Description

Technical Field

[0001] The utility model relates to the technical field of packaging bag clamps, in particular to a bag opening clamp for packaging. Background Art

[0002] Automatic packaging machines are devices used to automatically load products into packaging materials. These machines are commonly used for packaging food, pharmaceuticals, cosmetics, and other consumer goods. They can be customized based on the product's characteristics and needs, and can automatically perform tasks such as weighing, filling, sealing, and labeling, improving production efficiency and ensuring packaging consistency and hygiene. During the packaging process, the bag needs to be fixed, supported, and protected, so a bag clamp is used to achieve this.

[0003] However, in the existing packaging bag opening clamps, the clamps usually only clamp the two sides of the packaging bag and open the bag opening by lateral squeezing. However, since the opening area of ​​the bag opening of some packaging bags is relatively small, the packaging machine is likely to cause the material to scatter outside when unloading, which reduces the packaging quality and affects the working quality of the packaging bag opening clamp. Therefore, we propose a packaging bag opening clamp. Utility Model Content

[0004] The purpose of the present utility model is to provide a bag opening clamp for packaging to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a bag mouth clamp for packaging, comprising a base and a clamping mechanism, one side of the base is movably connected to a connecting plate through a rotating seat, a No. 1 electric push rod is connected between the base and the connecting plate through a movable shaft, and the clamping mechanism is connected to the side of the connecting plate away from the rotating seat.

[0006] Preferably, a lifting mechanism is provided in the middle of the base, one side of the lifting mechanism is connected to a No. 1 electric telescopic rod, and a pull rod is fixed to the end of the No. 1 electric telescopic rod away from the lifting mechanism.

[0016] The utility model proposes a bag opening clamp for packaging. After the clamping mechanism clamps the packaging bag, the roller is pushed to one side by the No. 2 electric telescopic rod. The roller rolls on the inclined surface of the trapezoidal block, and the roller squeezes the trapezoidal block downward. The two ends of the trapezoidal block slide downward on the sliding rod and squeeze the supporting spring. Then the trapezoidal block causes the No. 1 electric telescopic rod to drive the pull rod to move downward, and the No. 1 electric telescopic rod then drives the pull rod to move to one side, so that the pull rod opens one side of the bag opening of the packaging bag.

All other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1, please refer to Figures 1 to 4 The utility model provides a technical solution: a bag opening clamp for packaging, comprising a base 1 and a clamping mechanism 5, one side of the base 1 is movably connected to a connecting plate 4 through a rotating base 2, a No. 1 electric push rod 3 is connected between the base 1 and the connecting plate 4 through a movable shaft, the clamping mechanism 5 is connected to the side of the connecting plate 4 away from the rotating base 2, the clamping mechanism 5 comprises a No. 2 electric push rod 501, a support rod 502, a No. 1 clamping plate 503, a No. 2 clamping plate 504 and a guide rod 505, the A support rod 502 is fixed to one side of the connecting plate 4, and a No. 2 splint 504 is fixed to the end of the support rod 502 away from the connecting plate 4, and a No. 2 electric push rod 501 is fixed to the side of the No. 2 splint 504 close to the support rod 502, and a No. 1 splint 503 is fixed to the end of the No. 2 electric push rod 501 close to the No. 2 splint 504, and a guide rod 505 is provided on the side of the No. 1 splint 503 close to the No. 2 splint 504, and the guide rod 505 and the No. 2 splint 504 are slidably connected.

[0026] During the specific implementation, the base 1 is first installed on the packaging machine by bolts, and then the two sides of the bag opening of the packaging bag are placed between the No. 1 plywood 503 and the No. 2 plywood 504, and then the No. 2 electric push rod 501 is extended and retracted to make the No. 1 plywood 503 and the No. 2 plywood 504 clamp the two ends of the packaging bag, and at the same time the guide rod 505 guides the No. 1 plywood 503, and then the No. 1 electric push rod 3 pushes the connecting plate 4 to one side, and the connecting plate 4 rotates to one side by a certain angle through the rotating seat 2. The lateral extrusion of the No. 1 plywood 503 and the No. 2 plywood 504 can open the bag opening for packaging work.

