Description

Technical Field

[0001] The utility model belongs to the technical field of plastic lunch box production, and particularly relates to a feeding component for producing plastic lunch boxes. Background Art

[0002] In the lunch box production process, the first step is to put the PP granules into the material tank to ensure sufficient raw materials during the extrusion process; the lunch boxes made with PP plastic granules have good heat resistance and oil resistance, are suitable for loading hot food or greasy food, are not easy to deform or leak, and can be designed to be recyclable or use degradable PP materials to reduce the impact on the environment.

[0003] Many of the existing feeding facilities for PP plastic granules use manual handling of packaging bags, which are cut open and then poured into the hopper. Usually, the plastic granules are manually held and then cut with a blade. This process consumes a lot of physical strength and greatly increases manual fatigue to maintain the supply of raw materials. In addition, after the traditional PP plastic granules are fed, they need to be dusted in a dust removal tank. On the one hand, this increases the equipment cost investment, and on the other hand, the equipment takes up a lot of space and energy consumption, and cannot achieve integrated dust removal. Utility Model Content

[0004] The purpose of the present invention is to provide a feeding component for the production of plastic lunch boxes, which can integrate feeding and dust removal in the same device, thereby reducing the equipment procurement cost on the one hand and reducing the occupied space on the other.

[0006] A feeding assembly for producing plastic lunch boxes comprises a hopper which is inclined downward, a feeding pipe being fixedly connected to the bottom end of the hopper, a filter plate being fixedly connected to the inner wall of the hopper, a bag opening assembly being arranged on the upper side of the filter plate in the inner cavity of the hopper, a material guiding assembly being arranged in the inner cavity of the feeding pipe, an annular plate being arranged near the bottom end of the inner wall of the hopper, the annular plate being inclined downward, and a dust removal assembly being arranged near the top end in the inner cavity of the feeding pipe.

[0007] The bag opening assembly includes a support plate fixedly connected to the inner wall of the hopper, the support plate is arranged in a cross shape, four arc plates are arranged at the center of the top surface of the support plate, the side walls of the arc plates are fixedly connected with blades, four cylinders are evenly fixedly connected to the top surface of the support plate, and the output ends of the cylinders are fixedly connected to the arc plates.

[0008] The material guiding assembly includes two transmission rollers rotatably connected to the inner wall of the discharge pipe, a conveyor belt is sleeved between the two transmission rollers, a plurality of paddles are fixedly connected to the side wall of the conveyor belt, a motor is fixedly connected to the rear side wall of the discharge pipe, and the motor output shaft is fixedly connected to one of the transmission rollers.

[0009] The dust removal assembly includes a hollow plate fixedly connected to the inner wall of a feed pipe, a plurality of micro-holes are opened on the top surface of the hollow plate, a fan is fixedly installed on the right side wall of the feed pipe, an air inlet end of the fan is connected to the hollow plate, and a dust bag is installed on the air outlet end of the fan.

[0010] A material guide plate is fixedly connected to the left inner wall of the feeding tube.

[0011] A cone structure is formed between the four arc-shaped plates.

[0012] The technical effects achieved by this utility model are:

[0013] The practical feeding component for producing plastic lunch boxes integrates bag opening, feeding and dust removal through the cooperation between a hopper, a feeding pipe, a bag opening component, a material guiding component and a dust removal component. After the PP plastic particles are fed and processed, they can be directly put into production without being processed in a dust removal tank. This can reduce the purchase cost of the dust removal equipment and the space occupied by the equipment, thereby achieving the effect of convenient and efficient feeding.

[0021] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0022] like Figure 1-Figure 5 As shown, a feeding assembly for producing plastic lunch boxes includes a hopper 1, which is inclined downward, a feeding tube 2 is fixedly connected to the bottom end of the hopper 1, a filter plate 3 is fixedly connected to the inner wall of the hopper 1, and the filter plate 3 can filter out impurities and debris remaining on the packaging bag, a bag opening assembly is provided on the upper side of the filter plate 3 in the inner cavity of the hopper 1, a material guiding assembly is provided in the inner cavity of the feeding tube 2, an annular plate 17 is provided near the bottom end of the inner wall of the hopper 1, the annular plate 17 is inclined downward, and a dust removal assembly is provided near the top of the inner cavity of the feeding tube 2.

