Description

Technical Field

[0001] This utility model relates to a bag making machine feeding mechanism, specifically an automatic feeding mechanism for bag making machine rolls, and belongs to the technical field of bag making machine feeding mechanisms. Background Technology

[0002] A bag-making machine is a machine used to make various plastic packaging bags or other material packaging bags. It is widely used in the food, clothing, daily necessities and other industries. During the use of the bag-making machine, the roll material needs to be fed by the feeding mechanism. When feeding, the air shaft passes through the roll material. Then, under the action of the cylinder, the two pallets will lift the air shaft to the designated position, thereby realizing the automatic feeding of the roll material.

[0003] However, after the air shaft moves to the designated position, it is necessary to push the air shaft left and right to adjust the position of the coil. Due to the lack of positioning, it is often necessary to move the air shaft multiple times to adjust the position. This process is quite time-consuming and labor-intensive, resulting in poor operation convenience. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic feeding mechanism for bag making machine rolls in order to solve the above problems. When the air shaft moves to the designated position, it can be positioned, thus avoiding the need to spend a lot of time and effort to adjust the position of the air shaft, and effectively improving the convenience of operation.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: an automatic feeding mechanism for a bag-making machine, comprising a support base, a feeding structure on the support base, the feeding structure including a connecting shaft and a support plate, a connecting shaft rotatably connected to the support base, two support plates fixedly connected to the connecting shaft, grooves on the support plates, four rotating wheels rotatably connected to the support plates, a connecting rod fixedly connected to the support plates, a sliding rod slidably connected to the connecting rod, a connecting sleeve fixedly connected to the sliding rod, a rotating block rotatably connected to the connecting sleeve, an air shaft on the two support plates, the air shaft abutting against the eight rotating wheels, one end of the air shaft abutting against one of the rotating blocks, and the other end of the air shaft abutting against another rotating block, a limiting structure on the sliding rod, and two cylinders mounted on the support base, one end of each cylinder rotatably connected to an adjacent support plate.

[0006] Preferably, the slide bar has an overall L-shaped structure, and the connecting rod has a rectangular cross-section.

[0007] Preferably, the tray is perpendicular to the connecting shaft, and the two trays are symmetrically distributed about the middle of the connecting shaft.

[0008] Preferably, the limiting structure includes a slider and a guide groove. The slider is slidably connected to the slide rod, and the slider is provided with four guide grooves. Two locking blocks are slidably connected to the slide rod, and the connecting rod is provided with four locking slots. The locking blocks engage with adjacent locking slots, and two guide shafts are fixedly connected to the locking blocks. The guide shafts extend into the interior of adjacent guide grooves and are slidably connected to the slider.

[0009] Preferably, the slide bar is provided with a spring inside, one end of the spring abutting against the slider and the other end of the spring abutting against the slide bar.

[0010] Preferably, the two adjacent guide grooves form a V-shaped structure, and the cross-section of one end of the card block is trapezoidal.

[0011] Preferably, the width of one end of the slider is greater than the width of the other end, and one end of the slider extends to the outside of the slider rod.

[0012] Preferably, the support base is provided with a driving structure and multiple mounting slots.

[0013] Preferably, the drive structure includes a support plate and a motor. The support plate is fixedly connected to the support base, and the motor is mounted on the support plate. A first gear is fixedly connected to the output shaft of the motor, and a second gear is fixedly connected to the air shaft. The first gear and the second gear mesh with each other.

[0014] The beneficial effects of this utility model are as follows: When feeding the coil material, the air shaft can be passed through the coil material and then fixed between the air shaft and the coil material. After the air shaft passes through the coil material, two cylinders can be activated simultaneously. The simultaneous contraction of the two cylinders will drive the pallet to rotate. The rotation of the pallet will lift the air shaft. When one side of the pallet moves to contact the support seat, the cylinder stops contracting. At this time, the coil material reaches the designated position, and then the slide rod can be pushed. The slide rod will drive the connecting sleeve and the rotating block to rotate together. When the slide rod moves to the designated position, the limiting structure will limit the slide rod. At this time, the slide rod will be unable to move. Then the air shaft can be pushed so that one end of it contacts the rotating block. At this time, the air shaft is quickly positioned, avoiding the need to adjust the position of the air shaft multiple times, thus effectively saving time and energy and improving the convenience of operation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an automatic feeding mechanism for a bag-making machine includes a support base 1. A feeding structure 2 is provided on the support base 1. The feeding structure 2 includes a connecting shaft 201 and a support plate 202. The connecting shaft 201 is rotatably connected to the support base 1. Two support plates 202 are fixedly connected to the connecting shaft 201. The support plates 202 have grooves 203. Four rotating wheels 204 are rotatably connected to the support plates 202. A connecting rod 205 is fixedly connected to the support plate 202. A sliding rod 206 is slidably connected to the connecting rod 205. A connecting sleeve 207 is fixedly connected to the slide rod 206, and a rotating block 208 is rotatably connected to the connecting sleeve 207. An air shaft 3 is provided on the two support plates 202. The air shaft 3 abuts against the eight rotating wheels 204. One end of the air shaft 3 abuts against one of the rotating blocks 208, and the other end of the air shaft 3 abuts against the other rotating block 208. A limiting structure 4 is provided on the slide rod 206. Two cylinders 209 are installed on the support base 1. One end of the cylinder 209 is rotatably connected to the adjacent support plate 202.

