Description

Technical Field

[0001] The utility model relates to a vacuum machine, and more specifically to a bag - feeding vacuum machine. Background Art

[0002] The bag - feeding food packaging machine is a packaging device that can automatically output packaging bags, open the bag mouths of the packaging bags, inject food, and automatically seal the bag mouths. The rotary - table bag - feeding packaging machine has a rotatable turntable, and a number of clamping claws connected to the turntable are evenly distributed on the edge of the turntable. A bag - feeding mechanism, a bag - opening mechanism, and a filling mechanism that can cooperate with the clamping claws thereon are provided at the edge of the turntable. When the turntable rotates through a driving member, the clamping claws thereon can transfer the packaging bags in the bag - feeding mechanism to the bag - opening mechanism for bag - opening as the turntable rotates, and then transfer the bag - opened packaging bags to the filling mechanism for filling.

[0003] The applicant applied for a full - automatic rotary - table bag - feeding vacuum packaging machine on July 21, 2016, with the application number: CN201610585669.0. It realizes feeding, bag - opening, filling, and then transfers and sends them into the vacuum - pumping mechanism through the bag - feeding mechanism, bag - opening mechanism, filling mechanism, transfer mechanism, and vacuum - pumping mechanism. The vacuum - pumping mechanism is currently composed of a vacuum - pumping turntable and a number of vacuum - pumping mechanisms combined. The number of vacuum - pumping mechanisms is circumferentially distributed along the circumference of the vacuum - pumping turntable. Generally, the vacuum - pumping mechanism is composed of two splints that can be opened and closed. However, the vacuum - pumping mechanism is vertically vacuum - sealed, and there is an easy problem of the packaging bag slipping during the working process. Therefore, the applicant improved the vacuum - pumping mechanism on September 22, 2020, with the application number CN202011001706.1, named a rotary - table vacuum - pumping device for food packaging equipment, which realizes vacuum - sealing by horizontally arranging upper and lower splints, thereby avoiding the problem of the packaging bag slipping easily. Currently, in order to ensure the opening and closing efficiency and save costs, generally a roller is provided at the lower splint, and then a cam guide edge is provided at the position of the roller close to the discharge port. The cooperation between the roller and the cam guide edge is used to drive the lower splint to flip down and open or flip up and close. However, after the lower splint flips down and opens for discharging, due to the relatively high self - weight of the lower splint itself and the weight of the material, there is generally a situation where it is not easy for the lower splint to flip up and close in place.

[0017] The following will further elaborate on the present utility model in combination with the embodiments given in the drawings.

[0018] Refer to Figures 1 to 4As shown in the figure, a bag-feeding vacuum machine according to this embodiment includes a frame 9, and a bag-feeding device 1, a bag-opening device 2, a filling device 3, and a vacuum-pumping device 4 that are all arranged on the frame 9. The vacuum-pumping device 4 includes a vacuum-pumping turntable 41 and a plurality of vacuum-pumping clamping plates 42. The plurality of vacuum-pumping clamping plates 42 are installed on the circumference of the vacuum-pumping turntable 41 and are distributed in a circular pattern along the circumference of the vacuum-pumping turntable 41. The vacuum-pumping clamping plate 42 includes an upper clamping plate 421 and a lower clamping plate 422. The upper clamping plate 421 is installed on the circumference of the vacuum-pumping turntable 41. One side of the lower clamping plate 422 is hingedly installed on the circumference of the vacuum-pumping turntable 41 and is located on the lower side of the upper clamping plate 421 to flip up and down below the upper clamping plate 421. An elastic component 5 is connected between the lower side of the lower clamping plate 422 and the circumference of the vacuum-pumping turntable 41 to accumulate elastic force when the lower clamping plate 422 flips downward and release the elastic force when the lower clamping plate 422 flips upward. During the process of using the bag-feeding vacuum machine of this embodiment, it is only necessary to put the packaging bag into the bag-feeding device 1 and then place the material into the filling device 3. By setting the vacuum-pumping device 4 as the vacuum-pumping turntable 41 and the vacuum-pumping clamping plates 42, the effect of vacuum packaging can be effectively achieved. During the vacuum packaging process, it is mainly through the up-and-down flipping of the lower clamping plate 422 to continuously receive the packaging bags filled with materials, evacuate the air, and then package them. By setting the elastic component 5, the elastic force can be effectively accumulated when the lower clamping plate 422 flips downward and released when the lower clamping plate 422 flips upward, so as to effectively ensure that the lower clamping plate 422 can flip upward in place.

