Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, specifically to a positioning device for packaging products that is easy to operate. Background Technology

[0002] With the rapid development of the industrial economy, the product packaging industry has played an increasingly prominent role in promoting national economic development and improving people's quality of life. In the production and processing of plastic packaging products, such as plastic boxes and plastic bottles, it is often necessary to move these products. Therefore, a special positioning structure for packaging products is needed to fix the packaging products on the moving device.

[0003] According to the patent application published on the Internet (authorization announcement number: CN220315057U), "This utility model relates to the field of positioning technology for packaging products, and discloses a positioning structure for packaging products, including a main body, a moving mechanism at the bottom of the main body, a rolling mechanism at the front of the main body, a pusher mechanism at the rear wall of the main body, and a positioning mechanism at the top of the main body. The main body includes a roller groove, which is opened at the central axis of the top of the main body, and connecting rods are fixedly connected to the inner walls on both sides of the roller groove. After the packaging product enters above the main body, the positioning frame and positioning plate of the positioning mechanism are installed in the roller groove through a slide. By adjusting the position of the slide, the positioning plate contacts the packaging product. Then, the fixing plate is connected to the fixing hole by a pin to position the positioning plate, preventing the packaging product placed on the moving device from falling, thereby increasing the efficiency of handling the packaging product. The ramp can be disassembled through the mounting frame and the limiting plate to facilitate the removal of the rolling mechanism."

[0004] Based on the above, the applicant believes the following issues exist:

[0005] In existing technology, when adapting to packaging products of different sizes, the current equipment uses an adjustable positioning mechanism for fixing. Specifically, the positioning mechanism is first moved to a position that matches the size of the packaging product by an adjustment device. After accurate positioning, a pin is inserted to lock the mechanism. Each adjustment requires the pin to be completely removed before positioning can be adjusted, and after adjustment, it must be reinserted to fix it. This separate operation mode causes the entire adjustment process to require repeated disassembly and reassembly of the pin, which not only increases the operation steps and time costs, but also easily causes pin wear or positioning deviation during frequent insertion and removal, ultimately resulting in low efficiency and affecting positioning accuracy. Utility Model Content

[0006] The purpose of this invention is to provide a positioning device for packaging products that is easy to operate, so as to solve the problem mentioned in the background art that the adjustment positioning mechanism requires frequent disassembly and assembly of pins, which is cumbersome to operate.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for packaging products that is easy to operate, including a base plate, casters mounted on the bottom of the base plate, and a handle fixedly connected to the top of the base plate. It also includes a slider slidably connected to the base plate, a slide plate slidably connected inside the slider, a pull ring fixedly connected to one end of the slide plate, a push block fixedly connected to the other end of the slide plate, a locking block slidably connected to the slider, a spring fixedly connected between the locking block and the slider, a positioning component for positioning the packaging products mounted on the top of the slider, and a conveying component mounted on the base plate. The push block and the locking block slide on the slider. When the push block slides, it drives the locking block to slide synchronously, thereby driving the locking block to disengage from the base plate.

[0008] In the preferred embodiment of this technical solution, the card block has matching grooves at the corresponding positions of the pushing block and the sliding plate, and the pushing block and the sliding plate slide inside the corresponding grooves respectively.

[0009] Based on the preferred embodiment of this technical solution, the base plate has several slots at the corresponding positions driven by the card block, and the card block is engaged inside the slots.

[0010] According to the preferred embodiment of this technical solution, the positioning component includes a vertical rod fixedly connected to the top of the slider, a first threaded rod rotatably connected to the vertical rod, an extension rod threadedly connected to the first threaded rod, a bent rod fixedly connected to the top of the extension rod, a positioning plate slidably connected to the bent rod, and a rubber ring fixedly connected between the positioning plate and the bent rod, with the extension rod slidably connected to the vertical rod.

[0011] In the preferred embodiment of this technical solution, the bent rod has a limiting hole at the corresponding position of the positioning plate, and the rubber ring is compressed when the positioning plate slides inside the limiting hole.

[0012] According to the preferred embodiment of this technical solution, the conveying assembly includes a conveying roller rotatably connected to the base plate, a sprocket fixedly connected to the conveying roller, a chain meshing with the sprocket, a nut rotatably connected to the base plate, a second threaded rod threadedly connected to the nut, a limiting plate fixedly connected to one end of the second threaded rod, and a hexagonal clamping plate fixedly connected to the side of the limiting plate away from the second threaded rod. When the limiting plate slides on the base plate, it drives the hexagonal clamping plate away from or in contact with the conveying roller.

[0013] In the preferred embodiment of this technical solution, the conveying roller is provided with a slot that matches the hexagonal card plate, and the hexagonal card plate is engaged inside the slot.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. Pulling the pull ring releases the slider, allowing for flexible adjustment. The slider, previously fixed, gains free movement, enabling it to move flexibly within a predetermined track or range. Operators can then precisely adjust the slider's position according to the actual dimensions of the packaged product, thereby moving the positioning component to the appropriate location and completing the adjustment to meet diverse packaging needs.

