TECHNICAL FIELD
[0001] The application relates to the technical field of film production, in particular to a plastic film production edge collecting device. BACKGROUND
[0002] In the plastic film manufacturing industry, the edge collecting process is a key link to guarantee product quality and appearance, and its technical level directly affects the market competitiveness of products and the production efficiency of enterprises. With the development of the industry and the diversification of market demand, the plastic film production edge collecting technology has undergone several iterations, gradually moving from simple manual operation in the early stage to automation and intelligence;
[0003] The existing plastic film edge collecting device, when in use, the cutting knife rotating at high speed contacts the plastic film, and under the action of strong shearing force, the edge of the plastic film is precisely cut, and the debris generated is separated from the cutting part due to the impact force of the cutting moment and its own gravity. At this time, the first deceleration motor is started to transmit power to the conveying roller to drive the conveying belt to continuously run. The debris falls vertically to the conveying belt running below under the action of gravity, and is smoothly transported to the collection box below the right conveying roller with the movement of the conveying belt, to complete the edge collecting and debris collecting of the plastic film;
[0004] However, the plastic film debris is light in quality, irregular in shape and large in surface area, and is easily affected by air flow in the collection box. The cutting knife rotating at high speed in the cutting device and the running motor form a local turbulent air flow around them, and the air flow blown by the fan of the auxiliary device circulates in the cutting box. The two interfere with each other to form a complex air flow field in the collection box. Due to the physical properties of the debris, the buoyancy generated by the air flow on the debris cannot be ignored. When the buoyancy is close to or exceeds the gravity, the debris will float. At the same time, the friction between the conveying belt and the debris when the conveying belt is running will generate an upward component force under certain conditions, aggravating the floating phenomenon of the debris. At the same time, the floating of the debris makes the collection process unstable, and part of the debris that should fall into the collection box cannot reach the collection box smoothly due to the floating effect, but is scattered outside the collection box or other positions of the equipment. This reduces the collection efficiency and cannot fully realize the automatic collection function of the cut debris. Therefore, it is necessary to provide a plastic film production edge collecting device to solve the above problems.

[0028] It should be noted that the embodiments in the application and the features in the embodiments can be combined with each other without conflict. The application will be described in detail below with reference to the drawings and in combination with the embodiments.
[0029] In order for the person skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described in the following with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the scope of protection of the present application.
[0030] As shown in Figures 1-6 The present application provides a plastic film production edge collecting device, which comprises a conveying assembly 1, the conveying assembly 1 comprising a cutting box 11, the cutting box 11 having opening grooves 13 on both sides for the plastic film to pass through, and a viewing window 12 being installed on the cutting box 11 in communication, the cutting box 11 being convenient for the user to view the working condition inside the cutting box 11;
[0031] and a cleaning assembly 2 being installed in the conveying assembly 1, the cleaning assembly 2 comprising two groups of support units being fixedly installed in the conveying assembly 1, the support unit on the left side being defined as a first support unit, and the support unit on the right side being defined as a second support unit (refer to Figure 5 ), the two groups of support units having a certain distance therebetween, and the support unit comprising mounting plates 21 being fixedly installed at both ends of the inner wall of the conveying assembly 1, and first bearing seats 22 being fixedly installed on the upper surface of the mounting plates 21, the two groups of first bearing seats 22 being rotatably provided with auxiliary rollers 23, the auxiliary rollers 23 having roller shafts, and the auxiliary rollers 23 being adapted to support the plastic film;
[0032] Meanwhile, a first motor 24 is fixedly installed on the outer surface of the cutting box 11, the output end of the first motor 24 penetrating the cutting box 11, and the output end of the first motor 24 being fixedly connected with the roller shaft of the second support unit, and meanwhile, a first pulley 25 being fixedly installed on the roller shaft of the second support unit, and a second pulley 26 being fixedly installed on the roller shaft of the first support unit, the first pulley 25 and the second pulley 26 being connected with a first belt body therebetween;
