Description

Technical Field

[0001] The utility model relates to the technical field of packaging machinery, in particular to a semi-automatic stopper inserting machine for soft bags. Background Art

[0002] A soft bag generally refers to a bag made of soft materials. The materials for making soft bags are diverse, and common ones include plastics (such as polyethylene, polypropylene, etc.), non-woven fabrics, paper, etc. These materials are flexible and can be deformed according to the shape of the items contained. Soft bags are used in various packaging fields, such as for packaging various snacks, seasonings, liquid beverages, etc. For example, for packaging medicines such as oral liquids and eye drops. For example, for packaging shampoos, body washes, etc.

[0003] After the soft bag is filled with items, a stopper needs to be inserted at the bag mouth to ensure its sealing performance.

[0004] In the prior art, there are mainly two ways to install the soft bag stopper:

[0005] 1. Rely on manual installation. Manually put the stoppers into the soft bag mouths one by one, and then fix them by pressing or other means. Due to manual operation, the speed is slow and it is difficult to meet the requirements of large-scale production.

[0006] 2. Rely on fully automatic devices for installation. These devices can automatically complete a series of operations such as the conveying, positioning, supply, and installation of soft bags and stoppers, greatly improving production efficiency and quality stability. However, the price of fully automatic devices is expensive, and for some small and medium-sized enterprises, the cost of purchasing and maintaining such equipment is too high to bear. Moreover, the structure of fully automatic devices is complex, and the technical requirements for operators and maintenance personnel are relatively high, and special training is required.

[0007] In order to address the above problems, a semi-automatic stopper inserting machine for soft bags is proposed herein. Content of the Utility Model

[0008] The purpose of the utility model is to solve the drawbacks existing in the prior art, and a semi-automatic stopper inserting machine for soft bags is proposed.

[0009] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0010] Semi-automatic stopper inserting machine for soft bags, including a base, a placing rack is provided on the base, a placing opening is provided on the placing rack, a circular blanking opening is further provided in the placing opening on the placing rack, an extrusion mechanism for extruding stoppers is further provided on the placing rack, a rotating rack is rotatably provided on the base, a driving motor is provided on the base, and the driving motor is connected to the rotating rack through a rotating mechanism. Three fixing racks are installed on the rotating rack, and two sliding plates are slidably sleeved on each fixing rack through an elastic mechanism. Clamping blocks are installed on both sliding plates, and the sliding plates are connected to the rotating rack through a stabilizing mechanism.

[0011] Preferably, the extrusion mechanism includes a mounting rack provided on the placing rack, a cylinder is installed on the mounting rack, and a rubber pad is installed on the telescopic end of the cylinder.

[0012] Preferably, the rotating mechanism includes a gear provided on the output shaft of the driving motor, a toothed ring is installed on the rotating rack, and the gear meshes with the toothed ring.

[0013] Preferably, the elastic mechanism includes a spring sleeved on the fixing rack, and the spring is elastically connected to the two sliding plates.

[0014] Preferably, the stabilizing mechanism includes a stabilizing rod installed on the sliding plate, and a stabilizing groove corresponding to the stabilizing rod is provided on the rotating rack.

[0015] Preferably, the vertical sectional view of the placing opening is in a T shape, and the inner bottom wall of the placing opening is inclined towards the blanking opening.

[0016] Advantages of the present utility model:

[0017] 1. Compared with manual installation, the semi-automatic stopper inserting machine for soft bags can significantly improve the speed of stopper installation. The driving motor drives the rotating rack to rotate through the rotating mechanism, and each time a soft bag can be accurately moved to the stopper inserting position. At the same time, the cylinder can quickly extrude the stopper into the bag mouth of the soft bag, greatly shortening the stopper inserting time.

[0018] 2. Compared with the installation of fully automatic equipment, the overall structure of the device is relatively simple, and the multiple components constituting the device are very common in the market. The whole has the advantages of easy operation and easy maintenance, and does not require too high cost while improving efficiency.

