boxed items in industries such as pharmaceuticals, food, health products, tea, cosmetics, gifts, stationery, and audio-visual products. They provide anti-counterfeiting, moisture-proof, and dust-proof functions, while also enhancing the product's perceived quality. They can also be equipped with anti-counterfeiting pull lines. Currently, high-speed transparent film packaging machines use a conveyor to transport the packaging box to the demolding mechanism. After the transparent film is wrapped, the packaging box is rotated out by a transfer tower and pushed by a conveyor to complete the heat sealing of the transparent film.

[0003] Transparent film three-dimensional packaging machines have the following drawbacks:

[0004] 1. Complex structure and high maintenance cost: The push structure is rigidly fixed to the body without independent disassembly design. When subsequent component failures are repaired, a large number of related structures need to be disassembled, which is difficult to operate and can easily cause damage to other components, indirectly increasing the operation and maintenance cost.

[0005] 2. Poor specification adaptability: The pusher structure is a single fixed-size design, and the pusher plate spacing, pusher stroke, and pusher plate height cannot be adjusted. When packaging boxes of different lengths, widths, and heights, the entire pusher structure component needs to be replaced, which not only increases the cost of spare parts but also leads to a long specification changeover process, seriously affecting production continuity.

[0006] 3. Unstable pushing due to air pressure fluctuations: Due to factors such as air source pressure fluctuations and pipeline losses, the cylinder output thrust often varies greatly. When the thrust is too large, the box body and the pushing component collide rigidly, which can easily cause deformation of the box body or scratches on the surface; when the thrust is insufficient, the box may not be pushed in place, affecting the connection of subsequent processes. This unstable pushing directly reduces the consistency of product quality.

[0007] In summary, existing cosmetic box push structures are inadequate in terms of coping with air pressure fluctuations, adapting to multiple product specifications, and improving durability. There is an urgent need for a push structure that combines adjustability and buffering to solve the problems of unstable product quality and short equipment lifespan. Utility Model Content

[0008] The purpose of this invention is to provide an adjustable and detachable cosmetic box pushing structure to overcome the shortcomings of existing technologies. This structure, through improved design of the feeding and pushing devices, achieves stable conveying and precise pushing of cosmetic boxes, while also possessing good adjustability and cushioning performance, adapting to products of different specifications and extending the service life of the equipment.

[0009] To achieve the above objectives, this utility model provides an adjustable and detachable cosmetic box pushing structure, including a frame, a feeding device, and a pushing device. The feeding device is connected to the frame and is used to transport cosmetic boxes to the feeding channel on the frame; the pushing device is fixedly connected to the frame and is used to push the cosmetic boxes at the end of the feeding channel to the next station. The feeding device includes a conveyor and an auxiliary feeding device connected to the output end of the conveyor, the auxiliary feeding device being connected to the feeding channel of the frame; the pushing device includes a pushing plate, an adjusting component, and a buffer driving component, the buffer driving component being fixed below the frame and passing through the frame to connect with the pushing plate, the pushing plate being disposed above the frame and movable in a direction perpendicular to the feeding direction of the feeding channel, the adjusting component being disposed on one side of the pushing plate and fixed to the frame, and the buffer driving component driving the pushing plate to perform reciprocating linear motion.

[0010] Furthermore, the auxiliary feeding device includes a fixed base, a sliding base, an adjusting rack, a first auxiliary conveyor belt, a second auxiliary conveyor belt, and an auxiliary drive device. The fixed base and the sliding base are arranged opposite to each other. One end of the adjusting rack is fixedly connected to the fixed base, and the other end passes through the sliding base and meshes with it. The relative position between the sliding base and the fixed base can be adjusted by adjusting the rack. The first auxiliary conveyor belt is mounted on either the fixed base or the sliding base, and the second auxiliary conveyor belt is mounted on the opposite base. The two are arranged opposite each other and form a material passage, which is connected to the outlet of the conveyor. The auxiliary drive device is fixedly connected to the frame and is used to drive the first and second auxiliary conveyor belts to rotate synchronously.

