[0030] The present technical solution is described in detail below in conjunction with specific embodiments.

[0031] like Figure 1-6 As shown, the present invention discloses a wide film, wide knife tube and rod packaging machine, comprising a frame 10, an upper film feeding roller and an upper film roll 81, a lower film feeding roller and a lower film roll 82, and an upper cutter. Three to four front conveyor belts 3 are arranged on the front side of the frame, and three to four rear conveyor belts 4 are arranged on the rear side of the frame. The upper film feeding roller is arranged above the front conveyor belt 3, and the lower film feeding roller is arranged below the front conveyor belt 3. A cutter holder suspension beam 102 is arranged on the frame, and a plurality of first cylinders 19 are installed on the cutter holder suspension beam. The push rod end of the first cylinder 19 passes through the cutter holder suspension beam 102 and is fixedly connected to the upper cutter beam 18; the upper cutter beam 18 is connected to the upper cutter through a plurality of connecting columns. A film cutting station 2 is arranged below the upper cutter. The upper and lower films are guided by the film guide rod 17 through the gap between the upper cutter and the film cutting station 2, and the upper cutter completes the first heat sealing. After the tube and rod 5 passes through the film cutting station from the front conveyor belt, the first cylinder 19 drives the upper cutter downward to heat-seal and cut the upper and lower films. The upper cutter includes a long knife body 11, and a plurality of knife seats 13 are connected below the long knife body. A thermal expansion reserved gap is arranged between two adjacent knife seats. An electric heating device 14 is arranged on the knife seat, and a blade 15 is arranged on each knife seat. The tube and rod to be packaged are placed horizontally on a plurality of front conveyor belts and conveyed by the front conveyor belts toward the upper cutter. Since the knife seat is divided into a plurality of short knife seats, wide knife and wide film packaging becomes possible. There are at least two film guide rods 17, and at least one film guide rod 17 is arranged for the upper and lower films, and one group of film guide rods 17 is arranged close to the film cutting station 2, so that the upper and lower films are respectively guided from the film roller to the front of the film cutting station.

[0032] The front conveyor belt 3 and the rear conveyor belt 4 are respectively arranged at the front side and the rear side of the film cutting table 2. A second cylinder 6 is arranged at the discharge end of the front conveyor belt, and the second cylinder pushes the tube rod member 5 from the front side of the film cutting table to the rear side of the film cutting table.

[0033] The upper cutter includes a guard plate 16, which is symmetrically arranged on the front and rear sides of the upper cutter. The end of the guard plate is used to flatten the upper and lower films on the front and rear sides of the blade when the upper cutter moves downward; the surface of the blade 15 is provided with a non-stick coating 151, and the end of the guard plate 16 is covered with a non-stick film 161 on the front and rear wall surfaces. The non-stick coating 151 and the non-stick film 161 are made of Teflon material, which has a good non-stick effect and is safe and reliable.

[0034] A vertical slide 162 is provided on the guard plate, and a guard plate column is fixedly connected to the blade body, and one end of the guard plate column is inserted into the vertical slide 162; the blade body and the blade seat are connected through the heat insulation block 12. The heat insulation block 12 effectively prevents the heat of the blade seat from being transferred to the blade body, and the guard plate also has a certain heat insulation effect. When the guard plate is freely hanging, the top of the vertical slide 162 is hung on the guard plate column, and the end of the guard plate is lower than the blade. When the upper cutter moves downward, the end of the guard plate first reaches the film cutting station to flatten the upper and lower films. When the blade slowly descends, the guard plate column moves up and down in the vertical slide 162 synchronously until the upper cutter reaches the film cutting station 2.

[0035] The blade holder 13 includes an upper blade holder 131 and a lower blade holder 132. The upper blade holder is axially penetrated by a heating hole 14 with a built-in electric heating device. The lower blade holder is provided with a blade mounting groove opening downward and a plurality of blade hanging holes 1321 vertically penetrating the blade mounting groove. The small blade hanging piece passes through the blade hanging hole 1321 and the blade 15. The assembly relationship between the blade 15 and the small blade hanging piece and the blade mounting groove can be a clearance fit. The electric heating device can be an electric heating rod or an electric heating wire, etc.

