Description

TECHNICAL FIELD

[0001] The application relates to the production technology of preservative film, in particular to a winding machine for degradable preservative film. BACKGROUND

[0002] As an innovative packaging material emerging in the environmental protection trend in recent years, the degradable preservative film is gradually replacing the traditional plastic preservative film and becoming a new darling in the food packaging field. The core advantage of the degradable preservative film lies in that the biodegradable materials such as chitosan are adopted, the materials are derived from nature and can be gradually decomposed under the action of microorganisms under specific environmental conditions, and finally return to nature circulation. The preservative film not only has good degradability, but also has excellent ductility, flexibility and transparency, and is widely used in the field of food packaging.

[0003] In the related art, in the production process of the degradable preservative film, the winding machine as the key equipment connecting the end of the production line plays a vital role. However, the existing winding machine is prone to wrinkles in the winding process, which affects the flatness of the preservative film. The wrinkled preservative film not only affects the appearance, but also may reduce the quality of the wound preservative film and affect the preservation effect during subsequent use. Therefore, it needs to be improved. CONTENT OF THE INVENTION

[0004] In order to solve the problem that the preservative film is prone to wrinkles in the winding process, the application provides a winding machine for degradable preservative film.

[0005] The winding machine for degradable preservative film provided by the application adopts the following technical scheme:

[0006] A winding machine for degradable preservative film, comprising a rack, a winding roller rotatably arranged on the rack, a winding disc arranged on the winding roller, and two groups of tensioning roller groups rotatably arranged on the rack. The two groups of tensioning roller groups are sequentially arranged on the rack, and a flattening mechanism for preventing wrinkles is arranged between the two groups of tensioning roller groups. The flattening mechanism comprises two flattening rods, two flattening blocks and two flattening clamps. The two flattening rods, the two flattening blocks and the two flattening clamps are one-to-one corresponding. The two flattening rods are arranged between the two groups of tensioning roller groups, and the two flattening rods are connected to the rack. The flattening block is connected to the flattening rod, and the flattening clamp is connected to the flattening block. A flattening groove is formed in any one of the flattening clamps for the preservative film to pass through.

[0007] Since the existing winding machine is prone to wrinkles during winding, affecting the flatness of the cling film, the wrinkled cling film not only affects the appearance, but also may reduce the quality of the wound cling film, affecting the preservation effect during subsequent use; by adopting the above technical scheme, the frame, the winding disc is installed on the frame through the winding roller, the two groups of tensioning roller groups are installed on the frame, the flattening mechanism is located between the two groups of tensioning roller groups, the flattening mechanism includes two flattening rods, two flattening blocks and two flattening clamps;

[0008] When winding the cling film, one end of the cling film to be wound is fixed on the winding disc of the winding roller to ensure that the cling film can be smoothly unfolded, the driving device (such as a motor) of the winding machine is started to make the winding roller start rotating, thereby driving the winding disc to start winding the cling film, and the two groups of tensioning roller groups also start working, which preliminarily stretch and flatten the cling film, and the cling film maintains a certain tension and flatness during winding. When the cling film passes between the two groups of tensioning roller groups, it will enter the flattening mechanism, and the cling film will pass through the flattening grooves on the flattening clamps. During this process, the flattening blocks and the flattening clamps further flatten the cling film to eliminate small wrinkles on the cling film and make it more flat. The cling film after flattening treatment will continue to move forward and eventually be wound onto the winding disc of the winding roller. With the continuous rotation of the winding roller, the cling film will be gradually tightly wound on the winding disc to form a neat and beautiful cling film roll. Through the setting of the flattening mechanism, the cling film is effectively flattened to eliminate small wrinkles and improve the flatness of the cling film, which not only improves the appearance of the cling film, but also ensures its preservation effect during subsequent use. The wound cling film roll is more neat and tight, improving the winding quality without manual intervention, and the production efficiency is high.

[0009] Optionally, a through hole is formed through each flattening block, the through hole of the flattening block is matched with the corresponding flattening rod, the flattening block is slidingly connected to the flattening rod, and a knob for fixing the flattening block to the flattening rod is arranged on the flattening block.

[0010] Through the above technical scheme, the flattening block slides on the flattening rod through the through hole, and the flattening block is fixed to the flattening rod through the knob. Through the setting of the through hole and the knob, the flattening block is slidingly connected to the flattening rod through the through hole, which means that the position of the flattening block can be adjusted as needed to flexibly adjust the contact position and pressure between the flattening block and the cling film, thereby optimizing the flattening effect. At the same time, the knob is used to fix the flattening block to the desired position on the flattening rod to ensure that the flattening block does not move due to vibration or external force during winding, thereby maintaining stable flattening effect.

