Description

Technical Field

[0001] The invention relates to the technical field of PET recycling, and in particular to a PET recycling and label removal device. Background Art

[0002] PET plastic bottles are not only widely used to package carbonated beverages, drinking water, juice, enzymes and tea beverages, and are the most widely used beverage packaging today, but are also widely used in many fields such as food, chemical, and pharmaceutical packaging. PET plastic has a wide range of applications in the packaging field. Whether it is packaging film, coils, or beer bottles, PET plastic is used. PET plastic bottles require the label paper on the PET plastic bottles to be peeled off during recycling operations.

[0003] However, currently on the market, a large number of labels on PET plastic bottles are removed manually, which is inefficient, complicated, and extremely inconvenient. There is an urgent need for a PET recycling and label removal device.

[0004] Therefore, we proposed a PET recycling and label removal device, which can remove labels from the surface of PET bottles, while ensuring the pre-treatment and transportation of PET bottles before label removal, and automating the processing of cut labels. This improves the degree of automation of the device while reducing the occurrence of malfunctions, improves the efficiency of label removal, and saves time and labor costs. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention provides a PET recycling and label removal device, comprising a hydraulic pump, a feed plate is fixedly installed at the bottom edge of the hydraulic pump, the PET recycling and label removal device also includes a limiting structure, the limiting structure is composed of a top ring plate, the top ring plate is arranged below the hydraulic pump, the outer surface of the top ring plate is fixedly connected to the outer ring plate, and the outer ring plate is arranged on the side of the top ring plate away from the hydraulic pump, the inner wall of the outer ring plate is fixedly installed with an upper connecting plate, and the upper connecting plate is arranged on the side of the outer ring plate close to the top ring plate, and the upper connecting plate is away from the outer ring plate. An inner ring plate is fixedly installed at one end of the ring plate, and a feeding structure is provided on the top of the inner ring plate. A label removal structure is provided inside the limiting structure, and the label removal structure is provided on the side of the outer ring plate away from the top ring plate. An arc-shaped groove is provided at the bottom of the limiting structure, and an arc-shaped groove plate is fixedly installed in the arc-shaped groove, and a waste receiving structure is slidably installed inside the arc-shaped groove plate, and the waste receiving structure is provided at the bottom end of the inner part of the outer ring plate. A collecting structure is fixedly installed on the outer surface of the outer ring plate, and the collecting structure is provided at the end of the outer ring plate away from the hydraulic pump.

[0006] Furthermore, a limiting bent plate is fixedly installed on the outer surface of the inner ring plate, and the limiting bent plate is fixedly installed on the end of the inner ring plate away from the top ring plate, and a lower connecting plate is fixedly installed on the outer surface of the limiting bent plate, and the end of the lower connecting plate away from the limiting bent plate is fixedly installed on the inner wall of the outer ring plate, the outer ring plate is connected to the inner ring plate through the lower connecting plate, and arc-shaped grooves are evenly opened on the bottom of the outer ring plate.

[0007] Furthermore, the inner wall of the inner ring plate is fixedly connected to the top ring plate, and a feed plate is fixedly installed on the top of the inner ring plate, and a hydraulic pump is fixedly installed on the top of the feed plate, and a telescopic rod is fixedly installed at the center of the bottom surface of the hydraulic pump, and an extrusion head is fixedly installed on the end of the telescopic rod away from the hydraulic pump. The PET bottle that needs to be de-labeled is put in from the upper side of the feed plate. The PET bottle slides downward into the inner ring plate under the influence of the inclination of the feed plate, ensuring that the PET bottle enters the device in a vertical state to facilitate subsequent de-labeling work. The PET bottle continues to slide downward in the inner ring plate. When the PET bottle slides into the limiting bent plate, the limiting bent plate has an arc shape, which enhances the wrapping effect on the PET bottle, so that the PET bottle slides downward vertically and stably, and the hydraulic pump is started, the telescopic rod extends downward, and the extrusion head collides with the PET bottle and applies a downward force to move the PET bottle downward.

[0008] Furthermore, arc-shaped slots are evenly opened on the bottom of the outer ring plate, arc-shaped slot plates are fixedly installed inside the arc-shaped slots, and connecting circular plates are fixedly installed at the intervals of the arc-shaped slots on the bottom of the outer ring plate.

[0009] Furthermore, a spring is fixedly mounted on a surface of the connecting circular plate away from the outer ring plate, and a fitting plate is fixedly mounted on an end of the spring away from the connecting circular plate.

