Description

Technical Field

[0001] This utility model relates to the field of winding equipment technology, and more specifically, to a plastic film winding equipment with anti-reverse function. Background Technology

[0002] Plastic film is short for plastic film, which is a film made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other resins. It is used for packaging and as a coating layer, and is widely used in food, medicine, chemical and other fields. In the plastic film processing, the processed plastic film needs to be rolled up tightly by winding equipment, and the resulting plastic film roll material is convenient for subsequent storage and movement.

[0003] Traditional plastic film winding equipment is mostly simple in structure, simply using a winding motor to drive the winding shaft and winding sleeve to rotate in order to achieve the winding operation of plastic film. However, since there is no anti-reverse mechanism for the winding shaft, when the winding motor stops working, the winding shaft may partially reverse, causing the tightly wound plastic film roll to loosen again, affecting the winding quality and work efficiency of the plastic film. Moreover, it is also inconvenient to remove the wound plastic film roll from the winding shaft, making it relatively impractical. Therefore, those skilled in the art have proposed a plastic film winding equipment with anti-reverse mechanism. Utility Model Content

[0006] (II) Technical Solution

[0007] To achieve the advantages of effectively preventing the plastic film roll from unwinding due to the rewinding shaft reversal, and facilitating the removal and disassembly of the wound plastic film roll, thereby improving work efficiency and enhancing practicality, the specific technical solution adopted by this utility model is as follows: A plastic film winding device with anti-reversal function includes a mounting base and a rolling shaft. Rewinding shafts are symmetrically mounted on the mounting base, and winding rollers are fixedly mounted on the winding shafts. One end of one winding shaft is connected to the output end of a winding motor. Pulleys are symmetrically fixedly mounted on one end of both winding shafts. Between the two pulleys... A drive belt is fitted onto the mounting base, and vertical plate frames are symmetrically fixedly mounted on the mounting base. Rolling grooves are symmetrically opened on the side walls of the two vertical plate frames opposite each other. A take-up sleeve is fixedly fitted onto the rolling shaft, and both ends of the rolling shaft are embedded in the rolling grooves. A ratchet is fixedly mounted on one end of the take-up shaft. A fixing block is fixedly mounted on the side wall of the mounting base, and a rotating shaft is mounted on the side wall of the mounting base. A movable plate is mounted on the rotating shaft. A pawl is fixedly mounted on one side of the movable block, and several springs are connected and installed between the bottom surface of the movable block and the top surface of the fixing block.

[0008] Furthermore, mounting brackets are symmetrically fixedly installed on one side of the top surface of the mounting base, and bidirectional lead screws are installed on the mounting brackets. Guide slide rods are fixedly installed between the two mounting brackets. Correction limiting plates are symmetrically arranged between the two mounting brackets. Lead screw sleeves are symmetrically fixedly installed on the two correction limiting plates, and the lead screw sleeves cooperate with the bidirectional lead screws. Guide slide sleeves are symmetrically fixedly installed on the two correction limiting plates, and guide slide rods are sleeved inside the guide slide sleeves.

[0009] Furthermore, a control panel is fixedly installed on the side wall of the mounting base, and the control panel is electrically connected to the winding motor.

[0010] Furthermore, an adjusting hand crank is fixedly installed at one end of the bidirectional lead screw.

[0011] Furthermore, the width of the rolling groove is greater than the diameter of the rolling shaft.

[0012] Furthermore, the rolling shaft and the take-up shaft are parallel to each other.

[0013] Furthermore, the centerlines of the two take-up shafts are on the same horizontal plane.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a plastic film winding device with anti-reverse function, which has the following beneficial effects:

[0016] (1) This utility model is provided with an installation base and a rolling shaft. A take-up shaft is symmetrically installed on the installation base, and a take-up roller is fixedly installed on the take-up shaft. One end of one take-up shaft is connected to the output end of a take-up motor. Pulleys are symmetrically fixedly installed on one end of each of the two take-up shafts, and a transmission belt is sleeved between the two pulleys. Therefore, when the user starts the take-up motor through the control panel to drive one take-up shaft to rotate, the two take-up shafts can drive the two take-up rollers to rotate synchronously and in the same direction. On the other hand, vertical plates are symmetrically fixedly installed on the installation base. Rolling grooves are symmetrically opened on the side walls of the two vertical plates on opposite sides. A take-up sleeve can be fixedly sleeved on the rolling shaft. In use, the worker can fix one end of the plastic film product to the take-up sleeve, and then insert the two ends of the rolling shaft into the corresponding rolling grooves. At this time, the bottom surface of the take-up sleeve can abut between the two take-up rollers. Starting the take-up motor drives the take-up shaft to rotate, which in turn drives the take-up sleeve and the rolling shaft to rotate within the rolling grooves. Thus, the rotating take-up sleeve is used to process the plastic film material. As the plastic film material is wound up, the increasingly larger diameter roll lifts the winding sleeve and causes the rolling shaft to move upwards along the rolling groove. The weight of the plastic film material itself ensures that the wound material is tight and does not easily loosen. Once the desired diameter roll is reached, the rolled film roll can be easily removed by simply taking the rolling shaft and winding sleeve out of the rolling groove, thus improving work efficiency. Furthermore, a ratchet is fixedly installed at one end of one winding shaft, and the installation... A fixed block is fixedly installed on the side wall of the base, and a rotating shaft is installed on the side wall of the base. A movable plate is installed on the rotating shaft. A pawl is fixedly installed on one side of the movable block, and several springs are installed between the bottom surface of the movable block and the top surface of the fixed block. Therefore, when the take-up shaft rotates in the forward direction, the ratchet rotates accordingly and continuously presses down the pawl and the movable block. When the take-up shaft wants to reverse, the ratchet and pawl engage with each other to prevent the take-up shaft from reversing. This can effectively prevent the plastic film roll from loosening due to the take-up shaft reversing, making it more practical.