[0033] When the cleaning assembly 2 is working, the first motor 24 is started, and the output end of the first motor 24 drives the roller shaft of the second support unit fixedly connected therewith to rotate. Since the first pulley 25 is fixedly installed on the roller shaft of the second support unit, and the second pulley 26 is fixedly installed on the roller shaft of the first support unit, and the two are connected through the first belt body, according to the principle of belt transmission, the rotation of the first pulley 25 will drive the second pulley 26 to rotate through the first belt body, and then the roller shaft of the first support unit is rotated. The synchronous rotation of the two roller shafts drives the two groups of auxiliary rollers 23 located in the two groups of support units to rotate, and the roller shaft of the auxiliary roller 23 rotates smoothly in the first bearing seat 22, so as to realize the stable support and conveying of the plastic film, and guarantee the orderly performance of the subsequent edge collecting process
[0034] And the lower surface of the mounting plate 21 of the second support unit is fixedly installed with a second bearing seat 27, and a cleaning brush 28 is installed and connected between the two groups of second bearing seats 27, which is in contact with the surface of the auxiliary roller 23 of the second support unit;
[0035] In the device, when the first motor 24 drives the auxiliary roller 23 of the second support unit to rotate, the cleaning brush 28 is installed on the lower surface of the mounting plate 21 of the second support unit and is in contact with the surface of the auxiliary roller 23. During the rotation of the auxiliary roller 23, the surface thereof moves relative to the cleaning brush 28. Based on the friction force, the cleaning brush 28 can clean the surface of the auxiliary roller 23. During the production of plastic film, the surface of the auxiliary roller 23 may be adhered with debris, impurities and the like of the plastic film when supporting the plastic film. The continuous operation of the cleaning brush 28 can timely remove these adhered matters, ensure the cleanliness of the surface of the auxiliary roller 23, maintain the stable supporting and conveying effect of the plastic film, avoid the influence of surface impurities on the flatness and production quality of the plastic film, and ensure the stable and efficient operation of the edge collecting device;
[0036] And two groups of cutting assemblies 3 are installed on the inner wall top end of the cutting box 11, the cutting assemblies 3 are a certain distance apart, and the cutting assembly 3 comprises a sliding rail 31 fixedly installed on the inner wall top end of the cutting box 11, the sliding rail 31 has a T-shaped sliding groove 32, a sliding block 39 is slidably installed in the T-shaped sliding groove 32, and a bolt 33 is connected between the sliding block 39 and the sliding rail 31, the bolt 33 is used to fix the sliding block 39 at a certain position in the T-shaped sliding groove 32, thereby indirectly adjusting the distance between the sliding blocks 39 of the two groups of cutting assemblies 3;
[0037] The sliding block 39 has a through side slot, a gas cylinder 34 is fixedly installed in the side slot, the output end of the gas cylinder 34 penetrates the sliding block 39, a lifting plate 35 is fixedly installed on the output end of the gas cylinder 34, the lifting plate 35 is adapted to move up and down with the output end of the gas cylinder 34, and four guide columns 36 are fixedly installed on the lifting plate 35, the guide columns 36 are adapted to limit the moving direction of the lifting plate 35;
[0038] And a second motor 37 is fixedly installed on one side of the lifting plate 35 away from the gas cylinder 34, a cutting knife 38 is fixedly installed on the output end of the second motor 37, and the cutting knife 38 is adapted to rotate with the output end of the second motor 37 to perform a flash operation on the plastic film. It should be noted that the cutting knives 38 of the two groups of cutting assemblies 3 are oppositely arranged, and the cutting knives 38 are adapted to move synchronously with the movement of the sliding block 39 to adjust the distance between the two cutting knives 38 to adapt to different plastic film processing uses;
[0039] First, according to the processing requirements of different plastic film (the size is within the width of the opening slot 13), by adjusting the bolt 33, the sliding block 39 slides in the T-shaped sliding groove 32 of the sliding rail 31, so as to change the distance between the sliding blocks 39 in the two cutting assemblies 3, and then drive the entire cutting execution part mounted on the sliding block 39 to move, realize the distance adjustment between the two cutting knives 38, and adapt to the edge collection requirements of plastic film with different widths.
