Description

Technical Field

[0001] This utility model relates to the technical field of tablet forming devices, specifically a toothpaste tablet forming device. Background Technology

[0002] Toothpaste, an indispensable oral hygiene product in daily life, comes in various forms. Among them, sheet toothpaste is increasingly favored by consumers due to its portability and precise dosage. To adapt to the large-scale industrial production of sheet toothpaste, various toothpaste compression molding devices have emerged on the market.

[0003] Currently, a common toothpaste tablet forming device includes a fixed operating table, with one or more fixed molds and a tablet pressing mechanism mounted on top of the operating table. The working process typically involves: an operator or automatic feeding system injecting the toothpaste paste into the mold cavity; subsequently, the pressing head of the tablet pressing mechanism moves downwards under the drive of a drive unit, applying significant pressure to the toothpaste within the mold cavity, causing it to solidify into a tablet shape; after tablet pressing is complete, the entire device needs to be paused, and the operator manually or using a simple robotic arm removes the formed toothpaste tablet from the mold and cleans the mold for future use.

[0004] While this traditional toothpaste tablet compression device can achieve the basic tablet compression function, it has gradually revealed some shortcomings that urgently need improvement during actual production:

[0005] 1. Low production efficiency and inability to achieve continuous operation. After completing one tableting cycle, the existing equipment must interrupt the entire workflow, waiting for manual removal of the finished product and replacement of new raw materials. This "stop-remove-start" operation mode severely restricts the production cycle, resulting in a low percentage of effective working time for the equipment and limited output per unit time, making it difficult to meet the demands of modern large-scale, high-efficiency production.

[0006] 2. Inconvenient mold replacement and maintenance, resulting in poor flexibility. Most existing molds are directly fixed to the workbench or connected via simple clips. When switching production to produce toothpaste tablets of different shapes or sizes, operators must spend considerable time and effort disassembling and installing the molds. This cumbersome changeover process not only increases the labor intensity of workers and reduces the efficiency of production line changeovers, but also indirectly affects production flexibility and the company's market responsiveness.

[0007] Therefore, in view of this, the existing structure was studied and improved, and a toothpaste tablet forming device was proposed. Summary of the Invention

[0008] The technical problem this invention aims to solve is low production efficiency, inability to achieve continuous operation, inconvenience in mold replacement and maintenance, and poor flexibility.

[0009] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a toothpaste tablet forming device, including an operating table, a plurality of legs fixedly installed at the bottom of the operating table, a mold and a tablet forming assembly installed at the top of the operating table, a placement frame rotatably installed at the top of the operating table, a plurality of molds being provided and threadedly connected to the placement frame, and a rotating assembly for controlling the intermittent rotation of the placement frame being installed at the bottom of the operating table, the rotating assembly being able to intermittently control the rotation of the placement frame and simultaneously brake the position of the placement frame.

[0010] As a further embodiment of this utility model: the tablet pressing assembly includes a support frame fixedly installed on the top of the operating table, a telescopic rod fixedly installed at the top of the support frame, a sliding plate fixedly sleeved on the movable end of the telescopic rod, and the sliding plate is limited and slidably installed on the support frame, and a mold is threadedly connected to the movable end of the telescopic rod.

[0011] As a further embodiment of this utility model: the rotating assembly includes a receiving frame fixedly installed at the bottom of the operating table, a rotating block rotatably installed on the top of the receiving frame, an arc-shaped limiting block and a toggle member fixedly installed at the top of the rotating block, a driving member rotatably installed on the top of the receiving frame via a rotating shaft, and the driving member drives the placement frame to rotate, and a motor for driving the rotating block to rotate is fixedly installed at the bottom of the receiving frame.

[0012] As a further embodiment of this utility model: the driving component is provided with a plurality of arc-shaped grooves and a plurality of actuating grooves; when the arc-shaped limiting block rotates into the arc-shaped groove, it can brake the driving component, thereby braking the placement frame; when the actuating component rotates into the actuating groove, it can actuate the driving component to rotate, thereby driving the placement frame to rotate, and the arc-shaped limiting block and the actuating component intermittently contact the driving component, thereby enabling the intermittent rotation of the driving component.

[0013] As a further embodiment of this utility model: the placement rack is provided with a plurality of threaded grooves for threaded connection of the mold, and the number of threaded grooves is consistent with the number of arc grooves and actuation grooves.

[0014] As a further embodiment of this utility model: a heater is provided inside the placement rack and around the threaded groove.

[0015] As a further embodiment of this utility model, a rubber pad is fixedly provided at the bottom end of the foot rod.

