Description

Technical Field

[0001] This utility model relates to the field of dual-station bag making machines, and in particular to a dual-station switching bag making machine for preparing modified packaging films. Background Technology

[0002] A dual-station bag-making machine is a highly efficient packaging machine with two independent work areas that can operate simultaneously. In one work area, the machine produces bags, including forming and cutting; while in the other work area, the produced bags are filled, sealed, cut, and sent to a prepared receiving device. Once the bags in the first work area are completed and sent to the receiving device, that area immediately begins producing the next bag, while the second work area continues with filling and sealing operations. The two work areas alternate, achieving a continuous and efficient production process.

[0003] In the current packaging machinery field, dual-station bag-making machines demonstrate higher production efficiency compared to traditional bag-making machines in practical use. Traditional bag-making machines often face the dilemma of slow production speed. These machines are typically designed for single-station operation, meaning they can only complete the production process of one bag at a time. From bag making, filling, sealing to cutting, each step must be performed sequentially, which undoubtedly limits the overall output speed. Especially under the demand for large-scale production, the efficiency bottleneck of single-station bag-making machines becomes increasingly apparent, making it difficult to meet the market's requirements for high-efficiency production.

[0004] Dual-station bag making machines significantly improve production efficiency by having two independent working areas simultaneously. However, station changeovers may be slower. Utility Model Content

[0005] The main objective of this invention is to provide a dual-station switching bag-making machine for preparing modified packaging films, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A dual-station switching bag making machine for preparing modified packaging film includes a base frame, a top frame, a telescopic device, a bag making mold, a discharge device, and a conveyor belt. The top frame is located at the upper end of the base frame, and the conveyor belt, telescopic device, bag making mold, and discharge device are installed on the top frame from right to left.

[0008] The right ends of the top frame and the bottom frame are connected to the mounting bracket via connecting brackets. The outer end of the mounting bracket is provided with an upper side frame and a lower side frame. Multiple guide rollers are installed between the upper side frame and the lower side frame. A first mounting roller is installed at the bayonet of the two upper side frames, and a second mounting roller is installed at the bayonet of the two lower side frames. The first mounting roller is connected to a first storage cylinder via a limiting sleeve, and the second mounting roller is connected to a second storage cylinder via a limiting sleeve. The modified packaging film is wound up through the first storage cylinder and the second storage cylinder, and the modified packaging film is stably fed into the work station for bag making operation through the guide rollers and the conveyor belt.

[0009] A film cleaning component is installed at the inner end of the mounting bracket. The modified packaging film on the first and second storage cylinders passes through the film cleaning component to achieve the cleaning and dust removal operation of the modified packaging film.

[0010] The connecting bracket is bolted to the top frame and the bottom frame. The upper and lower connecting brackets are fixed together by a support rod, forming an "H" shape. The side of the mounting bracket is designed as a triangular flag. The mounting bracket is fixed to the connecting bracket, the upper frame, and the lower frame by bolts. The outer ends of the first mounting roller and the second mounting roller are connected to a driving device, which drives them to rotate.

[0011] Among them, multiple guide rollers are mounted on the upper and lower side frames via bearings. Bolts are connected to the bayonet of the upper side frame and are connected to the first mounting roller via bolts. The first mounting roller is threadedly connected to a limiting sleeve.

[0012] The lower frame has a bolt at the bayonet and is connected to the second mounting roller via the bolt. The second mounting roller is threadedly connected to another limiting sleeve.

[0013] The first and second storage tubes are designed in the shape of an "I". The first and second storage tubes are threadedly connected to the limiting sleeve. The storage tubes can be quickly switched through the limiting sleeve, the mounting roller and the side frame bayonet, which makes it easy to switch between storage tubes of different specifications.

[0014] The film cleaning component consists of a guide roller, an adjusting bolt, a cleaning cloth, an installation strip, and a bracket. The installation strip is installed on the bracket by the adjusting bolt, the guide roller is placed on the bracket, and the cleaning cloth is connected to the installation strip. The modified packaging film passes through the guide roller and comes into contact with the cleaning cloth to achieve the cleaning operation.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The quick-change storage mechanism, through the cooperation of the limiting sleeve, installation roller, and side frame bayonet, enables rapid switching of storage cylinders. This design improves the flexibility and applicability of the equipment. Operators can quickly change storage cylinders of different specifications according to production needs without tedious adjustments and reinstallation, thus saving valuable time and improving production efficiency.

[0017] The guide rollers and conveyor belt in the transport mechanism work together to ensure that the modified packaging film can be stably and smoothly fed into the workstation for bag making. This design not only ensures the continuity of production but also effectively avoids damage and waste of the packaging film during transport, further improving product quality and production efficiency.

[0018] The seamless integration of the quick-change storage and conveying mechanisms makes the entire bag-making process more automated and intelligent. Operators only need to perform simple operations to change the storage tubes and transfer the packaging film, reducing labor intensity and improving work convenience and comfort.
