Description

Technical Field

[0001] This utility model relates to the field of packaging bag manufacturing technology, and in particular to a material feeding shaft for a bag making machine. Background Technology

[0002] Currently, in order to reduce the weight of plastic rolls, the rolls are generally made of wood or thick paper. However, since the rolls are in a rotating state for a long time, the rigidity of the wooden or thick paper rolls is insufficient, resulting in a short service life. Furthermore, the wear between the rolls and the feed shaft is severe, which can easily lead to the rolls bending or even breaking.

[0003] To address the aforementioned issues, existing technology CN208812627U provides a material feeding shaft for a bag-making machine, comprising a shaft body and a steel roller. A limiting cylinder and a conical fixing cylinder are coaxially mounted at the end of the shaft body. The small-diameter end of the fixing cylinder faces the middle of the shaft body, and the outer diameter of the large-diameter end of the fixing cylinder is larger than the inner diameter of the steel roller. The limiting cylinder is located on the side of the fixing cylinder away from the shaft body, and several limiting rods are vertically fixed circumferentially on the limiting cylinder. The steel roller is hollow inside and sleeved on the shaft body, with its end abutting against the fixing cylinder. This solution solves the problem of short service life of wooden rollers.

[0004] However, in the aforementioned prior art, when installing the steel roll, the steel roll is installed by the two fixed cylinders relying on a threaded connection and moving relative to each other on the two shaft bodies. This causes the fixed cylinders to loosen easily during use, resulting in the steel roll falling off. Summary of the Invention

[0005] The purpose of this utility model is to provide a material feeding shaft for a bag making machine, which solves the technical problem in the prior art where the steel roller is installed by two fixed cylinders connected by threads and moved relative to each other on the two shaft bodies. This causes the fixed cylinders to loosen during use, resulting in the steel roller falling off.

[0006] To achieve the above objectives, this utility model employs a material feeding shaft for a bag-making machine, comprising two shafts, a fixed disc, a steel roller, and two fixed components. Each fixed component includes a drive roller, a transmission assembly, a support shaft, two moving parts, two slides, two limiting rods, and two fixed rollers. The fixed disc is fixedly connected to the steel roller and located at one end of the steel roller. Each fixed disc is slidably connected to the two shafts and located at one end of the two shafts. The drive roller, the transmission assembly, the support shaft, the two moving parts, the two slides, the two limiting rods, and the two fixed rollers are respectively mounted on the corresponding shafts. The transmission assembly and... The drive roller is fixedly connected and located at one end of the drive roller. One end of each of the two moving parts is rotatably connected to the transmission assembly and symmetrically arranged at one end of the transmission assembly. The other end of each of the two moving parts is rotatably connected to the support shaft and symmetrically arranged at one end of the support shaft. One end of each slide block is slidably connected to the corresponding moving part and located at one end of the corresponding moving part. The other end of each slide block is slidably connected to the corresponding limiting rod and located at one end of the corresponding limiting rod. Each fixed rod is fixedly connected to the corresponding slide block and located at one end of the corresponding slide block. The two fixed rods cooperate with the fixed plate.

[0007] The drive roller includes a throttle and a drive shaft, the drive shaft being fixedly connected to the throttle and located at one end of the throttle.

[0008] The transmission assembly includes a transmission rod and a transmission gear. The transmission rod is fixedly connected to the drive shaft and located at one end of the drive shaft. The transmission gear is fixedly connected to the transmission rod and located at one end of the transmission rod.

[0009] Each of the moving parts includes a moving gear and a lead screw. The lead screw is fixedly connected to the moving gear and is located at one end of the moving gear. The moving gear cooperates with the transmission gear.

[0010] Each of the slide blocks includes a seat body and a limiting block. The seat body is slidably connected to the lead screw and is located at one end of the lead screw. The limiting block is fixedly connected to the seat body and is located at one end of the seat body.

[0011] This utility model discloses a material feeding shaft for a bag-making machine. The drive roller, transmission assembly, support shaft, two moving parts, two slides, two limiting rods, and two fixed rollers are respectively mounted on corresponding shaft bodies. The transmission assembly is fixedly connected to the drive roller and located at one end of the drive roller. One end of each of the two moving parts is rotatably connected to the transmission assembly and symmetrically arranged at one end of the transmission assembly.