[0016] Compared with the prior art, the advantages of this utility model are as follows:

[0017] 1. This utility model creatively integrates multiple molds arranged in a ring on a single, automatically rotating placement rack by setting a rotatable placement rack and a rotating component at the bottom of the operating table to control its intermittent rotation. During operation, driven by the rotating component, the placement rack sequentially rotates empty molds containing raw materials to the tableting station. After tableting, it automatically rotates to the next empty station, simultaneously removing the formed toothpaste tablets from the tableting area. This series of actions is continuous and automatic, eliminating the need to stop the machine to retrieve materials as required by traditional devices. Operators can easily retrieve finished products from molds outside the tableting station while the equipment is running continuously, truly achieving a parallel operation mode of "tableting and material retrieval simultaneously." This maximizes the effective utilization of the equipment, significantly increases output per unit time, and meets the demands of modern large-scale, high-efficiency production.

[0018] The core of the rotating assembly lies in the intermittent engagement between the arc-shaped limiting block and the actuating component on the rotating block, driven by a motor, and the arc-shaped groove and actuating groove on the driving component. When the arc-shaped limiting block engages with the arc-shaped groove of the driving component, it provides precise and rigid braking to the driving component and even the entire placement rack, ensuring that no slight displacement or wobbling occurs during tablet compression. This highly stable positioning is crucial for ensuring uniform tablet compression pressure, consistent density of the formed toothpaste tablets, and regular shape. Simultaneously, the engagement of the actuating component and the actuating groove reliably drives the placement rack to rotate stepwise. This design integrates driving and braking functions, resulting in a simple and reliable structure that effectively avoids defective products caused by positional deviations, thereby improving the product yield.

[0019] 2. This utility model designs multiple molds, one of which is detachably fixed in the threaded groove of the placement frame via a threaded connection, and another mold is threadedly connected to the movable end of the telescopic rod. When it is necessary to change toothpaste sheet molds of different specifications (such as shape and size), the operator only needs to loosen and remove the old mold and then tighten the new mold. The whole process is simple and quick, without the need for any special tools. This modular design completely eliminates the cumbersome fixing and disassembly methods in traditional devices, greatly facilitating mold maintenance and replacement, significantly reducing the labor intensity of workers, shortening production line changeover time, and enabling a production line to quickly respond to diverse market demands and produce different types of sheet toothpaste products.

Detailed Implementation

[0029] 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.

[0030] Please see Figure 1-6This utility model provides a toothpaste tablet forming device. Its main structure includes a stable operating platform 1. Four legs 2 are fixedly installed at the bottom of the operating platform 1 to support and stabilize the machine. The top of the operating platform 1 houses a mold 3 for carrying raw materials and a tableting assembly 4 for performing the tableting action. The core innovation of this utility model lies in the fact that instead of a fixed mold, a circular placement frame 5 is rotatably mounted on the top of the operating platform 1 via a rotary bearing. The placement frame 5 has several threaded holes (slots) at equal angles along its circumference. Several molds 3 are screwed into these slots one-to-one via threaded connections. To achieve automated intermittent rotation and precise positioning of the placement frame 5, a complete rotating assembly 6 is fixedly installed at the bottom of the operating platform 1. This rotating assembly 6 not only intermittently drives the placement frame 5 to rotate a fixed angle according to a preset program, but more importantly, it also has a strong braking capability, firmly locking the position of the placement frame 5 during the critical tableting process, ensuring no displacement and thus guaranteeing tableting accuracy.

[0031] Furthermore, as a preferred embodiment of this utility model, the structure of the tablet compression assembly 4 is as follows: Figure 1 , Figure 4 As shown, it includes an inverted U-shaped support frame 401, which is securely welded or bolted to the center of the top surface of the operating table 1 via a mounting plate at its bottom. A telescopic rod 402, driven by a hydraulic system or a high-power cylinder, is fixedly installed at the top inner part of the support frame 401. The extension and retraction of the telescopic rod 402 constitutes the main power source for tablet pressing. The movable end of the telescopic rod 402 extends vertically downwards, and a rectangular sliding plate 403 is fixedly fitted at its end. The four sides of the sliding plate 403 are confined within pre-set guide rail grooves on the inner wall of the support frame 401, allowing it to slide smoothly and without wobbling in the vertical direction, providing stable guidance for the tablet pressing process. A standard external thread is machined on the movable end of the telescopic rod 402, and a mold 404, matching mold 3, is screwed onto the movable end through its internal threaded hole. This design allows mold 404 to be easily and quickly replaced, like tightening a screw, to adapt to the production needs of toothpaste tablets of different shapes and thicknesses.

