Description

Technical Field

[0001] This utility model relates to the field of polishing technology for plastic products, specifically a polishing mechanism for injection molded products. Background Technology

[0002] After injection molding, the surface of plastic products is not smooth enough. Polishing machines are needed to polish the plastic products to improve their gloss or transparency and thus improve their quality.

[0003] In related technologies, a solution for a polishing device for injection molded products (announcement number CN222308434U) was found. The injection molded product is placed between two clamping plates. The output end of the cylinder extends and retracts to control the connecting plate to move the docking plate. The docking plate can move the movable plate, thereby pushing and polishing the injection molded product. At the same time, the operator holds and pulls the lever to rotate the rotating shaft. The rotation of the rotating shaft can drive the clamping plate to rotate, and then the injection molded product to rotate. This allows different surfaces of the injection molded product to be matched with the polishing wheel for polishing operations.

[0004] However, the above solution relies on manual operation for clamping injection molded products, and there is a risk of hand injury when operating the lever during polishing. Since the injection molded product is directly below the polishing wheel, the operating space is limited and inconvenient when applying polishing wax. The polishing wheel size is fixed, making it difficult to polish different injection molded products. Utility Model Content

[0005] The purpose of this invention is to provide a polishing mechanism for injection molded products to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a polishing mechanism for injection molded products, including a support frame, a top frame fixedly connected to the support frame, a conveyor installed on the inner wall of the support frame and the top frame, a first cylinder installed on the top frame, the conveyor can automatically transport injection molded products, reduce manual operation, and make product transportation safer;

[0007] The motor is connected to the first cylinder. The motor is connected to a polishing pad through an eccentric mechanism. The eccentric mechanism controls the translation of the polishing pad. The polishing pad polishes the injection molded product. The translation of the polishing pad can increase the polishing range and can adapt to injection molded products of different sizes.

[0008] The wax spraying tube is installed on the bracket and conveyor. The wax spraying tube automatically sprays polishing wax onto the product to improve the polishing effect, eliminating the need for manual application of polishing wax.

[0009] Furthermore, the conveyor includes a second cylinder and a mounting frame connected to the second cylinder. An electric roller is mounted on the mounting frame, and an electric roller is also mounted on the inner wall of the support. The upper and lower rows of electric rollers can convey and clamp the plastic product, automatically delivering the plastic product to the location of the polishing pad.

[0010] Furthermore, a fixing frame is connected to the lower surface of the bracket, and the fixing frame is also equipped with a first cylinder, a motor, an eccentric mechanism, and a polishing pad, so as to realize double-sided polishing of the product and improve polishing efficiency.

[0011] Furthermore, the eccentric mechanism includes a slide rail and a slide block that slides with the slide rail. The polishing pad is connected to the lower surface of the slide block, and the surface of the slide block is screwed with bolts that hold the slide rail in place. Loosening the bolts can quickly change the position of the polishing pad, making the operation simple.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] (1) The injection molded product is placed on the electric roller, and the second cylinder controls the upper electric roller to move down and clamp the injection molded product. The rotation of the electric roller controls the automatic clamping and transportation of the injection molded product. No manual operation is required, making it safer to polish the injection molded product.

[0014] (2) When the electric roller transports the injection molded products, the wax spray tube automatically sprays polishing wax onto the injection molded products, avoiding manual application and improving the polishing effect of the injection molded products.

[0015] (3) Tightening the bolts can slide and adjust the position of the slide block, thereby changing the position of the polishing pad, so that the polishing pad rotates eccentrically, which can increase the polishing range and is suitable for injection molded products of different sizes.

[0016] (4) The upper and lower polishing pads realize double-sided polishing of injection molded products, improve the polishing efficiency of injection molded products, and complete the polishing of injection molded products in one go. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figure 1-4 This utility model provides a technical solution: a polishing mechanism for injection molded products, including a support 1, a top frame 2 fixedly connected to the support 1, a conveyor installed on the inner wall of the support 1 and the top frame 2, the conveyor automatically transports the injection molded products, and a first cylinder 3 installed on the top frame 2, the first cylinder 3 controlling the raising and lowering of the polishing pad 5, which can polish injection molded products of different thicknesses;

[0025] Motor 4 is connected to the first cylinder 3. Motor 4 is connected to polishing pad 5 through an eccentric mechanism. The eccentric mechanism controls the translation of polishing pad 5 to realize the eccentric adjustment of polishing pad 5 and expand the polishing range of polishing pad 5. It can be used according to needs to meet the polishing of injection molded products of different widths.

