Description

Technical Field

[0001] This utility model relates to the field of filling and sealing machine technology, specifically a filling and sealing machine with accurate positioning. Background Technology

[0002] The precise positioning filling and sealing machine is an automated device that integrates quantitative material filling, precise container positioning, and sealing. Its core advantage lies in solving the problems of "inaccurate filling, leakage, and material leakage caused by container offset" in traditional filling and sealing machines through precise structural design. It is widely used in the food, pharmaceutical, and daily chemical industries for packaging sauces, oral liquids, and skin care product samples.

[0003] In existing technologies, containers are prone to shifting, tipping, or stacking on the conveyor track due to vibration and inertia. Even if the container position is captured by visual positioning, it is impossible to fix the container with a limiting structure, which makes it impossible for the container to align with the filling port and the sealing mold. This makes it difficult to carry out the subsequent filling and sealing processes normally. Secondly, the container is prone to displacement during the filling process, causing material to spill outside the container or the injection volume to be uneven, which cannot guarantee the quantitative filling effect, and a large amount of material is wasted, significantly increasing production costs. Utility Model Content

[0004] The purpose of this invention is to provide a filling and sealing machine with accurate positioning, so as to solve the problem mentioned in the background art that containers are prone to deviation, tipping or stacking on the conveying track due to vibration and inertia. Even if the position of the container is captured by visual positioning, a large amount of material is wasted, which significantly increases the production cost.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precise positioning filling and sealing machine, comprising a production base, a rotating assembly mounted on the production base, a continuous turntable mounted on the rotating assembly, a guide assembly mounted on the production base, a filling device mounted on the production base, a clamping device mounted on the production base, a fixed base fixedly connected to the continuous turntable, a fixed support plate fixedly connected to the fixed base, an electric telescopic rod fixedly connected to the fixed base, a limiting fixing sleeve fixedly connected to the electric telescopic rod, a support mounting plate fixedly connected to the limiting fixing sleeve, and a fixed... The system includes a first fixed corner block connected to a support mounting plate, a first clamping bracket rotatably connected to the first fixed corner block, a clamping limiting band fixedly connected to the first clamping bracket, a second fixed corner block fixedly connected to the support mounting plate, a second clamping bracket rotatably connected to the second fixed corner block, an activation telescopic rod installed between the second clamping bracket and the first clamping bracket, an airtight suction device installed on the support mounting plate, and a heating sealing device installed on the limiting fixing sleeve. One of the clamping limiting bands is installed on the second clamping bracket, and the activation telescopic rod drives the second clamping bracket and the first clamping bracket to move closer to each other or further away from each other.

[0006] In the preferred embodiment of this technical solution, two first fixed corner blocks and two second fixed corner blocks are provided, and the two first fixed corner blocks and the two second fixed corner blocks are symmetrically installed on the support mounting plate.

[0007] Based on the preferred embodiment of this technical solution, the clamping and limiting band has a slot at the corresponding position of the discharge pipe of the filling device, and the discharge pipe is clamped inside the slot.

[0008] In the preferred embodiment of this technical solution, there are several fixed bases, and these fixed bases are arranged in a row on the continuous turntable.

[0009] According to the preferred embodiment of this technical solution, the guide component includes a support base fixedly connected to the production base and a rotating guide wheel rotatably connected inside the support base, with the rotating guide wheel in contact with the bottom of the continuous turntable.

[0010] Based on the preferred embodiment of this technical solution, several support bases are provided, and the several support bases are evenly and fixedly connected to the production base.

[0011] In a preferred embodiment of this technical solution, the rotating assembly includes a drive motor fixedly connected to the production base, a first rotating pulley fixedly connected to the output end of the drive motor, a second rotating pulley rotatably connected to the production base, a transmission belt body transmitting power between the first and second rotating pulleys, a rotating worm fixedly connected to the second rotating pulley, a rotating connecting shaft rotatably connected inside the production base, and a rotating worm wheel fixedly connected to the rotating connecting shaft. The rotating worm wheel meshes with a rotating support disc fixedly connected to the rotating worm and the rotating connecting shaft. The drive motor drives the rotating connecting shaft to rotate the rotating support disc clockwise.

[0012] In a preferred embodiment of this technical solution, the first and second rotating pulleys have toothed grooves at corresponding positions on the transmission belt body, and the teeth on the transmission belt body mesh with each other within the toothed grooves. Compared with the prior art, the beneficial effects of this utility model are: 1. The telescopic rod drives the first and second clamping brackets to approach each other, working in conjunction with the clamping limit straps to firmly secure the container. The two clamping brackets are symmetrically installed to prevent container shifting and tipping. The clamping limit straps engage with the discharge pipe of the filling device, ensuring precise alignment between the container opening and the discharge pipe, preventing material spillage during filling, reducing waste and costs. Simultaneously, multiple support bases of the guide assembly are evenly distributed, and rotating guide wheels adhere to the bottom of the continuous turntable, assisting in smooth turntable rotation and preventing container displacement due to vibration. Several fixed bases on the continuous turntable are arranged in rows, enabling continuous multi-station production and improving efficiency. The overall structure, through the synergy of mechanical limiting and stable transfer, completely solves the problems of difficult container alignment and uneven filling, significantly optimizing production results.

