Technical Field

[0001] This utility model relates to the technical field of thin film raw material injection devices, specifically a thin film raw material injection mechanism. Background Technology

[0002] In the film production process, after the raw materials are purchased, they are transported to the factory area in ton bags, and then transported to the top of the production tank for addition via elevators, flatcars and tracks.

[0003] However, during the current raw material addition process, after the ton bags are in place, workers need to crawl under the flatbed truck to untie the ropes. The entire operation is done by workers, which is inefficient and poses a certain degree of danger. At the same time, the addition of raw materials into the ton bags relies entirely on their own weight. During the operation, there is a possibility of blockage at the opening of the ton bag. When clearing the blockage, it is necessary to crawl under the flatbed truck to clear it.

[0004] In view of this, we propose a thin film raw material feeding mechanism. Utility Model Content

[0018] 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.

[0019] Please see Figures 1-6 A film raw material feeding mechanism includes a track 1 and a baffle 2 that encloses the track 1. A flatcar 3 is provided on the track 1. The movement of the flatcar 3 on the track 1 can transport the ton bag containing the film raw material, making the transportation and feeding of the raw material more convenient. The baffle 2 can prevent the inside of the track 1 from being hollow, preventing the raw material from being difficult to clean when it is spilled, and at the same time facilitating manual movement between the tracks 1.

[0020] In this embodiment, a feeding position 4 is provided on the baffle 2, and a feeding trough 5 is provided in the feeding position 4. The feeding trough 5 can be used to add raw materials. The feeding position 4 enables the flat car 3 to be accurately positioned when feeding. In addition, a filter screen 6 is fixedly installed inside the feeding trough 5. The filter screen 6 is used to disperse and screen the raw materials, prevent the entry of clumped raw materials and speed up the feeding speed.

[0021] Please see Figures 2-4 The feeding position 4 is equipped with a rope cutting mechanism 7, which is used to cut the fixed rope at the bottom of the ton bag conveyed by the flat car 3, so as to facilitate the next step of opening the ton bag for feeding. The automatic rope cutting does not require manual operation, which can enhance safety and improve work efficiency. In this embodiment, the rope cutting mechanism 7 includes a slide bar 71, which is fixedly installed inside the feeding position 4 and is positioned in the forward direction of the track 1. The slide bar 71 includes a rod body 711, which is a round rod with its bottom end fixedly connected to the bottom surface of the inner bottom of the feeding position 4. This ensures that the rod body 711 is fixedly installed inside the feeding position 4 without any offset. Simultaneously, the height of the top of the rod body 711 is less than the height of the inner bottom of the flatcar 3, so the rod body 711 does not affect the movement of the flatcar 3. A piston head 712 is fixedly installed at the top of the rod body 711. A slide block 72 is fitted onto the surface of the piston head 712, with the bottom of the slide block 72 communicating with the outside and the top being a closed structure, forming a sealed space between the top of the piston head 712 and the interior of the slide block 72. An air inlet 713 is provided at the upper and lower ends of the through rod 711 and the piston head 712. The air inlet 713 is connected to an air pump through a pipe. The air pump can fill and release air in the space between the top of the piston head 712 and the inside of the slide 72, thereby adjusting the positive and negative pressure of the sealed space between the top of the piston head 712 and the inside of the slide 72, and thus controlling the displacement of the slide 72 along the rod 711.

[0022] Please see Figure 4 A crossbar 73 is fixedly installed at the top of the slide block 72, forming a triangular structure between the slide block 72 and the crossbar 73 to strengthen the connection and enhance the bending and compressive strength of the crossbar 73. A rope threading rod 74 is fixedly installed at the end of the crossbar 73 away from the slide block 72. The rope threading rod 74 is perpendicular to the crossbar 73. The rope threading rod 74 is cylindrical with a hemispherical bottom. When the rope threading rod 74 comes into contact with the ton bag, it will not damage the ton bag. The rope threading rod 74 and the crossbar 73 form a horizontal "7" shape. The rope threading rod 74 can be inserted between the ton bag and the fixing rope by the displacement of the crossbar 73.

