Description

Technical Field

[0001] This utility model relates to the field of packaging machine technology, specifically to a packaging bag clamping device in a packaging machine. Background Technology

[0002] In packaging machines, products are packaged in bags. When transporting or transferring the packaged products, the bags are held in place by a clamping device. The clamping device uses a finger cylinder to control two clamps to hold the bags tightly. However, with this clamping method, the bags can easily fall off between the clamps. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a packaging bag clamping device in a packaging machine, which addresses the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A packaging bag clamping device in a packaging machine includes a finger cylinder. The finger ends of the finger cylinder are respectively equipped with a clamping head one and a clamping head two. Clamping plates are symmetrically installed on both sides of the clamping head one and the clamping head two. A pin is provided between the clamping plates. When the clamping plates clamp the packaging bag, the clamping surfaces of the pin and the clamping plates are offset.

[0006] Furthermore, mounting heads are machined on both sides of the first and second chucks, and mounting holes are machined on the mounting heads. The mounting holes are connected to the finger tip of the finger cylinder by screws.

[0007] Furthermore, the first chuck has an outwardly protruding mounting block machined in the middle, and a threaded hole machined on the mounting block. One end of the pin has a threaded head, and the threaded head of the pin connects with the threaded hole on the mounting block. The second chuck has an inner groove machined in the middle. When the first chuck and the second chuck are closed, the mounting block is inserted into the inner groove.

[0008] Furthermore, the end face of the mounting block is chamfered.

[0009] Furthermore, the clamping surface of the clamping plate is machined with knurled patterns.

[0010] Compared with the prior art, the packaging bag clamping device in the packaging machine of this utility model has a pin that lifts up the packaging bag when the clamping head clamps the packaging bag, so that the clamping plates on both sides of the pin are misaligned to clamp the packaging bag. By setting the pin, the packaging bag is tightened when the clamping plates clamp it, thus preventing the packaging bag from falling off. Attached Figure Description

[0015] The technical solutions in the embodiments of this utility model will be clearly and completely described below.

[0016] like Figure 1 and Figure 2 As shown, a packaging bag clamping device in a packaging machine includes a finger cylinder 1. The finger ends of the finger cylinder 1 are respectively equipped with a first clamp 2 and a second clamp 3. Mounting heads 4 are machined on both sides of the first clamp 2 and the second clamp 3. Mounting holes are machined on the mounting heads 4, and the mounting holes are fixedly connected to the finger ends of the finger cylinder 1 by screws. Clamping plates 5 are symmetrically installed on both sides of the first clamp 2 and the second clamp 3. To increase the surface friction during clamping, knurling is machined on the clamping surfaces of the clamping plates 5. A pin 6 is provided between the clamping plates 5. When the clamping plates 5 clamp the packaging bag, the pin 6 is offset from the clamping surfaces of the clamping plates 5.

[0017] In this embodiment, as Figure 3 As shown, the first chuck 2 has an outwardly protruding mounting block 7 machined in the middle, and a threaded hole is machined on the mounting block 7. One end of the pin 6 is machined with a threaded head, and the threaded head of the pin 6 connects with the threaded hole on the mounting block 7. The second chuck 2 has an inner groove 8 machined in the middle. When the first chuck 1 and the second chuck 2 are closed, the mounting block is inserted into the inner groove. In order to facilitate insertion into the inner groove, the end face of the mounting block 7 is chamfered. When clamping the packaging bag, the pin 6 pushes the packaging bag to the side to form a staggered clamping, which provides tension force for the clamping plate 5 to clamp, tightens the packaging bag, and prevents the packaging bag from slipping out between the clamping plates 5.

[0018] This utility model is not limited to the embodiments described. Those skilled in the art can still make some modifications or changes without departing from the spirit and scope of this utility model. Therefore, the scope of protection of this utility model shall be determined by the scope defined in the claims.