[0036] A knife pad 21 is arranged on the film cutting table, and a first platform 61 is arranged at the discharge end of the front conveyor belt. The first platform is used to receive the tube and rod parts unloaded from the front conveyor belt; a third cylinder 7 is arranged at the feeding end of the rear conveyor belt, and a second support plate 71 is connected to the push rod of the third cylinder. The first stroke stop of the second support plate is higher than the rear conveyor belt, and the second stroke stop is not higher than the rear conveyor belt. The knife pad 21 can be made of a softer material such as a silicone pad. The knife pad avoids the rigid contact between the blade and the film cutting table during hot cutting, and plays a protective role for the blade. The second cylinder 6 pushes the tube and rod parts away from the film cutting table 2 and is received by the second support plate 71. After the blade 15 heat-seals and cuts off the upper and lower films, the third cylinder moves downward, so that the tube and rod parts 5 fall on the feeding end of the rear conveyor belt 4.

[0037] The installation height of the first platform 61 is level with the knife pad 21 , and the position of the knife pad is higher than the first travel stop of the second support plate.

[0038] A pair of dividing plates are installed on the frame, and a blocking block 103 higher than the front conveyor belt is arranged on the dividing plate. A fourth cylinder is arranged next to the blocking block. The push rod of the fourth cylinder is connected to the feeding ramp 31. The feeding ramp is used to lift up a pipe rod member close to the blocking block and make the pipe rod member pass over the blocking block and fall onto the front conveyor belt behind the blocking block.

[0039] A feeding inclined bracket 101 is installed on the frame, and the feeding inclined bracket is connected to the feeding end of the front conveyor belt. The unloading end of the feeding inclined bracket is lower than the feeding end of the front conveyor belt. A fifth cylinder 32 is arranged at the unloading end of the feeding inclined bracket. The fifth cylinder lifts one or more pipe rods upward and conveys them to the front conveyor belt.

[0040] The packaging process of the wide film and wide knife tube and rod packaging machine of the present invention is as follows: the tube and rod are automatically packaged in a horizontal manner, which specifically includes the following steps:

[0041] 1) The first start-up of the machine to heat-seal and connect the upper and lower films: the upper and lower films are pulled through the film cutting table, and the controller drives the electric heating device in the upper knife seat shaft to start heating, so that the temperature of the blade on the lower knife seat rises to the set temperature value and remains within the set temperature value range, and then drives the first cylinder downward to the film cutting table, heat-seals the upper and lower films and then retreats;

[0042] 2) Tube and rod loading: put the tube and rod horizontally into the loading inclined bracket, and the fifth cylinder lifts the tube and rod upward and transports it to the front conveyor belt; the front conveyor belt transports the tube and rod toward the blocking block, and the blocking block arranges the tube and rod closely in front of the blocking block; the fourth cylinder lifts up a tube and rod close to the blocking block, and the fourth cylinder push rod connects the feeding inclined plate, and the lifted tube and rod falls along the feeding inclined plate onto the front conveyor belt behind the blocking block and continues to move toward the film cutting table;

[0043] 3) The tube and stick pieces fall from the discharge end of the front conveyor belt onto the first platform which is lower than the front conveyor belt. The second cylinders arranged on both sides of the front conveyor belt push the tube and stick pieces on the first platform together with the upper and lower films which have been heat-sealed and connected from the front side of the film cutting station to the rear side of the film cutting station, so that the tube and stick pieces fall onto the second support plate, which is lower than the film cutting station.

[0044] 4) The controller drives the first cylinder downward, and the heated blade heat-seals and cuts the upper and lower films;

[0045] 5) The third cylinder moves downward, causing the second support plate to drop from a position above the rear conveyor belt to a position below the rear conveyor belt. The pipe and rod pieces fall on the feeding end of the rear conveyor belt by their own weight, and the rear conveyor belt sends the pipe and rod pieces away from the frame.

[0046] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
