Description

Technical Field

[0001] This utility model relates to the field of color masterbatch metering and addition technology, specifically to a precise color masterbatch metering and addition device for multi-color wrapping film. Background Technology

[0002] Stretch film, also known as stretch film or heat shrink film, is a type of stretch film made from PE material. PE stretch film initially uses EVA as its self-adhesive material. To achieve the milky white color of PE stretch film, a milky white masterbatch is added to the PE material. The milky white processing device is a masterbatch machine that adds milky white masterbatch. The metering masterbatch mixer is suitable for the automatic proportional mixing of new materials, recycled materials, masterbatch, or additives. The metering masterbatch machine uses an imported DC brushless motor. It mixes according to a preset ratio and automatically converts the conditions set by the fully digital microcomputer control system into a speed that directly drives the precision screw to extrude the raw material.

[0003] Currently, the existing production process of stretch film requires the color masterbatch to be metered and added to the raw materials being stirred. However, in the production process of existing multi-color stretch film, the color masterbatch is manually metered and added to the raw materials all at once for mixing. This method of addition causes the color masterbatch to accumulate and requires a long mixing time to make the color masterbatch uniform, which has certain shortcomings. To address this, we propose a precise color masterbatch metering and adding device for multi-color stretch film. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a precise color masterbatch metering and adding device for multi-color stretch film, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a precision masterbatch metering and adding device for multi-color stretch film, comprising a masterbatch storage tank, a metering discharge cylinder for metering masterbatch is fixedly installed at the bottom of the masterbatch storage tank, a discharge mechanism is provided inside the masterbatch storage tank, and a drive mechanism for driving the discharge mechanism is provided at the top of the masterbatch storage tank.

[0006] Furthermore, the discharge mechanism includes a connecting rod that extends through the interior of the metering discharge cylinder.

A plug is provided on the outer side of the connecting rod, and the plug cooperates with the inner wall of the metering discharge cylinder.

[0007] Furthermore, the driving mechanism includes a slide rod and a servo motor. The slide rod is disposed inside the top of the color masterbatch storage tank via a sliding sleeve. The connecting rod is fixedly connected to one end of the slide rod, and a sliding frame is fixedly installed at the other end of the slide rod. A sliding groove is provided inside the sliding frame. The servo motor is fixedly installed on the top of the color masterbatch storage tank. A turntable is fixedly installed at the output end of the servo motor. A pivot pin is fixedly installed on one side of the turntable, and the pivot pin is slidably connected to the sliding groove.

[0008] Furthermore, an adjusting nut is threaded onto the outer side of the connecting rod, and the adjusting nut engages with the plug.

[0009] Furthermore, a limiting head is fixedly installed at the other end of the connecting rod.

[0010] Furthermore, the top of the plug is conical, and the interior of the plug has a hole that fits onto the outside of the connecting rod.

[0011] Furthermore, a mounting plate for mounting a servo motor is provided on one side of the top of the color masterbatch storage tank.

[0013] This utility model provides a precise color masterbatch metering and adding device for multi-color stretch film, which has the following features:

[0014] Beneficial effects:

[0015] 1. This multi-color stretch film uses a precise color masterbatch metering and adding device. Through the setup of a quantitative discharge cylinder, a discharge mechanism, and a drive mechanism, when adding color masterbatch to the raw materials, the servo motor drives the turntable and rotating pin to rotate. The rotating pin moves in an arc trajectory on the outside of the turntable, sliding within a chute while moving. This simultaneously drives the sliding frame and sliding rod to reciprocate up and down. When the sliding rod moves upward, it causes the connecting rod and valve plate to move upward, allowing the valve plate to move out from inside the quantitative discharge cylinder. The color masterbatch from the storage tank then falls into the quantitative discharge cylinder and is caught by the plug. Once the quantitative discharge cylinder is full of color masterbatch, the sliding rod drives the connecting rod downward, blocking the top of the quantitative discharge cylinder through the valve plate. Simultaneously, the plug moves out from the bottom of the quantitative discharge cylinder, opening the bottom and allowing the color masterbatch to be discharged into the raw materials. This achieves quantitative metering and addition of color masterbatch, and allows for intermittent addition, avoiding the need for excessive mixing time when adding large amounts of color masterbatch simultaneously, thus improving mixing efficiency.

[0016] 2. This multi-color stretch film uses a precision color masterbatch metering and adding device. By adjusting the setting of the nut, the position of the nut on the outside thread of the connecting rod can be adjusted, thereby limiting the position of the plug. By adjusting the position of the plug on the outside of the connecting rod and its position in the metering discharge cylinder when the connecting rod moves up and down, different discharge amounts can be adjusted. By adjusting the different discharge amounts, different metering and adding requirements can be met. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Please see Figures 1 to 7This utility model provides a technical solution: a precision masterbatch metering and adding device for multi-color stretch film, including a masterbatch storage tank 1, a metering discharge cylinder 2 for metering masterbatch discharge fixedly installed at the bottom of the masterbatch storage tank 1, a discharge mechanism inside the masterbatch storage tank 1, and a drive mechanism for driving the discharge mechanism at the top of the masterbatch storage tank 1; through the setting of the discharge mechanism and the drive mechanism, the masterbatch particles in the masterbatch storage tank 1 can be metered into the metering discharge cylinder 2 and then metered out, thereby realizing metered addition and intermittent addition, which facilitates the mixing of masterbatch with the raw materials for multi-color stretch film production and avoids the situation of adding too much masterbatch at one time and the mixing time being too long.

