Description

Technical Field

[0001] The present application relates to the technical field of plastic processing and transportation equipment, and in particular to a plastic shred feeding device. Background Art

[0002] For plastic crushing and granulation, the finished plastic generally needs to be crushed into strips first. Plastic strips often exist in the following three states: 1. Plastic strips are entangled during transportation to form a group of plastic strips; 2. The original plastic comes from a liquid container, and the surface of the plastic strips is attached to liquid; 3. The surface is statically charged due to friction during transportation.

[0003] The existing related technology uses a conveyor belt that is inclined toward the processing equipment at the ground level to pour the plastic shreds onto the surface of the running conveyor belt, so that the plastic shreds are lifted into the processing equipment under the action of the friction force of the conveyor belt.

[0004] With respect to the above-mentioned related technologies, the inventors believe that when the tangled plastic shreds are transported only by a conveyor belt, there is a probability that the shredded plastic shreds will roll down the conveyor belt to the ground, requiring workers to put them back onto the conveyor belt, which is inefficient. Utility Model Content

[0005] In order to improve the conveying efficiency of the existing conveyor belt for plastic shreds, the present application provides a plastic shred feeding device.

[0006] The following technical solutions are adopted:

[0007] A plastic shred feeding device comprises a conveyor belt, which is inclined toward a subsequent processing device from the side close to the ground, and side plates are respectively arranged on both sides of the conveyor belt, and the side plates are arranged along the length direction of the conveyor belt and extend upward on the side of the conveyor belt away from the ground. The conveyor belt is provided with a plurality of conveying forks arranged in an array at intervals along its length direction, and two adjacent conveying forks are parallel to each other and staggered on the projection surface of the conveyor belt surface.

[0008] By adopting the above technical solution, the plastic shreds will be entangled and form a ball during transportation. When transported only by the conveyor belt, the plastic shreds will roll to the ground along the conveyor belt under the action of gravity. By adding conveying forks, when the plastic shreds are poured onto the conveyor belt, the conveying forks can penetrate and fix the plastic shreds, so that the plastic shreds can be transported more stably. At the same time, the conveying forks are staggered to prevent the broken plastic from falling along the length of the conveyor belt.

[0009] Optionally, a material receiving hopper is respectively provided on the two side plates, and the material receiving hopper is inclined and connected to the conveying space of the conveyor belt.

[0010] By adopting the above technical solution, guidance is provided for the front-end equipment when dumping the plastic shreds onto the conveyor belt, thereby reducing the possibility of the plastic shreds floating out of the device when dumping.

[0011] Optionally, a baffle is further provided on the side of the conveyor belt close to the ground, two ends of the baffle are respectively connected to the two side panels, and a clearance groove for the conveying fork to pass through is opened on the baffle.

[0012] The above technical solution is used to prevent plastic shreds from falling off at the end of the conveyor belt.

[0013] Optionally, the conveying fork includes a base and a fork body, the fork body is rotatably connected to the base, and the fork body is provided with an elastic element that enables the fork body to return to an initial state after rotation.

[0014] By adopting the above technical solution, broken pieces of plastic will adhere to the conveying fork due to static electricity or surface humidity. After the fork body is rotated, the plastic adhered to the fork body will be ejected by the restoring force brought by the reset mechanism.

[0015] Optionally, the fork body includes a rotating shaft, the fork body is connected to the base via the rotating shaft, at least one limit block is arranged on the outer wall of the rotating shaft, a limit groove is opened in the base for the limit block to rotate along the axis of the rotating shaft, and the limit groove is arc-shaped.

[0016] By adopting the above technical solution, the rotation of the fork body is limited so that it rotates within the arc area limited by the limit groove, thereby avoiding excessive steering that affects the service life of the mechanism.

[0017] Optionally, the base is provided with countersunk bolts to connect it to the conveyor belt, and the areas of the fork body and the side of the base close to each other are equal.

[0018] By adopting the above technical solution, the transition between the fork body and the base is smooth, which prevents plastic scraps from entering the gap between the fork body and the base, making it easier to clean the conveying fork.

[0019] Optionally, both sides of the base perpendicular to the conveyor belt movement path are inclined.

[0020] By adopting the technical solution, it is convenient to clean the plastic fragments adhering to the surface of the base.

[0021] Optionally, the elastic element is a coil spring.