[0011] Furthermore, the auxiliary feeding device also includes a pressure plate and a pressure bracket. The pressure bracket is located at the junction of the conveyor and the material passage, and the pressure plate is located above the conveyor and is adjustablely connected to the pressure bracket, allowing its position to be adjusted according to the height of the cosmetic box.

[0012] Furthermore, the adjusting component includes a guide plate, a fixed block, an adjusting block, and a handle. The fixed block is fixedly connected to the frame, one end of the adjusting block passes through the fixed block, and the other end is fixedly connected to the guide plate, allowing the adjusting block to reciprocate relative to the fixed block. The handle is fixed to the fixed block and used to lock the position of the adjusting block. The guide plate abuts against the pusher plate and is located at the end of the feeding channel.

[0013] Furthermore, the adjustment block is equipped with a scale so that the operator can intuitively read the adjustment amount.

[0014] Furthermore, the buffer drive component includes a connecting seat, a connecting block, a linear slider, a slide rod, a fixing plate, and a pushing cylinder. The fixing plate is fixed to the bottom of the frame and is respectively disposed at both ends of the slide rod. The linear slider passes through the slide rod and can slide along the slide rod. The connecting seat is fixedly connected to the linear slider, and the output end of the pushing cylinder is fixedly connected to the linear slider, thereby driving the linear slider to reciprocate along the slide rod. The connecting block is fixed to the connecting seat and passes through the frame to connect to the pusher plate.

[0015] Furthermore, the buffer drive component also includes an elastic pad and an elastic slider. The elastic pad is disposed on a fixed plate away from the push cylinder, and the elastic slider is fixedly connected to the end of the connecting seat near the push cylinder.

[0016] Furthermore, the buffer drive component also includes a lower locking block, an upper locking block, a limiting rod, and a limiting block. Each of the lower and upper locking blocks has a slot on one side. The lower locking block is fixedly connected to the connecting seat, and the two ends of the upper and lower locking blocks are detachably connected. The limiting rod is engaged in the slot. The limiting block is fixedly connected to the frame, and the limiting rod can abut against the limiting block.

[0017] Furthermore, the buffer drive component also includes a limiting side plate, which is fixed to both sides of the linear slider. The limiting side plate is provided with a limiting groove, through which the limiting rod passes.

[0018] Furthermore, the output end of the push cylinder is fixedly connected to the linear slider via an adjusting lower plate, and the adjusting lower plate and the linear slider are adjustable.

[0019] The beneficial effects of this utility model are:

[0020] 1. The feeding device of this utility model adopts a combination of conveyor and auxiliary feeding device, which can smoothly transport cosmetic boxes to the feeding channel of the frame; the pushing device drives the pushing plate to reciprocate through the buffer drive component, and adjusts the pushing position with the adjustment component, so as to realize the stable pushing of cosmetic boxes, accurate positioning, and improve production efficiency.

[0021] 2. The width of the material passage of the auxiliary feeding device in this invention can be adjusted by adjusting the toothed rod to accommodate cosmetic boxes of different sizes; the position of the guide plate of the positioning component can also be adjusted to meet the end positioning requirements of boxes of different specifications. Through the above-mentioned adjustable design, this structure can flexibly handle cosmetic boxes of various specifications, improving the versatility of the equipment.

[0022] 3. The buffer drive component of this utility model is equipped with buffer elements such as elastic column pads and elastic sliders, which absorb impact energy during the reciprocating motion of the pusher plate, reduce rigid collisions, thereby reducing equipment wear and noise, and extending service life. At the same time, the cooperation between the limit rod and the limit block can limit the maximum stroke of the pusher plate, avoiding damage to components caused by excessive retraction of the cylinder.

