Description

Technical Field

[0001] The utility model relates to a component on a bag feeding machine, in particular to a vacuum pumping component of a vacuum packaging machine. Background Art

[0002] The bag feeding machine is a packaging equipment used to package food and other materials. After the food is put into the bag, it will be vacuumed to extend the shelf life of the food. When vacuuming, the bag mouth is generally pressed into a sealed cavity, and the cavity is connected to the vacuum pump through a pipeline. After the vacuum pump is started, the cavity is then vacuumed. The bag mouth of the packaging bag is sometimes automatically sucked together under the vacuum condition, resulting in the air in the packaging bag cannot be completely drained, which can easily lead to the failure of vacuuming. Utility Model Content

[0003] In order to solve the above problems, the purpose of the utility model is to provide a vacuum packing machine vacuum pumping component with reasonable design and reliable structure, so as to avoid the vacuum pumping failure.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a vacuum pumping component of a vacuum packaging machine, comprising a mounting plate, a telescopic cylinder is mounted on the upper end of the mounting plate, a piston rod of the telescopic cylinder is connected to a lifting seat, a vacuum pumping tube is mounted on the lifting seat, a finger cylinder is mounted on the side of the mounting plate, two telescopic fingers of the finger cylinder are respectively connected to a clamping plate, and foam pads are respectively connected to the inner side walls of the two clamping plates, the vacuum pumping tube comprises a connecting circular tube at the upper end and a plate-shaped tube at the lower end, the plate-shaped tube and the inner holes of the connecting circular tube are communicated, the plate-shaped tube extends into or out of the interval between the clamping plates through the telescopic cylinder, the connecting circular tube is connected to the vacuum pump through an electromagnetic valve, and the telescopic cylinder and the finger cylinder are connected to the air pump through their respective electromagnetic valves.

[0005] The transverse bisector of the plate-shaped tube is aligned with the clamping line of the two clamping plates.

[0006] A tubular connecting seat is installed on the installation plate, a fixing seat is sleeved on the tubular connecting seat, and the telescopic cylinder is installed on the fixing seat.

[0007] The beneficial effect of the utility model is that when the bag feeding machine transfers the packaging bag with the bag opening opened to the interval between the two clamping plates, the vacuum tube moves down and is inserted into the packaging bag, and then the clamping plates clamp the bag opening, and the bubble film pad on the clamping plates will be depressed by the pressure of the plate-shaped tube on the vacuum tube, thereby tightly pressing the bag opening. In this state, the vacuum tube extracts the air in the packaging bag through the vacuum pump to complete the vacuum operation. The structural design is reasonable and reliable, thereby avoiding the situation of vacuum failure.

[0008] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The present utility model will be specifically described below through embodiments, which are only used for further illustration of the present utility model and cannot be construed as a limitation on the protection scope of the present utility model.

[0012] As Figure 1 、 Figure 2 shown, this embodiment discloses a vacuum pumping component of a vacuum packaging machine, which includes a mounting plate 1. A telescopic cylinder 2 is installed at the upper end of the mounting plate 1. The piston rod of the telescopic cylinder 2 is connected to a lifting seat 3. A vacuum pumping tube 4 is installed on the lifting seat 3. A finger cylinder 5 is erected beside the mounting plate 1. Each of the two telescopic fingers of the finger cylinder 5 is connected to a clamping plate 6. Foam pads (not shown in the figure) are respectively connected to the inner side walls of the two clamping plates 6. The vacuum pumping tube 4 includes a connecting circular tube 41 at the upper end and a plate-shaped tube 42 at the lower end. The inner holes of the plate-shaped tube 42 and the connecting circular tube 41 are communicated. The plate-shaped tube 42 extends into or withdraws from the interval between the clamping plates 6 through the telescopic cylinder 2. The connecting circular tube 41 is connected to a vacuum pump through an electromagnetic valve. The telescopic cylinder 2 and the finger cylinder 5 are connected to an air pump through their respective electromagnetic valves.

[0013] The horizontal bisector of the plate-shaped tube 42 is aligned with the clamping line of the two clamping plates 6. Such a structural design can make the foam pads on the clamping plates 6 receive more balanced forces when clamping the plate-shaped tube 42, so that after the foam pads are compressed and contracted, the bag mouth of the packaging bag can be clamped more tightly.

[0014] A tubular connecting seat 7 is installed on the mounting plate 1. A fixed seat 8 is sleeved on the tubular connecting seat 7. The telescopic cylinder 2 is installed on the fixed seat 8. The fixed seat 8 can achieve fine adjustment of the rotation position through the tubular connecting seat 7. Through adjustment, the telescopic stroke of the vacuum pumping tube 4 can be better aligned with the central position of the bag mouth of the packaging bag, improving the reliability of the vacuum pumping tube 4 inserted into the packaging bag.

[0015] Adopting the above technical solution, when the bag feeder transfers the packaging bag with the opened bag mouth to the interval between the two clamping plates 6, the vacuum pumping tube 4 moves downward and inserts into the packaging bag. Subsequently, the clamping plates 6 clamp the bag mouth, and the foam pads on the clamping plates 6 will be recessed under the pressure of the plate-shaped tube 42 on the vacuum pumping tube 4, thereby tightly clamping the bag mouth of the packaging bag. In this state, the vacuum pumping tube 4 pumps out the air in the packaging bag through an air extraction pump, completing the vacuum pumping operation. This structural design is reasonable and reliable, thus avoiding the situation of vacuum pumping failure.

[0016] The foregoing has shown and described the basic principles, main features and advantages of the present invention.