[0023] In this embodiment, the through crossbar 73 has a rotating groove 75, and a rotating seat 76 is fixedly installed in the rotating groove 75. A rotating cutter 77 is rotatably installed on the rotating seat 76. The rotating cutter 77 can rotate around the rotating seat 76. The rotating groove 75 is a through groove, and the angle of the rotating cutter 77 is not limited. When not in use, the rotating cutter 77 can be stored in the rotating groove 75, which improves safety.

[0024] Specifically, a limiting rod 78 is fixedly installed within the feeding position 4. The limiting rod 78 contacts the rotating cutter 77, and the contact surface between the limiting rod 78 and the rotating cutter 77 is provided with an inclined surface. When the rotating cutter 77 descends, it contacts the inclined surface of the limiting rod 78, and the inclined surface presses against one end of the rotating cutter 77, causing the rotating cutter 77 to rotate around the rotating seat 76, thereby exposing the rotating groove 75 for operation and realizing the cutting of the fixed rope. Moreover, the cutting force gradually increases, and the cutting direction changes along the circumference of the rotating seat 76, thereby improving the stability during cutting and ensuring the cutting effect within a small displacement range.

[0025] Please see Figures 5-6 The feeding trough 5 is equipped with an arch-breaking mechanism 8, which is used to disperse and transport the sample in the ton bag, enhance the conveying effect, and break the arch of the raw material to avoid problems such as bridging and blockage at the discharge end.

[0026] Please see Figure 5 The anti-arching mechanism 8 includes multiple mounting rods 81 located within the feeding trough 5. The tops of the mounting rods 81 are rounded to prevent raw materials from remaining on them during addition, thus avoiding material buildup. The mounting rods 81 are arranged in an array, which enhances the stability of the workpieces connected to them. A limiting ring 82 is fixedly installed between the mounting rods 81, and an anti-arching cone 83 is slidably mounted within the limiting ring 82. The anti-arching cone 83 has two conical side sections, and its overall shape is cross-shaped, resulting in excellent anti-arching performance at its tip. Simultaneously, the internal conical structure prevents raw materials from remaining on the anti-arching cone 83. The top of the anti-arching cone 83 is spherical, preventing damage to the ton bag and the introduction of impurities.

[0027] In this embodiment, a connecting rod 86 is fixedly installed at the bottom end of the mounting rod 81, and a sliding rod 85 is fixedly connected to the bottom end of the connecting rod 86. The connecting rod 86 has a cylindrical structure, and the contact part between the connecting rod 86 and the sliding rod 85 has a frustum structure, so that the raw material will not remain on the connecting rod 86 and the sliding rod 85.

[0028] Furthermore, the slide rod 85 includes a rod body 851, with a piston head 852 fixedly mounted at the top of the rod body 851. A sliding seat 84 is sleeved on the surfaces of the piston head 852 and the rod body 851. The top of the sliding seat 84 is fixedly connected to the arch-breaking cone 83, and the top of the sliding seat 84 is open to the outside. This creates a closed space between the piston head 852, the rod body 851, and the sliding seat 84. An air inlet 853 is provided through the surface and bottom of the piston head 852. The air inlet 853 is fixedly connected to an air pump via a pipe. The air pump can control the air pressure within the closed space between the piston head 852, the rod body 851, and the sliding seat 84, thereby controlling the relative position of the sliding seat 84. It should be noted that the piston head 852 and the sliding seat 84 are elastically connected by a spring. After the spring is compressed, the sliding seat 84 can move upward rapidly through the combination of rapid compression and the spring's rebound force. This enables the arch-breaking cone 83 to move upward rapidly, thereby achieving efficient arch breaking and dispersion of raw materials.

[0029] Please see Figure 7 A cleaning mechanism 9 is provided between the feeding trough 5 and the limiting ring 82 to clean the cut rope and other debris left on the surface of the filter screen 6, and at the same time, the raw materials left on the surface of the filter screen 6 can be re-injected.

[0030] The cleaning mechanism includes a cleaning ring 92, which is rotatably mounted on a limiting ring 82, allowing the cleaning ring 92 to rotate along the limiting ring 82. It should be noted that the contact surface between the cleaning ring 92 and the limiting ring 82 has an "H" shaped structure (not shown in the figure), so that the cleaning ring 92 will not detach from the limiting ring 82.

