Description

Technical Field

[0001] The utility model relates to the technical field of plastic film production, in particular to a plastic film raw material feeding device. Background Art

[0002] In the production process of plastic films, as one of the key devices, the performance of the raw material feeding device directly affects the production efficiency and product quality. Traditional plastic film raw material feeding devices often have problems such as inaccurate control of the discharge amount, difficult equipment maintenance, and short service life. These problems not only increase the production cost but also affect the market competitiveness of products.

[0003] First of all, inaccurate control of the discharge amount is a major drawback of traditional feeding devices. Due to the lack of precise material control mechanisms and stable locking devices, the discharge amount during the feeding process is often difficult to maintain stable, resulting in waste during the production process and unstable product quality. This not only increases the production cost but also reduces the production efficiency.

[0004] Secondly, difficult equipment maintenance is also a major challenge faced by traditional feeding devices. Due to the unreasonable internal structure design of the feeding hopper, cleaning and maintenance work often requires a large amount of manpower and time. This not only increases the maintenance cost but also affects the normal operation and service life of the equipment; Finally, short service life is another significant problem of traditional feeding devices. Due to the lack of effective reset mechanisms and anti-friction designs, the feeding device is often easily affected by mechanical wear during operation, resulting in a decline in equipment performance and a shortening of the service life. This not only increases the replacement cost of the enterprise but also affects the overall stability and reliability of the production line. Therefore, we provide a plastic film raw material feeding device. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] In order to more clearly and completely illustrate the technical solution of the utility model, the utility model will be further described below with reference to the accompanying drawings.

[0025] Embodiment

[0026] As Figures 1-5 shown, a raw material feeding device for a plastic film production line proposed by an embodiment of the utility model mainly includes a feeding hopper 1 and a discharge pipe 2; the feeding hopper 1 is used for storing and initially distributing plastic film raw materials, and the discharge pipe 2 is fixedly installed at the lower port of the feeding hopper 1 and is responsible for guiding the raw materials to downstream processing equipment.

[0027] Among them, on the side wall of the discharge pipe 2, a slot 3 is horizontally opened. The size of the slot opening is designed to be large enough to allow the material control baffle 4 to slide freely in the slot without obstruction. The material of the material control baffle 4 is selected to be wear-resistant and have a certain rigidity to ensure that it can maintain stable sliding performance under frequent operations.

[0028] On the lower end surface of the material control baffle 4, a limit jack 5 is opened. Correspondingly, a rectangular groove 6 is opened on the side of the discharge pipe 2. The depth and width of the rectangular groove 6 are carefully designed according to the size of the limit jack 5 and subsequent components to ensure precise cooperation of all components. On the inner side wall of the rectangular groove 6, a placement groove 7 is opened for installing the core components of the limit mechanism. The fixed rod 8 is horizontally installed in the placement groove 7, and both ends are fixed on the end walls of the placement groove 7 to ensure its stability. The first spring 9 is sleeved around the fixed rod 8 to provide an elastic reset force for the limit mechanism. There are two sliding sleeve blocks 10, which are respectively slidably sleeved on the fixed rod 8 and are pushed by both ends of the first spring 9 to maintain a certain initial distance. The two sliding sleeve blocks 10 are fixedly connected by a lap joint plate 11. The width of the lap joint plate 11 is slightly smaller than the width of the rectangular groove 6 to ensure that it can slide smoothly in the rectangular groove 6. A limit insertion rod 12 is fixedly connected to the upper end surface of the lap joint plate 11. The shape and size of the insertion rod match the limit jack 5 at the lower end of the material control baffle 4. When it is necessary to fix the position of the material control baffle 4, the lap joint plate 11 and the limit insertion rod 12 are moved upward by operations such as manual or mechanical driving until the limit insertion rod 12 is completely inserted into the limit jack 5 to achieve the locking of the material control baffle 4.

[0029] Furthermore, on the side of the material control baffle 4, an L-shaped connecting frame 13 is fixedly connected. The design of the connecting frame enables the long arm part to extend to the outside of the discharge pipe 2, facilitating connection with the second sliding sleeve block 17, while the short arm part closely adheres to the side of the material control baffle 4 to increase the connection stability. On the front and back sides of the discharge pipe 2, that is, on the left and right sides, strip-shaped grooves 14 are horizontally opened. The length and depth of the grooves are designed according to the size of the second sliding sleeve block 17 and the second spring 16 to ensure that they can slide smoothly therein. The transverse fixing rod 15 is fixedly connected between the two end walls of the strip-shaped groove 14 to provide a sliding track for the second sliding sleeve block 17. The second spring 16 is sleeved around the transverse fixing rod 15, and both ends are respectively fixedly connected to the end wall of the strip-shaped groove 14 and one end surface of the second sliding sleeve block 17. When the material control baffle 4 is moved, the second spring 16 will be compressed or stretched, thereby generating a reset force to help the material control baffle 4 return to the initial position. The second sliding sleeve block 17 transmits the reset force of the second spring 16 to the material control baffle 4 through its surface fixedly connected to the L-shaped connecting frame 13.

[0030] One end of the second spring 16 is fixedly connected to the end wall of the strip-shaped groove 14, and the other end is fixedly connected to one end surface of the second sliding sleeve block 17. This fixing method ensures that the second spring 16 can generate corresponding elastic deformation when the material control baffle 4 moves, providing a stable reset force for the material control baffle 4.

[0031] Furthermore, a pulling handle 18 is fixedly installed on one end surface of the material control baffle 4. The design of this handle facilitates the operator to hold, so as to easily move the material control baffle 4; an inspection door 19 is installed at the periphery of the feeding hopper 1. The setting of the inspection door facilitates the cleaning, maintenance and inspection of the inside of the feeding hopper 1, ensuring the long-term stable operation of the feeding device.
