Description

Technical Field

[0001] This utility model relates to the technical field of plastic woven bag production equipment, and in particular to a plastic woven bag winding and storage device. Background Technology

[0002] The main production process of plastic woven bags is to use plastic raw materials to extrude film, cut, and unidirectionally stretch into flat yarns, which are then woven into products, generally called woven bags. Before sewing the bottom and sides, plastic woven bags need to be rolled up and stored to facilitate mass production later. When winding plastic woven bags, a winding machine is generally used.

[0003] Existing winding machines have weak anti-loosening capabilities for materials. After the material is wound and cut, it is easy for it to become loose due to loss of tension, which leads to a decrease in winding effect. Furthermore, there is no feedback capability after winding is completed, and the device will continue to wind the material, resulting in over-winding.

[0004] Therefore, to address the above problems, a plastic woven bag winding and storage device can be designed. During the winding process, pressure is applied to the woven bag material to ensure the density of the winding. In addition, a feedback function is added so that the device can automatically stop winding when a certain degree of winding is reached. Utility Model Content

[0005] To overcome the fact that most winding machines have a weak ability to prevent materials from loosening, after the material is wound and cut, the material is prone to become loose due to loss of tension, which leads to a decrease in winding effect. In addition, there is no feedback capability after winding is completed, and the device will continue to wind the material, which will lead to over-winding.

[0006] The technical solution of this utility model is as follows: a plastic woven bag winding and storage device, including a take-up roller, a pressure roller, and a feedback component. The feedback component includes a first contact and a second contact. A drive motor is provided on one side of the take-up roller, a pressure roller is provided above the take-up roller, a first connecting seat is provided above the pressure roller, the first connecting seat is rotatably connected to the pressure roller, a first guide rod is provided above the first connecting seat, a first spring is provided on the outer side of the first guide rod, a control module is provided above the take-up roller, a second contact is provided on one side of the control module, a first contact is provided above the second contact, and the control module is electrically connected to the first contact, the second contact, and the drive motor.

[0007] Preferably, a mounting platform is provided above the take-up roller, a first guide rod passes through the mounting platform and is slidably connected to the mounting platform, and the take-up roller has a take-up groove.

[0008] Preferably, a mounting bracket is provided above the mounting platform, the mounting bracket is located directly above a set of first guide rods, and the first contact point is located at the top inner side of the mounting bracket.

[0009] Preferably, a connecting plate is provided at the bottom of the second contact, and a second guide rod is provided above both ends of the connecting plate. The second guide rod passes through the mounting bracket and is slidably connected to the mounting bracket. A second spring is provided on the outer side of the second guide rod.

[0010] Preferably, a cutting table is provided on one side of the winding roller, the cutting table has a cutting groove, and a cutting blade is provided directly above the cutting groove.

[0011] Preferably, a third guide rod is provided above the cutting blade, the third guide rod passes through the mounting platform and is slidably connected to the mounting platform, a hydraulic rod is provided above the cutting blade, and a mounting cage is provided on the outside of the hydraulic rod.

[0012] Preferably, a support frame is provided on one side of the take-up roller, and a tensioning roller is provided on the inner side of the support frame. The two sets of tensioning rollers are in opposite directions. A second connecting seat is provided on one side of the tensioning roller, and threaded rods are provided at both ends of the second connecting seat. A third spring is provided on the outer side of the threaded rod, and a nut is provided at one end of the threaded rod. The nut is threadedly connected to the threaded rod.

[0013] The beneficial effects of this utility model are:

[0014] The material is wound up by a drive motor that drives the take-up roller to rotate. A first spring applies pressure to the first connecting seat, making the pressure roller fit tightly against the material being wound. During the continuous winding process, the diameter of the material being wound increases, pushing the pressure roller upward. A first guide rod guides the movement of the pressure roller and moves upward with it. During the upward movement of the first guide rod, it pushes the second contact point upward. When the first contact point contacts the second contact point, an electrical signal is generated. After receiving the electrical signal, the control module issues a command to stop the drive motor, thereby stopping the winding. The material is then cut. Because the pressure roller presses tightly against the wound material, increasing the friction between the materials, the wound material will not become loose after cutting due to loss of tension.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1-4 This utility model provides an embodiment of a plastic woven bag winding and storage device, including a take-up roller 2, a pressure roller 4, and a feedback component. The feedback component includes a first contact 701 and a second contact 702. A drive motor 1 is disposed on one side of the take-up roller 2, and a pressure roller 4 is disposed above the take-up roller 2. A first connecting seat 401 is disposed above the pressure roller 4, and the first connecting seat 401 is rotatably connected to the pressure roller 4. A first guide rod 402 is disposed above the first connecting seat 401, and a first spring 5 is disposed on the outer side of the first guide rod 402. A control module 6 is disposed above the take-up roller 2, and a second contact 702 is disposed on one side of the control module 6. A first contact 701 is disposed above the second contact 702. The control module 6 is electrically connected to the first contact 701, the second contact 702, and the drive motor 1. The device is driven by the drive motor 1. The rotating take-up roller 2 pulls the material to take it up. The first spring 5 applies pressure to the first connecting seat 401, so that the pressure roller 4 is tightly pressed against the material being taken up. During the continuous take-up process, the diameter of the material being taken up increases continuously, pushing the pressure roller 4 to move upward. The first guide rod 402 guides the movement of the pressure roller 4 and moves upward with the pressure roller 4. During the upward movement of the first guide rod 402, it pushes the second contact 702 to move upward. When the first contact 701 contacts the second contact 702, an electrical signal is generated. After receiving the electrical signal, the control module 6 issues a command to stop the drive motor 1, thereby stopping the take-up. Then the material is cut. Because the pressure roller 4 presses the material being taken up tightly, the friction between the materials is increased, so the material being taken up will not become loose due to loss of tension after cutting.

