Description

Technical Field

[0001] This utility model relates to the field of BOPP film technology, and in particular to a BOPP film masterbatch recycling and discharge device. Background Technology

[0002] BOPA film is made from polyamide. Polyamide molecules contain polar amide groups, and the formation of hydrogen bonds is one of the important factors that gives polyamide its high crystallinity. It is also water-absorbing. Compared with other films, BOPA film has higher strength than PE and BOPP films, and lower cost and is more environmentally friendly than EVOH and PVDC films.

[0003] The existing circulating discharge device has certain drawbacks in use. For example, the capacity of the material is uncontrollable when guided by the spiral column, resulting in inaccurate discharge. In addition, it is necessary to hold and rotate the handle to move the lower end of the anti-leak plate upward to close the opening at the lower end of the storage funnel. Such operation steps are cumbersome and have certain drawbacks in use.

[0004] The existing patent (publication number: CN217752288U) discloses a circulating discharge device for masterbatch used in the production of BOPA film. This utility model features a material distribution and guiding mechanism, with a simple overall design and reasonable structure. When the distribution chamber containing the masterbatch moves to the baffle, it is limited by the baffle and subjected to the traction force of the conveyor belt and the partition plate during displacement. The baffle scrapes off excess masterbatch from the distribution chamber, ensuring consistent material flow and achieving precise control of the material flow. The device can also directly contact the top of the partition plate or the top of the conveyor belt via the baffle, thereby closing it off and making the device more convenient to use. Furthermore, the vertical cross-sectional shape of the hopper and the gathering plate is trapezoidal, which can gather the masterbatch entering the hopper. The addition of a sponge pad effectively reduces the damage to the masterbatch caused by contact with the gathering plate when it falls into the hopper.

[0005] To address the aforementioned issues, existing patents offer solutions. However, existing BOPP film masterbatch recycling and discharging devices are not convenient for adjusting the discharge position, resulting in reduced operational flexibility. Furthermore, due to the fixed discharge position, BOPP film masterbatch recycling and discharging devices are difficult to adapt to diverse production layout requirements. When masterbatch needs to be added to adjacent equipment, it is not convenient to directly transport it to the desired location, and manual transfer is required. This not only consumes a lot of time but also easily causes production interruptions during continuous production, greatly reducing overall production efficiency.

[0006] Therefore, a BOPP film masterbatch recycling and discharge device is proposed. Utility Model Content

[0007] The purpose of this invention is to provide a BOPP film masterbatch recycling and discharging device, which solves the problems of existing BOPP film masterbatch recycling and discharging devices, which are not convenient for adjusting the discharge position, resulting in reduced flexibility of use.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] A BOPP film masterbatch recycling and discharging device includes a feeding hopper 1, a discharging component 2 connected to the bottom of the feeding hopper 1, an adjusting component 3 fixedly connected to the rear side of the bottom of the discharging component 2, and a snap-fit ​​component 4 slidably connected to the inner wall of the adjusting component 3.

[0029] The adjustment component 3 includes an L-shaped block 301. A through hole 302 is provided on the rear side of the L-shaped block 301. A rotating groove 303 is provided on the top of the front side of the L-shaped block 301. A rotating block 304 is rotatably connected to the inner wall of the rotating groove 303. An adjustment disk 305 is fixedly connected to the top of the rotating block 304. An installation groove 306 is provided at the center of the interior of the adjustment disk 305. A drive motor 307 is fixedly connected to the inner wall of the installation groove 306. A snap-fit ​​hole 308 is provided on the surface of the adjustment disk 305. A scraper 309 is fixedly connected to the output end of the drive motor 307. The scraper 309 contacts the inner wall of the adjustment disk 305.

[0030] In this embodiment: By setting up the feed hopper 1, it can assist in guiding the pouring position of the masterbatch. Through the guidance of the feed hopper 1, the masterbatch can enter the discharge component 2. By setting up the feed component, after its start, it can discharge the masterbatch inside. Under the discharge of the feed component, the masterbatch can fall into the adjustment component 3. Under the setting of the adjustment component 3, it can receive the masterbatch discharged by the feed component, so that the masterbatch will not fall outside the desired position. By rotating the adjustment component 3, the subsequent discharge position of the masterbatch can be adjusted, thereby improving the flexibility of use. By setting up the snap-fit ​​component 4, the adjustment component 3 can be positioned, so that the adjustment component 3 will not rotate.

[0031] Specifically, such as Figure 3 As shown, the discharge assembly 2 includes a discharge box 201, which is connected to the feed hopper 1. The rear side of the bottom of the discharge box 201 is fixedly connected to the top of the rear side of the L-shaped block 301. A discharge slot 202 is opened on the front side of the discharge box 201, and a circulation wheel 203 is rotatably connected to both sides of the inner wall of the discharge slot 202.

[0032] Specifically, such as Figure 3 As shown, a positioning groove 204 is provided on the right side of the front side of the discharge box 201. A motor 205 is fixedly connected to the inner wall of the positioning groove 204. The output end of the motor 205 passes through the positioning groove 204 and the discharge slot 202, and is fixedly connected to the right side of the circulation wheel 203.