[0040] When the cutting work starts, the cylinder 34 is started, the output end of the cylinder 34 is extended or retracted, and the lifting plate 35 fixed thereto is driven to move up and down. In this process, the four guide columns 36 on the lifting plate 35 play a role to ensure that the lifting plate 35 can only move smoothly in the vertical direction, limit its movement direction, and ensure the stability and accuracy of the lifting process of the cutting knife 38.
[0041] At the same time, the second motor 37 is started, the output end of the second motor 37 rotates at high speed, and the cutting knife 38 fixedly installed thereon rotates at high speed. As the cylinder 34 drives the lifting plate 35 to descend, the high-speed rotating cutting knife 38 gradually approaches and contacts the plastic film. Because the cutting knives 38 of the two cutting assemblies 3 are oppositely arranged, during the descending process, the two cutting knives 38 simultaneously cut the edges of the plastic film on both sides, cut off the excess edge part of the plastic film, complete the flash operation, and thus obtain the plastic film product meeting the specification requirements;
[0042] And the dust blowing assembly 4 is installed on the inner wall of the cutting box 11 on both sides of the position of the cutting assembly 3, the dust blowing assembly 4 includes the installation box 41 fixedly installed on the inner wall of the cutting box 11 on both sides, the installation box 41 has a certain gap with the top end of the inner wall of the cutting box 11, and a plurality of first fans 42 are throughly embedded and installed on the installation box 41, the first fans 42 are inclinedly arranged, the air outlet end of the first fan 42 faces the upper surface of the plastic film, and a cover (not marked in the figure) is fixedly installed on the bottom of the installation box 41;
[0043] And a plurality of air outlet pipes 43 are fixedly installed on the cover, the plurality of air outlet pipes 43 are symmetrically distributed along the center line of the cutting box 11, at this position, the plurality of air outlet pipes 43 on the left side of the center line of the left cutting box 11 are defined as the first air outlet pipe, the plurality of air outlet pipes 43 on the left side of the center line of the right cutting box 11 are defined as the second air outlet pipe, and the first air outlet pipe and the second air outlet pipe are both inclinedly arranged relative to the bottom surface of the installation box 41, the inclination direction is consistent with the inclination direction of the first fan 42, at the same time, the air outlet positions of the first air outlet pipe and the second air outlet pipe are inclined to the inner wall of the cutting box 11 on both sides, it should be noted that the communication part of the air outlet pipe and the cover is in a horizontal state, so that the air blown out from the first fan 42 can be smoothly discharged from the first air outlet pipe and the second air outlet pipe, at the same time, the air blown out from the first fan 42 does not affect the normal conveying of the plastic film, that is, it does not affect the surface of the plastic film;
[0044] In the plastic film production edge closing operation, the cutting assembly 3 will produce certain debris when cutting the plastic film, and the blowing dust assembly 4 can effectively deal with this problem to ensure the production environment clean and product quality. Its working principle is as follows:
[0045] The installation box 41 of the blowing dust assembly 4 is stably installed on the inner wall of the cutting box 11, and a certain gap is reserved at the top end of the inner wall of the cutting box 11 to create conditions for the reasonable flow and diffusion of airflow. A plurality of first fans 42 are installed on the installation box 41, and the air outlet end of the first fan 42 is inclined to the upper surface of the plastic film. When the equipment is running, the first fan 42 is opened, and the airflow with a certain inclination angle is generated. The angle design can make the airflow accurately act on the upper surface of the plastic film.