[0010] Furthermore, a cutter head is fixedly installed on the top of the laminating plate, and the cutter head is arranged in the middle of the laminating plate, and guiding triangular blocks are fixedly installed on both sides of the top outer surface of the laminating plate, and shielding plates are fixedly installed on both sides of the top of the arc-shaped groove plate. After the PET bottle moves downward under the influence of the driving force and breaks away from the limit bending plate, it contacts the laminating plate. The laminating plate squeezes the PET bottle under the influence of the spring expansion and contraction to make the bottle body concave. After the PET bottle body is concave, the label on the surface is not affected. When the PET bottle continues to move downward, the label on the PET bottle body contacts the cutter head, and the cutter head cuts the label, thereby improving the automation level of the device and the efficiency of label removal. After the cut label contacts the guiding triangular block, it falls into the waste storage structure, and the shielding plate blocks the cut label to prevent the cut label from falling into the spring and winding around the spring, thereby improving the automation level of the device while reducing the occurrence of faults and improving the efficiency of label removal.

[0011] Furthermore, an arc-shaped pull-out box is slidably installed in the arc-shaped slot plate, an axis slot is provided in the middle of the top of the arc-shaped pull-out box, and a rotating shaft is rotatably installed in the axis slot.

[0012] The arc cover plate is closed when the drawer is pulled out to prevent the cut labels from flying out, thereby improving the working efficiency and saving time.

[0013] Furthermore, a collecting bin is fixedly installed at the bottom edge of the outer ring plate, a bin door is opened in the middle of the outer surface of the collecting bin, and a second handle is fixedly installed on the surface of the bin door. The PET bottles that have been stripped of the labels are pushed by the extrusion head and fall into the collecting bin. The second handle is pulled to open the bin door to recycle the PET bottles in the bin.

[0014] The present invention has the beneficial effects:

[0015] The present invention provides a PET recycling and labeling device. PET bottles that need to be labelled are placed in from the oblique upper part of a feed plate. The PET bottles are affected by the inclination of the feed plate and slide downward into the inner ring plate, ensuring that the PET bottles enter the device in a vertical state to facilitate subsequent labelling work. The PET bottles continue to slide downward in the inner ring plate. When the PET bottles slide into the limiting bent plate, the limiting bent plate has an arc shape, which enhances the wrapping effect on the PET bottles, so that the PET bottles slide downward in a vertical and stable manner. The hydraulic pump is started, the telescopic rod is extended downward, the extrusion head collides with the PET bottle and applies a downward force, so that the PET bottles move downward, and the PET bottles are controlled in a predetermined manner to ensure that they can perform labelling work stably, thereby improving the stability of the device.

[0016] The present invention provides a PET recycling and label removal device. After the PET bottle moves downward under the influence of a driving force and breaks away from a limiting bending plate, it contacts a bonding plate. The bonding plate is affected by the expansion and contraction of a spring to squeeze the PET bottle so that the bottle body is concave. After the PET bottle body is concave, the label on the surface is not affected. When the PET bottle continues to move downward, the label on the PET bottle body contacts a cutter head, which cuts the label, thereby improving the degree of automation of the device and the efficiency of label removal.

[0017] The present invention provides a PET recycling and label-removing device. After the cut labels contact the guiding triangle block, they fall into the waste storage structure. The shielding plate shields the cut labels to prevent the cut labels from falling into the spring and winding the spring. The automation degree of the device is improved, the occurrence of faults is reduced, and the efficiency of label removal is improved.

[0018] The present invention provides a PET recycling and label-removing device. A first handle is pulled to draw out an arc-shaped pull-out box. When the arc-shaped pull-out box is drawn out, the arc-shaped cover plate is subjected to the force of colliding with the outer ring plate and rotates through the rotating shaft. The arc-shaped cover plate automatically covers the arc-shaped pull-out box downward to prevent the cut labels in the box from flying out when the arc-shaped pull-out box is drawn out. After the waste in the arc-shaped pull-out box is cleaned up, the arc-shaped cover plate is closed and the arc-shaped pull-out box is placed in the arc-shaped slot plate. The top of the arc-shaped slot collides with the triangular rotating block. The pushing force causes the triangular rotating block to rotate through the rotating shaft. The arc-shaped cover plate at the bottom of the triangular rotating block rotates upward to automatically open the arc-shaped pull-out box. The arc-shaped pull-out box automatically opens in the outer ring plate for collection. When the pull-out box is drawn out, the arc-shaped cover plate is closed to prevent the cut labels from flying out, thereby improving work efficiency and saving time and cost.
