Description

Technical Field

[0001] The present application relates to the technical field of plastic products, and in particular to an edge processing device for processing plastic products. Background Art

[0002] Plastic products are a general term for daily necessities, industrial products, etc. made of plastic as the main raw material, including products made by all processes such as injection molding and blister molding using plastic as raw material.

[0003] An existing patent (publication number: CN 218746757 U) discloses a device for processing the edges of plastic products. The device includes an operating table, to which a first bearing and a second bearing are fixedly connected. A first rotating shaft is fixedly connected within the first bearing, and a second rotating shaft is fixedly connected within the second bearing. A first gear is fixedly connected to the first rotating shaft, and a second gear is fixedly connected to the second rotating shaft. The first and second gears engage with each other. A first clamping plate is fixedly connected to the upper end of the first rotating shaft, and a second clamping plate is positioned above the first clamping plate. This device adjusts the clamping plate to match the size of a circular plastic product. The clamping plate secures the circular plastic product, and the angle of rotation of the circular plastic product during polishing is fixed, allowing for uniform polishing of the edges and corners. Furthermore, when the polishing device is rotated, it drives the plastic product along with it, allowing single-handed polishing of the edges and corners, simplifying the polishing process.

[0004] The above-mentioned plastic product edge processing device can only perform grinding operations on circular plastic products of fixed sizes, has low flexibility and practicality, and cannot ensure that the circular plastic products are centered during grinding, which affects the grinding quality and may also cause damage to the plastic products. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present application provides an edge processing equipment for plastic product processing, which has the advantages of being able to grind and polish circular plastic products of different sizes, and facilitating the centering of circular plastic products to ensure the quality of grinding. It solves the problem that the existing plastic product edge processing device can only grind circular plastic products of fixed sizes, has low flexibility and practicality, and cannot ensure that the circular plastic products are centered during grinding, which affects the grinding quality and may also cause damage to the plastic products.

[0006] To achieve the above object, the present application provides the following technical solutions: A corner treatment device for plastic product processing, including an operating table, the bottom surface of the operating table is fixedly connected with a first motor, above the first motor is rotationally connected with a lower clamping plate through an output shaft, the upper surface of the operating table is fixedly connected with a bracket, the inside of the bracket is fixedly connected with a fixed seat, the inside of the fixed seat is rotationally inserted with a first control rod, the outer circumferential surface of the first control rod is threadedly connected with a lifting rod, and the outer circumferential surface of the lifting rod is rotationally sleeved with an upper clamping plate.

[0007] There are two slide rails on the bottom surface of the operating table, and a base is slidably connected between the two slide rails. The bottom surface of the base is fixedly connected with a second motor, above the second motor is rotationally connected with a grinding roller through an output shaft. The upper surface of the operating table is fixedly connected with a control box. The inside of the control box is rotationally inserted with a second control rod. The outer circumferential surface of the second control rod is threadedly connected with two threaded tubes. The outer circumferential surface of each threaded tube is fixedly connected with a connecting plate, and the front surface of the connecting plate is fixedly connected with a centering plate.

[0008] Through the above solution, since the existing corner treatment device for plastic products can only perform grinding operations on circular plastic products with fixed dimensions, the flexibility and practicality are relatively low, and it cannot ensure that the circular plastic products are centered during grinding, which affects the grinding quality and may also cause damage to the plastic products. By driving the base to move through an electric push rod, the horizontal distance between the grinding roller and the upper and lower clamping plates can be adjusted, so as to grind and process circular plastic products of different sizes. When the second control rod rotates, it drives the threaded tube to move inward, causing the connecting plate to drive the centering plate to move inward, so as to make the circular plastic products placed in the center and ensure the grinding quality.

[0009] Furthermore, a first anti-slip sheet is fixedly connected to the upper surface of the lower clamping plate, and a second anti-slip sheet is fixedly connected to the bottom surface of the upper clamping plate.

[0010] Through the above solution, the first anti-slip sheet and the second anti-slip sheet can increase the stability of positioning the circular plastic products and prevent the circular plastic products from easily shifting.

[0011] Furthermore, a first limiting ring is fixedly sleeved on the outer circumferential surface of the first control rod, and the outer circumferential surface of the first limiting ring is rotationally connected with the inside of the fixed seat.

[0012] Through the above solution, the first control rod is restricted to prevent the first control rod from sliding up and down, and the stability of the movement of the first control rod is increased.

[0013] Furthermore, two limiting plates are fixedly connected to the outer circumferential surface of the lifting rod, and the outer surface of each limiting plate is slidably connected with the fixed seat through an empty groove opened inside the fixed seat.

[0014] With the above solution, the lifting rod is restricted to prevent it from rotating following the first control rod, so as to ensure that the lifting rod always performs vertical lifting.

[0015] Furthermore, an electric push rod is fixedly connected to the bottom surface of the operating table, and the output end of the electric push rod is fixedly connected to the outer surface of the base.

[0016] With the above solution, the base is driven to move by the electric push rod, so that the horizontal distance between the grinding roller and the upper clamping plate and the lower clamping plate can be adjusted, and then circular plastic products of different sizes can be polished.

[0017] Furthermore, a second limiting ring is fixedly sleeved on the outer circumferential surface of the second control rod, and the outer circumferential surface of the second limiting ring is rotatably connected to the inside of the control box.

[0018] With the above solution, the second control rod is restricted to prevent it from sliding and shifting, and the stability of the movement of the second control rod is increased.

[0019] Furthermore, a limiting groove is provided inside the control box, and the outer surface of the connecting plate is slidably connected to the control box through the limiting groove.

[0020] With the above solution, the threaded pipe is restricted to prevent it from rotating following the second control rod, so as to ensure that the threaded pipe always performs lateral movement.

[0021] Furthermore, two threaded structures are provided on the outer circumferential surface of the second control rod, and the threaded track directions of the two threaded structures on the outer circumferential surface of the second control rod are opposite.

[0022] With the above solution, the threaded pipe can move in opposite directions, and then the centering plate can move in opposite directions, completing the centering operation of the circular plastic product.

[0023] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0024] For this plastic product processing corner treatment device, the base is driven to move by the electric push rod, so that the horizontal distance between the grinding roller and the upper clamping plate and the lower clamping plate can be adjusted. When the second control rod rotates, it drives the threaded pipe to move inward, and the connecting plate drives the centering plate to move inward, achieving the effect of being able to polish circular plastic products of different sizes and facilitating the centering placement of circular plastic products, ensuring the polishing quality, and solving the problem that the existing plastic product corner treatment device can only polish circular plastic products of a fixed size and cannot ensure the centering setting of circular plastic products during polishing, affecting the polishing quality.