[0013] 2. Several evenly distributed support bases on the production base provide a stable mounting foundation for the rotating guide wheels. This provides balanced support to the bottom of the continuous turntable from multiple points, preventing the turntable from sinking or tilting due to uneven local stress, ensuring the overall levelness of the turntable, and laying the foundation for stable container transport. Simultaneously, the contact between the rotating guide wheels and the bottom of the continuous turntable converts the sliding friction during turntable rotation into rolling friction, significantly reducing frictional resistance. This not only reduces wear on the turntable and guide components, extending their service life, but also reduces the driving load on the rotating components, allowing for smoother turntable rotation. Furthermore, the rotating guide wheels can correct the turntable's rotation trajectory in real time, preventing the turntable from deviating from the preset path due to inertia or vibration. This ensures that the fixed bases on the turntable are precisely aligned with each station, indirectly guaranteeing the alignment accuracy of the container with the filling and sealing molds, further improving production stability.

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.

[0017] Please see Figure 1-5 This utility model provides an embodiment of a filling and sealing machine for accurate positioning: It includes a production base 1, a rotating assembly mounted on the production base 1, a continuous turntable 2 mounted on the rotating assembly, a guide assembly mounted on the production base 1, a filling device 3 mounted on the production base 1, a clamping device 4 mounted on the production base 1, a fixed base 901 fixedly connected to the continuous turntable 2, a fixed support plate 902 fixedly connected to the fixed base 901, an electric telescopic rod 903 fixedly connected to the fixed base 901, a limiting fixing sleeve 904 fixedly connected to the electric telescopic rod 903, a support mounting plate 905 fixedly connected to the limiting fixing sleeve 904, a first fixing corner block 906 fixedly connected to the support mounting plate 905, a first clamping bracket 907 rotatably connected to the first fixing corner block 906, a clamping limiting band 908 fixedly connected to the first clamping bracket 907, and a fixed support plate 902 fixedly connected to the support plate 905. The mounting plate 905 includes a second fixed corner block 909, a second clamping bracket 910 rotatably connected to the second fixed corner block 909, an activation telescopic rod 911 installed between the second clamping bracket 910 and the first clamping bracket 907, an airtight suction device 912 installed on the support mounting plate 905, and a heating sealing device 913 installed on the limiting fixing sleeve 904. One of the clamping limiting bands 908 is installed on the second clamping bracket 910. The activation telescopic rod 911 drives the second clamping bracket 910 and the first clamping bracket 907 to move closer or further apart. Through the rotating component, the continuous turntable 2 is driven to rotate stably, which can realize the automatic transfer of containers between different workstations. With the guide component, the stability of the continuous turntable 2 during rotation is further ensured, and the turntable offset is avoided from affecting the positioning accuracy of the container. The electric telescopic rod 903 can drive the limiting fixing sleeve 904 to adjust up and down to adapt to containers of different heights and enhance the compatibility of the equipment with containers of multiple specifications.

[0018] Please see Figure 2-3A further solution based on this embodiment is as follows: two first fixed corner blocks 906 and two second fixed corner blocks 909 are respectively provided, and the two first fixed corner blocks 906 and two second fixed corner blocks 909 are symmetrically installed on the support mounting plate 905. By symmetrically installing the two first fixed corner blocks 906 and two second fixed corner blocks 909 on the support mounting plate 905, symmetrical support points can be provided for the first clamping bracket 907 and the second clamping bracket 910 respectively, so that the clamping bracket is subjected to uniform force during rotation, and avoids deformation or displacement of the bracket due to uneven force on one side.

[0019] Please see Figure 2-3 A further solution based on this embodiment is as follows: the clamping and limiting band 908 has a slot at the corresponding position of the discharge pipe of the filling device 3, and the discharge pipe is clamped inside the slot. By opening a slot on the clamping and limiting band 908 at the corresponding position of the discharge pipe of the filling device 3 and clamping the discharge pipe inside the slot, the discharge pipe and the container opening can be accurately aligned, avoiding material spillage due to the displacement of the discharge pipe.

[0020] Please see Figure 2-3 A further solution based on this embodiment is as follows: a number of fixed bases 901 are provided, and the number of fixed bases 901 are arranged in a row on the continuous turntable 2. By arranging a number of fixed bases 901 in a row on the continuous turntable 2, the equipment can process multiple containers at the same time, realize multi-station synchronous operation, and greatly improve production efficiency; the arrangement of fixed bases 901 in a row can ensure that the spacing of each station is uniform.