[0017] (2) This utility model is equipped with a correction limiting plate. A mounting frame is symmetrically fixedly installed on one side of the top surface of the mounting base, and a two-way screw is installed on the mounting frame. An adjusting hand crank is fixedly installed at one end of the two-way screw. A guide slide is fixedly installed between the two mounting frames. A correction limiting plate is symmetrically arranged between the two mounting frames. A screw sleeve is symmetrically fixedly installed on the two correction limiting plates, and the screw sleeve cooperates with the two-way screw. A guide slide is symmetrically fixedly installed on the two correction limiting plates, and a guide slide rod is sleeved inside the guide slide. Before use, the user can drive the two-way screw to rotate by adjusting the hand crank, so that the two correction limiting plates move relative to each other along the direction of the guide slide rod, so that the distance between the two correction limiting plates is equal to the length of the winding sleeve. Thus, during the winding process of the plastic film material, the two correction limiting plates are used to limit the two ends of the plastic film roll, preventing the plastic film from being misaligned or shifted during the winding process, ensuring that the plastic film material is wound neatly, which is convenient for subsequent packaging and has stronger practicality.

[0028] According to an embodiment of the present invention, a plastic film winding device with anti-reverse function is provided.

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-6 As shown, an anti-reverse plastic film winding device according to an embodiment of the present invention includes a mounting base 1 and a rolling shaft 9. Winding shafts 6 are symmetrically mounted on the mounting base 1, and winding rollers 5 are fixedly mounted on the winding shafts 6. One end of one winding shaft 6 is connected to the output end of a winding motor 8. Pulleys 11 are symmetrically fixedly mounted on one end of both winding shafts 6, and a transmission belt 17 is sleeved between the two pulleys 11. Vertical plate frames 2 are symmetrically fixedly mounted on the mounting base 1. Rolling grooves 10 are symmetrically opened on the sidewalls of the two vertical plate frames 2 on opposite sides. A winding sleeve 3 is fixedly sleeved on the rolling shaft 9. The two ends of the rolling shaft 9 are embedded in the rolling groove 10. A ratchet 16 is fixedly installed at one end of the winding shaft 6 on one side. A fixing block 20 is fixedly installed on the side wall of the mounting base 1, and a rotating shaft 22 is installed on the side wall of the mounting base 1. A movable plate is installed on the rotating shaft 22. A pawl 24 is fixedly installed on one side of the movable block 23. Several springs 21 are connected between the bottom surface of the movable block 23 and the top surface of the fixing block 20. This effectively prevents the winding shaft 6 from reversing and causing the plastic film roll to loosen. It also facilitates the removal and disassembly of the wound plastic film roll, improving work efficiency and making it more practical.

[0030] In one embodiment, mounting brackets 12 are symmetrically fixedly mounted on one side of the top surface of the mounting base 1, and bidirectional lead screws 14 are mounted on the mounting brackets 12. Guide slide rods 4 are fixedly mounted between the two mounting brackets 12. Correction limiting plates 15 are symmetrically arranged between the two mounting brackets 12. Lead screw sleeves 19 are symmetrically fixedly mounted on the two correction limiting plates 15, and the lead screw sleeves 19 cooperate with the bidirectional lead screws 14. Guide slide sleeves 18 are symmetrically fixedly mounted on the two correction limiting plates 15, and guide slide rods 4 are sleeved inside the guide slide sleeves 18. This achieves the function of limiting the two ends of the plastic film roll by using the two correction limiting plates 15, preventing the plastic film from being misaligned or shifted during the winding process, ensuring that the plastic film material is wound neatly, facilitating subsequent packaging, and making it more practical.

