Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermoplastic machine technology, and specifically to a feeding device for a thermoplastic machine. Background Technology
[0002] A thermoforming machine is an industrial piece of equipment used to heat and shape thermoplastic materials, widely used in the plastics processing industry. This equipment heats thermoplastics to their softening point using heating elements, making them easier to mold and process. Thermoforming machines are typically equipped with molds that can press, extrude, or inject plastic material into specific shapes, which then solidify upon cooling into the final product. Because thermoplastic materials can be heated and reshaped multiple times, thermoforming machines offer significant advantages in production efficiency, material utilization, and product design flexibility, and are widely used in industries such as packaging, automotive, electronics, and construction.
[0003] Currently, the loading process of thermoforming machines relies on workers manually lifting heavy rolls of material onto the rack. This heavy-duty handling leads to high labor intensity for workers, easily causing physical fatigue, and also poses safety hazards, potentially resulting in worker injuries or equipment damage. Furthermore, manual loading is inefficient, time-consuming, and negatively impacts the overall operation of the production line. Utility Model Content

[0006] A frame with two storage rods spaced apart on it, and each storage rod is equipped with a slanted rail.
[0007] A lifting frame includes a connecting rod and lifting plates disposed at both ends of the connecting rod. The lifting plates include a hinge part that is hinged to the frame, a first positioning part that is adapted to the material shaft, and a slide rail part.
[0008] The first limiting frame has its rear end hinged to the storage rod, and a second positioning part adapted to the material shaft is provided on it;

[0011] The second driver is hinged to the front end of the first limiting frame. Under its drive, the first limiting frame has a working position and a material changing position. When in the working position, the material shaft rotates at the second positioning part to output the sheet. When in the material changing position, the material shaft slides into the third positioning part along the inclined rail part at the second positioning part.
[0012] In some embodiments, the first limiting frame includes two limiting plates spaced apart and two rollers spaced apart between the two limiting plates, with the material shaft located between the two rollers.
[0013] In some embodiments, the second positioning part is an arc-shaped groove disposed on the limiting plate, and the rear end of the arc-shaped groove extends upward.
[0014] In some embodiments, when the first limiting frame is in the working position, the lower end of the limiting plate abuts against the frame.
[0015] In some embodiments, the first driver and the second driver are pneumatic cylinders, electric actuators, or hydraulic cylinders.
[0016] In some embodiments, there are two first drivers, which are connected to two lifting plates respectively via their drive shafts.

[0020] In some embodiments, the frame includes a feeding end and a discharging end. The discharging end is provided with a first roller shaft, which is rotatably mounted on the frame and connected to a drive motor at one end. A slide rail is provided above both ends of the first roller shaft at the discharging end. A slider is provided in the slide rail, and a second roller shaft is rotatably mounted on the two sliders.