[0023] like Figure 1 and Figure 4 As shown, the bag opening assembly includes a support plate 4 fixedly connected to the inner wall of the hopper 1, the support plate 4 is arranged in a cross shape, four arc plates 6 are arranged at the center of the top surface of the support plate 4, blades 7 are fixedly connected to the side walls of the arc plates 6, four cylinders 5 are evenly fixedly connected to the top surface of the support plate 4, and the output ends of the cylinders 5 are fixedly connected to the arc plates 6. A conical structure is formed between the four arc plates 6.

[0024] Specifically, when the packaging bag is placed on the filter plate 3, the conical structure formed by the arc plate 6 can be inserted into the packaging bag, and then the cylinder 5 retracts to drive the blade 7 to move, cutting the packaging bag to form a cross opening, so that the plastic particles can fall quickly.

[0025] like Figure 3 and Figure 5 As shown, the material guiding assembly includes two transmission rollers 8 rotatably connected to the inner wall of the discharge tube 2, a conveyor belt 9 is sleeved between the two transmission rollers 8, a plurality of paddles 10 are fixedly connected to the side wall of the conveyor belt 9, a motor 13 is fixedly connected to the rear side wall of the discharge tube 2, and the output shaft of the motor 13 is fixedly connected to one of the transmission rollers 8.

[0026] The interval between the paddle plate 10 and the lower hollow plate 11 is smaller than the diameter of the plastic particles, so as to push the plastic particles on the hollow plate 11 to the left and prevent the plastic particles from being blocked by the pressure of the micropores 12 .

[0027] like Figure 3 and Figure 5 As shown, the dust removal assembly includes a hollow plate 11 fixedly connected to the inner wall of the feed pipe 2, a plurality of micropores 12 are provided on the top surface of the hollow plate 11, a fan 14 is fixedly installed on the right side wall of the feed pipe 2, the air inlet end of the fan 14 is connected to the hollow plate 11, and a dust bag 15 is installed on the air outlet end of the fan 14.

[0028] Among them, the diameter of the micropores 12 is much smaller than the diameter of the plastic particles, and is mainly used to adsorb dust, fine particles and impurities to avoid the plastic particles being mixed with a lot of impurities; in addition, the principle and installation method of the dust bag 15 are existing mature technologies and will not be described in detail in this solution.

[0029] like Figure 3 As shown, the left inner wall of the feeding tube 2 is fixedly connected with a guide plate 16. By setting the guide plate 16, the plastic particles can be kept in the middle position when the dust collection is completed and the material is discharged, thereby improving and reducing the problems such as the breakage caused by the collision of the plastic particles and the feeding tube 2.

[0030] The working principle of the utility model is as follows: firstly, the plastic particles are placed on the filter plate 3 together with the packaging bag, and the conical structure formed by the arc plate 6 is inserted into the packaging bag, and then the cylinder 5 is started to drive the arc plate 6 to move in four directions, and the packaging bag is cut by the blade 7, so that the plastic particles can pass through the filter plate 3 and enter the hopper 1;

[0031] At this time, the motor 13 is started to drive the transmission roller 8 to rotate, and the transmission roller 8 drives the paddle 10 to rotate through the conveyor belt 9, so as to transport the plastic particles to the lower hollow plate 11. At the same time, the fan 14 is started to generate negative pressure in the hollow plate 11, and the dust mixed in the plastic particles enters the hollow plate 11 through the micropores 12 and is collected in the dust bag 15. When suction is generated in the micropores 12 to adsorb the plastic particles, the plastic can be pushed as the paddle 10 rotates. After the plastic particles leave the hollow plate 11, they enter the discharge pipe 2 through the guide plate 16, so as to achieve the integrated filtering and dust removal treatment of the plastic particles.

[0032] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
