Description

Technical Field

[0001] The invention relates to the technical field of packaging machinery, and in particular to a feeding system of a packaging machine. Background Art

[0002] With the development of science and technology, there is an increasing demand for automatic packaging machines that integrate functions such as bag taking, bag loading, bag filling, and bag sewing in factory production. The packaging bag is transferred to the bottom of the barrel by the bag loading mechanism, and the bag mouth of the packaging bag is sleeved on the barrel mouth. Then the bag clamping mechanism clamps the bag mouth of the packaging bag, and the barrel unloads the material to start bag filling. After the bag filling is completed, the packaging bag is clamped and sent to the subsequent sewing station by the clamping mechanism for bag sewing. The above sequence is the packaging sequence of general packaging bags, but for some packaging bags with special materials and structures, it is not suitable to use the bag loading mechanism and the bag clamping mechanism to clamp, and the bag filling must be done manually. The practice in the prior art is to set up a material guide barrel separately, and then set up a clamping mechanism and a sewing mechanism accordingly downstream, but the proportion of manual bag filling is very small after all, and it is too costly to set up a whole set of subsequent mechanisms separately for this purpose. Summary of the invention

[0003] The object of the present invention is to provide a feeding system for a packaging machine which can be loaded manually or automatically.

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a feeding system of a packaging machine, including a material receiving barrel connected to a material bin, the lower barrel mouth of the material receiving barrel is divided into two parts to form a first material discharge barrel and a second material discharge barrel, the first material discharge barrel extends to the downstream position of the bagging mechanism, and the second material discharge barrel extends to the upstream position of the clamping mechanism.

[0005] In the above scheme, the first feeding barrel extends to the downstream position of the bag loading mechanism, and the packaging bag transferred by the bag loading mechanism is put on the mouth of the first feeding barrel to realize fully automatic bag loading and material receiving. After the material receiving is completed, it is clamped and sent to the subsequent process by the clamping and sending mechanism. This is suitable for automatic bag loading of packaging bags with no special requirements. For packaging bags made of special materials that are not suitable for transfer by the bag loading mechanism, the material can be manually received at the mouth of the second feeding barrel, and then manually sent to the clamping and sending mechanism, and then clamped and sent to the subsequent process by the clamping and sending mechanism.

[0009] like Figure 1-Figure 3 As shown, a feeding system of a packaging machine includes a receiving barrel 10 connected to a silo, the lower barrel opening of the receiving barrel 10 is divided into two parts to form a first unloading barrel 11 and a second unloading barrel 12, the first unloading barrel 11 extends to the downstream position of the bag loading mechanism A, and the second unloading barrel 12 extends to the upstream position of the clamping and conveying mechanism B. The first unloading barrel 11 extends to the downstream position of the bag loading mechanism A, and the packaging bag transferred by the bag loading mechanism A is put on the barrel opening of the first unloading barrel 11 to realize full-automatic bag loading and material receiving, and after the material receiving is completed, it is clamped and conveyed to the subsequent process by the clamping and conveying mechanism B, which is suitable for automatic bag loading and material feeding of packaging bags without special requirements; for packaging bags of special materials that are not suitable for transfer by the bag loading mechanism A, the materials can be manually received at the barrel opening of the second unloading barrel 12, and then manually sent to the clamping and conveying mechanism B, and then clamped and conveyed to the subsequent process by the clamping and conveying mechanism B.

[0010] Since only a very small number of packaging bags need to be manually loaded, the feeding system should still be mainly automatic loading. The first discharge barrel 11 is arranged in a vertical direction as a whole, and the material flow rate is fast. The second discharge barrel 12 is arranged in an inclined shape and a discharge pipe 13 is connected to the barrel mouth of the second discharge barrel 12. The material flow rate is slower than that of the first discharge barrel 11. The discharge pipe 13 is arranged in a vertical direction as a whole and the discharge pipe 13 and the second discharge barrel 12 are connected by a threaded connection to form a detachable connection. When manual loading is not required, the discharge pipe 13 is removed from the lower end of the second discharge barrel 12 to avoid affecting the arrangement of other mechanisms; similarly, other components on the frame can also be set to form a sliding connection with the frame to provide space for the installation of the discharge pipe 13.

[0011] Manual bagging and material connection also require that the bag mouth be clamped on the pipe mouth of the discharge pipe 13. Therefore, two sets of clamps 131 are arranged at the lower pipe mouth of the discharge pipe 13. A hinged plate 132 is fixed on the clamp 131. The hinged plate 132 is hinged to the first hinge seat 133 on the cylinder wall through a first hinge shaft 136. The cylinder body of the first cylinder 134 is hinged to the second hinge seat 135 on the cylinder wall through a second hinge shaft 137, and the piston rod is hinged to the hinged plate 132 through a third hinge shaft 138. The axis cores of the three hinge shafts are parallel and located in the horizontal direction. The first cylinder 134 drives the hinged plate 132 to rotate around the first hinge shaft 136 to drive the two clamps 131 close to or away from the cylinder wall.

[0012] Since both automatic and manual material receiving require the use of the clamping and conveying mechanism B to transfer the packaging bags, automatic and manual material receiving are generally not performed at the same time, so a valve plate is provided in the inner cavity at the junction of the first unloading barrel 11 and the second unloading barrel 12, and the valve plate is fixed on the rotating shaft 22, and the two ends of the rotating shaft 22 protrude to the outside of the barrel and form a rotational fit with the bearing seat 23 provided on the barrel wall. Through the provision of the valve plate, the material falling from the receiving barrel 10 can come out of the first unloading barrel 11 or the second unloading barrel 12.

[0013] Furthermore, a mounting plate 24 is fixed on the outer wall of the material receiving barrel 10, and a second cylinder 25 is hinged on the mounting plate 24. One end of the rocker arm 26 is fixedly connected to the end of one of the rotating shafts 22 protruding to the outside of the barrel, and the other end is hinged to the piston rod of the second cylinder 25. The axis core of each hinge shaft is consistent with the axis core direction of the rotating shaft 22.
