Description

Technical Field

[0001] This utility model relates to the field of stretch film curing technology, specifically a residue removal mechanism in a stretch film curing oven. Background Technology

[0002] Stretch film, also known as stretch film or heat shrink film, was first produced in China using PVC as the base material and DOA as a plasticizer that also acts as a self-adhesive. However, due to environmental concerns, high cost (relatively higher density than PE, resulting in smaller unit packaging area), and poor tensile strength, it was gradually phased out when PE stretch film began to be produced in China in 1994-1995. During the curing process of stretch film, glue or paint is applied on a coating machine beforehand, and then it is dried in a curing oven at a temperature of 25-40°C to complete the entire coating process.

[0003] Currently, the micro-protruding particles generated during coating in the coating machine scatter onto the stretch film after being scraped by the scraping mechanism in the drying oven. Due to the lack of a cleaning mechanism, the stretch film is prone to moisture reabsorption after leaving the drying oven, causing the particles to re-adhere to the stretch film, making subsequent cleaning inconvenient and affecting the quality of the stretch film. To address this, we have proposed a residue removal mechanism for the stretch film curing oven. Utility Model Content

[0004] The purpose of this invention is to provide a residue removal mechanism in a stretch film curing oven, in order to solve the problem mentioned in the background art that the current curing ovens lack a cleaning mechanism, which makes it easy for the stretch film to become damp after leaving the oven, causing particles to re-adhere to the stretch film, thus making subsequent cleaning inconvenient and affecting the quality of the stretch film.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a residue removal mechanism for a wrapping film curing oven, comprising a shell, a door, a first support, a second support, a mounting bracket, a heating bracket, a cleaning assembly, and a connecting assembly.

A mounting groove extends through the middle of the top of the front and rear sides of the first support, and a feeding roller is placed inside the mounting groove. The top of the front side of the second support... A drive motor is fixedly connected. A rotating shaft is rotatably connected through the top of the front and rear sides of the second bracket. A receiving roller is connected between the opposite ends of the rotating shafts at the front and rear sides through the connecting assembly. A guide roller is rotatably connected through the top of the front and rear sides of the inner side of the mounting frame. The cleaning assembly includes a fixed plate, a sliding rod, a slider, a connecting frame, a cleaning brush, a connecting rod, a rotating motor, and a turntable.

[0008] As a further description of the above technical solution:

[0009] The input end of the drive motor is electrically connected to the output end of the external power supply, and the output shaft end of the drive motor is fixedly connected to the front end of the front rotating shaft.

[0011] The other end of the connecting rod is rotatably connected to the top edge of the turntable, and the input end of the rotating motor is electrically connected to the output end of an external power source.

[0012] As a further description of the above technical solution:

[0013] The connecting assembly includes a connecting frame, a slot, a connecting block, a shrinkage cavity, a return spring, a connecting plate, and a locking block.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The residue removal mechanism in the stretch film curing oven, through the starting of the rotating motor, drives the turntable to rotate, thereby causing the front end of the connecting rod to make a circular motion on the edge of the turntable. This causes the connecting rod to drive the slider to move back and forth on the outside of the slider, and to drive the connecting frame to move back and forth. This allows the cleaning brush to clean the upper and lower sides of the stretch film, preventing particle residue from scattering on the stretch film. This also prevents the stretch film from becoming damp after leaving the oven, causing particles to re-adhere to the stretch film, thus avoiding affecting the quality of the stretch film and improving the processing quality.

[0018] 2. The residue removal mechanism in the stretch film curing oven allows the take-up roller to be disassembled by pressing the locking block, which then retracts into the slot and releases the fixing of the connecting block. A new take-up roller can then be installed. Pressing the locking block again causes it to retract into the shrinkage chamber, compressing the return spring. The connecting block is then placed inside the connecting frame. When the locking block aligns with the slot, the return spring resets the locking block, allowing it to be embedded in the slot, thus completing the installation. This facilitates the replacement of the take-up roller, makes it easier to retrieve the finished product, saves time, and enhances the practicality of the device. Attached Figure Description

Please refer to [link to relevant documentation]. Figure 1-4 It includes a housing 100, a door 200, a first bracket 300, a second bracket 400, a mounting bracket 500, a heating bracket 600, a cleaning assembly 700, and a connecting assembly 800;

[0028] Please refer to it again. Figure 1 The outer casing 100 is used to install the door 200, the first bracket 300, the second bracket 400, the mounting bracket 500, the heating bracket 600, the cleaning assembly 700, and the connecting assembly 800;

[0029] Please refer to it again. Figure 1 The door 200 is hinged to the left and right sides of the front of the outer shell 100. The first bracket 300 is fixedly connected to the left side of the bottom of the inner cavity of the outer shell 100. The second bracket 400 is fixedly connected to the right side of the bottom of the inner cavity of the outer shell 100. The mounting bracket 500 is symmetrically fixedly connected to the left and right sides of the bottom of the outer shell 100. The heating bracket 600 is fixedly connected to the middle of the bottom of the inner cavity of the outer shell 100. The cleaning assembly 700 is connected to the right side of the bottom of the inner cavity of the outer shell 100 and is located between the heating bracket 600 and the right mounting bracket 500. Between 00, the first bracket 300 has a mounting groove 310 running through the middle of the top of the front and rear sides, and a feeding roller 320 is placed inside the mounting groove 310. The top of the front side of the second bracket 400 is fixedly connected to a drive motor 410. The top of the front and rear sides of the second bracket 400 is rotatably connected to a rotating shaft 420. The opposite ends of the rotating shaft 420 at the front and rear sides are connected to a receiving roller 430 through a connecting assembly 800. The top of the front and rear sides of the inner side of the mounting frame 500 is rotatably connected to a guide roller 510.