[0023] 4. The components of this utility model are mostly detachable (such as upper locking block and lower locking block, adjusting block and fixing block, etc.), which facilitates adjustment and maintenance. The overall structure is reasonably laid out, occupies little space, and is conducive to the compact layout of the production line. Attached Figure Description

Detailed Implementation

[0035] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0036] like Figure 1 As shown, the adjustable and detachable cosmetic box pushing structure provided by this utility model mainly includes a frame 1, a feeding device 2, and a pushing device 3. The frame 1 serves as a supporting base, and the feeding device 2 is installed at one end of the frame 1 to transport the cosmetic box to the feeding channel 4 on the frame 1; the pushing device 3 is installed on the frame 1 near the end of the feeding channel 4 to push the cosmetic box to the next work station.

[0037] Furthermore, the feeding device 2 includes a conveyor 21 and an auxiliary feeding device 22. The conveyor 21 can be a belt conveyor or a roller conveyor, etc., used to continuously transport cosmetic boxes from the upstream process to the auxiliary feeding device 22. The auxiliary feeding device 22 is connected to the output end of the conveyor 21 and communicates with the feeding channel 4 of the frame 1. Its function is to smoothly guide the cosmetic boxes delivered by the conveyor 21 into the feeding channel 4 and to provide necessary guidance and positioning for the boxes.

[0038] like Figure 2 , Figure 3As shown, the auxiliary feeding device 22 includes a fixed base 221, a sliding base 222, an adjusting rack 223, a first auxiliary conveyor belt 224, a second auxiliary conveyor belt 225, and an auxiliary drive device 226. The fixed base 221 and the sliding base 222 are a pair of oppositely arranged seats. The fixed base 221 is fixedly mounted on the frame 1, while the sliding base 222 can move relative to the fixed base 221 to adjust the distance between them. One end of the adjusting rack 223 (e.g., a screw or rack structure) is fixed to the fixed base 221, and the other end passes through the sliding base 222 and meshes with a threaded hole or gear on the sliding base 222. By rotating the adjusting rack 223, the sliding base 222 can be moved axially along the adjusting rack 223, thereby changing the distance between the fixed base 221 and the sliding base 222. The first auxiliary conveyor belt 224 and the second auxiliary conveyor belt 225 are respectively mounted on the fixed base 221 and the sliding base 222 (or one is mounted on the fixed base and the other on the sliding base), arranged opposite each other, forming a material passage for a single cosmetic box to pass through. The inlet of the material passage is connected to the outlet of the conveyor 21, and the outlet is connected to the feeding channel 4 of the frame 1. The auxiliary drive device 226 (e.g., a motor and transmission mechanism) is fixed to the frame 1, and its output power drives the first auxiliary conveyor belt 224 and the second auxiliary conveyor belt 225 to operate synchronously through transmission components (such as synchronous belts, sprockets, etc.). When the cosmetic box enters the material passage from the conveyor 21, the auxiliary conveyor belts on both sides simultaneously clamp the sides of the box and convey it forward, ensuring that the box remains upright and does not deviate when entering the feeding channel 4.

[0039] Furthermore, the auxiliary feeding device 22 also includes a pressure plate 227 and a pressure bracket 228. The pressure bracket 228 is installed horizontally above the junction of the conveyor 21 and the material passage. The pressure plate 227 is mounted on the pressure bracket 228 with bolts or other fasteners, and its position can be adjusted up and down along the bracket. A certain gap is left between the bottom surface of the pressure plate 227 and the surface of the conveyor 21. This gap is slightly larger than the thickness of the cosmetic box, so that a slight pressure is applied to the top of the box when it passes through, preventing the front end of the box from tilting up or getting stuck at the junction. By adjusting the height of the pressure plate 227, cosmetic boxes of different thicknesses can be accommodated, ensuring a smooth feeding process.

[0040] The feeding device 3 includes a feeding plate 31, an adjusting component 32, and a buffer drive component 33, such as Figure 4 As shown. The pusher plate 31 is a plate-shaped component, located above the end of the feeding channel 4 of the frame 1, with its plate surface facing the outlet direction of the feeding channel 4. The movement direction of the pusher plate 31 is perpendicular to the feeding direction of the feeding channel 4. That is, when the cosmetic box is conveyed to the position along the feeding channel 4, the pusher plate 31 will move laterally (e.g., from the side) to push the box out of the feeding channel and send it to the next station.

