Description

Technical Field

[0001] This utility model relates to the technical field of automatic shelling machines for traditional Chinese medicine, and more specifically, to an anti-adhesion mold positioning device for automatic shelling machines for traditional Chinese medicine. Background Technology

[0002] The automatic shelling machine for traditional Chinese medicine is used for packaging traditional Chinese medicine. Its overall workflow is as follows: First, the lower shell is placed inside the slot of the mold. Then, the pills are compressed into uniform strips and fed into the lower shell. Next, the upper and lower shells are pressed together using a robotic arm or similar method. After pressing, the lower shell is pushed out of the mold's slot by an ejector pin. During this process, the mold provides precise positioning for the lower shell through its internal slots, ensuring accurate alignment and pressing of the upper and lower shells to form a sealed pill shell.

[0003] However, existing automatic shelling machines for Chinese herbal medicines have a significant problem in actual operation. After each shelling operation, the mold needs to push out the lower shell before reinstalling it for the next operation. Frequent reinstallation of the lower shell severely impacts the efficiency of the automatic shelling machine, increases the production cycle, and consequently limits the overall production scale and capacity of Chinese herbal medicine products. Therefore, designing an anti-sticking mold positioning device for automatic shelling machines of Chinese herbal medicines to reduce the time spent on each lower shell installation is of great significance for improving the production efficiency and market competitiveness of automatic shelling machines for Chinese herbal medicines. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model proposes an anti-adhesion mold positioning device for an automatic shelling machine for traditional Chinese medicine.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] The anti-adhesion mold positioning device of the automatic shelling machine for Chinese medicine includes a mold mounting base and a base plate. A guide rail is set on the base plate, and an electric slider is installed in the guide rail. A support rod is fixed on the top wall of the electric slider, and the other end of the support rod is fixed to the lower end face of the mold mounting base. Two mounting grooves are symmetrically arranged on the upper end face of the mold mounting base along its central axis, and the two mounting grooves penetrate the mold mounting base.

[0007] The electric slider controls the left and right movement of the mold mounting base. As one mold is performing the shell-fitting operation at the shell-fitting station, the other mold can accurately leave the shell-fitting station. The mold leaving the shell-fitting station pushes out the already-fitted lower shell and installs the new lower shell into the slot in the mold mounting base. Once the mold performing the shell-fitting operation completes its work, the electric slider quickly moves the prepared other mold to the shell-fitting station. This cycle repeats, ensuring the continuity of the shell-fitting operation.

[0008] This device uses an electric slider to control the molds to quickly and alternately enter the shell-closing station. While one mold is closing the shell, another mold is preparing to replace the lower shell, which almost eliminates the waiting time in the shell-closing process, greatly improving production efficiency and increasing the number of shells closed per unit time to meet the market demand for Chinese medicine products.

[0009] Preferably, the mold mounting base is provided with an overlapping ring located at the bottom opening of the mounting groove, and the upper end face of the mold mounting base is provided with a limiting plate and a resetting device. When there is no external force, the limiting plate extends into the upper part of the mounting groove under the action of the resetting device, and the overlapping ring and the limiting plate are respectively attached to the upper and lower end faces of the mold mounting base.

[0010] The overlapping ring on the mold mounting base is located at the bottom opening of the mounting groove. When the mold is installed, the bottom of the mold can fit tightly against the overlapping ring, providing bottom support and initial positioning for the mold, ensuring its relative stability within the mounting groove. Simultaneously, the upper surface of the mold mounting base is equipped with a limiting plate and a resetting device. When no external force is applied, the limiting plate naturally extends into the upper part of the mounting groove under the elastic force of the resetting device or other resetting action. At this time, the limiting plate fits against the upper surface of the mold mounting base and cooperates with the overlapping ring, limiting the mold from both above and below, thus firmly fixing the mold within the mounting groove. During the operation of the shell-fastening machine, even under external forces such as vibration, the mold is unlikely to shift, ensuring the accuracy of the shell-fastening operation. When mold replacement or maintenance is required, external force is applied to the limiting plate to overcome the force of the resetting device, causing the limiting plate to move away from the upper part of the mounting groove, thereby releasing the restriction on the upper part of the mold.