[0030] Please refer to it again. Figure 3 The cleaning assembly 700 includes a fixed plate 710, a slide bar 720, a slider 730, a connecting frame 740, a cleaning brush 750, a connecting rod 760, a rotating motor 770, and a turntable 780.

[0031] Please refer to it again. Figure 3A fixing plate 710 is fixedly connected to the front and rear parts of the bottom right part of the outer shell 100. A slide rod 720 is fixedly connected to the top between the opposite sides of the fixing plates 710. A slider 730 is slidably connected to the outer side wall of the slide rod 720. A connecting frame 740 is fixedly connected to the bottom of the slider 730.

[0032] Please refer to it again. Figure 3 A cleaning brush 750 is fixedly connected to the middle of the upper and lower sides of the inner cavity of the connecting frame 740. A connecting rod 760 is rotatably connected to the top of the slider 730. A rotating motor 770 is fixedly connected to the top of the front side of the front fixing plate 710. A turntable 780 is fixedly connected to the end of the output shaft of the rotating motor 770.

[0033] In summary, by starting the rotating motor 770, the turntable 780 is driven to rotate, causing the front end of the connecting rod 760 to make a circular motion on the edge of the turntable 780. This causes the connecting rod 760 to drive the slider 730 to move back and forth on the outside of the slider 720, which in turn causes the connecting frame 740 to move back and forth. This allows the cleaning brush 750 to clean the upper and lower sides of the stretch film, preventing particle residue from scattering on the stretch film and preventing the stretch film from becoming damp after leaving the oven, which would cause particles to re-adhere to the stretch film, thus avoiding affecting the quality of the stretch film and improving the processing quality.

[0034] Please refer to it again. Figure 2 The mounting bracket 500 is located between the first bracket 300 and the second bracket 400, and the heating bracket 600 is located between the left and right mounting brackets 500.

[0035] Please refer to it again. Figure 4 The input terminal of the drive motor 410 is electrically connected to the output terminal of the external power supply, and the output shaft end of the drive motor 410 is fixedly connected to the front end of the front rotating shaft 420.

[0036] Please refer to it again. Figure 3 The other end of the connecting rod 760 is rotatably connected to the top edge of the turntable 780, and the input end of the rotating motor 770 is electrically connected to the output end of the external power supply.

[0037] Please refer to it again. Figure 4The connecting assembly 800 includes a connecting frame 810, a slot 820, a connecting block 830, a shrinkage cavity 840, a return spring 850, a connecting plate 860, and a locking block 870. The connecting frame 810 is fixedly connected to the opposite ends of the front and rear rotating shafts 420. The slot 820 is opened through the middle of the left and right sides inside the connecting frame 810. The connecting block 830 is fixedly connected to the middle of the front and rear sides of the receiving roller 430. The shrinkage cavity 840 is opened in the middle of the left and right sides of the connecting block 830. The return spring 850 is fixedly connected to the middle of the adjacent sides of the left and right shrinkage cavities 840. The connecting plate 860 is fixedly connected to the opposite ends of the left and right return springs 850. The locking block 870 is fixedly connected to the middle of the opposite sides of the left and right connecting plates 860.

[0038] Please refer to it again. Figure 4 The connecting block 830 is slidably connected to the inside of the contraction cavity 840, and the outer side wall of the connecting block 830 is in contact with the inner side wall of the contraction cavity 840.

[0039] In summary, by pressing the locking block 870, the locking block 870 is disengaged from the slot 820, releasing the fixing of the connecting block 830, thereby disassembling the take-up roller 430. Then, a new take-up roller 430 is installed. Pressing the locking block 870 again causes it to retract into the shrinkage cavity 840, compressing the return spring 850. The connecting block 830 is then placed inside the connecting frame 810. When the locking block 870 is aligned with the slot 820, the return spring 850 resets the locking block 870, causing it to embed itself in the slot 820, completing the installation. This facilitates the replacement of the take-up roller 430, makes it easier to retrieve the finished product, saves time, and improves the practicality of the device.

[0040] In practical use, those skilled in the art will have the drive shaft of the feeding roller 320 embedded in the mounting groove 310, positioning the feeding roller 320 on the first bracket 300. Then, the stretch film is placed on the heating frame 600, passing through the cleaning brush 750 and winding onto the take-up roller 430. The drive motor 410, heating frame 600, and rotation motor 770 are then started. Starting the drive motor 410 causes the rotating shaft 420 to rotate the take-up roller 430, winding the stretch film. The heating frame 600 heats and cures the stretch film. Starting the rotation motor 770 causes the turntable 780 to rotate, causing the front end of the connecting rod 760 to move in a circular motion around the edge of the turntable 780. This, in turn, causes the connecting rod 760 to move the slider 730... The sliding rod 720 moves back and forth on its outer side, causing the connecting frame 740 to move back and forth, so that the cleaning brush 750 cleans the upper and lower sides of the stretch film, preventing particle residue from scattering on the stretch film. After processing, the locking block 870 is pressed to remove the locking block 870 from the slot 820, releasing the fixing of the connecting block 830, thereby disassembling the take-up roller 430 and removing the processed stretch film. Then, a new take-up roller 430 is installed. The locking block 870 is pressed to retract into the shrinkage cavity 840, squeezing the return spring 850. Then, the connecting block 830 is placed inside the connecting frame 810. When the locking block 870 is aligned with the slot 820, the return spring 850 resets the locking block 870, causing it to be embedded in the slot 820, completing the installation.