[0041] The adjusting component 32 is used to adjust the initial position and pushing stroke reference of the pusher plate 31. For example... Figure 7 As shown, the adjusting component 32 includes a guide plate 321, a fixing block 322, an adjusting block 323, and a handle 324. The fixing block 322 is fixedly mounted on the frame 1 and located on one side of the pusher plate 31. The adjusting block 323 is a screw or slide bar structure, with one end passing through a hole in the fixing block 322 and the other end fixedly connected to the guide plate 321. The adjusting block 323 can slide back and forth or rotate within the fixing block 322, thereby driving the guide plate 321 closer to or further away from the pusher plate 31. The handle 324 is mounted on the fixing block 322 and is used to lock the adjusting block 323 in the desired position (e.g., the handle can press the adjusting block to prevent it from moving). The guide plate 321 is typically a flat plate parallel to the pusher plate 31, located at the end of the feeding channel 4, and positioned opposite to the pusher plate 31. When the pusher plate 31 is in its retracted initial position, its side abuts against the guide plate 321, and the guide plate 321 provides a positioning reference for the pusher plate 31. By adjusting the position of the guide plate 321, the initial position of the pusher plate 31 can be changed, thereby adjusting the starting point of the push stroke to adapt to cosmetic boxes of different sizes or different push distance requirements. Preferably, the adjusting block 323 is marked with a scale 325 so that the operator can accurately adjust and read the distance the guide plate 321 has moved.

[0042] The buffer drive component 33 is the power source of the pushing device 3, used to drive the pushing plate 31 to perform reciprocating linear motion, and providing buffering and vibration reduction functions during the motion. Figure 5 , Figure 6 As shown, the buffer drive component 33 includes a connecting seat 331, a connecting block 332, a linear slider 333, a sliding rod 334, a fixing plate 335, and a push cylinder 336. Two fixing plates 335 are fixedly installed on both sides below the frame 1. The two ends of the sliding rod 334 are fixed to the two fixing plates 335 respectively, forming a linear guide rail spanning below the frame. The linear slider 333 is fitted onto the sliding rod 334 and can slide freely along the sliding rod 334. The connecting seat 331 is fixedly installed on the linear slider 333 and moves with the slider. The push cylinder 336 (e.g., a pneumatic cylinder or hydraulic cylinder) is fixedly installed below the frame 1, and the end of its piston rod is fixedly connected to the linear slider 333 or the connecting seat 331. When the cylinder 336 extends or retracts, it drives the linear slider 333 to slide back and forth along the sliding rod 334. The connecting block 332 is fixedly installed on the connecting seat 331 and passes upward through the long slot on the frame 1 to connect with the pusher plate 31, thereby transmitting the movement of the connecting seat 331 to the pusher plate 31. In this way, when the cylinder 336 drives the linear slider 333 to slide, the pusher plate 31 performs synchronous reciprocating linear motion above the frame 1, realizing the pushing and resetting of the cosmetic box.

[0043] To reduce the impact and vibration during the movement of the pusher plate 31, the buffer drive component 33 is also equipped with elastic buffer elements. Specifically, an elastic pad 337 (e.g., a polyurethane or rubber buffer pad) is installed on the fixed plate 335 on the side away from the push cylinder 336, and an elastic slider 338 (e.g., a rubber block) is fixed at the end of the connecting seat 331 near the push cylinder 336. When the linear slider 333 drives the connecting seat 331 to the end of its stroke, the elastic slider 338 will first collide with the fixed plate 335 near the cylinder. When the pusher plate 31 completes its push and returns, the other end of the connecting seat 331 will impact the elastic pad 337. These elastic elements deform upon impact, absorbing the impact energy, thereby buffering the impact force at the end of the cylinder's movement, reducing noise, and protecting the components from damage by hard impacts.