[0011] Optionally, an anti-dropping part for limiting is arranged at the end of each flattening rod away from the frame.

[0012] By adopting the technical scheme, the anti-disengagement part is integrally formed at the end of the flattening rod; through the arrangement of the anti-disengagement part, the flattening block is effectively prevented from being accidentally disengaged from the flattening rod due to external force or vibration during sliding, thereby ensuring the stability and reliability of the flattening mechanism and improving the safety of the equipment.

[0013] Optionally, sliding grooves are formed in the rack, and sliding blocks are arranged on the two flattening rods and are respectively slidably connected in the sliding grooves.

[0014] By adopting the technical scheme, the flattening block slides in the sliding groove through the sliding block; through the arrangement of the sliding groove and the sliding block, the combination of the sliding groove and the sliding block allows the flattening rod to smoothly and stably slide on the rack, so that the position of the flattening rod can be easily adjusted by the operator to adapt to the fresh-keeping film of different widths or thicknesses, thereby ensuring the best flattening effect.

[0015] Optionally, a driving assembly for driving the flattening clamping plate to move is arranged in the sliding groove of the rack, the driving assembly comprises a servo motor and a bidirectional screw rod, the bidirectional screw rod is rotatably connected in the sliding groove, the servo motor is connected to the rack, the output end of the servo motor is connected to the end of the bidirectional screw rod, and the two sliding blocks are respectively threadedly connected to the two threaded segments of the bidirectional screw rod.

[0016] By adopting the technical scheme, the driving assembly is installed on the rack, and the driving assembly comprises a servo motor and a bidirectional screw rod; when the flattening mechanism is adjusted, the position to which the flattening mechanism needs to be adjusted is determined according to the specifications (such as width, thickness, etc.) of the fresh-keeping film to be wound, the servo motor is started, the output end of the servo motor starts to rotate, drives the bidirectional screw rod connected thereto to rotate, and the two threaded segments on the bidirectional screw rod drive the two sliding blocks to move closer to or away from each other in the sliding groove, and the movement of the sliding blocks drives the flattening rod and the flattening block and the flattening clamping plate connected to the flattening rod to move together to adapt to different fresh-keeping films; through the arrangement of the driving assembly, automatic operation can be performed, the complexity of manual operation is reduced, the rotation angle and speed of the bidirectional screw rod can be accurately controlled, the accurate adjustment of the flattening mechanism is realized, and the winding quality is improved.

[0017] Optionally, an outer baffle for positioning is arranged on the rack, the winding roller penetrates through the outer baffle, and one end of the winding disc abuts against the outer baffle.

[0018] By adopting the technical scheme, the outer baffle is installed on the rack; through the arrangement of the outer baffle, the winding disc can be positioned to prevent it from deviating or shaking during winding, and foreign objects or impurities can be prevented from entering the winding area to protect the winding mechanism and the fresh-keeping film from being damaged.

[0019] Optionally, a sleeve ring is arranged on the winding roller for fixation, and the sleeve ring is arranged at the end of the winding disc away from the outer baffle.

[0020] By adopting the above technical scheme, the sleeve ring is installed on the winding roller. Through the arrangement of the sleeve ring, the sleeve ring can be fixed firmly on the winding roller, so that the winding disc cannot fall off or shift during the winding process due to rotation or external force, and the stable and reliable installation of the winding disc is ensured.

[0021] Optionally, a slot is arranged on the winding roller along the length direction of the winding roller, and a latch is arranged on the sleeve ring and penetrates through the sleeve ring and is connected in the slot.

[0022] By adopting the above technical scheme, the slot is arranged on the winding roller, and the sleeve ring is fixed in the slot through the latch. Through the arrangement of the latch and the slot, the close cooperation of the latch and the slot ensures the firm fixation of the sleeve ring on the winding roller, and the sleeve ring is not easy to loosen or fall off. At the same time, the installation and disassembly are simple and fast, the operation time is greatly saved, and the work efficiency is improved.

[0023] In summary, the present application has at least one of the following beneficial technical effects:

[0024] Through the arrangement of the flattening mechanism, the cling film is effectively flattened, the micro wrinkles are eliminated, the flatness of the cling film is improved, the appearance of the cling film is improved, the preservation effect of the cling film in subsequent use is ensured, the cling film roll after winding is more neat and compact, the winding quality is improved, manual intervention is not needed, and the production efficiency is high.