[0046] The airflow generated by the first fan 42 enters the installation box 41 and is guided by the cover at the bottom of the installation box 41. A plurality of air outlet pipes 43 are arranged on the cover. The air outlet pipes 43 are symmetrically distributed along the center line of the cutting box 11. The first air outlet pipe and the second air outlet pipe are inclined to the bottom surface of the installation box 41, and the inclination direction is consistent with the first fan 42. The air outlet of the air outlet pipe is inclined to the inner wall of the cutting box 11. At the same time, the connection between the air outlet pipe and the cover is in a horizontal state, which ensures that the air blown out of the first fan 42 can smoothly pass through the air outlet pipe and be discharged.
[0047] The inclined airflow blown out of the first air outlet pipe and the second air outlet pipe impacts the upper surface of the plastic film at a suitable angle and force, and uses the impact force of the airflow to blow off the debris generated during the cutting process and attached to the plastic film. The inclined airflow direction makes the impurities move to the both sides of the cutting box 11, avoiding the impurities remaining to affect the product quality, and preventing the impurities from randomly drifting in the cutting box 11 to interfere with the equipment operation.
[0048] In addition, the air blown out of the first fan 42 is scientifically designed, and the angle and wind power will not affect the normal conveying of the plastic film, which not only ensures the effective cleaning of the debris, but also maintains the flatness of the plastic film surface and the stability of the production process, ensuring that the plastic film production edge closing device can stably and efficiently run;
[0049] In order to collect the dust cleaned by the cleaning brush 28 on the surface of the auxiliary roller 23 and the debris blown off from the plastic film by the air outlet pipe 43, a dust collection box 44 is arranged on the cutting box 11, and the dust collection box 44 is connected with the air outlet pipe 43. Figure 3 and Figures 5-6As shown, the inner wall bottom end of the cutting box 11 is provided with a collection assembly 5, which includes a conveying belt 51 fixedly installed at the inner wall bottom end of the cutting box 11, the conveying belt 51 has two groups of baffles 52 for shielding debris, the width of the conveying belt 51 is greater than the width of the plastic film with the maximum width that can be accommodated by the opening slot 13, and the width of the conveying belt 51 is greater than the width of the installation box 41 and the cleaning brush 28, so that the debris blown away from the plastic film by the air outlet pipe 43 and the dust cleaned by the cleaning brush 28 on the surface of the auxiliary roller 23 all fall on the conveying belt 51, which is uniformly received by the conveying belt 51;
[0050] Meanwhile, a support frame 53 is fixedly installed at the inner wall bottom end of the cutting box 11, and the support frame 53 has a supporting plate 54, and a collection box 55 for collecting debris on the conveying belt 51 is placed on the supporting plate 54, and a filter hole plate 56 is fixedly installed in the collection box 55, and the filter hole plate 56 has a certain gap with the inner wall bottom surface of the collection box 55;
[0051] And a plurality of suction units are provided through the side of the collection box 55 and below the filter hole plate 56, the suction unit includes a right-angle pipe 57 provided through the side of the collection box 55, a plurality of air outlet pipes are communicatively installed on the right-angle pipe 57, the air outlet pipes are arranged towards the filter hole plate 56, and a second fan 58 is connected to one end of the right-angle pipe 57 away from the collection box 55, the second fan 58 is composed of a rotating shaft 59 and a fan blade, and a gear 510 is fixedly installed on the rotating shaft 59, the plurality of suction units are meshed with each other through the gear 510, and here the suction unit on the right side is defined as a first suction unit (refer to Figure 5 ), it should be noted that the gear 510 and the second fan 58 have a certain gap for the rotation of the fan blade and the air flow to pass through;