[0016] 2. The vibration of the conveyor rollers can reduce the friction of the packaging products sliding on the bottom plate, allowing the packaging products to slide and be loaded and unloaded, making it more convenient and labor-saving to use. In addition, the conveyor rollers can be fixed and cannot rotate, stably positioning the packaging products, so as not to affect the transportation of the packaging products.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 8 This utility model provides an embodiment of a positioning device for easy-to-operate packaging products, including a base plate 1, casters 6 mounted on the bottom of the base plate 1, and a handle 5 fixedly connected to the top of the base plate 1. It also includes a slider 21 slidably connected to the base plate 1, a slide plate 22 slidably connected inside the slider 21, a pull ring 23 fixedly connected to one end of the slide plate 22, a push block 24 fixedly connected to the other end of the slide plate 22, a locking block 25 slidably connected to the slider 21, and a spring 26 fixedly connected between the locking block 25 and the slider 21. A positioning component for the packaged product and a conveying component mounted on the base plate 1 are positioned at the top of the slider 21. A push block 24 and a locking block 25 slide on the slider 21. When the push block 24 slides, it drives the locking block 25 to slide synchronously, thereby causing the locking block 25 to disengage from the base plate 1. The base plate 1 serves as the supporting foundation of the device. Its bottom casters 6 facilitate overall device movement, and its top handle 5 allows operators to push or pull the device. The sliding of the slider 21 along the base plate 1 drives the positioning component to move synchronously, adapting to the positioning requirements of packaged products in different positions. When the operator pulls the slide plate 22 via the pull ring 23, the slide plate 22 drives the push block 24 to slide. The cooperation between the push block 24 and the locking block 25 causes the locking block 25 to overcome the elastic force of the spring 26 and slide, thus disengaging from the base plate 1 and unlocking the slider 21. This facilitates adjustment of the slider 21's position. After releasing the pull ring 23, the spring 26 resets, pushing the locking block 25 back into contact with the base plate 1, locking the slider 21. This eliminates the need for frequent insertion and removal of pins, simplifying the operation and improving positioning adjustment efficiency.

[0028] Please see Figure 3 - Figure 4 A further solution based on this embodiment is as follows: the locking block 25 has matching slots at the corresponding positions of the pushing block 24 and the sliding plate 22, and the pushing block 24 and the sliding plate 22 slide in the corresponding slots respectively. The slot of the sliding plate 22 corresponding to the locking block 25 is to avoid the path of the sliding plate 22 from conflicting with the locking block 25. The slot corresponding to the pushing block 24 is so that when the pushing block 24 slides, the locking block 25 can be pushed up, thereby compressing the spring 26, and the rise can be separated from the base plate 1, thereby releasing the restriction on the base plate 1 and allowing the base plate 1 to be adjusted in position.

[0029] Please see Figure 2A further solution based on this embodiment is as follows: The base plate 1 has several slots at corresponding positions driven by the locking block 25, and the locking block 25 engages within these slots. These slots on the base plate 1 are spaced apart along the sliding direction of the slider 21, providing multiple locking positions for the locking block 25. When the locking block 25 engages in different slots, the slider 21 can be fixed at different positions on the base plate 1, thereby achieving the fixing of the positioning component at different positions to adapt to the positioning requirements of packaging products of different sizes. The engagement of the locking block 25 with the slots provides a stable locking force, preventing accidental sliding of the slider 21 during device operation or movement, and ensuring positioning accuracy.

[0030] Please see Figure 1 - Figure 2 , Figure 5 - Figure 6 A further solution based on this embodiment is as follows: the positioning assembly includes a vertical rod 31 fixedly connected to the top of the slider 21, a first threaded rod 32 rotatably connected to the vertical rod 31, an extension rod 33 threadedly connected to the first threaded rod 32, a bent rod 34 fixedly connected to the top of the extension rod 33, a positioning plate 35 slidably connected to the bent rod 34, and a rubber ring 36 fixedly connected between the positioning plate 35 and the bent rod 34. The extension rod 33 is slidably connected to the vertical rod 31. The positioning plate 35 can adjust its horizontal position by sliding along the bent rod 34 so that it can contact the packaged product to achieve positioning. The rubber ring 36 can generate elastic deformation when the positioning plate 35 contacts the packaged product, which not only ensures the tightness of positioning but also avoids the positioning plate 35 causing hard compression damage to the packaged product.