[0044] The buffer drive component 33 also includes a stroke limiting mechanism to limit the maximum stroke of the pusher plate 31 and prevent it from moving excessively. This mechanism includes a lower locking block 339, an upper locking block 3310, a limiting rod 3311, and a limiting block 3312. The lower locking block 339 is fixedly mounted on the connecting seat 331, and the upper locking block 3310 is detachably connected to the lower locking block 339 by bolts or the like. Both have semi-circular or rectangular slots on opposite sides. The limiting rod 3311 is a round rod that engages in the slots of the lower locking block 339 and the upper locking block 3310, thus being fixed to the connecting seat 331 and moving with it. The limiting block 3312 is fixedly mounted below the frame 1, located on one side of the movement path of the limiting rod 3311. When the connecting seat 331 moves the limiting rod 3311 to its limit position, the limiting rod 3311 abuts against the limiting block 3312, preventing the connecting seat 331 from moving further, thus limiting the maximum stroke of the pusher plate 31. The end position of the pusher plate 31's stroke can be changed by adjusting the position of the limiting rod 3311 in the slot (e.g., selecting a limiting rod of different length or changing its insertion depth). Furthermore, limiting side plates 3313 are fixed on both sides of the linear slider 333, with limiting grooves 3314 formed on the side plates 3313 through which the limiting rod 3311 passes. The limiting grooves 3314 provide lateral guidance and limit to the limiting rod 3311, preventing it from swaying during movement and ensuring accurate impact with the limiting block 3312, thus improving the reliability and safety of the limit.

[0045] To facilitate adjustment of the initial position and stroke of the pusher plate 31, the output end of the push cylinder 336 is connected to the linear slider 333 via an adjusting lower plate 3315. The adjusting lower plate 3315 can be a connecting plate with elongated holes, connected to the linear slider 333 by bolts, allowing for fine-tuning of their relative positions within a certain range. When fine adjustments to the initial extension or retraction position of the pusher plate 31 are needed, the bolts on the adjusting lower plate 3315 can be loosened, the position of the linear slider 333 relative to the cylinder piston rod can be moved, and then it can be tightened again.

[0046] In the cosmetic packaging production line, after the upstream process transports the cosmetic box to the conveyor 21, the conveyor 21 sends the box into the material passage of the auxiliary feeding device 22. The auxiliary conveyor belts 224 and 225 on both sides clamp the box and operate synchronously, smoothly transporting it to the feeding channel 4 of the frame 1. The pressure plate 227 applies slight pressure above the box to ensure that the box remains horizontal and does not tilt during the transport process. When the cosmetic box reaches the end of the feeding channel 4 and stops in place, the pushing device 3 starts to operate: it pushes the piston rod of the cylinder 336 to extend, driving the linear slider 333 to slide along the slide rod 334 towards the feeding channel 4. The connecting seat 331 and the connecting block 332 move accordingly, driving the pushing plate 31 to push out from the side. The pushing plate 31 contacts the cosmetic box and pushes it to the next station in a direction perpendicular to the feeding channel. After the pushing is completed, the piston rod of the cylinder 336 retracts, driving the pushing plate 31 to move in the opposite direction back to the initial position. During this process, the elastic slider 338 and the elastic pad 337 absorb the impact at both ends of the stroke, allowing the pusher plate 31 to stop smoothly. The limit rod 3311 moves under the drive of the connecting seat 331, and when it reaches the limit position, it abuts against the limit block 3312 to ensure that the pusher plate 31 does not move excessively.

[0047] When it is necessary to replace cosmetic boxes of different sizes, the operator can adjust the auxiliary feeding device 22 and the adjusting component 32 to adapt to the new size. Specifically, rotating the adjusting rack 223 adjusts the position of the sliding seat 222 so that the width of the material passage matches the width of the new box; at the same time, releasing the handle 324 moves the adjusting block 323 to change the position of the guide plate 321 so that the initial position of the pusher plate 31 is aligned with the side of the new box. After adjustment, locking the handle 324 to fix the adjusting block 323, and confirming the adjustment amount according to the scale 325. Through the above adjustments, the new cosmetic box can be accurately fed and pushed.

[0048] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
