Description

Technical Field

[0001] This utility model relates to the field of inner lining bag processing technology, and in particular to an inner lining bag making machine. Background Technology

[0002] A liner bag making machine is a specialized piece of equipment used to produce liner bags for steel drums. These liner bags are typically used to package liquids or solids such as chemicals, oils, and food. Their purpose is to prevent leakage and contamination, while also improving packaging safety and convenience. The liner bags are pre-formed, seamless, or welded plastic bags that fit tightly inside the steel drum. They are used to hold liquids, powders, granules, or slurries, providing isolation, corrosion protection, contamination prevention, and facilitating pouring and cleaning. They are commonly used in steel drum manufacturing.

[0003] Existing technologies, such as the utility model patent with publication number CN218701698U, disclose a plastic bag making machine. This patent includes a worktable, a mounting frame, and a cutting plate. The mounting frame is equipped with a limiting component for limiting the cutting of the plastic bag, and the inner wall of the worktable is equipped with a conveying component for conveying the cut plastic bag after cutting. This utility model can limit and fix the plastic bag during cutting, thereby preventing the cutter from sticking to the blade when it rises. Furthermore, the large pressure plate area prevents wrinkles in the plastic bag, increasing the cutting quality.

[0004] During the production of steel drums, it was found that in the processing of steel drum liner bags, the steel drum liner bags are usually placed on the surface of the extrusion platform and then electrically heated for extrusion. This results in a relatively uniform size for the extruded steel drum liner bags, making it inconvenient to process steel drum liner bags of different sizes. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that in the existing technology, during the processing of steel drum liner bags, the steel drum liner bags are usually placed on the surface of the extrusion platform and then electrically heated for extrusion. This results in the steel drum liner bags having a relatively uniform extrusion size, making it inconvenient to process steel drum liner bags of different sizes.

[0006] To solve the above-mentioned technical problems, this utility model provides an inner lining bag making machine, including: a base, an adjusting device, a conductive slide rail, and a bearing plate. An operating frame is installed on one side of the base, and a cylinder is provided on the upper surface of the operating frame. A heating and forming module is provided at the output end of the cylinder. A control box is provided on one side surface of the base. The bearing plate is slidably connected to the surface of the base via the conductive slide rail. The surface of the bearing plate is fixedly connected to the bottom end of the support frame via the adjusting device. The adjusting device includes several fixed frames, the bottom end of which is fixedly connected to the bottom surface of the support frame. A rotating frame is rotatably connected to the inner wall of the fixed frame. The rotating frame has an "L" shaped cross-section. An extrusion shaft is threaded through the short arm end of the rotating frame. An extrusion plate is rotatably connected to one end of the extrusion shaft. An inlay groove is provided on both side walls of the bearing plate, and the inner wall of the inlay groove is engaged with the surface of the extrusion plate.

[0007] The effect achieved by the above components is as follows: during the manufacturing process of the inner lining bag of the steel drum, the inner lining bag of the steel drum needs to be placed on the upper surface of the support frame, and then heated and extruded by the extrusion frame and heating wire in the heating and forming module. During this process, the support frame can be replaced by the adjustment device, which facilitates the processing and use of inner lining bags of steel drums of different sizes.

[0008] Preferably, two pulley frames are fixedly connected to one side surface of the bottom end of the support frame, and a guide rail is slidably connected to the arc surface of the pulley frame. The lower surface of the guide rail is fixedly connected to one side surface of the bearing plate.

[0009] The effect achieved by the above components is that, by means of the sliding limit between the pulley frame and the guide rail, friction can be reduced when the support frame is moved and limited.

[0010] Preferably, a friction strip is fixedly connected to the inner wall surface of the inlay groove, and the surface of the friction strip abuts against the surface of the extrusion plate.

[0011] The effect achieved by the above components is that the contact area of ​​the extrusion plate can be increased by the friction strip, thereby better fixing and limiting the bottom end of the entire support frame.

[0012] Preferably, a scale is provided on one side surface of the support plate, and the length of the scale is adapted to the length of the support plate.

[0013] The effect achieved by the above components is that the distance between the two support frames can be effectively adjusted with the help of the scale, making it easier to operate and use the support frames.

[0014] Preferably, the arc surface of the support frame is provided with an auxiliary device, which includes a fixing ring, a rotating shaft, and two connecting rods. The inner wall of the fixing ring is fixedly connected to the arc surface of the support frame. A guide rod is fixedly connected to one side of the fixing ring. The two ends of the guide rod slide through the bottom end surface of the connecting rod. A limit plate is fixedly connected to the upper end of the connecting rod. The arc surfaces of the two ends of the rotating shaft are provided with threads in opposite directions. The two ends of the rotating shaft are respectively threaded through the bottom ends of the two connecting rods.

[0015] The effect achieved by the above-mentioned components is that when the inner lining bag of the steel drum is placed on the upper surface of the support frame, it can be protected with the help of auxiliary devices and squeezed and protected by the limiting plates on both sides of the upper end of the support frame, which helps to prevent the inner lining bag of the steel drum from wrinkling.

[0016] Preferably, side plates are fixedly connected to the upper two arc surfaces of the support frame, and the cross-sectional dimensions of the side plates are adapted to the cross-sectional dimensions of the upper end of the support frame.

[0017] The effect achieved by the above components is that the side plates can increase the contact area with the inner lining bag of the steel drum, making the inner lining bag of the steel drum more stable.

[0018] Preferably, the limiting plate is a rigid plastic plate, and the cross-section of the limiting plate is arc-shaped.

[0019] The effect achieved by the above-mentioned components is that, with the help of the rigid plastic limiting plate, better protection can be provided when the inner liner of the steel drum is squeezed, so as to avoid squeezing and damaging the inner liner of the steel drum.

[0020] Compared with related technologies, the inner lining bag making machine provided by this utility model has the following beneficial effects:

[0021] This utility model provides a bag making machine for inner lining bags. By operating the adjustment device, the distance and position of the two support frames are fixed, allowing the support frames to be relatively limited with the bearing plate. This facilitates the installation of support frames of different sizes and helps to conveniently extrude and heat-form the inner lining bags of steel drums.

[0022] By operating the auxiliary device, further protection of the inner liner of the steel drum is achieved. The relative position of the limiting plates on both sides of the support frame is moved by the rotating shaft, so that the limiting plates can squeeze and protect the inner liner of the steel drum that is fitted on the surface of the support frame. This helps to prevent the inner liner of the steel drum from shifting position and wrinkling during the squeezing process. Attached Figure Description

A friction strip 47 is fixedly connected to the inner wall surface of the inlay groove 45. The surface of the friction strip 47 abuts against the surface of the pressing plate 44. A scale 49 is provided on one side surface of the bearing plate 8. The length of the scale 49 is adapted to the length of the bearing plate 8.

[0032] In the embodiments of this utility model, please refer to Figure 3 The auxiliary device 5 includes a fixed ring 51, a rotating shaft 55, and two connecting rods 54. The inner wall of the fixed ring 51 is fixedly connected to the arc surface of the support frame 9. A guide rod 52 is fixedly connected to one side of the fixed ring 51.

Then, the steel drum liner bag to be processed is put on the upper surface of the support frame 9. At the same time, the auxiliary device 5 can be used for positioning and protection. Rotating the rotating shaft 55 causes the connecting rods 54 at both ends of the arc surface to move, so that the limiting plate 53 fixed at the upper end of the connecting rod 54 can squeeze the steel drum liner bag after it is put on, thereby preventing the steel drum liner bag from shifting position or wrinkling.