[0011] Preferably, the reset device includes two parallel mounting plates, a limiting plate is disposed between the two mounting plates, and a reset groove is provided on the side wall of the mounting plate for the limiting plate to extend into. The reset groove is open on the side near the mounting groove, and a spring is fixed on the side wall of the reset groove away from the mounting groove. The other end of the spring is fixed on the side wall of the limiting plate.

[0012] As a reset power source, the spring can provide stable and adjustable elastic force, ensuring that the limit plate can accurately reset to the initial limit position each time, and reliably limit the mold.

[0013] As a preferred option, a pull ring is provided at the upper end of the limiting plate.

[0014] The pull ring at the upper end of the limit plate is mainly for the convenience of operators applying external force to the limit plate. When it is necessary to remove or replace the mold, the operator does not need to directly move the limit plate by hand; simply pulling the pull ring will easily move the limit plate against the spring force, moving it along the reset groove away from the mounting groove, thereby releasing the mold from its position. After the operation is completed, releasing the pull ring will cause the limit plate to automatically reset under the action of the spring.

[0015] As a preferred embodiment, two limiting plates are provided and symmetrically arranged on both sides of the central axis of the mounting groove, and two corresponding reset devices are also provided.

[0016] The symmetrical arrangement of the double-sided limiting plates and the reset device allows for the uniform application of limiting force to the mold from both sides of the central axis of the mounting groove. Compared to single-sided limiting, this method can better resist external forces and vibrations from different directions. During the operation of the shell-fastening machine, regardless of the direction of impact force on the mold, the double-sided limiting effectively prevents the mold from shifting, tilting, or shaking, greatly enhancing the stability of mold installation and further improving the accuracy of the shell-fastening operation and the stability of product quality.

[0017] Preferably, the guide rail has sensing grooves on its left and right side walls, each containing a microswitch extending out of the groove. When the electric slider abuts against the side wall of the sensing groove, the corresponding sensing switch is activated by pressure. An indicator light is also provided on the base plate; the indicator light illuminates when the sensing switch is activated by pressure.

[0018] Indicator lights provide operators with a clear indication of whether the mold mounting base has reached the correct position. During equipment operation, the electric slider moves the mold mounting base, and operators can quickly determine whether the mold has moved to the appropriate position for shell-fitting by observing the indicator lights. This avoids shell-fitting errors caused by inaccurate positioning, improves the accuracy of shell-fitting operations, and ultimately enhances product quality. Attached Figure Description

[0025] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative of this utility model and are not intended to limit it.

[0026] Example

[0027] like Figures 1-4 As shown, the anti-sticking mold positioning device of the automatic herbal shelling machine mainly consists of three parts:

[0028] The movable support section consists of a base plate 120 as the basic load-bearing structure, on which a guide rail 1201 is mounted. An electric slider 1202 is installed inside the guide rail 1201. A support rod 1203 is vertically fixed to the top wall of the electric slider 1202. The other end of the support rod 1203 is tightly connected to the lower end face of the mold mounting base 110, forming a drive and support system that allows the mold mounting base 110 to move left and right.

[0029] Mold mounting section: Two through mounting grooves 1101 are symmetrically distributed along the central axis on the upper end face of the mold mounting base 110. An overlapping ring 130 is provided at the bottom opening of each mounting groove 1101. A limiting plate 140 and a resetting device are also provided on the upper end face of the mold mounting base 110. The resetting device includes two parallel mounting plates 150, with the limiting plate 140 located between the two mounting plates 150. A resetting groove 1501 is machined on the side wall of the mounting plate 150. The groove opens on the side closest to the mounting groove 1101, and a spring 1502 is fixed to the side wall away from the mounting groove 1101. The other end of the spring 1502 is connected to the side wall of the limiting plate 140. There are two limiting plates 140, symmetrically arranged on both sides of the central axis of the mounting groove 1101, and correspondingly, two resetting devices. In addition, a pull ring 1401 is installed at the upper end of the limiting plate 140.

