Description

Improvement of the packaging device for the folded bag

The present invention relates to a packaging device for a folding bag, which is provided with a conveying belt for carrying and translating the packaging bag, and a bag feeding unit, a bag opening unit, and a bag material respectively are arranged above the conveying belt in the translation range. The horizontal and vertical sealing and cutting unit allows the folded bag to be fed into the packaged bag material, and then the bag is sealed and cut through the transfer of the predetermined length of the conveyor belt to achieve the purpose of bag packaging.

The new patent No. 107210566 "Packing device for bag-folding" previously applied by the applicant is a bag that is cut into the packaging device after being folded into a packaging device and folded at the side after packaging. The material is sent to a bag opening mechanism, so that the bag material is opened and stretched, so that the folded vest bag is transferred into the bag material, and then passed under the pinch conveying mechanism of the roller pinch conveying mechanism to pass A bag side longitudinal sealing mechanism seals the side of the bag material, and then through the transfer mechanism to continue to pull the bag material outward to the sealing and cutting position, and the bag between the two pairs of vest bags is carried out. The operation of sealing and cutting, and finally finishing the finished product of the package is transferred backward and released, so that the operation of bag making and packaging can be continuously and automated.

However, the rotation of the package material is completed by the cooperation of the auxiliary transfer roller mechanism, the roller pinch conveying mechanism, and the transfer mechanism. The overall mechanism is slightly complicated, and the control program cannot be simplified. At the same time, the conveying mechanism of three bags of bags is easier to transport. Unexpected problems occur during the process, which in turn affects the smooth operation of the packaging operation.

In addition, if the vest bag itself is made of an environmentally-friendly material that is disintegrated, it is thin and soft, and the surface is relatively slippery, and after being folded in a stack, after being clamped and conveyed by the roller to press the conveying mechanism, The clamping entrance of the two rollers is to press the outer layer of the whole vest bag by the clamping force, which causes the vest bag of the middle layer to be easily slipped, which not only causes the stack of vest bags to spread, but also affects the subsequent packaging. Neat, it will cause difficulties in transportation, or can not be transported, which will seriously affect the smooth operation of packaging operations.

The reason is that in order to improve the above-mentioned problems that the slippery surface of the bag which is known to be slippery when it is transported through the roller clamp is easy to be slid, and the mechanism and control such as transfer sealing and cutting are complicated, the present invention provides a bag for holding and conveying the packaging bag material. A feeding unit of the conveyor belt is connected to the rear side of the material feeding unit, and a bag opening unit for opening the bag material, a pair of bag materials transversely sealing and cutting the transverse sealing and cutting unit are sequentially arranged above the conveyor belt. a longitudinal sealing unit for longitudinal sealing of a pair of bag materials, and a compacting unit for compacting and stacking the bag to facilitate sealing and sealing of the bag material, not only simplifying the construction of the packaging device, but also making the packaged stack of bags, together with the packaging bag material During the transfer process, it can be carried out more smoothly without the slippage.

The technical solution adopted by the present invention to solve the technical problem is as follows: a rear side of the feeding unit for supplying the packaging material which is cut off at the side is provided with a translational carrying unit for the conveyor belt, and is oriented on the conveyor belt. A bag feeding unit capable of lifting and supporting the feeding roller is arranged in sequence, and a bag opening member which can be raised and lowered to sandwich the upper edge of the bag is disposed opposite to the left and right sides of the translation carrying unit. The bag opening unit and a bag anti-retraction unit capable of lifting and lowering the bag element, and then sequentially setting a lifting and cutting knife to carry the bag a transverse sealing and cutting unit which cuts the transverse sealing, a longitudinal sealing unit which can lift and lower the sealing knife which seals the bag material, and a lifting device which is arranged on the corresponding side of the longitudinal sealing unit to lift the bag together with the bag Compaction unit for compacted compacted components.

Therefore, the bag opening unit, the transverse sealing and cutting unit, the longitudinal sealing unit and the compacting unit which are sequentially disposed through the above-mentioned novel are disposed above the conveyor belt of a carrier bag and above the front side of the conveyor belt. A bag feeding unit for synchronously pulling the bag material is arranged, so that the bag material can be transferred into the horizontal sealing and cutting unit and the longitudinal sealing unit without being slid out after being fed into the folded bag. Then, the compacted unit is compacted and fixed by the compacting unit to seal and cut the bag, so that the entire packaging operation can be smoothly carried out continuously.