[0027] Example 2, please refer to Figures 1 to 4 On the basis of embodiment 1, a lifting mechanism 7 is provided in the middle of the base 1, and one side of the lifting mechanism 7 is connected to the No. 1 electric telescopic rod 6. The end of the No. 1 electric telescopic rod 6 away from the lifting mechanism 7 is fixed with a pull rod 8. The lifting mechanism 7 includes a supporting spring 701, a trapezoidal block 702, a roller 703, a No. 2 electric telescopic rod 704 and a sliding rod 705. The trapezoidal block 702 is slidably connected in the built-in groove in the middle of the base 1, and the sliding rod 705 is installed on the inner wall of the base 1 near both sides of the trapezoidal block 702. The outer side of the sliding rod 705 is sleeved with a supporting spring 701, and the sliding rod 705 is slidably sleeved with the two ends of the trapezoidal block 702. The base 1 is installed with a No. 2 electric telescopic rod 704 above the trapezoidal block 702 by bolts, and the end of the No. 2 electric telescopic rod 704 near the trapezoidal block 702 is installed with a roller 703 through a movable shaft.

[0028] During specific implementation, since the open area of ​​the bag opening of some packaging bags is relatively small, it is inconvenient to carry out packaging work. After the packaging bag is clamped by the clamping mechanism 5, the roller 703 can be pushed to one side by the No. 2 electric telescopic rod 704. The roller 703 rolls on the inclined surface of the trapezoidal block 702, and the roller 703 squeezes the trapezoidal block 702 downward. The two ends of the trapezoidal block 702 slide downward on the slide rod 705 and squeeze the support spring 701. Then the trapezoidal block 702 causes the No. 1 electric telescopic rod 6 to drive the pull rod 8 to move downward, and the No. 1 electric telescopic rod 6 then drives the pull rod 8 to move to one side, so that the pull rod 8 pulls open one side of the bag opening of the packaging bag, which can prevent the bag opening from being too small in area and affecting the packaging work, thereby improving the working quality of the bag opening clamp for packaging.

[0029] Example 3, please refer to Figures 1 to 2 and Figures 4 to 6On the basis of Example 2, a fixing rod 11 is fixed to the side of the base 1 close to the clamping mechanism 5, and a collection box 10 is provided on one side of the fixing rod 11. A limiting mechanism 9 is provided on the side of the collecting box 10 close to the fixing rod 11, and one side of the limiting mechanism 9 is connected to the fixing rod 11. The limiting mechanism 9 includes a through hole 901, a limiting block 902, a limiting spring 903 and an insertion rod 904. One end of the collecting box 10 close to the fixing rod 11 is connected to the insertion rod 904, and a limiting spring 903 is provided in the built-in groove of the insertion rod 904. A limiting block 902 is provided on one side of the limiting spring 903. A through hole 901 is provided on the side of the fixing rod 11 close to the limiting block 902, and a jack is provided on the side of the fixing rod 11 close to the insertion rod 904.

[0030] During specific implementation, some packaging bags may be damaged due to processing reasons. The materials in the damaged packaging bags are easy to fall onto the packaging machine, which is not convenient for subsequent cleaning. The collection box 10 can be installed on the base 1 of the packaging bag mouth clamp. First, the insertion rod 904 is inserted into the socket of the fixed rod 11, and then the limit spring 903 rebounds to drive the limit block 902 to be stuck in the through hole 901, which limits the position of the insertion rod 904. The collection box 10 can be quickly installed, which is convenient for collecting the materials spilled in the damaged packaging bags and facilitating subsequent cleaning, thereby improving the working quality and practicality of the packaging bag mouth clamp.

[0031] In actual use, the base 1 is first installed on the packaging machine by bolts, and then the packaging bag is manually placed on the inner side of the clamping mechanism 5, and the packaging bag is clamped by the clamping mechanism 5. At the same time, the lifting mechanism 7 is used to assist in opening the bag mouth of the packaging bag, which is convenient for the packaging machine to unload and package. During the packaging process, the collection box 10 collects the spilled materials, and the collection box 10 can be installed and disassembled through the limiting mechanism 9, which is convenient for subsequent cleaning. The lifting mechanism 7 and the limiting mechanism 9 improve the bag mouth clamp for packaging.
