Description

Technical Field

[0001] This utility model relates to the technical field of winding devices for bag making machines, specifically a winding device for bag making machines with a limiting structure. Background Technology

[0002] After the bags are made, they need to be rolled up. However, the traditional bag making machine's book-rolling device does not have a certain limiting structure, which makes the rolled bags uneven. At the same time, the bags have a certain elasticity, and the conventional rolling device does not have tension adjustment, which makes the bags loose. Therefore, a lot of labor is needed to re-roll them. In order to avoid such problems, a bag making machine rolling device with limiting and tensioning capabilities has been designed.

[0003] A winding device with a limiting structure for plastic product manufacturing, authorized by announcement number CN215885663U, includes a combination mechanism, an antistatic mechanism, a tension mechanism, and a limiting mechanism. The antistatic mechanism is connected to the middle of the combination mechanism, and the tension mechanism is located below it. The limiting mechanism is connected to the middle of the combination mechanism. The antistatic mechanism includes a rubber shaft located at the upper end of the combination mechanism and a conductive block located on the outer surface of the rubber shaft. This winding device with a limiting structure for plastic product manufacturing uses a motor in the combination mechanism to drive the winding shaft to rotate clockwise, winding the raw material into the inner walls on both sides. The conductive block contacts the conductive gears, guiding the generated static electricity to an ionization box for treatment. The motor drives a transmission belt to rotate clockwise, which in turn drives a lead screw, whose threads unwind the plastic material in contact with the lead screw.

[0004] Based on existing solutions and actual production and processing, current bag-making machine winding devices still have some problems: they are not convenient for tensioning the wound bags, not convenient for limiting the winding of the bags, cannot prevent winding deviation, and are not convenient for installation with different sizes of winding sleeves. Therefore, this utility model provides a bag-making machine winding device with a limiting structure to solve the above-mentioned problems. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a winding device for a bag making machine with a limiting structure, comprising: a workbench for installation, and a support frame fixedly installed on the upper end of the workbench;

[0007] It also includes: a first take-up column, wherein the first take-up column is installed on the upper left side of the support frame, and a threaded rod is provided in the middle of the support frame, and the upper end of the threaded rod is connected to a first bevel tooth, and the upper end of the first bevel tooth is connected to a second bevel tooth;

[0008] A bidirectional threaded screw is located on the upper right side of the worktable.

The second connecting frame is located in front of the first connecting frame. A transmission block is installed on the upper end of the first and second connecting frames, and a fixed rod is provided inside the transmission block. A spring and a sliding block are provided on the outer side of the fixed rod, and the sliding block is located in front of the spring. A third motor is located at the rear end of the first connecting frame.

[0009] Preferably, the outer side of the threaded rod is connected to the connecting block by a thread, and the threaded rod and the connecting block are symmetrically arranged about the center line of the worktable.

[0010] Preferably, a connecting block is connected to the outer side of the middle part of the threaded rod, and a second take-up column is installed at the front end of the connecting block. A third take-up column is provided on the right side of the second take-up column, and a fourth take-up column is provided on the right side of the third take-up column. A brush column is provided at the lower end of the fourth take-up column.

[0011] Preferably, the upper end of the first bevel tooth is connected to the second bevel tooth by meshing, and a transmission rod is provided in the middle of the second bevel tooth, and a first motor is installed at the rear end of the transmission rod.

[0012] Preferably, the upper, lower, left and right ends of the second take-up column are provided with sliding grooves, and the inside of the sliding grooves is connected to a limiting baffle. The limiting baffle forms a sliding structure on the outside of the second take-up column, and the limiting baffle is arranged symmetrically about the center line of the second take-up column.

[0013] Preferably, the outer side of the fixing rod is fitted with the spring, and the sliding block forms a sliding structure on the outer side of the fixing rod. The right end of the sliding block is connected to a connecting rod, and the right end of the connecting rod is connected to a clamping arm.

[0014] Preferably, the right side of the sliding block and the connecting rod form a rotating structure, and the connecting rod and the clamping arm form a rotating structure. The fixed rod, spring, sliding block, connecting rod and clamping arm are symmetrically arranged about the center line of the transmission block, and the rear end of the fixed rod is stably connected to the third motor.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the bag-making machine winding device with a limiting structure facilitates the tensioning of the wound bags, facilitates the limiting winding of the wound bags, avoids winding deviation, and is easy to install for different sizes of winding sleeves.

[0016] 1. The device is equipped with a threaded rod, a first bevel tooth, and a connecting block. When tensioning of the roll bag is required, the first motor is started to drive the second bevel tooth to rotate through the transmission rod. The lower end of the second bevel tooth is connected to the first bevel tooth in an meshing manner. Therefore, the second bevel tooth drives the threaded rod to rotate through the first bevel tooth, which causes the threaded rod to drive the connecting block to move downward. The connecting block then adjusts the second winding column to tension the bag, making it easier to tension the roll bag.

