DETAILED DESCRIPTION

[0024] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] refer to Figure 1-6 A feeding device of an injection molding machine comprises a base 1. Positioning blocks 101 for positioning a material strip are arranged on both sides of the top of the base 1. The two positioning blocks 101 are symmetrically arranged with a feeding port as the center. The symmetrically arranged positioning blocks 101 can ensure the accurate positioning of the material strip, thereby improving the product quality. The staff quickly and the positioning blocks 101 on both sides are slidably connected to the top surface of the base 1. A first adjusting groove 102 is arranged on the top of the base 1 and one side of the positioning block 101. A fixing component for fixing the positioning block 101 is arranged in the first adjusting groove 102.

[0026] The positioning block 101, the first adjustment slot 102 and the fixing assembly can effectively ensure the accurate positioning of the material strip, improve production efficiency and product quality, reduce the scrap rate caused by position deviation, and increase production stability and continuity. At the same time, the fixing assembly can make the positioning block 101 adapt to different types of material strips and different product requirements, thereby improving production flexibility.

[0027] Specifically, the fixing assembly includes a stud bolt 2 and a nut 201. A fixing plate 202 is provided on one side of the positioning block 101 close to the first adjustment slot 102. A fixing hole 203 is provided on the fixing plate 202, and the fixing hole 203 is arranged at the top of the first adjustment slot 102. The stud bolt 2 is arranged in the fixing hole 203, and the stud bolt 2 does not contact the fixing hole 203. One end of the stud bolt 2 extends to the bottom of the base 1, and one end of the stud bolt 2 extends to the bottom of the base 1 through the first adjustment slot 102. The nut 201 is arranged The bottom of the stud bolt 2 is threadedly connected to the stud bolt 2, and the nut 201 is in contact with the bottom of the base 1. When the staff adjusts the distance between the two positioning blocks 101 and needs to fix them, first, fix one end of the stud bolt 2 and use a wrench to tighten the nut 201 at the other end to fix the positioning block 101 on the base 1. A gasket can be set on the side of the nut 201 close to the bottom of the base 1. The gasket can increase the contact area between the nut 201 and the bottom of the base 1, thereby improving the fixing effect.

[0028] In order to facilitate the staff to move the positioning block 101 to adapt to different types of material belts, a plurality of slide rails 104 are provided on the top of the base 1, and a plurality of first slide grooves 103 are provided at the bottom of each positioning block 101. The slide rails 104 are slidably connected to the inner wall of the first slide groove 103. When the staff moves the positioning block 101, the slide rails 104 will be slidably connected to the inner wall of the first slide groove 103. Through the provided slide rails 104 and first slide grooves 103, it can be ensured that when the staff moves the positioning block 101, the side of the positioning block 101 is on the same horizontal plane, avoiding the positioning block 101 from being offset or tilted. The first slide groove 103 has a dovetail-shaped structure, and the dovetail groove has high precision and can achieve zero-gap alignment and tight fit. A placement groove 105 for placing the material belt is provided on the opposite side of the two positioning blocks 101. The placement groove 105 provides an installation position for the material belt, which is convenient for the staff to place the material belt.

[0029] When the feeding device feeds the material belt into the injection molding machine, in order to prevent the material belt from shaking during the injection molding process, the material belt is usually fixed to improve product quality.

[0030] The present embodiment also includes a limiting mechanism for limiting the movement of the material belt, the limiting mechanism includes a cylinder 3, a base plate 301, and two moving blocks 302. Support blocks 303 are provided on both sides of the bottom of the base 1, and a mounting seat 304 is provided at the bottom of the support block 303. The cylinder 3 is arranged on the mounting seat 304, and the base plate 301 is arranged on the telescopic rod of the cylinder 3. The two moving blocks 302 are respectively arranged on both sides of the top of the base plate 301, and the two moving blocks 302 are circumferentially arranged with the feeding port as the center. The top of each moving block 302 is connected with a limiting block 305 for limiting the material belt. When the feeding device feeds the material belt into the injection molding machine, the cylinder 3 can be started, and the cylinder 3 will drive the base plate 301 to shrink, so that the limiting block 305 is driven by the moving block 302 to limit the material belt in the placement groove 105, so as to avoid the material belt from shaking or deflecting during the injection molding process, thereby improving the quality of the final product. When the cylinder 3 is extended, the limiting of the material belt can be released.