[0022] By adopting the above technical solution, the fork body can be reset after rotating.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. Provide a feeding device to prevent plastic shreds from rolling down along the length of the conveyor belt;

[0025] 2. The plastic fragments adhering to the surface of the fork can be bounced off by the rotatable and repositionable fork, making it easier to clean. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1 To Attachment Figure 4 This application is described in further detail.

[0032] Reference Figure 1 The embodiment of the present application discloses a plastic shred feeding device, including a conveyor belt 1, which is inclined toward a subsequent processing device from the side close to the ground, and side panels 11 are respectively provided on both sides of the conveyor belt 1, which are arranged along the length direction of the conveyor belt 1 and extend upward on the side of the conveyor belt 1 away from the ground. The conveyor belt 1 has a plurality of conveying forks 2 arranged in an array at intervals along its length direction, and the conveying forks 2 are perpendicular to the movement path of the conveyor belt 1, and two adjacent conveying forks 2 are parallel to each other and staggered on the projection surface of the conveyor belt 1 surface.

[0033] Reference Figure 1Specifically, the device also includes a support frame 12, which supports the conveyor belt 1 at an angle, and the side panels 11 are connected to the support frame 12. A hopper 14 is connected to the side panel 11, which is arranged obliquely. The hopper 14 extends away from the conveyor belt 1 at the side panel 11 and is connected to the conveying space of the conveyor belt 1. When the front-end equipment dumps the plastic shreds onto the conveyor belt 1, the hopper 14 can provide guidance to reduce the possibility of the plastic shreds floating out of the device when dumped. A baffle 13 is also provided on the side of the conveyor belt 1 close to the ground. The two ends of the baffle 13 are respectively connected to the two side panels 11 to surround the end of the conveyor belt 1. A clearance groove 131 for the conveying fork 2 to pass through is opened on the baffle 13, and the clearance groove 131 is rectangular. This prevents the plastic shreds from falling at the end of the conveyor belt 1.

[0034] Reference Figure 2 The transmission fork 2 includes a base 22 and a fork body 21. The fork body 21 includes three spines 211 arranged in a mountain shape. The spines 211 are of a quadrangular pyramid structure. The fork body 21 is rotatably connected to the base 22. The fork body 21 is provided with an elastic element 4 for restoring the fork body 21 to an initial state after rotation. The elastic element 4 is a coil spring. The fork body 21 includes a rotating shaft 3. The fork body 21 is connected to the base 22 through the rotating shaft 3. One end of the elastic element 4 is connected to the outer wall of the rotating shaft 3, and the other end is connected to the inner wall of the base 22. Two evenly spaced limit blocks 31 are provided on the outer wall of the rotating shaft 3 along its circumference. A limit groove 222 is provided in the base 22 for the limit block 31 to rotate along the axis of the rotating shaft 3. The limit groove 222 is arc-shaped.

[0035] Reference Figure 3 The base 22 is perpendicular to the moving path of the conveyor belt 1 and has inclined surfaces 223 on both sides thereof, which are arranged in a trapezoidal structure. Countersunk bolts 221 are arranged on the upper surface of the base 22, and the base 22 is connected to the conveyor belt 1 through the countersunk bolts 221. The edge of the bottom surface of the fork body 21 is flush with the edge of the surface of the base 22. This makes the transition between the fork body 21 and the base 22 smooth, prevents plastic scraps from entering the gap between the fork body 21 and the base 22, and facilitates the cleaning of the conveyor fork 2.

[0036] The implementation principle of a plastic shred feeding device in the embodiment of the present application is as follows:

[0037] During transportation, plastic shreds may become entangled and form a mass. When conveying only by conveyor belt 1, the mass of plastic shreds may roll to the ground along conveyor belt 1 under the action of gravity. By adding conveying forks 2, when the plastic shreds are poured onto conveyor belt 1, conveying forks 2 can penetrate and fix the mass of plastic shreds, so that the mass of plastic shreds can be transported more stably. At the same time, conveying forks 2 are staggered to prevent the fragmented plastic from falling along the length direction of conveyor belt 1.

[0038] In addition, broken plastics may adhere to the conveying fork 2 due to static electricity or surface humidity. After the fork body 21 is rotated, the plastics adhered to the fork body 21 are ejected by the restoring force brought by the reset mechanism, making it easier to clean the device after use.

[0039] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