[0017] 2. It is equipped with a second winding post, a chute, and a limiting baffle. When it is necessary to limit the winding of the bag, the position of the limiting baffle outside the second winding post can be adjusted. The limiting baffle moves along the path of the chute, and the limiting baffle has a certain friction when moving inside the chute. Therefore, the limiting baffle is not easy to loosen when it interacts with the outside of the second winding post, which makes it easy to limit the winding of the bag and avoid winding deviation.

[0018] 3. It is equipped with a transmission block, a sliding block and a clamping arm. When different sizes of sleeves need to be installed for winding, one end of the sleeve can be slid backward along the front path of the clamping arm. The clamping arm will drive the connecting rod to rotate left and right according to the diameter of the sleeve, pushing the sliding block to squeeze the spring and complete the position adjustment of the clamping arm until it is completely inserted into the sleeve. This is convenient for the installation of different sizes of winding sleeves. Attached Figure Description

Detailed Implementation

[0025] 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.

[0026] Please see Figure 1-5 This utility model provides a technical solution: a winding device for a bag making machine with a limiting structure, including a worktable 1, a support frame 2, a first winding column 3, a threaded rod 4, a first bevel tooth 5, a second bevel tooth 6, a transmission rod 7, a first motor 8, a connecting block 9, a second winding column 10, a sliding groove 11, a limiting baffle 12, a third winding column 13, a fourth winding column 14, a brush column 15, a bidirectional threaded screw 16, a second motor 17, a first connecting frame 18, a second connecting frame 19, a transmission block 20, a fixing rod 21, a spring 22, a sliding block 23, a connecting rod 24, a clamping arm 25, and a third motor 26.

[0027] When using a bag-making machine winding device with a limiting structure, such as Figure 1 , Figure 2 and Figure 4As shown, a first take-up column 3 is installed on the upper left side of the support frame 2, and a threaded rod 4 is provided in the middle of the support frame 2. A first bevel tooth 5 is connected to the upper end of the threaded rod 4, and a second bevel tooth 6 is connected to the upper end of the first bevel tooth 5. A transmission rod 7 is provided in the middle of the second bevel tooth 6, and a first motor 8 is installed at the rear end of the transmission rod 7. A connecting block 9 is connected to the outer side of the middle of the threaded rod 4, and a second take-up column 10 is installed at the front end of the connecting block 9. Slide grooves 11 are provided at the upper, lower, left, and right ends of the second take-up column 10, and a limit baffle 12 is connected inside the slide grooves 11. A third take-up column 13 is provided on the right side of the limit baffle 12, and a fourth take-up column 14 is provided on the right side of the third take-up column 13. A brush column 15 is provided at the lower end of the fourth take-up column 14. First, the bag produced by the bag making machine is inserted through the upper end of the first take-up column 3, and then... The bag is wound up through the lower end of the second winding column 10, the upper end of the third winding column 13, and between the fourth winding column 14 and the brush column 15, and finally onto the sleeve. During winding, it needs to be limited and tensioned. The outer limiting baffle 12 of the second winding column 10 slides along the path of the slide groove 11 to limit the bag winding and prevent the winding from deviating. At the same time, the first motor 8 is started to drive the second bevel tooth 6 to rotate through the transmission rod 7. The lower end of the second bevel tooth 6 is connected to the first bevel tooth 5 in an meshing manner. The second bevel tooth 6 drives the threaded rod 4 to rotate through the first bevel tooth 5. The threaded rod 4 then drives the second winding column 10 to move downward through the connecting block 9. The second winding column 10 then tensions the lower end of the bag. This is the usage method of the winding device for the bag making machine with the limiting structure.

[0028] When it is necessary to install and process take-up sleeves of different sizes, such as Figure 1 , Figure 3 and Figure 5As shown, a second motor 17 is connected to the rear end of the bidirectional threaded screw 16, and a first connecting frame 18 and a second connecting frame 19 are connected to the outer side of the bidirectional threaded screw 16. The second connecting frame 19 is located in front of the first connecting frame 18. A transmission block 20 is installed on the upper end of the first connecting frame 18 and the second connecting frame 19, and a fixing rod 21 is provided inside the transmission block 20. A spring 22 and a sliding block 23 are provided on the outer side of the fixing rod 21, and the sliding block 23 is located in front of the spring 22. A connecting rod 24 is connected to the right end of the sliding block 23, and a clamping arm 25 is connected to the right end of the connecting rod 24. A third motor 26 is provided at the rear end of the first connecting frame 18. First, one end of the winding sleeve is connected to the clamping arm 25. The front side of the clamp 25 is attached and slides backward along the front path of the clamping arm 25. This causes the clamping arm 25 to rotate left and right according to the diameter of the sleeve, pushing the sliding block 23 to squeeze the spring 22, thus adjusting the position of the clamping arm 25. At this time, the second motor 17 is started to drive the bidirectional threaded screw 16 to rotate. The bidirectional threaded screw 16 drives the first connecting frame 18 and the second connecting frame 19 to move towards the center. The second connecting frame 19 then drives the adjustment device set at the upper end to be inserted into the front end of the winding sleeve, which can stabilize the position of the winding sleeve. The third motor 26 is started, which can drive the winding sleeve drill to rotate and wind the sleeve through the transmission block 20. This is the installation method applicable to different winding sleeves.