[0031] Specifically, second sliding grooves 306 are provided on both sides of the top of the base 1. A sliding block 307 is fixedly connected to the side of the positioning block 101 away from the placement groove 105. Both the limiting block 305 and the sliding block 307 are slidably connected to the inner wall of the second sliding groove 306. A sliding column 308 is provided on the side of the sliding block 307 close to the limiting block 305. A sliding groove 309 is provided on the limiting block 305. The sliding column 308 is slidably connected to the inner wall of the sliding groove 309. The sliding groove 309 is in the shape of a reverse slash. The limiting block 305 is rotatably connected to the moving block 302. When the air cylinder 3 extends, it will drive the bottom plate 301 to move upward, thereby driving the limiting block 305 away from the placement groove 105 through the moving block 302. Since the sliding column 308 is fixed and the sliding groove 309 on the limiting block 305 is in the shape of a reverse slash, when the limiting block 305 moves upward, the limiting block 305 will first move upward a certain distance to脱离 the placement groove 105, and then rotate around the moving block 302. At this time, the limiting blocks 305 on both sides are in an outward open state, providing a larger space for the staff to place the tape.

[0032] In this embodiment, in order to enable the limiting mechanism to limit tapes of different models, a second adjustment groove 4 is provided on the top of the bottom plate 301. A first screw rod 401 is rotatably connected in the second adjustment groove 4. The first screw rod 401 is provided with two threaded sections, and the two threaded sections have opposite thread directions. The two moving blocks 302 are respectively threadedly connected to the two threaded sections and are symmetrically arranged with the feeding port as the center. Both moving blocks 302 are slidably connected to the inner wall of the second adjustment groove 4. The moving block 302 contacts the inner wall of the second adjustment groove 4 to prevent the moving block 302 from rotating when the first screw rod 401 is rotated, ensuring that the moving block 302 can move in the second adjustment groove 4. One side of the first screw rod 401 penetrates the side of the bottom plate 301 and extends to the outside of the bottom plate 301. A rotating block is provided on the side of the first screw rod 401 away from the bottom plate 301. The rotating block can help the staff obtain a larger torque and facilitate the staff to rotate the first screw rod 401;

[0033] When the staff needs to limit tapes of different models, first loosen the nut 201 of the fixing component so that the positioning block 101 can move. Then rotate the first screw rod 401. The first screw rod 401 will drive the two moving blocks 302 to move in opposite directions. The moving blocks 302 will move together with the limiting blocks 305. Since the sliding block 307 is fixedly connected to the positioning block 101, the limiting block 305 will drive the sliding block 307 to move in the second sliding groove 306 through the sliding column 308. At the same time, due to the self-locking property of the threaded connection, it is not necessary to fix the positioning block 101 with the fixing component. If it is necessary to improve the movement stability of the limiting mechanism, the positioning block 101 can be fixed with the fixing component.

[0034] In this embodiment, in order to facilitate the staff to limit the material strips of different thicknesses, a accommodating groove 5 is provided on the side of the limiting block 305 close to the placement groove 105, and an adjusting plate 501 is provided in the accommodating groove 5. The bottom of the adjusting plate 501 is fixedly connected to the limiting column 502. One side of the limiting column 502 passes through the limiting block 305 and extends to the outside of the limiting block 305. The bottom of the limiting column 502 is fixedly connected to the limiting plate 505. The limiting plate 505 has a rectangular structure. The limiting plate 505 with a rectangular structure can be increased with The contact area of ​​the material strip is increased, thereby improving the limiting effect, and the limiting plate 505 is in contact with the placement groove 105, and a second screw 503 is rotatably connected in the accommodating groove 5, and the limiting plate 505 is threadedly connected to the second screw 503. One side of the second screw 503 passes through the side of the limiting block 305 and extends to the outside of the limiting block 305. A guide rod 504 is provided in the accommodating groove 5, and the guide rod 504 passes through the adjusting plate 501 and is slidably connected to the adjusting plate 501. The guide rod 504 can limit the radial freedom of the adjusting plate 501.

[0035] When the staff needs to adjust the material strips of different thicknesses, they only need to rotate the second screw 503, and the second screw 503 will move along the guide rod 504, thereby driving the limit plate 505 to move through the limit column 502, thereby achieving the purpose of adjustment. When it comes to material strips of different thicknesses, there is no need to debug the cylinder 3, and they only need to rotate the second screw 503 to limit the material strips of different thicknesses, which is convenient to operate.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