[0033] Specifically, such as Figure 3 As shown, a guide block 5 is fixedly connected to the bottom of the inner wall of the discharge box 201. The guide block 5 is inclined, and a protective pad 6 is fixedly connected to the inclined surface of the guide block 5.

[0034] In this embodiment: the discharge box 201 is designed to receive the masterbatch guided by the feed hopper 1. Then, by starting the motor 205, the motor 205, fixed by the positioning groove 204, drives the circulating wheel 203 to rotate. Under the rotation of the circulating wheel 203, the masterbatch in the discharge box 201 can be sent out through the discharge slot 202. The guide block 5 guides the masterbatch after it falls into the discharge box 201. The protective pad 6 protects the guide block 5 and prevents it from being damaged by the impact of the masterbatch falling.

[0035] Specifically, such as Figure 4 As shown, there are several snap-fit ​​holes 308, and the inner wall of the snap-fit ​​hole 308 is provided with a reinforcing pad 7 for use with it. There are several reinforcing pads 7.

[0036] Specifically, such as Figure 4As shown, the interior of the regulating disc 305 is arc-shaped, and the bottom of the regulating disc 305 is connected to the discharge hopper 8.

[0037] In this embodiment: the snap-fit ​​hole 308 is provided to assist in guiding the installation position of the reinforcing pad 7, and the reinforcing pad 7 protects the snap-fit ​​hole 308 from internal wear under long-term snap-fit. The discharge hopper 8 is provided to discharge the masterbatch received in the regulating plate 305.

[0038] Specifically, such as Figure 5 As shown, the snap-fit ​​assembly 4 includes a pull rod 401. The surface of the pull rod 401 is slidably connected to the inner wall of the through hole 302. An auxiliary spring 402 is sleeved on the surface of the pull rod 401. One end of the auxiliary spring 402 contacts the L-shaped block 301, and the other end of the auxiliary spring 402 contacts an auxiliary ring 403. The auxiliary ring 403 is fixedly connected to the surface of the pull rod 401. The front surface of the pull rod 401 snaps into the inner wall of the snap-fit ​​hole 308.

[0039] Specifically, such as Figure 5 As shown, a pull block 9 is fixedly connected to the rear side of the pull rod 401, and a rubber sleeve 10 is fixedly connected to the surface of the pull block 9. The surface of the rubber sleeve 10 is provided with several anti-slip protrusions.

[0040] In this embodiment: the pull rod 401 is designed to slide through the through hole 302. When sliding, it drives the auxiliary ring 403 to move. When the auxiliary ring 403 moves, it applies force to the auxiliary spring 402, thereby compressing the auxiliary spring 402. When the pull block 9 is released, the auxiliary ring 403 rebounds due to the rebound force of the auxiliary spring 402. The movement of the auxiliary ring 403 drives the pull rod 401 to move. After the pull rod 401 moves, it can be positioned by engaging with the locking hole 308. The reinforcing pad 7 makes the engagement between the pull rod 401 and the locking hole 308 more secure. With the rubber sleeve 10, the friction of the surface of the pull block 9 is increased, thereby preventing the pull block 9 from slipping on the hand when it is pulled.

[0041] Working principle: When the discharge position needs to be adjusted, the pull block 9 can be pulled. After the pull block 9 is pulled, the pull rod 401 can be moved. After the pull rod 401 moves, it can be disengaged from the snap-fit ​​hole 308. When the pull rod 401 moves, it can drive the auxiliary ring 403 to move. When the auxiliary ring 403 moves, it can press the auxiliary spring 402 against the L-shaped block 301, which will then rotate the adjusting disc 305. This will cause the adjusting disc 305 to drive the rotating block 304 to rotate in the rotating groove 303. With the rotating block 304 and the rotating groove 303 in rotation, the rotation position of the adjusting disc 305 will not be offset. After the adjusting disc 305 rotates to the desired position, the pull block 9 is released. The rebound force of the auxiliary spring 402 will push the auxiliary ring 403. Under the movement of the auxiliary ring 403, the pull block 9 will be adjusted. The rod 401 engages with the snap-fit ​​hole 308 to position the adjusted disc 305. When the masterbatch enters the discharge box 201, the motor 205 is started. The motor 205, fixed in the positioning groove 204, drives the circulating wheel 203 to rotate. When the circulating wheel 203 rotates, the masterbatch in the discharge box 201 is sent out through the discharge chute 202. After the masterbatch is sent out, it can be received by the adjusted disc 305. Then, the drive motor 307 is started, which, fixed in the mounting groove 306, drives the scraper 309 to rotate. When the scraper 309 rotates, it scrapes the masterbatch received in the adjusted disc 305 to the connection between the adjusted disc 305 and the discharge hopper 8. Finally, guided by the discharge hopper 8, the masterbatch is discharged into the required equipment.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
