TECHNICAL FIELD

[0001] The utility model belongs to the technical field of film processing and transportation, specifically relates to a film processing feeding structure. BACKGROUND

[0002] In the single-layer film blow molding and winding process, the existing process has the problems of low separation efficiency and uneven winding after separation, the specific process is: the molten raw material is extruded to form a circular cross-section film by a blow molding machine, and after cooling and shaping, the film is cut longitudinally from both sides by a cutting device to separate the circular film into two layers of planar film, but in actual production, the two layers of film after cutting often adhere closely due to factors such as static adsorption, surface tension or uneven equipment traction, which makes it difficult to separate naturally, and the operator needs to manually intervene frequently, and the two layers of film are separated and guided to different winding shafts by tools or manual methods, which not only increases the labor cost, but also easily causes film wrinkles, tension fluctuations and other problems due to insufficient manual operation accuracy, directly affecting the product quality stability SUMMARY

[0003] The utility model aims at providing a film processing feeding structure to solve the problems in the background art.

[0004] To achieve the above technical purpose, the utility model adopts the following technical scheme:

[0005] A film processing feeding structure, comprising four support columns, a horizontal frame is arranged on the upper side of the four support columns, transmission wheels are arranged on the left and right sides of the horizontal frame, a turnover mechanism is arranged on the left side of each of the two transmission wheels, the turnover mechanism comprises two mounting blocks connected with the horizontal frame, a rotating shaft is rotatably connected between the two mounting blocks, a connecting piece is rotatably connected with the rotating shaft, a triangular plate is connected with the connecting piece, an angle adjusting assembly is assembled on the lower side of the triangular plate, the angle adjusting assembly is used for adjusting the angle of the triangular plate, and a feeding mechanism is arranged between the four support columns.

[0006] The angle adjusting assembly comprises an electric telescopic rod, rotating blocks are connected to the left and right ends of the electric telescopic rod, a horizontal rod is arranged between the two support columns on the left and right sides, the horizontal rod is provided with a first mounting seat, a stabilizing rod is arranged in the middle of the triangular plate, the stabilizing rod is provided with a second mounting seat, and the two rotating blocks are rotatably connected with the first mounting seat and the second mounting seat respectively.

[0007] The side surfaces of the two triangular plates are arc-shaped.

[0008] Two mounting rods are arranged between the two supporting columns, the feeding mechanism is arranged between the two mounting rods, the feeding mechanism comprises a guiding assembly and a flattening assembly, the guiding assembly comprises two fixed plates, the two fixed plates are connected with the two mounting rods respectively, two guiding wheels are rotatably connected between the two fixed plates, and the two guiding wheels are horizontally arranged.

[0009] The flattening assembly comprises two vertical plates, the two vertical plates are connected with the two mounting rods respectively, two flattening wheels are rotatably connected between the two vertical plates, and the two flattening wheels are arranged in a vertical mode.

[0010] The guiding assembly and the flattening assembly are provided with a tightening assembly, the tightening assembly is provided with two mounting pieces, sliding blocks are slidably arranged on the two mounting pieces, and a tightening wheel is rotatably connected between the two sliding blocks.

[0011] The triangular plate and the connecting piece are detachably connected.

[0012] Compared with the prior art, the utility model has the following technical advantages:

[0013] 1. The traditional double feeding system needs to configure independent transmission paths for two layers of films, resulting in a large horizontal land area of the equipment. After optimization, a single feeding mechanism is designed, and double-layer film collinear transportation is realized through a triangular plate shunt structure, and two-way conveying paths are integrated into a vertical space superposition layout. This design not only reduces the ground area occupied by the equipment, but also makes the overall structure of the equipment more compact, and adapts to the flexible deployment needs of different scale workshops, especially for space-limited processing scenes. The transmission wheel and the triangular plate cooperate to complete the separation, turning and shunt conveying of double-layer films, reduce manual intervention, improve the continuity of transportation, and reduce the operation intensity.

[0014] 2. During transportation, the film is prone to wrinkles or sliding due to uneven tension, affecting the winding flatness. After optimization, the combination of flattening wheels and tightening wheels is introduced: the flattening wheels apply reverse friction to the film through the upper and lower pressure rollers to eliminate horizontal wrinkles; the tightening wheel adjusts the depth of the lower pressure through the sliding block to dynamically balance the longitudinal tension of the film. The two-stage regulation mechanism keeps the film in a stable stretching state during transportation, significantly reduces the end face misregistration rate after winding, and reliably guarantees product consistency.

