The utility model relates to a bag clamping device on an automatic bag opening machine, which provides the bag clamping device suitable for the automatic bag opening machine. By using the automatic bag opening machine, the defects of the heavy labor intensity of the prior means of artificially opening bag and being unfavorable to the highly active line production can be overcome. The bag clamping device is provided with a mounting bracket of which both sides are respectively provided with a clamping arm and a first cylinder driving the clamping arm to swing back and forth, wherein, the clamping arm are respectively arranged at the left and the right sides, and provided with a clamping part at the lower part of the mounting bracket. A first clamping surface is positioned at the section close to the two clamping parts, and the clamping part of the two arm locks can achieve the clamping and opening in the process of the clamping arm swinging back and forth; a second cylinder is oppositely and respectively arranged on the clamping part of the two arm locks, and the two second cylinders are provided with protrusion ends extending in an opposite direction. A second clamping face is positioned at the section close to the two protrusion ends, and the second clamping face and the first clamping face are arranged side by side in a stagger mode.

Description

The bag clamping device of bag-opening machine

Technical field

The utility model relates to the bag clamping device on a kind of automatic bag-opening machine.

Background technology

At present, with bag package stock such as plastic pellet, flour, paddy etc. are opened bag, and raw material is inclined to the method for advancing former feed bin all is to adopt artificial method, obvious this method labour intensity is big, and be unfavorable for the high-efficiency stream operation, so, existing this class manufacturing enterprise all wishes to have a kind of machine that can open bag automatically to replace manual work, be necessary to be provided with a kind of bag clamping device as bag-opening machine, can when being in erectility, clamp by sack the top of sack, and can make a raw material in the bag can not clamped and all incline to going out, also be to realize that automatic bag-opening machine opens the technology crux of bag automatically so whether a kind of suitable bag clamping device can be provided.

Summary of the invention

The technical problems to be solved in the utility model is: a kind of bag clamping device that automatic bag-opening machine is used that is suitable for is provided, by the application to automatic bag-opening machine, overcomes the defective that the existing labour intensity of manually opening bag method is big, be unfavorable for efficient Detroit automation.

The technical scheme that its technical matters that solves the utility model adopts is: a kind of bag clamping device of bag-opening machine, it is characterized in that: have fixed mount, the both sides of fixed mount are respectively arranged with a jig arm and drive first cylinder of jig arm reciprocally swinging, the described jig arm that is provided with respectively is left and right sides arrangement states, jig arm has holding part in the bottom of fixed mount, two holding part are first to seize face on both sides by the arms mutually nearby, and the holding part of two jig arm realizes seizing on both sides by the arms and opening in the process of jig arm reciprocally swinging.

Specifically: the top of described fixed mount is cross tube, the bottom of fixed mount is a sheer pole, described jig arm is Z-shaped jig arm, the described jig arm that is provided with respectively is the left-right symmetric state, the fixed end pin joint of first cylinder of She Zhiing is in the end of cross tube respectively, the movable end pin joint of the upper extreme point of Z-shaped jig arm and first cylinder, the last flex point pin joint of Z-shaped jig arm is in the end of sheer pole.

For fear of the folder bag process bag interior article are remained in the bag, the utility model also is provided with at second fixing device of sack except that the position of the clamped position first time sentencing, promptly on the holding part of described two jig arm, also be relatively set with second cylinder respectively, two second cylinders have the external part that stretches out in opposite directions, two external parts are second to seize face on both sides by the arms mutually nearby, and described second seizes face on both sides by the arms and first face of seizing on both sides by the arms is being arranged side by side of staggering.

The beneficial effects of the utility model are, structure setting of the present utility model provides a kind of bag clamping device that automatic bag-opening machine is used that is suitable for, further by application, overcome the defective that the existing labour intensity of manually opening bag method is big, be unfavorable for efficient Detroit automation to automatic bag-opening machine.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the view of seizing on both sides by the arms of the present utility model.

Fig. 2 is an open mode scheme drawing of the present utility model.

1. fixed mounts among the figure, 2. jig arm, 3. first cylinder, 4. second cylinder, 11. cross tubes, 12. sheer poles, 21. holding parts, 22. first seize face on both sides by the arms, and 41. second seize face on both sides by the arms.

The specific embodiment

A kind of specific embodiment of the bag clamping device of the utility model bag-opening machine as shown in Figure 1, has fixed mount 1, the both sides of fixed mount 1 are respectively arranged with a jig arm 2 and drive first cylinder 3 of jig arm 2 reciprocally swingings, the jig arm 2 of She Zhiing is the left-right symmetric state respectively, jig arm 2 has holding part 21 in the bottom of fixed mount 1, two holding part 21 are first to seize face 22 on both sides by the arms mutually nearby, the holding part 21 of two jig arm 2 realizes seizing on both sides by the arms and opening in the process of jig arm 2 reciprocally swingings, as accompanying drawing 2.

The top of fixed mount 1 is cross tube 11 in the accompanying drawing 1, the bottom of fixed mount 1 is a sheer pole 12, jig arm 2 is Z-shaped, the fixed end pin joint of first cylinder 3 of She Zhiing is in the end of cross tube 11 respectively, the movable end pin joint of the upper extreme point of jig arm 2 and first cylinder 3, the last flex point pin joint of jig arm 2 is in the end of sheer pole 12.

Also be relatively set with 4, two second cylinders 4 of second cylinder respectively and have the external part that stretches out in opposite directions on the holding part 21 of two jig arm 2, two external parts are second to seize face 41, the second on both sides by the arms and seize face 41 and first on both sides by the arms to seize face 22 on both sides by the arms be being arranged side by side of staggering mutually nearby.