[0022] As a technical optimization solution of this utility model, such as Figure 3As shown, the slide bar 206 has an overall L-shaped structure, and the connecting rod 205 has a rectangular cross-section, thus allowing the slide bar 206 to move only in one direction.

[0023] As a technical optimization solution of this utility model, such as Figure 1 As shown, the pallet 202 is perpendicular to the connecting shaft 201, and the two pallets 202 are symmetrically distributed about the middle of the connecting shaft 201. Therefore, the two ends of the air shaft 3 can be supported by the two pallets 202, thereby realizing automatic feeding of the coil.

[0024] As a technical optimization solution of this utility model, such as Figure 2 and Figure 3 As shown, the limiting structure 4 includes a slider 401 and a guide groove 402. The slider 401 is slidably connected to the slider rod 206. The slider 401 is provided with four guide grooves 402. Two locking blocks 404 are slidably connected to the slider rod 206. The connecting rod 205 is provided with four slots 405. The locking blocks 404 engage with adjacent slots 405. Two guide shafts 403 are fixedly connected to the locking blocks 404. The guide shafts 403 extend into the interior of adjacent guide grooves 402 and are slidably connected to the slider 401. Therefore, the slider rod 206 can be limited after it moves to a specified position.

[0025] As a technical optimization solution of this utility model, such as Figure 3 As shown, the slide bar 206 is provided with a spring 406 inside. One end of the spring 406 abuts against the slider 401, and the other end of the spring 406 abuts against the slide bar 206. Therefore, under the action of the spring 406, the locking block 404 can automatically engage with the locking slot 405.

[0026] As a technical optimization solution of this utility model, such as Figure 3 and Figure 4 As shown, the two adjacent guide grooves 402 form a V-shaped structure, and the cross-section of one end of the locking block 404 is a trapezoidal structure, so it can play a guiding role when the locking block 404 and the locking groove 405 are engaged.

[0027] As a technical optimization solution of this utility model, such as Figure 3 As shown, the width of one end of the slider 401 is greater than the width of the other end, and one end of the slider 401 extends to the outside of the slider 206, thus making it easy to press the slider 401.

[0028] As a technical optimization solution of this utility model, such as Figure 1As shown, the support base 1 is provided with a driving structure 5 and multiple mounting slots 6, so the support base 1 can be installed and fixed by bolts through the mounting slots 6.

[0029] As a technical optimization solution of this utility model, such as Figure 1 As shown, the drive structure 5 includes a support plate 501 and a motor 502. The support plate 501 is fixedly connected to the support base 1, and the motor 502 is mounted on the support plate 501. A first gear 503 is fixedly connected to the output shaft of the motor 502, and a second gear 504 is fixedly connected to the air shaft 3. The first gear 503 and the second gear 504 mesh with each other, so the air shaft 3 can be driven to rotate, thereby realizing the unloading of the coiled material.

[0030] In use, when feeding the coiled material, the air shaft 3 is passed through the coiled material and then fixed to it. After the air shaft 3 passes through the coiled material, two cylinders 209 are simultaneously activated. The simultaneous contraction of the two cylinders 209 causes the support plate 202 to rotate. The rotation of the support plate 202 lifts the air shaft 3. When one side of the support plate 202 moves to contact the support base 1, the cylinders 209 stop contracting. At this time, the coiled material reaches the designated position. Then, by pressing the slider 401, the spring 406 contracts, and the slider 401 moves... While the guide shaft 403 moves, it will move inside the guide groove 402. Simultaneously, the locking block 404 will move away from the locking groove 405. When the locking block 404 is not engaged with the locking groove 405, the slide rod 206 can be pushed. The slide rod 206 will drive the connecting sleeve 207 and the rotating block 208 to rotate together. As the slide rod 206 moves, the two locking blocks 404 will engage with the other two locking grooves 405 respectively. At this time, the slide rod 206 will be unable to move. Then, the air shaft 3 can be pushed so that one end abuts against the rotating block 208. This achieves rapid positioning of the air shaft 3, avoiding the need for multiple adjustments, thus effectively saving time and effort and improving operational convenience. When one of the rotating blocks 208 abuts against one end of the air shaft 3, it can push the other slide rod 206 to abut against the other end of the air shaft 3, thereby achieving further positioning of the air shaft 3 and preventing it from moving left or right during rotation. Furthermore, since the end of the air shaft 3 is located inside the connecting sleeve 207, it also prevents it from moving up or down during rotation. The air shaft 3 is fully positioned, which effectively improves the stability of the air shaft 3 during rotation. During the operation of the bag making machine, the motor 502 can be started. The output shaft of the motor 502 rotates, which drives the first gear 503 to rotate. The first gear 503 drives the second gear 504 to rotate, which in turn drives the air shaft 3 to rotate. The rotation of the air shaft 3 will realize the automatic feeding of the roll material. During the rotation of the air shaft 3, multiple rotating wheels 204 will rotate, which can reduce friction and resistance, making it easier to use.