[0027] The discharge mechanism includes a connecting rod 4, which is installed inside the quantitative discharge cylinder 2. A valve plate 5 is fixedly installed on the outside of the connecting rod 4, and the valve plate 5 cooperates with the quantitative discharge cylinder 2. A plug 6 is provided on the outside of the connecting rod 4, and the plug 6 cooperates with the inner wall of the quantitative discharge cylinder 2. Through the connection rod 4, valve plate 5 and plug 6 being installed inside the quantitative discharge cylinder 2, when the connecting rod 4 moves upward, the valve plate 5 moves out from the top of the quantitative discharge cylinder 2, opening the top of the quantitative discharge cylinder 2 so that the color masterbatch can enter the quantitative discharge cylinder 2. When the connecting rod 4 moves downward, the valve plate 5 covers the top of the quantitative discharge cylinder 2, and the plug 6 moves out from the bottom of the quantitative discharge cylinder 2, opening the bottom of the quantitative discharge cylinder 2 so that the color masterbatch in the quantitative discharge cylinder 2 can be discharged from the bottom and added into the multi-color stretch film mixing equipment.

[0028] The driving mechanism includes a slide rod 3 and a servo motor 9. The slide rod 3 is mounted inside the top of the masterbatch storage tank 1 via a sliding sleeve. The connecting rod 4 is fixedly connected to one end of the slide rod 3, and a sliding frame 7 is fixedly installed at the other end of the slide rod 3. A sliding groove 8 is opened inside the sliding frame 7. The servo motor 9 is fixedly installed on the top of the masterbatch storage tank 1. A turntable 10 is fixedly installed at the output end of the servo motor 9. A pivot pin 11 is fixedly installed on one side of the turntable 10. The pivot pin 11 is slidably connected to the sliding groove 8. The servo motor 9 can drive the turntable 10 and the pivot pin 11 to rotate. When the pivot pin 11 rotates, it moves in an arc trajectory outside the turntable 10. The pivot pin 11 can slide in the sliding groove 8 while moving, and at the same time drive the sliding frame 7 and the slide rod 3 to move up and down. The slide rod 3 drives the connecting rod 4 to move up and down.

[0029] An adjusting nut 13 is installed on the outer thread of the connecting rod 4, and the adjusting nut 13 cooperates with the plug 6. By adjusting the position of the adjusting nut 13 on the outer thread of the connecting rod 4, the plug 6 can be limited. By adjusting the position of the plug 6 on the outer side of the connecting rod 4 and its position in the metering discharge cylinder 2 when the connecting rod 4 moves up and down, different discharge volumes can be adjusted. By adjusting the different discharge volumes, different metering and addition requirements can be met.

[0030] A limiting head 12 is fixedly installed at the other end of the connecting rod 4; the limiting head 12 can limit the movement of the adjusting nut 13 and the plug 6.

[0031] The top of the plug 6 is conical, and the inside of the plug 6 has a hole that fits on the outside of the connecting rod 4. The conical shape of the top of the plug 6 facilitates the movement of the plug 6 from the bottom of the metering discharge cylinder 2 into the metering discharge cylinder 2 when the connecting rod 4 moves upward, thus improving the accuracy of its upward movement into the metering discharge cylinder 2.

[0032] A mounting plate for mounting the servo motor 9 is provided on one side of the top of the color masterbatch storage tank 1; the installation of the mounting plate improves the stability of the servo motor 9 installation.

[0033] The top of the masterbatch storage tank 1 is equipped with a feeding port, and the top of the feeding port is equipped with a feeding cover; by opening the feeding cover, masterbatch can be added into the masterbatch storage tank 1 through the feeding port.

[0034] In summary, this multi-color stretch film precision masterbatch metering and adding device, when in use, first adjust the metering amount according to the quantitative requirements of the masterbatch. This adjustment is achieved by rotating the adjusting nut 13, causing it to move threadedly outside the connecting rod 4. This movement of the adjusting nut 13 limits the height of the plug 6. By adjusting the position of the plug 6 outside the connecting rod 4 and its position within the metering discharge cylinder 2 as the connecting rod 4 moves up and down, different discharge amounts can be adjusted. Different discharge amounts can meet different metering and adding requirements. After adjustment, the servo motor 9 is activated to meter and add the masterbatch into the stretch film production mixing equipment. The servo motor 9 drives the turntable after activation. When the turntable 10 and the pivot pin 11 rotate, the pivot pin 11 moves in an arc trajectory outside the turntable 10. It can slide in the slide groove 8 while rotating, and at the same time drive the slide frame 7 and the slide rod 3 to move up and down. The slide rod 3 drives the connecting rod 4 to move up and down. When the connecting rod 4 moves up, the valve plate 5 moves out from the top of the metering discharge cylinder 2, opening the top of the metering discharge cylinder 2, so that the color masterbatch can enter the metering discharge cylinder 2. When the connecting rod 4 moves down, the valve plate 5 can cover the top of the metering discharge cylinder 2, and the plug 6 moves out from the bottom of the metering discharge cylinder 2, opening the bottom of the metering discharge cylinder 2, so that the color masterbatch in the metering discharge cylinder 2 can be discharged from the bottom and added into the multi-color wrapping film mixing equipment.