[0015] 3. The traditional triangular plate and transmission mechanism are usually fixedly connected, and need to be disassembled as a whole when replaced, which is time-consuming and easy to cause secondary damage. After optimization, a detachable connecting piece is used to realize quick replacement of the triangular plate, so that maintenance personnel can replace the parts without disassembling the transmission shaft, shorten the operation time, and at the same time, the electric telescopic rod integrates the angle adjustment function, accurately controls the inclination angle of the triangular plate through the electric control system, avoids the wear and tear problem of mechanical adjustment, and further reduces the equipment failure rate and maintenance cost.

[0023] Support column 1, cross frame 12, transmission wheel 13, mounting block 14, rotating shaft 15, connecting piece 16, triangular plate 17, electric telescopic rod 2, rotating block 21, cross rod 22, first mounting seat 23, stabilizing rod 24, second mounting seat 25, mounting rod 3, fixed plate 31, guide wheel 32, vertical plate 33, flattening wheel 34, mounting piece 35, sliding block 36, taut wheel 37. Specific implementation

[0024] In order to make the technical personnel in the field better understand the utility model, the utility model technical scheme is further explained below in conjunction with the drawings and examples.

[0025] As Figures 1-5 The utility model discloses a feeding structure for film processing, including four support columns 1, four support columns 1 upside is equipped with cross frame 12, and the left and right sides of cross frame 12 are equipped with transmission wheel 13, and the left side of two transmission wheels 13 is equipped with the turnover mechanism, and the turnover mechanism includes two mounting blocks 14 with cross frame 12 connection, and the rotating joint of two mounting blocks 14 has rotating shaft 15, and rotating shaft 15 rotating joint has connecting piece 16, and connecting piece 16 is connected with triangular plate 17, and the lower side of triangular plate 17 is assembled with angle adjusting assembly, and angle adjusting assembly can be used for adjusting the angle of triangular plate 17, and the feeding mechanism is equipped between four support columns 1.

[0026] After the film with a semicircular cut is cut on both sides, the two films are overlapped together, and the two overlapped films can be transported to the right side of the transmission wheel 13 from the right side. The upper film is continuously moved to the left side of the transmission wheel 13, and the lower film is turned down to contact the side of the triangular plate 17 and is bent. The side of the triangular plate 17 turns the film to match the feeding mechanism. The upper film is transported to the upper side of the left transmission wheel 13, and then passes through the side of the left triangular plate 17, which is the same as the upper side. The upper film can be bent to ensure that the upper film also matches the feeding mechanism. Therefore, such a design can ensure that the two films are separated and transported to the winding mechanism from the left and right sides of the feeding mechanism after the two films are separated at the end of the film. The two films are wound separately. Such a design only needs to guide the two triangular plates 17 to match the two triangular plates 17 after the two films are separated at the end of the film. During the transportation process, the two films can be continuously separated and stably transported, which can ensure the flatness of the film and improve the winding efficiency and flatness of the film. The design of the two triangular plates 17 turning the two films can ensure that the two films pass through one feeding mechanism without connecting two feeding mechanisms. At the same time, such a design can ensure that the feeding mechanism can be installed below the two transmission wheels 13, which can reduce the occupied space of the structure and save space during installation in the factory.

[0027] The angle adjusting assembly comprises an electric telescopic rod 2, both ends of the electric telescopic rod 2 are connected with rotating blocks 21, a cross rod 22 is arranged between the two support columns 1 on the left and right sides, the cross rod 22 is provided with a first mounting seat 23, a stabilizing rod 24 is arranged in the middle of the triangular plate 17, the stabilizing rod 24 is provided with a second mounting seat 25, and the two rotating blocks 21 are rotationally connected with the first mounting seat 23 and the second mounting seat 25 respectively.

[0028] Both ends of the electric telescopic rod 2 are connected with rotating blocks 21, the two rotating blocks 21 are rotationally connected with the first mounting seat 23 and the second mounting seat 25 respectively, and the first mounting seat 23 and the second mounting seat 25 are connected with the triangular plate 17 and the support column 1 through the cross rod 22 and the stabilizing rod 24 respectively. Therefore, when the electric telescopic rod 2 starts to stretch, the triangular plate 17 is lifted to increase the height of the triangular plate 17. When the electric telescopic rod 2 is retracted, the triangular plate 17 is driven to rotate downward to reduce the height of the triangular plate 17. In this way, the angle of the triangular plate 17 can be effectively adjusted.

[0029] The sides of the two triangular plates 17 are arc-shaped. The arc-shaped design of the side of the triangular plate 17 can prevent the triangular plate 17 from damaging the film.
