Description

Technical Field

[0001] The utility model relates to the technical field of plastic product production, and more specifically, to a feeding device for plastic product production. Background Art

[0002] Plastic is a high molecular compound polymerized from monomers through addition polymerization or condensation polymerization. It has a medium deformation resistance, between that of fiber and rubber, and is composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. In the production process of plastic products, a large number of bagged plastic particles are required as raw materials. When existing equipment loads such bagged plastic particles, a robot arm will be used to pierce into the raw material bag, and then the raw material bag will be grabbed to the funnel, and the raw material bag will be passed through the cutting knife on the funnel to cut the bag, so that the plastic particles therein flow into the funnel, completing the loading operation. However, after the robot arm that has pierced into the bag stops grabbing the bag, due to the relatively light weight of the bag, some plastic bags cannot automatically fall off from the robot arm, which will interfere with the robot arm grabbing the next raw material bag, thereby affecting the loading operation of the plastic particles.

DETAILED DESCRIPTION

[0022] The following description is only a preferred embodiment of the present invention and does not limit the protection scope of the present invention.

[0023] Implementation 1

[0024] A feeding device for producing plastic products, such as Figure 1-Figure 4 As shown, it includes a mechanical arm 1 and a support frame 2; the movable end of the mechanical arm 1 is bolted to the support frame 2; it also includes a cutter 3, a steel needle 4, a telescopic driving member 5, a push plate 6, a collecting component and a driving component; a collecting component is arranged on the side of the mechanical arm 1; the collecting component is used to collect raw materials; the collecting component is connected to the cutter 3, the cutter 3 is set to an alloy material, and the packaging bag is cut by the cutter 3; twelve steel needles 4 are rotatably connected to the support frame 2 through a torsion spring shaft; two telescopic driving members 5 are bolted to the middle part of the support frame 2; the telescopic ends of all the telescopic driving members 5 are commonly fixed to a push plate 6; the support frame 2 is connected to a driving component; the driving component is used to drive the steel needles 4 to rotate.

[0025] The collecting assembly includes a funnel 201 and a receiving plate 202; the funnel 201 is arranged on the side of the robotic arm 1; the receiving plate 202 is bolted to the upper inner side of the funnel 201, and the receiving plate 202 is set to an alloy material; a plurality of through holes are opened on the receiving plate 202, and the through holes can be set to circular holes or long strip holes; the receiving plate 202 is bolted to the cutter 3.

[0026] The driving assembly includes a telescopic driving member 203 and a round rod 204; four telescopic driving members 203 are bolted to the support frame 2; two round rods 204 are arranged on the inner side of the support frame 2, and the round rods 204 are fixedly connected to the telescopic ends of the telescopic driving members 203 of corresponding height; a slide groove 91 is opened at the upper end of each steel needle 4; each round rod 204 slides in the corresponding slide groove 91, and the steel needle 4 inserted into the raw material package is rotated toward the middle of the support frame 2 by the round rod 204, so as to grab and fix the raw material package.

[0027] During the loading operation, the robot arm 1 drives the support frame 2 and the parts thereon to move, so that the lower end of the steel needle 4 is vertically inserted into the raw material bag, and then the telescopic driving member 203 pushes the round rod 1 204 to move, and the round rod 1 204 drives the steel needle 4 to move, so that the steel needle 4 rotates around the torque shaft thereon, and the lower end of the steel needle 4 rotates toward the middle of the support frame 2, so that the raw material bag is grabbed by all the steel needles 4, and then the robot arm 1 drives the support frame 2 and the parts thereon to move, so that the steel needle 4 drives the raw material bag to pass over the cutter 3, so that the lower part of the packaging bag is cut open by the cutter 3, and the plastic particles in the packaging bag fall onto the receiving plate 202, and then fall from the through hole on the receiving plate 202 to In the funnel 201, the raw material loading operation is completed, and then the robot arm 1 drives the support frame 2 and the parts thereon to move, so that the steel needle 4 drives the plastic bag to move to the waste collection area, and then the telescopic driving member 203 pulls the round rod 204 to move, so that the round rod 204 pushes the steel needle 4 back to a vertical state, thereby causing the plastic bag to fall into the waste collection area; since the plastic bag is relatively light in weight, some of the plastic bags pierced on the steel needle 4 cannot fall automatically, therefore, the telescopic driving member 5 drives the push plate 6 to move downward, so that the push plate 6 pushes the middle part of the plastic bag to move downward, thereby pushing the plastic bag off the steel needle 4, avoiding interference with the plastic particle loading operation due to the plastic bag hanging on it and being unable to fall off.

