Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a packaging equipment. Background Art

[0002] The food packaging process includes filling, wrapping, sealing and other major processes, as well as related processes before and after. The traditional packaging method is to weigh the food manually, then put the weighed food into the packaging bag and seal it. This manual operation has very low production efficiency.

[0003] Based on the above reasons, most of the existing enterprises use packaging machines to replace them in order to improve their production efficiency. However, in the existing packaging equipment, generally only one production line can be used for packaging production, so the overall floor space is large, and the production efficiency is still limited. In addition, the existing packaging equipment only uses valves as the opening and closing switches, especially some small granular and powdered foods are easily squeezed and agglomerated, which causes blockage during packaging. Utility Model Content

[0004] Based on the above description, the utility model provides a packaging device to solve the shortcomings of existing packaging equipment that can only be used for one production line, resulting in a large occupied area and limited production efficiency.

Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0024] Combination Figures 1-4 As shown, a packaging device comprises:

[0025] The silo 1 is a shell for storing food, with an opening at the top and a bucket-shaped lower half, and a protrusion formed at the center of the bottom surface. The two sides of the protrusion are respectively provided with feeding pipes 11, so as to realize synchronous feeding of two production lines;

[0026] The guide shaft 2 is vertically arranged inside the protruding part, and is mainly used to assist in conveying the food inside the silo 1 and simultaneously play a role in dredging;

[0027] The conveyor belt 5 is arranged just below the end of the conveying pipe 11 and is used to convey the packaged bags.

[0028] A feeding tray 3 is arranged on one side of the conveyor belt 5 and is used to cooperate with the feeding pipe 11 to transport the packaging bags;

[0029] The clamping assembly 4 is arranged on the feeding tray 3 and is used to fix, pack and seal the packing bags.

[0030] Specifically, spiral blades are arranged around the outer wall of the guide shaft 2, and the guide shaft 2 is fixedly connected to the inner wall of the silo 1 at its top end by a fixing frame, while the bottom end extends vertically downward and is finally movably connected to the bottom surface of the protrusion. A drive motor 12 is provided at the center of the bottom surface of the protrusion, and the output shaft of the drive motor 12 is vertically arranged upward and transmission-connected to the end of the guide shaft 2 to provide power for the guide shaft 2.

[0031] The feeding tray 3 is disc-shaped, and a fixing base is provided at its bottom. The fixing base is a split structure, consisting of an upper part and a lower part. The lower part is fixedly connected to the ground, and the upper part is movably connected to the lower part by a bearing unit. Moreover, in this structure, an electric motor is provided at the center of the top surface of the lower part, mainly used to drive the upper part to rotate.

[0032] The upper half of the top surface edge of the fixing base 31 is surrounded by a plurality of sliding sleeve rods 32. The sliding sleeve rod 32 is composed of two mutually sleeved metal rods, and a movable cylinder 33 is provided at the center of the top surface of the upper half of the fixing base 31. The top end of the movable cylinder 33 is fixedly connected to the center of the bottom surface of the feeding tray 3, so that the entire feeding tray 3 can be driven to perform short-distance lifting adjustment.

[0033] On the feeding tray 3, at least 4 workstations are arranged at its edge respectively. A set of clamping components 4 are arranged on each workstation, and the 4 workstations are arranged in a circular array, and always make one of the workstations exactly located directly below the end of the feeding pipe 11.

[0034] The clamping component 4 is composed of a pneumatic gripper 41, a chute 42 and a bag sealing plate 43:

[0035] Among them, two chutes 42 are arranged on both sides of the top surface of the workstation. A lead screw 44 is rotatably installed inside one of the chutes 42. Two opposite threaded sections are formed on the lead screw 44 extending from the center to both ends. And two bag sealing plates 43 are also arranged horizontally in the chute 42. The two bag sealing plates 43 are respectively arranged on two different threaded sections, and heat sealing strips are provided on the opposite sides. One end of the lead screw 44 extends towards the inside of the feeding tray 3 and is equipped with a servo motor at its end, so as to drive the two bag sealing plates 43 to close or unfold by rotating;

[0036] Two pneumatic grippers 41 are also arranged on the inner side walls of the workstation opposite to each other. At the same time, an electric telescopic rod 45 is provided at the end of the pneumatic gripper 41. The main body part of the electric telescopic rod 45 is placed inside the feeding tray 3. Therefore, the two pneumatic grippers 41 can be driven by the electric telescopic rod 45 to squeeze towards the center, forcing an opening to be formed on the top surface of the packaging bag, and the opening can exactly cover the feeding pipe 11 completely. After the feeding is completed, when the electric telescopic rod 45 contracts, the top of the packaging bag can be flattened again, so that the bag sealing plate 43 can perform heat sealing treatment;

[0037] Therefore, with the above structures cooperating with each other, the packaging bag can be quickly sealed after packing the food, and placed on the conveyor belt 5 for transfer, greatly improving the production efficiency of the equipment.

[0038] In this embodiment, the feeding tray 3 is first pre-loaded with packaging bags through external equipment, and the two sides of the packaging bags are fixed by pneumatic clamps 41, and then the top of the packaging bags is made to exceed the height of the bag sealing plate 43, and then it is rotated to the next station, and the electric telescopic rod 45 pushes the pneumatic clamp 41 to squeeze inward, so that a circular opening is opened in the center of the packaging bag, and it continues to rotate to the next station. At this time, the opening of the packaging bag is just arranged below the feeding pipe 11, and the movable cylinder 33 is lifted upward and the two are close to each other, and then the driving motor 12 starts to work and uses the spiral blade to discharge the material at a uniform speed. After filling, the movable cylinder 33 shrinks, and the electric telescopic rod 45 flattens the packaging bag on both sides, and the two bag sealing plates 43 are close to each other and use high temperature to quickly heat-seal the bag opening. After heat sealing is completed, the bag sealing plate 43 is away from the packaging bag, and the pneumatic clamp 41 is released synchronously, and the packaged snacks fall directly onto the conveyor belt 5 for transportation and packaging.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the technical solution of the embodiments of the utility model.