[0019] 3. The device has multiple clamping stations, which can be used by multiple people to simultaneously complete feeding and discharging, improving the practicability of the device. Description of the drawings

Specific implementation mode

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0027] Refer to Figures 1-5 , a semi-automatic plugging machine for soft bags, including a base 1, a placement rack 2 is provided on the base 1, a placement opening 3 is provided on the placement rack 2, a circular blanking opening 16 located in the placement opening 3 is further provided on the placement rack 2, and an extrusion mechanism for extruding the plugs is further provided on the placement rack 2. A rotating rack 6 is rotatably provided on the base 1, a driving motor 13 is provided on the base 1, the driving motor 13 is connected to the rotating rack 6 through a rotating mechanism, three fixing frames 7 are installed on the rotating rack 6, and two sliding plates 8 are slidably sleeved on each fixing frame 7 through an elastic mechanism. Clamping blocks 10 are installed on both sliding plates 8, and the sliding plates 8 are connected to the rotating rack 6 through a stabilizing mechanism.

[0028] The extrusion mechanism includes a mounting rack 4 provided on the placement rack 2, a cylinder 5 is installed on the mounting rack 4, and a rubber pad is installed on the telescopic end of the cylinder 5. When the cylinder 5 is started, the plug that has moved into the blanking opening 16 and has not fallen can be extruded downwards and into the bag mouth of the soft bag.

[0029] The rotating mechanism includes a gear 14 provided on the output shaft of the driving motor 13, a gear ring 15 is installed on the rotating rack 6, and the gear 14 meshes with the gear ring 15. With the help of the above-mentioned gear 14 and gear ring 15, the power transmission of the driving motor 13 is realized, and multiple soft bags can be driven to rotate so as to correspond to the blanking opening 16 on the placement rack 2. Each time the driving motor 13 drives the rotating rack 6 to rotate, the rotation amplitude is 60 degrees.

[0030] The elastic mechanism includes a spring 9 sleeved on a fixed frame 7, and the spring 9 is elastically connected to two sliding plates 8. The elastic potential energy provided by the spring 9 realizes the dragging of the two sliding plates 8, so as to cooperate with the clamping blocks 10 to clamp the soft bag.

[0031] It should be noted that: the clamping blocks 10 are arc-shaped and both ends are rounded and polished. Therefore, when the distance between the two clamping blocks 10 is small, the mouth part of the soft bag can be directly inserted between the two clamping blocks 10, and the two clamping blocks 10 are automatically separated. After the mouth part of the soft bag completely enters between the two clamping blocks 10, the spring 9 will drive the sliding plate 8 and the clamping blocks 10 to complete the clamping of the soft bag.

[0032] The stabilizing mechanism includes a stabilizing rod 11 installed on the sliding plate 8, and a stabilizing groove 12 corresponding to the stabilizing rod 11 is provided on the rotating frame 6. The stabilizing rod 11 is L-shaped and the end is located in the stabilizing groove 12, realizing the support of the sliding plate 8 and the soft bag.

[0033] The vertical cross-sectional view of the placing port 3 is T-shaped, and the inner bottom wall of the placing port 3 is inclined towards the blanking port 16. The T-shaped design conforms to the shape of the plug, avoiding the plug from falling vertically from the placing port 3. The inclined setting is conducive to the plugs stacked in the placing port 3 gradually moving towards the blanking port 16. There is friction between the inner wall of the blanking port 16 and the outer wall of the plug, and it will not fall from the blanking port 16 without the downward pressure of the air cylinder 5.

[0034] When the present utility model is in use, the mouth of the soft bag is inserted between the clamping blocks 10. The clamping blocks 10 are arc-shaped and the ends are rounded and polished. After the mouth enters, they are separated. After it completely enters, the spring 9 drives the sliding plate 8 and the clamping blocks 10 to clamp the soft bag. Subsequently, the driving motor 13 on the base 1 is started, and the output shaft gear 14 meshes with the gear ring 15 of the rotating frame 6 to drive the rotating frame 6 to rotate. Each rotation amplitude is 60 degrees to make the soft bag correspond to the blanking port 16 of the placing frame 2 and wait to insert the plug.

[0035] Before that, multiple plugs are arranged and placed in the placing port 3 of the placing frame 2, and the plug at the end is in the blanking port 16 and is about to fall. At this time, the air cylinder 5 is started to press down on the plug, and then it falls vertically into the mouth of the soft bag below to complete the installation.

[0036] Due to the setting of three clamping stations, each device can be operated by two people at the same time. One is responsible for taking down the soft bag with the plug inserted, and the other is responsible for installing the soft bag without the plug inserted.

[0037] The above is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