The other end of each slide is slidably connected to a corresponding limiting rod and located at that end. Each fixed roller is fixedly connected to a corresponding... The slide is fixedly connected and located at one end of the corresponding slide. The two fixed rollers cooperate with the fixed plate. By using a wrench to rotate the two drive rollers, each drive roller drives the transmission assembly to rotate. The transmission assembly drives the two moving parts to rotate on the support shaft. The two support shafts drive the two slides to move relative to each other through the two limiting rods. The two slides move the two fixed rollers out of the corresponding shafts and insert them into the fixed plate. Thus, the steel roll is installed on the two shafts through the fixed plate. This method can effectively solve the problem that when installing the steel roll, the two fixed cylinders are installed by moving relative to each other on the two shafts through a threaded connection. This causes the fixed cylinders to loosen during use, resulting in the steel roll falling off. Attached Figure Description

[0019] This utility model provides a material feeding shaft for a bag making machine, including a shaft body 101, a fixed plate 102, a steel roller 103, a support shaft 104, a limiting rod 105, a fixed roller 106, a throttle 107, a drive shaft 108, a transmission rod 109, a transmission gear 110, a moving gear 111, a lead screw 112, a seat body 113, and a limiting block 114. The aforementioned solution solves the problem that when installing the steel roller 103, the two fixed cylinders are connected by threads and moved relative to each other on the two shaft bodies to install the steel roller 103, which leads to the fixed cylinders easily loosening during use, causing the steel roller 103 to fall off.

[0020] In this specific embodiment, the fixed disk 102 is fixedly connected to the steel roller 103 and located at one end of the steel roller 103. The fixed disk 102 is slidably connected to both shafts 101 and located at one end of each shaft 101. The drive roller, the transmission assembly, the support shaft 104, the two moving parts, the two slides, the two limiting rods 105, and the two fixed rollers 106 are respectively disposed on the corresponding shafts 101. The transmission assembly is fixedly connected to the drive roller and located at one end of the drive roller. One end of each of the two moving parts is rotatably connected to the transmission assembly and symmetrically disposed at one end of the transmission assembly. The other end of each of the two moving parts is rotatably connected to the support shaft 104 and symmetrically disposed at one end of the support shaft 104. One end of each slide is slidably connected to the corresponding moving part and located at the corresponding moving part. One end of each slide block is slidably connected to the corresponding limiting rod 105 and located at one end of the corresponding limiting rod 105. Each fixed rod 106 is fixedly connected to the corresponding slide block and located at one end of the corresponding slide block. The two fixed rods 106 cooperate with the fixed plate 102. By using a wrench to rotate the two drive rollers, each drive roller drives the transmission assembly to rotate. The transmission assembly drives the two moving parts to rotate on the support shaft 104. The two support shafts 104 drive the two slide blocks to move relative to each other through the two limiting rods 105. The two slide blocks move the two fixed rods 106 out of the corresponding shaft 101 and insert them into the fixed plate 102. Thus, the steel roll 103 is installed on the two shafts 101 through the fixed plate 102 to fix the steel roll 103 and prevent it from falling off during use.

[0021] The drive roller includes a throttle 107 and a drive shaft 108. The drive shaft 108 is fixedly connected to the throttle 107 and is located at one end of the throttle 107. When the throttle 107 is rotated using a wrench, the throttle 107 drives the drive shaft 108 to rotate.

[0022] Secondly, the transmission assembly includes a transmission rod 109 and a transmission gear 110. The transmission rod 109 is fixedly connected to the drive shaft 108 and is located at one end of the drive shaft 108. The transmission gear 110 is fixedly connected to the transmission rod 109 and is located at one end of the transmission rod 109. The drive shaft 108 drives the transmission gear 110 to rotate through the transmission rod 109.

[0023] Meanwhile, each of the moving parts includes a moving gear 111 and a lead screw 112. The lead screw 112 is fixedly connected to the moving gear 111 and is located at one end of the moving gear 111. The moving gear 111 cooperates with the transmission gear 110. The transmission gear 110 drives the moving gear 111 to rotate, and the moving gear 111 drives the lead screw 112 to rotate.

[0024] In addition, each of the slides includes a seat body 113 and a limiting block 114. The seat body 113 is slidably connected to the lead screw 112 and is located at one end of the lead screw 112. The limiting block 114 is fixedly connected to the seat body 113 and is located at one end of the seat body 113. The lead screw 112 drives the seat body 113 to move, and the seat body 113 drives the limiting block 114 to move on the limiting rod 105.

[0025] Using a bag-making machine feed shaft according to this embodiment, in specific use, the steel roller 103 is connected to the two shafts 101 via the fixed plate 102. Then, the two handles 107 are rotated using a wrench, each handle 107 driving the drive shaft 108 to rotate. The drive shaft 108 drives the transmission gear 110 to rotate via the transmission rod 109. The transmission gear 110 drives the two moving gears 111 to rotate on the support shaft 104. The two moving gears 111 drive the two... When the lead screw 112 rotates, the two lead screws 112 drive the two seats 113 to move relative to each other. The two seats 113 drive the two limiting blocks 114 to move relative to each other on the two limiting rods 105. At this time, the two seats 113 move the two fixing rods 106 out of the corresponding shafts 101 and insert them into the fixing plate 102, thereby mounting the steel roller 103 on the two shafts 101 through the fixing plate 102, thus fixing the steel roller 103 and preventing it from falling off during use.