[0028] Implementation 2

[0029] Based on Implementation Plan 1, Figure 1-Figure 5 As shown, it also includes a pushing component; the supporting frame 2 is connected to the pushing component; the pushing component includes a push plate 205 and a linkage unit; six push plates 205 are arranged on the lower side of the supporting frame 2, the push plates 205 are located on the outside of the corresponding steel needles 4, and the push plates 205 are in contact with the corresponding push plates 1 6; the supporting frame 2 is connected to the linkage unit; the linkage unit is used to drive the push plates 205 to move vertically, and the plastic bags are pushed downward by the push plates 205 to prevent the plastic bags from hanging on the steel needles 4.

[0030] The linkage unit includes a round rod 206 and a spring 207; each push plate 205 is bolted with two round rods 206, the round rods 206 are slidably connected to the support frame 2, and the round rods 206 are set to an alloy material; each round rod 206 is sleeved with a spring 207, one end of the spring 207 is fixedly connected to the corresponding round rod 206, and the other end of the spring 207 is fixedly connected to the support frame 2.

[0031] When the middle part of the plastic bag is pushed downward by the push plate 1 6, if the friction between one side of the plastic bag and the corresponding steel needle 4 is relatively large, due to the downward thrust applied by the push plate 1 6 to the middle part of the plastic bag, one side of the plastic bag will still be hanging on the steel needle 4, and the push plate 1 6 cannot push it off, thereby affecting the subsequent plastic particle feeding. Therefore, when the telescopic drive member 1 5 drives the push plate 1 6 to move downward, the push plate 1 6 pushes the push plate 2 205 to move downward, and the push plate 2 205 drives the round rod 206 to move downward and compresses the spring 207, so that the push plate 2 205 pushes the plastic bag hanging on the steel needle 4 downward. When in use, the push plate 1 6 and the push plate 2 205 cooperate to push the plastic bag hanging on the steel needle 4 downward, thereby avoiding the plastic bag hanging on one side on the steel needle 4, thereby avoiding the residual plastic bag affecting the grabbing of the next raw material package, and further avoiding the impact on the subsequent plastic particle feeding operation.

[0032] Implementation 3

[0033] Based on Implementation Plan 2, Figure 1 and Figure 2 As shown, it also includes a pushing assembly; the funnel 201 is connected to the pushing assembly; the pushing assembly includes a telescopic driving member 3 208 and a pushing plate 3 209; two telescopic driving members 3 208 are bolted to the funnel 201; the telescopic end of each telescopic driving member 3 208 is fixedly connected to two pushing plates 3 209, and the pushing plates 3 209 slide on the surface of the receiving plate 202, and the raw materials remaining on the surface of the receiving plate 202 are pushed into the funnel 201 through the pushing plates 3 209 to avoid residue.

[0034] The telescopic driving member 1 5, the telescopic driving member 203 and the telescopic driving member 3 208 are all configured as telescopic cylinders.

[0035] After the plastic particles fall to the upper side of the receiving plate 202, some of the plastic particles will remain on the upper side of the receiving plate 202 and cannot fall automatically, resulting in residue. Therefore, the telescopic driving member 208 is started, and the telescopic driving member 208 drives the push plate 209 to move, so that the push plate 209 pushes the plastic particles into the through hole of the receiving plate 202, and the plastic particles fall from the through hole into the funnel 201 to avoid residue.