[0031] In one embodiment, a control panel 7 is fixedly installed on the side wall of the mounting base 1, and the control panel 7 is electrically connected to the winding motor 8. The control circuit of the control panel 7 can be implemented by simple programming by those skilled in the art, which is common knowledge in the art. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0032] In one embodiment, an adjusting hand crank 13 is fixedly installed at one end of the bidirectional lead screw 14, which facilitates the adjustment and rotation of the bidirectional lead screw 14.

[0033] In one embodiment, the width of the rolling groove 10 is greater than the diameter of the rolling shaft 9.

[0034] In one embodiment, the rolling shaft 9 and the take-up shaft 6 are parallel to each other.

[0035] In one embodiment, the centerlines of the two take-up spools 6 are on the same horizontal plane.

[0036] Working Principle: This utility model is equipped with a mounting base 1 and a rolling shaft 9. A take-up shaft 6 is symmetrically mounted on the mounting base 1, and a take-up roller 5 is fixedly mounted on the take-up shaft 6. One end of one take-up shaft 6 is connected to the output end of a take-up motor 8. Pulleys 11 are symmetrically fixedly mounted on one end of both take-up shafts 6, and a transmission belt 17 is sleeved between the two pulleys 11. Therefore, when the user starts the take-up motor 8 via the control panel 7 to drive one take-up shaft 6, both take-up shafts 6 will drive the two take-up rollers 5 to rotate synchronously and in the same direction. On the other hand, vertical plate frames 2 are symmetrically fixedly mounted on the mounting base 1. Rolling grooves 10 are symmetrically opened on the side walls of the two vertical plate frames 2 opposite to each other. A take-up sleeve 3 can be fixedly sleeved on the rolling shaft 9, allowing... During operation, the worker can fix one end of the processed plastic film product onto the take-up sleeve 3, and then engage the two ends of the rolling shaft 9 with corresponding parts in the rolling groove 10. At this time, the bottom surface of the take-up sleeve 3 can abut between the two take-up rollers 5. Then, start the take-up motor to drive the take-up shaft 6 to rotate, which will drive the take-up sleeve 3 and the rolling shaft 9 to rotate within the rolling groove 10. Thus, the rotating take-up sleeve 3 can be used to take up the plastic film material. As the plastic film material is taken up, the plastic film roll with an increasingly larger diameter will lift the take-up sleeve 3 and cause the rolling shaft 9 to move upward along the rolling groove 10. Under the action of the plastic film roll material's own weight, the taken-up plastic film material can be kept tight and not easily loosened. After taking up the plastic film roll to the required diameter, the worker only needs to remove the rolling shaft 9 and the take-up sleeve 3 from the rolling groove 10. The film roll can be removed from the slot 10, thus completing the unwinding and disassembly of the wound plastic film roll, improving work efficiency. On the other hand, a ratchet 16 is fixedly installed at one end of the winding shaft 6, and a fixing block 20 is fixedly installed on the side wall of the mounting base 1. A rotating shaft 22 is installed on the side wall of the mounting base 1, and a movable plate is installed on the rotating shaft 22. A pawl 24 is fixedly installed on one side of the movable block 23, and several springs 21 are connected between the bottom surface of the movable block 23 and the top surface of the fixing block 20. Therefore, when the winding shaft 6 rotates forward, the ratchet 16 rotates accordingly and continuously presses down the pawl 24 and the movable block 23. When the winding shaft 6 wants to reverse, the ratchet 16 and the pawl 24 engage with each other to prevent the winding shaft 6 from reversing, which can effectively prevent the winding shaft 6 from reversing. This design allows the plastic film roll to loosen, improving its practicality. Additionally, this invention includes a correction limiting plate 15. A mounting bracket 12 is symmetrically fixed to one side of the top surface of the mounting base 1, and a bidirectional lead screw 14 is mounted on the mounting bracket 12. One end of the bidirectional lead screw 14 is fixedly mounted with an adjusting hand crank 13. A guide slide rod 4 is fixedly mounted between the two mounting brackets 12. Correction limiting plates 15 are symmetrically arranged between the two mounting brackets 12, and lead screw sleeves 19 are symmetrically fixed to the two correction limiting plates 15, cooperating with the bidirectional lead screw 14. Guide slide sleeves 18 are symmetrically fixed to the two correction limiting plates 15, and the guide slide rod 4 is fitted inside the guide slide sleeves 18. Before use, the user can rotate the bidirectional lead screw 14 by adjusting the hand crank 13.This causes the two correction limiting plates 15 to move relative to each other along the guide slide rod 4, making the distance between the two correction limiting plates 15 equal to the length of the winding sleeve 3. Thus, during the winding process of the plastic film material, the two correction limiting plates 15 limit the ends of the plastic film roll, preventing misalignment and displacement of the plastic film during winding. This ensures neat winding of the plastic film material, facilitating subsequent packaging and enhancing its practicality.