[0022] Please see Figure 2In this embodiment, a mounting platform 201 is provided above the take-up roller 2. A first guide rod 402 passes through the mounting platform 201 and is slidably connected to the mounting platform 201. The take-up roller 2 has a take-up groove 202. A mounting frame 703 is provided above the mounting platform 201. The mounting frame 703 is located directly above a set of first guide rods 402. A first contact point 701 is located at the top inner side of the mounting frame 703. A connecting plate 706 is provided at the bottom of the second contact point 702. Second guide rods 705 are provided above both ends of the connecting plate 706. The second guide rods 705 pass through the mounting frame 703 and are slidably connected to the mounting frame 703. A second spring 704 is provided on the outer side of 705; the mounting platform 201 is used as a mounting platform for the pressure roller 4 and other components. When a new round of winding is carried out, the material can be inserted into the winding groove 202 to increase the friction between the material and the winding roller 2, making it easier for the material to be wound up. The mounting bracket 703 installs the second spring 704, the second guide rod 705 and the connecting plate 706. The second spring 704 provides a thrust to the connecting plate 706, making it easier for the second contact 702 to leave the first contact 701 and return to the initial position for reset. The second guide rod 705 guides the movement of the connecting plate 706.

[0023] Please see Figure 3 In this embodiment, a cutting table 802 is provided on one side of the take-up roller 2. The cutting table 802 has a cutting groove 803. A cutting blade 8 is provided directly above the cutting groove 803. A third guide rod 801 is provided above the cutting blade 8. The third guide rod 801 passes through the mounting platform 201 and is slidably connected to the mounting platform 201. A hydraulic rod 3 is provided above the cutting blade 8. A mounting cage 301 is provided on the outside of the hydraulic rod 3. When cutting, the hydraulic rod 3 extends and pushes the cutting blade 8 down to cut the material spread flat above the cutting table 802. The third guide rod 801 guides the movement of the cutting blade 8. The mounting cage 301 installs and fixes the hydraulic rod 3. The third spring 903 avoids the cutting blade 8.

[0024] Please see Figure 4In this embodiment, a support frame 905 is provided on one side of the take-up roller 2, and a tensioning roller 9 is provided inside the support frame 905. The two sets of tensioning rollers 9 are in opposite directions. A second connecting seat 901 is provided on one side of the tensioning roller 9. Threaded rods 902 are provided at both ends of the second connecting seat 901. A third spring 903 is provided on the outside of the threaded rod 902. A nut 904 is provided at one end of the threaded rod 902, and the nut 904 is threadedly connected to the threaded rod 902. The support frame 905 is used to install the second connecting seat 901, the threaded rod 902, the third spring 903, and the tensioning roller 9. The third spring 903 provides thrust to the tensioning roller 9, enabling the tensioning roller 9 to tension the material and ensure the density of the take-up. The nut 904 can be turned to drive the threaded rod 902 to slide within the support frame 905, applying preload to the third spring 903, thereby adjusting the tension pressure.

[0025] During winding, the third spring 903 provides thrust to the tension roller 9, enabling the tension roller 9 to tension the material and ensure winding density. The drive motor 1 drives the winding roller 2 to rotate and pull the material for winding. The first spring 5 applies pressure to the first connecting seat 401, making the pressure roller 4 fit tightly against the material being wound. During continuous winding, the diameter of the material being wound continuously increases, pushing the pressure roller 4 upward. The first guide rod 402 guides the movement of the pressure roller 4 and moves along with the pressure roller 4. During the upward movement, the first guide rod 402 pushes the connecting plate 706 upward and drives the second contact 702 upward. The second guide rod 705 guides the movement of the connecting plate 706. When the second contact 702 comes into contact with the first contact 701, an electrical signal is generated. After receiving the electrical signal, the control module 6 issues a command to stop the drive motor 1, thereby stopping the winding. Then, the hydraulic rod 3 extends to push the cutting blade 8 downward, cutting the material spread flat above the cutting table 802.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