[0019] As a specific improvement embodiment, the elastic component 5 is an air spring. One end of the air spring is hingedly installed at a position on the lower side of the lower clamping plate 422 away from its hinge axis, and the other end is hingedly installed on the lower side of the circumference of the vacuum-pumping turntable 41. By using the air spring as the elastic component 5, it can better achieve the accumulation and release of elastic force, and under high-frequency use, a series of problems caused by the lack of elastic force of the elastic component due to material fatigue will not occur quickly.

[0020] As an improved specific implementation method, a mounting column 6 is coaxially fixed at the center of the upper side of the vacuum turntable 41, and a plurality of connecting rods 7 are hinged on the outer side wall of the mounting column 6. The ends of the plurality of connecting rods 7 are hinged to the upper side of the upper clamping plate 421 respectively corresponding to each other, and an arc-shaped connecting rod 71 is hinged at a position close to the end of the connecting rod 7. The upper end of the arc-shaped connecting rod 71 is hinged to the connecting rod 7, and the lower end is hinged to the side of the lower clamping plate 422. By setting the mounting column 6 and the connecting rod 7, the upper clamping plate 421 and the lower clamping plate 422 can be effectively installed separately. This allows a larger opening and closing space to be created between the lower clamp 422 and the upper clamp 421 when it is flipped up and down. At the same time, through the arrangement of the arc-shaped connecting rod 71, the upper clamp 421 can be driven upward to open during the downward flipping of the lower clamp 422, and vice versa, the upper clamp 421 can be driven downward to close during the upward flipping of the lower clamp 422. In this way, the cooperation between the upper clamp 421 and the lower clamp 422 allows a larger opening space to be created when receiving a packaging bag filled with materials, and sufficient sealing is ensured between the upper clamp 421 and the lower clamp 422 during the vacuum sealing process.

[0021] As a specific implementation of the improvement, a support ring 8 is coaxially fixed to the lower side of the vacuum turntable 41, and the frame 9 is provided with a support component 91 for resisting the support ring 8 below the support ring 8. Through the arrangement of the support ring 8 and the support component 91, the support component 91 can be effectively used to support the support ring 8 to achieve the supporting effect on the vacuum turntable 41, so that the operation of the vacuum turntable 41 is more stable and reliable.

[0022] As an improved specific embodiment, the support component 91 includes a support column 911 and a roller 912. The lower end of the support column 911 is fixedly mounted on the frame 9, and the roller 912 is rotatably mounted on the upper end of the support column 911 and abuts against the lower end surface of the support ring 8 to support the support ring 8. Through the arrangement of the support column 911 and the roller 912, the support effect can be effectively achieved by utilizing the function of the support column 911, and through the function of the roller 912, the support effect can be effectively achieved by abutting the wheel surface of the roller 912 against the end surface of the support ring 8, and it can roll with the rotation of the support ring 8.

[0023] As an improved specific implementation method, the support column 911 includes a column sleeve 9111 and a column rod 9112. The lower end of the column rod 9112 is fixed on the frame 9. The lower end of the column sleeve 9111 can be raised and lowered on the column rod 9112. The roller 912 can be rotatably set on the upper end of the column sleeve 9111. Through the setting of the column sleeve 9111 and the column rod 9112, a support column 911 structure that can be extended and retracted up and down can be effectively formed.

[0024] As a specific implementation of the improvement, an adjusting handwheel 9113 is coaxially and rotatably provided at the lower end of the column sleeve 9111. Threads are provided on the outer sidewall of the column rod 9112, and a threaded hole is provided at the lower end of the adjusting handwheel 9113. The adjusting handwheel 9113 is sleeved on the column rod 9112 such that the threaded hole is threadedly connected to the threads. Through the setting of the adjusting handwheel 9113, the threaded hole can be effectively made to cooperate with the threads by rotating the adjusting handwheel 9113, thereby achieving the effect of adjusting the length of the support column 911.

[0025] In summary, for the bag-feeding vacuum machine of this embodiment, through the setting of the elastic component 5, it can be effectively realized that during the downward flipping of the lower clamping plate 422, the elastic force is accumulated by the elastic component 5, and during the upward flipping of the lower clamping plate 422, the elastic force is released by the elastic component 5 to drive the lower clamping plate 422 to flip upward in place, thereby achieving the effect of good heat sealing.

[0026] The above are only the preferred implementation manners of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the concept of the present invention belong to the protection scope of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, several improvements and refinements made without departing from the principle of the present invention should also be regarded as within the protection scope of the present invention.