[0021] Please see Figure 5 A further solution based on this embodiment is as follows: the guide assembly includes a support base 808 fixedly connected to the production base 1 and a rotating guide wheel 809 rotatably connected inside the support base 808. The rotating guide wheel 809 is in contact with the bottom of the continuous turntable 2. The support base 808 provides a stable mounting base for the rotating guide wheel 809, ensuring that the rotating guide wheel 809 can continuously contact the bottom of the continuous turntable 2. The rotating guide wheel 809 can convert the sliding friction of the continuous turntable 2 into rolling friction, greatly reducing the friction force when the turntable rotates, reducing the load on the rotating assembly, and extending the service life of components such as the drive motor 801.

[0022] Please see Figure 5 A further solution based on this embodiment is as follows: several support bases 808 are provided, and the several support bases 808 are evenly fixedly connected to the production base 1. By evenly fixing several support bases 808 on the production base 1, the rotating guide wheels 809 on each support base 808 can evenly distribute the weight of the continuous turntable 2, avoiding deformation of the turntable or damage to the guide wheels due to excessive local stress; the evenly distributed support bases 808 can support and guide the continuous turntable 2 from multiple points.

[0023] Please see Figure 4-5 A further embodiment of this solution is as follows: the rotating assembly includes a drive motor 801 fixedly connected to the production base 1, a first rotating pulley 802 fixedly connected to the output end of the drive motor 801, a second rotating pulley 803 rotatably connected to the production base 1, a transmission belt body 804 drivingly connected between the first rotating pulley 802 and the second rotating pulley 803, a rotating worm gear 805 fixedly connected to the second rotating pulley 803, a rotating connecting shaft 806 rotatably connected inside the production base 1, and a rotating worm wheel 807 fixedly connected to the rotating connecting shaft 806, the rotating worm wheel 807 meshing with the rotating worm gear 802. The rotating support disk 810 is fixedly connected to the rotating connecting shaft 806. The drive motor 801 drives the rotating connecting shaft 806 to rotate the rotating support disk 810 in a clockwise direction. The drive motor 801 provides stable power, which is transmitted smoothly to the rotating worm 805 through the first rotating pulley 802, the transmission belt body 804, and the second rotating pulley 803. The meshing transmission between the rotating worm 805 and the rotating worm wheel 807 has the effect of speed reduction and torque increase, which can reduce the speed of the rotating connecting shaft 806 and increase the torque, ensuring that the rotating support disk 810 drives the continuous turntable 2 to rotate smoothly and avoid the container shifting due to excessive speed.

[0024] Please see Figure 4-5 A further solution based on this embodiment is as follows: the first rotating pulley 802 and the second rotating pulley 803 have tooth grooves at the corresponding positions of the teeth on the transmission belt body 804. The teeth on the transmission belt body 804 are engaged with the inside of the tooth grooves. By opening tooth grooves at the corresponding positions of the first rotating pulley 802, the second rotating pulley 803 and the transmission belt body 804, and adopting a tooth meshing connection, slippage of the transmission belt body 804 during transmission can be avoided, ensuring that power can be efficiently and stably transmitted from the drive motor 801 to the subsequent components, and reducing power loss.

[0025] Working principle: The container is placed on the fixed base 901 of the continuous turntable 2 by the feeding mechanism. The telescopic rod 911 drives the first clamping bracket 907 and the second clamping bracket 910 to move closer to each other. The container is firmly fixed by the clamping limit band 908, and the slot of the clamping limit band 908 engages with the discharge pipe of the filling device 3 to ensure precise alignment between the container opening and the discharge pipe. Subsequently, the rotating component is started: the drive motor 801 drives the first rotating pulley 802 to rotate, which is transmitted to the second rotating pulley 803 through the transmission belt body 804. This, in turn, drives the rotating worm gear 805 to mesh with the rotating worm wheel 807, so that the rotating connecting shaft 806 drives the rotating support plate 810 and the continuous turntable 2 to rotate smoothly clockwise. During the rotation process, the rotating guide wheel 809 of the guide assembly rolls against the bottom of the continuous turntable 2, assisting the turntable in stable transportation and ensuring that the container is accurately delivered to the filling device 3 station. After reaching the filling station, the filling device 3 injects material into the container through the discharge pipe. The electric telescopic rod 903 can finely adjust the position of the limit fixing sleeve 904 according to the height of the container to ensure smooth filling. After filling, the turntable continues to transport to the sealing station. The airtight suction device 912 first removes excess air from the container, and then the heating sealing device 913 seals the container. Finally, the turntable transports the sealed finished product to the unloading station, the clamping bracket is released, and one production cycle is completed, realizing continuous automated precision production.

[0026] 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.
