Description

TECHNICAL FIELD

[0001] The utility model relates to the field of clamp forming, in particular to a clamp packing equipment. BACKGROUND

[0002] The elastic clamp is a common pipe connecting fastener, in order to keep good connection strength, the elastic clamp needs larger force to open, so as to facilitate installation, the elastic clamp needs to be fixed with the two ear parts of the elastic clamp after forming in the production process, so that the elastic clamp keeps the open state, and the installation of the elastic clamp can be quickly completed by removing the buckle.

[0003] The clamp needs to be packaged with a packaging bag after forming, and in order to reduce the packaging cost and facilitate sales, a certain number of clamps are usually put into the same packaging bag for packaging. Directly making the clamp fall from the conveying belt into the packaging bag will cause the clamp to fall outside the packaging bag due to the distance between the packaging bag and the conveying belt.

[0004] At present, there is a kind of pneumatic sealing and cutting machine as shown in patent No. CN217295127U, which comprises a machine body and a heat sealing mechanism arranged on the machine body. The machine body is provided with a material guiding mechanism for guiding the product into the packaging film. The material guiding mechanism comprises a mounting frame, a material guiding cylinder and a material guiding hopper. The mounting frame is fixedly connected to the machine body. The material guiding cylinder is vertically fixedly connected to the lower side of the mounting frame. The material guiding hopper is arranged below the material guiding cylinder and communicates with the material guiding cylinder. The outlet of the material guiding hopper can be aligned with the bag opening of the blown packaging film. The material guiding hopper is slidably connected with the material guiding cylinder and can slide in the vertical direction. A feeding cylinder is fixedly connected to the mounting frame and can control the upward and downward sliding of the material guiding hopper.

[0005] The above sealing and cutting machine can insert the material guiding hopper into the packaging bag by sliding downward during work, and guide the workpiece to be packaged to prevent the workpiece from falling outside the packaging bag. However, when the above device is applied to clamp packaging, since the material guiding cylinder and the material guiding hopper still have a relatively large distance from the packaging bag, the clamp has edges and corners, and the packaging bag made of plastic material can be easily damaged when the clamp falls from a higher position into the packaging bag. Moreover, a plurality of clamps need to be put into each packaging bag, so the adjacent clamps are likely to collide when falling into the packaging bag, thereby causing the buckles on the clamps to fall off. Finally, the number of clamps in each packaging bag needs to be the same, and the clamps need a certain time for forming and detection. Therefore, there is a certain distance between the adjacent clamps on the conveying belt, and the packaging bag needs to be kept in an open state for a relatively long time to ensure that the specified number of clamps fall into the packaging bag. After the clamps in one packaging bag are packed, the packaging bag containing the clamps needs to be sealed, and the next packaging bag needs to be moved to the lower side of the material guiding cylinder and opened, which reduces the packaging efficiency.

[0038] The supporting assembly comprises a supporting plate 6, a discharging element 23 and a connecting rod 61. The supporting plate 6 is V-shaped and is arranged directly below the material guiding cylinder 12. Specifically, the supporting plate 6 in the embodiment is lower than the sealing assembly and the clamping assembly and is used for supporting the packaging bag falling into the clamping block. The middle part of the connecting rod 61 is hingedly connected with the adjusting frame 2, the left end is welded with the right side wall of the supporting plate 6, and the right end is axially provided with a strip-shaped groove. A rotating shaft 62 is slidably connected in the strip-shaped groove. The discharging element 23 also adopts a linear actuator. The push rod of the discharging element 23 faces downward, and the rotating shaft 62 transversely penetrates the push rod of the discharging element 23, so that the push rod of the discharging element 23 can push the connecting rod 61 to counterclockwise swing when the push rod slides upward.

[0039] The specific implementation process is as follows:

[0040] The formed clamping block is driven by the conveying belt to the upper part of the hopper 1, falls from the conveying belt to the inclined surface 15, and then slides downward to the bottom of the hopper 1 and is limited by the sealing plate to stay in the hopper 1. At the same time, the transverse driving element 52 drives the clamp 51 to slide to the left, clamps the mouth of the packaging bag through the clamp 51, and then drives the clamp 51 to reset to the right, clamps the mouth of the packaging bag between the two sealing assemblies. Finally, the sealing element 41 is started, the suction cups 42 of the two sealing assemblies abut against the mouth of the packaging bag, negative pressure is formed in the suction cups 42 through the air pipe, the left and right side walls of the packaging bag are adsorbed, and then the sealing element 41 resets the mounting seat 4 to open the opening of the packaging bag.

[0041] When the number of clamping blocks in the material guiding cylinder 12 reaches the requirement, the material guiding cylinder 12 is inserted into the packaging bag downward through the vertical pushing element 11, the sealing plate slides out of the hopper 1, the hopper 1 is opened, and the clamping block falls into the packaging bag downward. When the clamping block is completely fallen out, the sealing plate is slid into the hopper 1 again, the material guiding cylinder 12 is sealed, and the material guiding cylinder 12 is reset upward to be separated from the packaging bag.

[0042] Then the heating element 43 is started, and the mounting seat 4 is slid to the direction of approaching each other through the sealing element 41 until the two heating elements 43 abut, and the packaging bag is heat sealed, and since the mouth of the packaging bag is adsorbed on the suction cup 42 at this time, the mouth of the packaging bag is completely unfolded, and the packaging bag can be heat sealed more flatly.

[0043] After the heat sealing is completed, air is supplied to the suction cup 42 through the air pipe, so that the suction cup 42 no longer adsorbs the packaging bag, and at the same time, the heating element 43 is closed, and the mounting seat 4 is reset to the direction of moving away from each other, so that the packaging bag is no longer fixed by the sealing assembly. When the clamp falls into the packaging bag, the bottom of the packaging bag falls on the supporting plate 6, and the clamp is protected and supported by the supporting plate 6, so that the packaging bag is prevented from being damaged by bearing too much weight. When the packaging bag is heat sealed and the mounting seat 4 is reset to the direction of moving away from each other, the push rod of the discharging element 23 is slid upward, the connecting rod 61 is rotated clockwise, the supporting plate 6 is inclined, and the packaging bag containing the clamp is automatically dropped on the supporting plate 6. In actual implementation, a conveying belt is arranged below the supporting plate 6, so that the packaged packaging bag can be conveyed to the next process or warehouse.

[0044] When a packaging bag with a larger size needs to be used for packaging, the handle 31 is rotated, the screw rod 21 is rotated, and the adjusting frame 2 is slid downward, so that the distance between the supporting plate 6 and the material guiding cylinder 12 is increased; similarly, when a packaging bag with a smaller size needs to be used for packaging, the adjusting frame 2 is slid upward, so that the distance between the supporting plate 6 and the material guiding cylinder 12 is reduced, so that the supporting plate 6 can abut against the bottom of the packaging bag when the clamp falls into the packaging bag, and the packaging bag is supported.

[0045] The above is only an embodiment of the present application, and the specific technical solutions and / or common knowledge of the scheme are not described in detail. It should be noted that for those skilled in the art, without departing from the technical solutions of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application.