[0026] The wax spraying tube 10 is installed on the bracket 1 and the conveyor. The wax spraying tube 10 sprays polishing wax onto the product. It is suitable for liquid or high-strength polishing wax. It is convenient to use a pump to supply polishing wax to the wax spraying tube 10. Several wax spraying tubes 10 are provided and equipped with valves. The required number of wax spraying tubes 10 can be determined according to the width of the injection molded product to avoid wasting polishing wax.

[0027] In this embodiment, as Figure 1 and Figure 2 As shown, the conveyor includes a second cylinder 7 and a mounting frame 8 connected to the second cylinder 7. An electric roller 9 is mounted on the mounting frame 8, and an electric roller 9 is also mounted on the inner wall of the support 1. The surface of the electric roller 9 is covered with a soft rubber sleeve, which provides flexible contact when clamping the injection molded product to avoid damage to the injection molded product. The soft rubber sleeve has a good anti-slip effect and can prevent the injection molded product from shifting when grinding the injection molded product. The second cylinder 7 controls the lifting and lowering of the electric roller 9 through the top frame 2 to realize the clamping and conveying of the injection molded product.

[0028] In this embodiment, as Figure 1 and Figure 2 As shown, two positioning components are installed on the bracket 1. The product moves from between the two positioning components toward the conveyor, which can prevent the injection molded product from shifting and ensure that the injection molded product moves stably toward the upper and lower rows of electric rollers 9.

[0029] In this embodiment, as Figure 1 and Figure 2 As shown, the positioning component includes a screw 12, which is screwed to the bracket 1. The screw 12 is rotatably connected to a positioning plate 11. Tightening the screw 12 can push the positioning plate 11 to move, and the distance between the two positioning plates 11 can be changed according to the width of the injection molded product.

[0030] In this embodiment, as Figure 2 As shown, the right side of the inner wall of the bracket 1 is connected to several receiving rods 17. The receiving rods 17 are thin and polished to reduce the friction of the receiving rods 17. They can support the polished injection molded products. The thinner receiving rods 17 are less likely to leave scratches on the injection molded products.

[0031] In this embodiment, as Figure 1 As shown, a fixed frame 6 is connected to the lower surface of the bracket 1. The fixed frame 6 is also equipped with a first cylinder 3, a motor 4, an eccentric mechanism, and a polishing pad 5 to achieve double-sided polishing of the product. When polishing of the injection molded product is not required, the first cylinder 3 controls the polishing pad 5 to move down and will not come into contact with the injection molded product.

[0032] In this embodiment, as Figure 3 and Figure 4 As shown, the eccentric mechanism includes a slide rail 13 and a slide block 15 that slides in contact with the slide rail 13. The polishing pad 5 is connected to the lower surface of the slide block 15. Bolts 16 that press against the slide rail 13 are screwed onto the surface of the slide block 15. A transmission sleeve 14 is connected to the upper side of the slide rail 13. Tightening the two bolts 16 can quickly change the eccentricity of the polishing pad 5, which is convenient to operate. The transmission sleeve 14 is connected to the motor 4. The transmission sleeve 14 has a pin hole to ensure that the connection between the transmission sleeve 14 and the motor 4 is stable and the power transmission is better.

[0033] Specifically, during use, the injection molded product is pushed from between the two positioning plates 11 onto the lower electric roller 9. The second cylinder 7 controls the upper electric roller 9 to move down and clamp the injection molded product. The upper and lower rows of electric rollers 9 rotate to move the injection molded product toward the polishing pad 5. When the injection molded product passes through the wax spray pipe 10, the wax spray pipe 10 sprays polishing wax onto the upper and lower surfaces of the injection molded product. The first cylinder 3 controls the polishing pad 5 to approach the injection molded product, and the motor 4 controls the polishing pad 5 to rotate so that the polishing wax can be spread evenly, achieving double-sided polishing of the injection molded product. Moreover, the rotation direction of the electric roller 9 is different, so the injection molded product can be polished repeatedly.

[0034] When adjusting the eccentric position of the polishing pad 5, first tighten the bolt 16, then slide the slide block 15 on the slide rail 13. The slide block 15 drives the polishing pad 5 to move horizontally, which can expand the polishing range of the polishing pad 5 and make it flexible and convenient to use.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