[0030] Position sensing component: Sensing slots 160 are respectively formed on the left and right side walls of the guide rail 1201. A microswitch 1601, which can extend out of the slot, is installed within each sensing slot 160. The microswitch 1601 can retract into the sensing slot 160 under the action of the electric slider 1202. An indicator light is provided on the base plate 120. The indicator light is prior art, and its specific structure and circuit connection are not shown in the diagram and will not be described in detail here. This indicator light is electrically connected to the microswitch 1601 within the sensing slot 160.

[0031] Its specific operating principle is as follows:

[0032] When installing the mold, align the bottom of the mold with the overlapping ring 130 at the bottom opening of the mounting groove 1101 to achieve initial positioning and bottom support of the mold. At this time, the spring 1502 in the reset device is in a naturally extended state, pushing one end of the limiting plate 140 into the upper part of the mounting groove 1101. Since the limiting plates 140 are symmetrically distributed on both sides of the central axis of the mounting groove 1101, they work together with the overlapping ring 130 to form a firm limit on the mold from both the top and bottom, so that the mold can be firmly fixed in the mounting groove 1101. This ensures that the mold can resist external forces such as vibration during the operation of the shell-fastening machine, maintain a stable position, and ensure the accuracy of the shell-fastening operation. When it is necessary to replace the mold or perform maintenance, the operator pulls the pull ring 1401 at the upper end of the limiting plate 140 to apply external force to the limiting plate 140, overcoming the elastic force of the spring 1502, so that the limiting plate 140 moves along the reset groove 1501 away from the mounting groove 1101, thereby releasing the limiting restraint on the mold, and the mold can then be easily removed. After completing the relevant operations, release the pull ring 1401, and the spring 1502 will drive the limit plate 140 to automatically return to the initial limit position, preparing for the next mold installation.

[0033] The electric slider 1202 moves left and right within the guide rail 1201 according to a preset program or operating instructions, thereby driving the mold mounting base 110 to move synchronously. When one mold is in the shell-fitting station for shell-fitting operations, the electric slider 1202 will drive the mold mounting base 110 to move, causing the other mold to leave the shell-fitting station. During the movement of the leaving mold, it pushes out the already-fitted lower shell and installs a new lower shell in the slot of the mold mounting base 110. When the mold that is currently fitting the shell completes its operation, the electric slider 1202 quickly moves the other prepared mold to the shell-fitting station, and so on, alternating to achieve continuous shell-fitting operations.

[0034] During the movement of the electric slider 1202 driving the mold mounting base 110, when the electric slider 1202 abuts against the side wall of the sensing groove 160 on the side wall of the guide rail 1201, it will press the micro switch 1601 inside the sensing groove 160. The micro switch 1601 is activated under pressure, thereby triggering the indicator light on the connected base plate 120 to illuminate. By observing the on / off state of the indicator light, the operator can intuitively and quickly determine whether the mold mounting base 110 has moved to the correct position, so as to perform the shell-fastening operation in a timely manner.

[0035] The above setup enables rapid, staggered switching of molds at the shell-closing station via an electric slider 1202. While one mold is closing the shell, another mold is preparing to replace it, virtually eliminating waiting time during the shell-closing process and significantly improving production efficiency. The number of shells closed per unit time has increased significantly, effectively meeting market demand for traditional Chinese medicine products and enhancing the company's production efficiency.

[0036] The overlapping ring 130 on the mold mounting base 110 works in conjunction with the symmetrically positioned plates 140 on both sides and the reset device to apply a limiting force to the mold evenly from multiple directions. Compared with unilateral limiting, this can better resist external forces and vibrations from different directions. During the operation of the shell-fastening machine, regardless of the complex working conditions encountered, it can effectively prevent the mold from shifting, tilting, or shaking, significantly enhancing the stability of mold installation, thereby improving the accuracy of the shell-fastening operation and the stability of product quality, and reducing the defect rate.

[0037] In summary, the above are merely preferred embodiments of this embodiment. All equivalent changes and modifications made in accordance with the scope of the patent application of this embodiment shall fall within the scope of the patent of this embodiment.
