Technical Field

[0001] The utility model relates to the technical field of packaging machine equipment, in particular to a bag-mouth material clamping detection device for a bag-feeding packaging machine. Background Art

[0002] The packaged products on the market now, such as candies, marinated snacks, nut snacks, etc., are packed in a large bag with different numbers of small bags or different flavors of snacks, which are convenient for consumption. Since the small bags are relatively bulging, after being loaded into the large bag, sometimes the inner bag will inevitably reach the seal of the outer bag of the large bag, causing material clamping at the seal, poor outer sealing, waste of packaging materials, and waste of packaging materials. In order to reduce this waste, the packaging speed can only be reduced and auxiliary devices can be added, which will greatly reduce the output of the equipment. This requires the design of a detection device with a simple structure, low cost, wide application, and the ability to accurately detect material clamping at the bag mouth. Through bag mouth detection, the clamped package is output to the packaging machine without sealing or is rejected before sealing. There is no need to add cumbersome auxiliary functions, which improves production efficiency while reducing the waste of packaging bags and saving production costs. Utility Model Content

DETAILED DESCRIPTION

[0018] like Figure 1-Figure 4As shown, a bag mouth clamping detection device for a bag-feeding packaging machine comprises a U-shaped support frame 1, a support arm 17 connected to the packaging machine is arranged on the U-shaped support frame 1, a driving shaft 2 and a driven shaft 3 passing through the U-shaped support frame 1 are arranged in the U-shaped support frame 1, the axes of the driving shaft 2 and the driven shaft 3 are on the same horizontal line, the driving shaft 2 and the driven shaft 3 are connected through a transmission mechanism, the driving shaft 2 and the driven shaft 3 are respectively connected with a driving arm 4 and a driven arm 5 for clamping the bag mouth, a distance measuring mechanism for detecting the distance between the two is arranged on the driving arm 4 and the driven arm 5, the driving shaft 2 is connected with a driving rocker 6, a driving cylinder 7 is arranged in the U-shaped support frame 1, the output end of the driving cylinder 7 is hinged with the driving rocker 6 through a rotating shaft 8, a cylinder fixing seat 16 is hinged at the tail of the driving cylinder 7, and the cylinder fixing seat 16 is connected to the U-shaped support frame 1.

[0019] The transmission mechanism includes a first connecting rocker 9 arranged at the end of the driving shaft 2 and the outside of the U-shaped support frame 1, and also includes a second connecting rocker 10 arranged at the end of the driven shaft 3 and the outside of the U-shaped support frame 1. The first connecting rocker 9 and the second connecting rocker 10 are connected by an inner thread joint bearing 11 and an outer thread joint bearing 12.

[0020] The distance measuring mechanism includes an outer clamping plate 13 and an inner clamping plate 14 arranged on the inner side of the bottom end of the driving arm 4 and the driven arm 5. A distance detector 15 for detecting the distance between the outer clamping plate 13 or the inner clamping plate 14 is provided. After the outer clamping plate 13 and the inner clamping plate 14 are bonded together, the bonding surface is flat and has no bevel.

[0021] The driving arm 4 is tightly connected to the driving shaft 2 through bolts, and the driven arm 5 is tightly connected to the driven shaft 3 through bolts.

[0022] Both ends of the driving shaft 2 and the driven shaft 3 are connected to the U-shaped support frame 1 through the center-adjusting bearing 18 with a seat, and the center-adjusting bearing 18 with a seat is connected to the U-shaped support frame 1 through bolts.

[0023] When in use, the driving cylinder 7 controls the rotation of the driving shaft 2 by driving the rocker 6, and the connecting rod composed of the first connecting rocker 9, the second connecting rocker 10 and the inner thread joint bearing 11 and the outer thread joint bearing 12 at the two shaft ends, so that the driven shaft 3 rotates together, and the driving arm 4 and the driven arm 5 are tightly held on the driving shaft 2 and the driven shaft 3, so that the driving arm 4 and the driven arm 5 can rotate inward and outward around the axis, and finally realize the closing and opening of the inner splint 14 and the outer splint 13. The inner splint 14 and the outer splint 13 are completely closed, and the distance detector value is set to 0. When the two splints are normally clamped to the bag mouth of the packaging bag, due to the packaging The bag has thickness, and the two plywood cannot fit completely together. The distance detector will display the thickness of the packaging bag. At this time, we can set the thickness of the packaging bag to a critical value. When the material is clamped at the bag mouth, the distance between the plywood must be greater than the thickness of the packaging bag. At this time, the distance detector 15 will compare the set critical value with the actual value to determine whether the bag mouth is clamped with material, and output a signal to the packaging machine for processing, thereby realizing the detection of material clamping at the bag mouth. The entire device is simple to set up and has high detection accuracy. It can detect a distance difference of 0.002mm, solve the problems of low bag mouth detection accuracy and sealing clamping, and improve production efficiency.