[0031] Multiple cleaning rods 93 are fixedly installed on the surface of the cleaning ring 92. The multiple cleaning rods 93 are arranged in a circular array. The bottom end of the cleaning rod 93 is a brush structure, and the cleaning rod 93 contacts the surface of the filter screen 6, thereby cleaning the surface of the filter screen 6. At the same time, the cleaning rod 93 is set at an angle from the center to the edge of the feeding groove 5, so that the debris on the filter screen 6 can be displaced along the angle towards the edge of the feeding groove, which is convenient for subsequent discharge.

[0032] The surface of the feeding trough 5 is detachably connected to a gate 91. The detachable connection method includes snap-fit ​​connection, bolt connection or hinge connection, which allows the gate 91 to be opened and closed during feeding and opened during cleaning to facilitate the discharge of debris.

[0033] Multiple drive plates 94 are fixedly installed at the bottom of the cleaning ring 92. An air pump is connected to the limiting ring 82 through a pipe. The multiple drive plates 94 are arranged in a circular array and the drive plates 94 are provided with bevels. This allows the airflow driven by the air pump to impact the drive plates 94, thereby causing the drive plates 94 to move and thus causing the cleaning ring 92 to rotate along the limiting ring 82.

[0034] It should be noted that at least one air pump is provided, and the air pump is controlled by valves and pipes to drive one or more of the slide 72, slide 84 or cleaning ring 92 to work.

[0035] A thin film raw material injection mechanism, the working principle of which is as follows: Sample loading: Positive pressure is injected into the slide block 72 through the air pump and pipeline, causing the slide block 72 to move upward along the slide rod 71. The upward movement of the slide block 72 drives the crossbar 73 and the rope rod 74 to move upward. The flat car 3 moves the ton bag along the track 1 until the flat car 3 stops at the feeding position 4. When the flat car 3 moves, the lower end of the ton bag will contact the rope rod 74, and the rope rod 74 will squeeze the ton bag and get it stuck between the ton bag and the fixing rope.

[0036] Rope cutting: Pressure is drawn into the slide block 72 through the air pump and pipeline. When negative pressure is drawn, the slide block 72 moves down along the slide rod 71. When the slide block 72 moves down, it drives the crossbar 73 and the rope threading rod 74 to move down, so that the fixed rope comes into contact with the bottom end of the crossbar 73. When the crossbar 73 moves down, it drives the rotating cutter 77 to come into contact with the limiting rod 78. The limiting rod 78 comes into contact with the rotating cutter 77, so that the rotating cutter 77 rotates along the rotating seat 76, which in turn brings the rotating cutter 77 into contact with the fixed rope, thereby cutting the fixed rope. After cutting, the raw materials in the ton bag move down.

[0037] Arch breaking: During normal operation, negative pressure is injected into the sliding seat 84 through the air pump and pipeline, causing the sliding seat 84 to move downward along the sliding rod 85. As the sliding rod 85 moves downward, it pulls the spring, and the arch breaking cone 83 can disperse the raw materials to the left and right, accelerating the feeding rate. When the bag opening is blocked, positive pressure is quickly injected into the sliding seat 84, and the restoring force of the spring causes the sliding seat 84 to move upward quickly along the sliding rod 85, thereby driving the arch breaking cone 83 upward to clear the blockage at the ton bag outlet. Then, by pumping pressure, the sliding seat 84 is moved downward to reset.

[0038] Cleaning: After feeding is completed, the gate 91 is opened, and the air pump operates to impact the drive plate 94 with airflow, thereby driving the drive plate 94 to move. The displacement of the drive plate 94 drives the cleaning ring 92 to rotate. The rotation of the cleaning ring 92 drives the cleaning rod 93 to clean the surface of the filter screen 6. Smaller raw materials are fed through the filter screen 6, while larger debris and cut ends of the ton bag rope are moved by the cleaning rod 93 and finally discharged through the gate 91, thus achieving the cleaning effect.