[0032] Furthermore, as the core mechanism for realizing the intermittent rotation function, the specific structure of the rotating component 6 is as follows: Figure 2 and Figure 3As shown, it includes a receiving frame 601 fixedly mounted on the bottom of the operating table 1 and isolated from the internal space of the operating table 1 to protect the internal precision components and prevent dust. On the top platform of the receiving frame 601, a rotating block 602 is rotatably mounted via a set of high-precision bearings. This rotating block 602 is the active drive source for the entire rotating assembly. On the top plane of the rotating block 602, two key actuating components are integrally formed or fixedly mounted: one is an arc-shaped, large-mass arc-shaped limiting block 603, and the other is an arc-shaped but smaller-radius actuating component 604. At the same time, on the top of the receiving frame 601, an L-shaped or fan-shaped drive component 605 is rotatably mounted via a horizontal rotating shaft. The top end of the drive component 605 is directly fixedly connected to the bottom center of the placement frame 5, so the rotation of the drive component 605 will directly drive the entire placement frame 5 to rotate. At the bottom of the support frame 601, a drive motor 606 is fixedly installed. The output shaft of the drive motor 606 is connected to the central shaft of the rotating block 602 through a gear set or a direct coupling, thereby driving the rotating block 602 to rotate at a uniform speed.

[0033] The more ingenious design lies in the structure of the drive component 605, such as Figure 2 and Figure 3As shown, several interlocking arc-shaped grooves 607 and several actuating grooves 608 are meticulously machined on the side facing the rotating block 602. The depth, width, and angle of these grooves are precisely calculated. Their working principle is as follows: When the drive motor 606 starts, it drives the rotating block 602, along with the arc-shaped limiting block 603 and the actuating element 604, to rotate slowly. When the arc-shaped limiting block 603 rotates with the rotating block 602 to a certain position, it fits precisely into one of the arc-shaped grooves 607 on the drive element 605. Since the arc-shaped outer surface of the arc-shaped limiting block 603 is completely in contact with the inner wall of the arc-shaped groove 607, it acts like a "pin" or "brake," preventing the drive element 605 from rotating around its own axis, thereby rigidly and stably locking the position of the placement rack 5 through the drive element 605. This braking state lasts for a period of time, precisely covering the entire process of the pressing assembly 4 completing the pressing, holding, and return strokes. As the rotating block 602 continues to rotate, the arc-shaped limiting block 603 slides out of the arc-shaped groove 607. Immediately afterwards, the adjacent actuating element 604 rotates into an actuating groove 608 on the driving element 605. The end of the actuating element 604 acts like a cam pusher, applying a force to the side wall of the actuating groove 608, generating a torque that instantly "pushes" the driving element 605 and its mounting frame 5 to rotate precisely by a fixed angle (e.g., 45 degrees each time if there are eight molds on the mounting frame). Afterward, the actuating element 604 slides out of the actuating groove 608, and the next arc-shaped limiting block 603 rotates into position and embeds itself into the next arc-shaped groove 607, again braking the mounting frame 5 to its new position. This cycle repeats continuously, perfectly achieving intermittent rotation and precise positioning of the mounting frame 5 through the intermittent contact between the arc-shaped limiting block 603 and the actuating element 604 and the driving element 605.

[0034] To ensure the synchronization of the entire system, the number of threaded grooves on the placement frame 5 for mounting mold 3 is exactly the same as the number of arc-shaped grooves 607 and actuating grooves 608 distributed circumferentially on the drive component 605. For example, if there are eight mold stations, the drive component 605 will also have eight arc-shaped grooves 607 and eight actuating grooves 608 to ensure that each mold can be accurately aligned with the pressing assembly 4 below.

[0035] To further improve the molding quality and demolding performance of toothpaste tablets, in another embodiment of this invention, annular heaters are cleverly integrated inside the placement frame 5, surrounding each threaded groove for mounting the mold 3. These heaters can be heating wires or micro-heating tubes, with precise temperature control via an external temperature control system. Before tablet pressing begins, the heaters can preheat the empty mold, maintaining its temperature within a suitable range (e.g., 40℃-60℃). The warm mold improves the physical properties of the injected toothpaste raw material, reducing its apparent viscosity and allowing it to fill every corner of the mold more smoothly and evenly under high pressure, thus avoiding defects such as air bubbles, insufficient material, or unclear edges in the finished product. Simultaneously, the preheated raw material exhibits a more compact molecular arrangement during pressing, resulting in better curing and higher density and hardness in the finished product, making it less prone to breakage during transportation or use.

[0036] Finally, to enhance the overall stability and safety of the equipment, a thick rubber pad 201 is fixedly installed at the bottom of each of the legs 2. This rubber pad 201 serves multiple purposes: firstly, it significantly increases the static friction between the legs 2 and the ground, effectively preventing displacement of the entire machine due to minor vibrations or accidental contact during operation; secondly, the rubber material itself has good elasticity and shock absorption, which can absorb and attenuate the vibrations and noise generated during equipment operation (especially during tablet pressing), creating a quieter working environment; thirdly, it prevents the metal legs from directly contacting and scratching the expensive epoxy flooring in laboratories or workshops, reflecting meticulous and human-centered design.

[0037] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