[0031] Please see Figure 6 A further solution based on this embodiment is as follows: A limiting hole is formed in the corresponding position of the positioning plate 35 on the bent rod 34. When the positioning plate 35 slides inside the limiting hole, it compresses the rubber ring 36. The limiting hole on the bent rod 34 guides and limits the sliding of the positioning plate 35, preventing the positioning plate 35 from deviating from the preset direction or falling off the bent rod 34 during the sliding process, thus ensuring the stability of the positioning plate 35's movement. When the positioning plate 35 slides within the limiting hole and comes into contact with the packaged product, the reaction force of the packaged product on the positioning plate 35 causes the positioning plate 35 to compress the rubber ring 36. The elastic restoring force of the rubber ring 36 pushes the positioning plate 35 tightly against the packaged product, achieving elastic positioning. This can adapt to slight differences in the size of the packaged product while buffering external impact forces to prevent damage to the packaged product.

[0032] Please see Figure 1 , Figure 7 - Figure 8A further embodiment of this solution is as follows: the conveying assembly includes a conveying roller 41 rotatably connected to the base plate 1, a sprocket 42 fixedly connected to the conveying roller 41, a chain 43 meshing with the sprocket 42, a nut 44 rotatably connected to the base plate 1, a second threaded rod 45 threadedly connected to the nut 44, a limiting plate 46 fixedly connected to one end of the second threaded rod 45, and a hexagonal clamping plate 47 fixedly connected to the side of the limiting plate 46 away from the second threaded rod 45. When the limiting plate 46 slides on the base plate 1, it drives the hexagonal clamping plate 47 away from or in contact with the conveying roller 41. The conveying roller 41 is used to carry and convey packaged products. The sprocket 42 and the chain 43... The meshing transmission enables multiple conveyor rollers 41 to rotate synchronously, ensuring the smooth conveying of packaged products. When the nut 44 is turned, since the second threaded rod 45 is fixedly connected to the limiting plate 46 and the limiting plate 46 is restricted from rotating by the base plate 1, the second threaded rod 45 can drive the limiting plate 46 to slide along the base plate 1, thereby driving the hexagonal clamping plate 47 to approach or move away from the conveyor roller 41. When the hexagonal clamping plate 47 contacts the conveyor roller 41, it can brake the conveyor roller 41 and stop its rotation. When the hexagonal clamping plate 47 moves away from the conveyor roller 41, the conveyor roller 41 can rotate freely, restoring the conveying of packaged products, which is convenient for controlling the conveying state according to positioning requirements.

[0033] Please see Figure 8 A further solution based on this embodiment is as follows: A slot adapted to a hexagonal clamping plate 47 is provided on the conveyor roller 41, and the hexagonal clamping plate 47 is engaged inside the slot. The matching structure between the slot on the conveyor roller 41 and the hexagonal clamping plate 47 utilizes the non-circular characteristics of the hexagonal shape. After the hexagonal clamping plate 47 is engaged in the slot, the rotation of the conveyor roller 41 can be restricted, achieving reliable braking and preventing the conveyor roller 41 from accidentally rotating due to external force, thus avoiding displacement of the packaged product. Simultaneously, the precise fit between the slot and the hexagonal clamping plate 47 ensures the stability of the engagement and prevents slippage during braking. When it is necessary to release the brake, the hexagonal clamping plate 47 can smoothly disengage from the slot, allowing the conveyor roller 41 to quickly resume rotation. The operation is convenient and the braking effect is reliable.

[0034] Working principle: By holding handle 5, the base plate 1 can be moved via handle 5. Handle 5 has a self-locking function to position the base plate 1. To adjust slider 21 towards the center of the base plate 1, simply push slider 21. The locking block 25 has an inclined surface. Pushing slider 21 will cause it to press against the inclined surface through the slot of the base plate 1, thus automatically retracting the locking block 25 into the slider 21. To adjust the position of slider 21 to the other side, pull ring 23. Pull ring 23 drives slide plate 22, which in turn drives push block 24. Push block 24 presses against and pushes locking block 25. Locking block 25 compresses spring 26, causing locking block 25 to disengage from the slot, thus freeing slider 21 and allowing its position to be adjusted. Spring 26... The locking block 25 can be automatically reset and adjusted to a suitable position. Loosening the pull ring 23 will extend the spring 26, allowing the locking block 25 to re-engage into the corresponding slot. Twisting the first threaded rod 32 will rotate and drive the extension rod 33 to rise and fall, adjusting the height of the positioning plate 35. The positioning plate 35 will hold the packaged product in place. When loading or unloading the packaged product, the rotatable conveyor roller 41 will reduce friction, allowing the packaged product to slide on the base plate 1. Twisting the nut 44 will drive the second threaded rod 45 to slide the limiting plate 46. The limiting plate 46 will drive the hexagonal locking plate 47 to engage in the slot of the conveyor roller 41, thus braking the conveyor roller 41 and preventing it from rotating. This will position the packaged product at the top of the base plate 1.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