[0031] The following description provides specific application scenarios and requirements for this specification, intended to enable those skilled in the art to make and use the contents of this specification. Various partial modifications to the disclosed embodiments will be apparent to those skilled in the art, and the general principles defined herein can be applied to other embodiments and applications without departing from the spirit and scope of this specification. Therefore, this specification is not limited to the embodiments shown, but rather to the widest scope consistent with the claims.
[0032] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "longitudinal", "lateral", "radial", "length", "width", "thickness", "upper", "lower", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are mainly for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element or component to have a specific orientation, or to be constructed and operated in a specific orientation.
[0033] Secondly, the terms "first," "second," and similar words do not indicate any order, quantity, or importance, but are merely used to distinguish different components and should not be construed as limiting the embodiments of this application.
[0034] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral constructions; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium, or internal connections between two devices, components, or parts.
[0035] Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0036] Regarding the accompanying drawings of this application, it should be clearly understood that the drawings are for illustrative and descriptive purposes only and are not intended to limit the scope of this specification. It should also be understood that the drawings are not necessarily drawn to scale.
[0037] like Figures 1 to 8 As shown in the figure, this specification provides a feeding device for a thermoplastic machine for feeding roll materials. Conventional roll materials include a material spool and a sheet wound on the material spool. The feeding device includes a frame 1, a lifting frame 2, a first limiting frame 3, a first driver 4, a second limiting frame 5, and a second driver 6.
[0038] The lifting frame 2 includes a connecting rod 200 and lifting plates 201 disposed at both ends of the connecting rod 200. The lifting plate 201 includes a hinge part 202 hinged to the frame 1, a first positioning part 203 adapted to the material shaft, and a slide rail part 204. Figure 2 As shown, the lifting plate 201 is triangular, and the first positioning part 203 is an arc-shaped groove formed by extending and bending one corner of the lifting plate 201. It is necessary to ensure the transition between the arc-shaped groove and the slide rail part 204 so that the material shaft can smoothly slide into the slide rail part 204.
[0039] Two storage rods 7 are spaced apart on the frame 1. The rear end of the first limiting frame 3 is hinged to the storage rod 7, and a second positioning part 300 adapted to the material shaft is provided on it. The second limiting frame 5 is located at the rear end of the storage rod 7 and is provided with a third positioning part 500 adapted to the material shaft. The storage rod 7 is provided with a inclined rail part 700. The inclined rail part 700 is inclined downward from the second positioning part 300 to the third positioning part 500, that is, the material shaft can slide into the third positioning part 500 along the inclined rail part 700. Generally, the inclination angle of the inclined rail part 700 is 10°-20°.
[0040] The first driver 4 is used to drive the lifting frame 2 to rotate around its hinge point so that the material shaft slides into the second positioning part 300 along the slide rail part 204 from the first positioning part 203. It can be understood that the first driver 4 is a cylinder, an electric push rod, or a hydraulic cylinder.
[0041] Thus, during loading, simply move both ends of the roll material roller above the first positioning part 203 of the two lifting plates 201, and drive the first driver 4 to lift the roll material and slide it into the second positioning part 300. The material shaft can then rotate within the second positioning part 300 to output the sheet material. Generally, heavier roll materials can be forked onto the lifting frame 2 using a forklift.
[0042] The second driver 6 is hinged to the front end of the first limiting frame 3. Under its drive, the first limiting frame 3 has a working position and a material changing position. When in the working position, the material shaft rotates at the second positioning part 300 to output the sheet. When in the material changing position, the material shaft slides along the inclined rail part 700 into the third positioning part 500 from the second positioning part 300. The second driver 6 is a pneumatic cylinder, an electric push rod, or a hydraulic cylinder.
[0043] With this setup, the used material shaft can be automatically unloaded and stored in the third positioning part 500, eliminating the need for manual unloading. This reduces the labor intensity of workers, decreases the probability of safety accidents, and improves the efficiency of material loading.
[0044] In some embodiments, the second positioning part 300 is an arc-shaped groove provided on the limiting plate 301. Since the rear end of the frame 1 is the discharge end, the rear end of the arc-shaped groove extends upward, so that the material shaft can rotate and output the sheet in the arc-shaped groove without being pulled forward. It should be noted that the arc-shaped groove cannot wrap too much around the material shaft. When the first limiting frame 3 is in the working position, the material shaft can smoothly slide into the arc-shaped groove and rotate and output the sheet therein. When the first limiting frame 3 is in the material changing position, the material shaft can smoothly slide into the inclined rail part 700.
[0045] Similarly, the third positioning part 500 is also an arc-shaped groove, but it is necessary to ensure that the material shaft can slide smoothly into the third positioning part 500.
[0046] In some embodiments, the first limiting frame 3 includes two spaced-apart limiting plates 301 and two rollers 302 spaced between the two limiting plates 301. The material shaft is located between the two rollers 302, and the two rollers 302 provide rolling support for the material shaft, enabling the material shaft to rotate and output sheet material, thereby improving the smoothness of material output.
[0047] When the first limiting frame 3 is in the working position, the lower end of the limiting plate 301 abuts against the frame 1. Thus, when the material shaft rotates at the second positioning part 300 to output the sheet, it is not supported by the second driver 6, but by the frame 1, to prevent damage to the second driver 6 due to excessive weight of the roll. It should be understood that there is a gap between the lower end of the roller 302 and the frame 1 to ensure smooth rotation.
[0048] In some embodiments, there are two first drivers 4, which are connected to two lifting plates 201 respectively via their drive shafts. The lifting capacity of the lifting frame 2 is enhanced by the dual drivers.
[0049] Secondly, a buffer block 8 is provided on the frame 1 corresponding to the connecting rod 200. The buffer block 8 is made of rubber. The end face of the buffer block 8 facing the connecting rod 200 is provided with an abutment groove that is compatible with the connecting rod 200. In this way, if the lifting frame 2 descends excessively, it will not impact the frame 1.
[0050] In some embodiments, the first driver 4 is a single unit and is connected to the connecting rod 200 via its drive shaft.
[0051] In some embodiments, such as Figure 5As shown, the lifting plate 201 also includes a first plate 9 and a second plate 10. The hinge part 202 is disposed on the first plate 9. The first driver 4 is connected to the first plate 9. The first positioning part 203 is an arc-shaped groove disposed on the second plate 10. The second plate 10 is provided with two rows of first adjustment holes 11. It should be understood that each row has at least one first adjustment hole 11. The first plate 9 is provided with several second adjustment holes 12 at intervals along the same straight line corresponding to each row of first adjustment holes 11. The first adjustment holes 11 are connected to different second adjustment holes 12 by fasteners so that the arc-shaped groove is at different heights, thus adapting to rolls of different diameters.
[0052] In some embodiments, such as Figure 6 As shown, both sides of the frame 1 are provided with receiving grooves 13. The two sides of the second limiting frame 5 are slidably arranged along the corresponding receiving grooves 13. For example, the two sides of the second limiting frame 5 are provided with sliders that slide and cooperate with the receiving grooves 13. A spring is provided between the second limiting frame 5 and the receiving grooves 13. When the material shaft slides into the third positioning part 500, the second limiting frame 5 moves down along the receiving grooves 13 and compresses the spring. In this way, multiple material shafts can be stored in the receiving grooves 13, and the spring and the second limiting frame 5 form elastic support for the material shafts, preventing the material shafts from falling directly into the receiving grooves 13 and causing damage.
[0053] The receiving slot 13 is vertically disposed on the frame 1, or the receiving slot 13 is inclinedly disposed on the frame 1 and tilted downward toward the rear end of the frame 1.
[0054] In some embodiments, such as Figure 7 and Figure 8 As shown, the frame 1 includes an infeed end and an outlet end. The outlet end is equipped with a first roller shaft 15, which is rotatably mounted on the frame 1 and connected to a drive motor 16 at one end. A slide rail 17 is located above both ends of the first roller shaft 15 at the outlet end. A slider 18 is disposed within the slide rail 17, and a second roller shaft 19 is rotatably mounted on the two sliders 18. A drive cylinder 20 for moving the sliders 18 is located at the upper end of the slide rail 17. It can be understood that the first roller shaft 15 and the second roller shaft 19 are rotatably connected by bearings. With this configuration, the drive motor 16 can pull the sheet material to the downstream device.
