Description

Technical Field

[0001] The utility model belongs to the technical field of feeding devices, and in particular relates to a feeding device for an injection molding machine. Background Art

[0002] Injection molding machine, also known as injection molding machine or injection machine, is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. Injection molding machines are widely used because they can form plastic products with complex shapes, precise dimensions or dense textures with metal inserts in one go.

[0003] In the production of some pharmaceutical packaging, injection molding is often used to produce medicine trays. The raw materials for producing medicine trays are wound rolls. During injection molding production, since the rolls are heavy, two workers are required to lift the rolls and place them on the feed rack after lifting them to a certain height. This process is not only labor-intensive, but also prone to safety accidents such as accidental slipping during transportation, which is not conducive to safe production. Utility Model Content

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] It should be noted that injection molding is used when producing the medicine packaging material medicine tray. The raw material used is in the form of long sheets, which are wound on the support shaft 41 to form a material roll 4. The material roll 4 is mounted on the feed rack 1 to feed the injection molding machine.

[0021] The specific embodiments are as follows:

[0022] Embodiment 1, as Figure 1-3 As shown, a feeding device for an injection molding machine includes a feeding rack 1, a lifting member, and a telescopic driving member 3. The feeding rack 1 includes two support plates 11 and a plurality of cross braces 12. The two support plates are arranged in parallel and spaced apart, and the cross braces 12 are used to connect the two support plates 11 to form a supporting frame; the cross braces 12 are distributed at the bottom of the support plate 11 and the end of the support plate 11 close to the injection molding machine, so that an open style is formed at the upper end of the feeding rack 1 and the end away from the injection molding machine, so that the material roll can be easily moved up and down on the feeding rack 1.

[0023] The lifting member and the telescopic driving member 3 are both connected to the feed rack 1, and the telescopic driving member 3 is used to drive the lifting member to rotate to complete the lifting of the material roll 4. The lifting member includes two triangular frames 2. The two triangular frames 2 are arranged in parallel and at intervals, and are respectively connected to the inner sides of the upper ends of the two support plates 11. The first corner of the upper end of the triangular frame 2 is connected to the support plate 11 through a rotating shaft 21. One end of the telescopic driving member 3 is rotatably connected to the second corner of the triangular frame 2, and the other end of the telescopic driving member 3 is rotatably connected to the support plate 11. A hook member 22 is provided at the third corner of the triangular frame 2, and the support shaft 41 of the material roll 4 is placed in the hook member 22 for limiting, so as to facilitate the lifting of the material roll 4.

[0024] In this embodiment, the triangular frame 2 adopts a right-angled triangle structure, and the second angle is located at a right angle of the triangular frame 2, so that the line connecting the first angle and the third angle constitutes a hypotenuse.

[0025] In this embodiment, the telescopic driving member 3 includes two telescopic cylinders. The two telescopic cylinders are rotatably connected to the inner sides of the two support plates 11 respectively, and are used to drive the two triangular frames 2 to rotate respectively.

[0026] In this embodiment, a downwardly concave rotation groove 111 is provided on the support plate 11, and the rotation groove 111 is located on the side of the rotating shaft 21 close to the injection molding machine. The rotation groove 111 is used for the support shaft 41 to be placed therein, and the support shaft 41 rotates in the rotation groove 111 during feeding.

[0027] In this embodiment, a stopper 112 protruding upward is provided on the side of the rotating groove 111 close to the injection molding machine. When the material roll 4 is feeding, the injection molding machine pulls the material roll 4 with a certain pulling force, so the stopper 112 plays a role of stopping and limiting, so as to prevent the material roll 4 from jumping out of the rotating groove 111, thereby improving the safety of use.

[0028] When the material roll 4 is in use, the support shaft 41 is higher than the hook 22. The staff can place the support shaft 41 above the hook 22 by pushing or slightly lifting it. At this time, the telescopic cylinder is started, and the telescopic cylinder is extended, so that the triangular linkage device composed of the contraction cylinder and the triangular frame 2 is deformed, and then the triangular frame 2 rotates around the rotating shaft 21, so that the hook 22 at the third corner rises upward, and the material roll 4 is lifted. When it is lifted to slightly above the upper end of the support plate 11, the staff assists in pushing or rolling the material roll 4 until the support shaft 41 enters the rotating groove 111, and the material loading operation can be realized. When the material roll 4 is small and the support shaft 41 is lower than the hook 22, the staff only needs to slightly lift the material roll 4 to place the support shaft 41 on the hook 22, and then the material roll 4 can be lifted. In this way, no matter what the material roll 4 is, the staff only needs to slightly lift the material roll 4, without much labor, which not only saves labor, but also reduces the safety accidents that are easy to occur when the material roll 4 is manually lifted, and ensures safe production.

[0029] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