[0052] In order to drive the rotation of the fan blade, so that the air outlet pipe has a certain negative pressure, so as to suck the debris falling on the filter hole plate 56 and prevent floating, as shown, Figures 5-6 The third belt pulley 514 is fixedly installed on the roller shaft of the first support unit, and the rotating shaft 511 is bearing-mounted on the cutting box 11, and the fourth belt pulley 515 is fixedly installed on one end of the rotating shaft 511, and the second belt body is connected between the fourth belt pulley 515 and the third belt pulley 514, so that the third belt pulley 514 is adapted to synchronously rotate with the rotation of the roller shaft of the first support unit, so as to drive the rotating shaft 511 to synchronously rotate;
[0053] And the first bevel gear 512 is fixedly installed at the end of the rotating shaft 511 extending into the cutting box 11, while the second bevel gear 513 is fixedly installed on the rotating shaft 59 of the first suction unit, and the second bevel gear 513 is engaged with the first bevel gear 512, while the opening and closing door 14 is hinged on one side of the cutting box 11 close to the collecting box 55, and the opening and closing door 14 is adapted to be opened to facilitate the removal of the collected debris on the collecting box 55;
[0054] In the technical solutions involved in the present application, the hole size of the filter hole plate 56 is smaller than the size of the debris to be collected, and the negative pressure suction generated by the operation of the second fan 58 is not enough to make the debris pass through the holes on the filter hole plate 56;
[0055] In the plastic film production edge collecting device, the collecting assembly 5 undertakes the key task of collecting dust and debris, ensuring the cleanliness of the production environment and the stable operation of the equipment, and its working principle is as follows:
[0056] In the plastic film edge collecting process, the dust generated by the surface cleaning of the auxiliary roller 23 by the cleaning brush 28 of the cleaning assembly 2 and the debris blown off the surface of the plastic film by the air outlet pipe 43 of the dust blowing assembly 4 will all fall off. The width of the conveying belt 51 of the collecting assembly 5 is designed to be greater than the maximum width of the plastic film that can be accommodated by the opening slot 13, and also exceeds the width of the installation box 41 and the cleaning brush 28, which ensures that the dust and debris can all fall on the conveying belt 51, which uniformly receives and conveys them.
[0057] The conveying belt 51 conveys the dust and debris to the collecting box 55 below. The collecting box 55 is fixed to the bottom end of the inner wall of the cutting box 11 by the support frame 53, and a filter hole plate 56 is installed in the box, which has a gap with the inner wall bottom surface of the collecting box 55. To prevent the debris from floating in the collecting box 55, multiple suction units are used. Each suction unit includes a right-angle pipe 57 that penetrates the side of the collecting box 55, one end of which is connected to the second fan 58, and the other end is connected to the air outlet pipe facing the filter hole plate 56. Multiple suction units are engaged with each other through the gear 510 fixed on the rotating shaft 59 of the second fan 58.
[0058] The power source driving the suction unit to operate is the auxiliary roller 23 of the first supporting unit. When the roller shaft of the first supporting unit rotates, the third belt pulley 514 fixed thereon rotates synchronously, and the fourth belt pulley 515 at one end of the rotating shaft 511 is driven to rotate through the second belt body, thereby rotating the rotating shaft 511. The first bevel gear 512 fixed at one end of the rotating shaft 511 in the cutting box 11 rotates, and the second bevel gear 513 on the rotating shaft 59 of the first suction unit is engaged, thereby driving the second fan 58 of the first suction unit to operate. Since the gears 510 are engaged with each other, the second fans 58 of all the suction units rotate synchronously, the fan blades rotate to generate negative pressure, and the debris falling on the filter hole plate 56 is sucked to the bottom of the collection box 55 through the air outlet pipe, thereby avoiding floating.
[0059] When the debris in the collection box 55 accumulates to a certain degree, the opening and closing door 14 hinged to the cutting box 11 can be opened, the collection box 55 can be conveniently taken out, the debris therein can be cleaned, the entire working cycle of the collection assembly 5 can be completed, and the cleaning and high efficiency in the plastic film production edge closing process can be continuously ensured.
