Description

Technical Field

[0001] The present application relates to the technical field of plastic product production and processing, and specifically discloses a plastic product processing device. Background Art

[0002] In the industrial production of plastic products, the production system of plastic products is mainly composed of four continuous processes: plastic molding, mechanical processing, decoration and assembly.

[0003] Take plastic baskets as an example. After forming, they need to be deburred, burred, and corrected in size, and then painted and colored. Painting mainly involves applying paint to the surface of the product, using solvents to brighten the surface, and using patterned films to cover the surface of the product. Coloring includes painting, printing, and hot stamping. After the plastic baskets are painted, colored, and processed, they need to be cleaned to facilitate the adhesion of the paint and to remove dirt that adheres during the processing or in the production workshop.

[0004] At present, the cleaning of plastic frames is mainly done manually, that is, the operator uses a high-pressure spray gun to rinse the plastic frame. Not only is the working environment poor, the labor intensity is high, and the cleaning time is long; but also when the high-pressure water flow impacts the plastic frame, it is easy to cause the plastic frame to shift and affect the cleaning effect. Usually, the plastic frame needs to be fixed manually, which further increases the difficulty of cleaning. Therefore, in view of this, the present invention provides a plastic product processing device to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to solve the problem that traditional plastic products such as plastic frames rely on operators to hold high-pressure spray guns for washing, resulting in poor working environment, high labor intensity and long cleaning time.

[0025] The cleaning mechanism further comprises a second water sprinkling plate, which is located on a side wall away from the first water sprinkling plate and is connected to the water inlet pipe.

[0026] Furthermore, the second watering plate is an arc-shaped plate, and the connecting frame includes an arc-shaped plate rotatably connected to the second watering plate and a bracket connecting the arc-shaped plate and the rotating disk.

[0027] Furthermore, the limit block is also connected to a limit rod, the limit rod passes through the arc plate, and the second sprinkler plate is provided with a limit hole into which the end of the limit rod can be inserted.

[0031] Furthermore, the connecting shaft is a hollow shaft, the nozzle is arranged at the bottom end of the connecting shaft, and a connecting ring is provided on the connecting shaft which is rotatably and sealingly connected to the rotating sleeve.

[0032] The principle and effect of this scheme are:

[0033] 1. The present invention provides a clamping mechanism so that when the water supply pump supplies water to the water inlet pipe so that the nozzle cleans the plastic frame and other plastic products, the water flow is also introduced into the regulating box, and the high-pressure water flow is used to drive the slide plate to slide, thereby driving the slide plate and the push rod to move, so that the end of the push rod is in close contact with the surface of the plastic frame and other plastic products to be cleaned, so that the two clamping mechanisms can achieve the effect of clamping the plastic frame and other plastic products, so as to avoid the problem that the plastic frame and other plastic products are displaced due to the impact of the water flow, resulting in poor cleaning effect; and the reset component is used to drive the slide plate and the push rod to reset after cleaning is completed, so as to release the clamping effect on the plastic frame and other plastic products.

[0034] 2. The present invention provides a hollow push rod and a first water sprinkling plate, etc., so that after the water flow is introduced into the regulating box, the surface of plastic products such as plastic frames is also rinsed through the push rod and the first water sprinkling plate. At the same time, it is also convenient to discharge the water flow in the regulating box in time after cleaning is completed, so that the reset spring can drive the slide plate and the push rod to reset.

[0035] 3. The setting of the conversion mechanism in the present invention allows water to flow into the conversion chamber after the plastic frame and other plastic products are clamped, driving the rotating disk, the connecting frame and the clamping mechanism to rotate as a whole, thereby driving the plastic frame and other plastic products to rotate as a whole, so that the position of the plastic frame changes. In this state, the first sprinkler plate can directly flush two side surfaces of the plastic frame and other plastic products, and the second sprinkler plate can directly flush the other two side surfaces of the plastic frame and other plastic products, thereby completing the flushing of the four side surfaces of the plastic frame and other plastic products. After the flushing is completed, the torsion spring drives the rotating disk to reset, that is, the clamping mechanism and the plastic frame and other plastic products are reset, without interfering with the normal conveying process of the plastic frame and other plastic products by the roller conveyor.

[0036] 4. Compared with the prior art, the present invention can automatically clamp plastic frames and other plastic products and flush all sides, which can replace the existing manual cleaning process and effectively solve the problem that traditional plastic frames and other plastic products rely on operators to hold high-pressure spray guns for flushing, resulting in poor working environment, high labor intensity and long cleaning time.

DETAILED DESCRIPTION

[0046] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0047] A plastic product processing device, for example Figure 1 As shown: it includes a cleaning box 3 and a roller conveyor 2 that penetrates the cleaning box 3 and is used to convey the plastic frame 1. The cleaning box 3 has a box body located above the roller conveyor 2 and a box body located below the roller conveyor 2. The box body of the cleaning box 3 located above the roller conveyor 2 is used to clean the plastic frame 1 entering the cleaning box 3, and the box body of the cleaning box 3 located below the roller conveyor 2 is used to collect the cleaning liquid, water flow, etc. used in the cleaning process and discharge them through the drainage pipe.

[0048] like Figure 2 and Figure 3 As shown, a cleaning mechanism, a conversion mechanism and a clamping mechanism are respectively arranged inside the cleaning box 3. The cleaning mechanism includes a water inlet pipe 4 arranged at the top of the cleaning box 3, a water supply pump arranged outside the cleaning box 3 and connected to the water inlet pipe 4, a nozzle 19 supplying water through the water inlet pipe 4, two symmetrically arranged first water sprinkling plates 15 and two symmetrically arranged second water sprinkling plates 11.

[0049] like Figure 2 and Figure 3 As shown, the conversion mechanism includes a fixed cylinder 5 installed at the top of the cleaning box 3, a water inlet jacket 16 located in the fixed cylinder 5, a rotating disk 22 rotatably connected to the bottom of the inner wall of the fixed cylinder 5, and a sealing plate 20 arranged in the fixed cylinder 5. The top of the water inlet jacket 16 is connected to the water inlet pipe 4 through a connecting flange 8. Figure 3As shown, the rotating disk 22 is provided with a connecting sleeve 23 that is rotatably sealed with the outer wall of the water inlet sleeve 16, and the sealing plate 20 divides the fixed cylinder 5 into an upper cavity and a lower cavity. The lower cavity is connected to the first sprinkler plate 15 through a first water supply pipe, and the upper cavity is connected to the second sprinkler plate 11 through a second water supply pipe. Four fixed plates 21 are provided at the bottom of the sealing plate 20, and correspondingly, two rotating plates 24 are provided on the rotating disk 22. The adjacent fixed plates 21, rotating plates 24, rotating disk 22, connecting sleeves 23, and fixed cylinders are connected to each other. 5 inner wall and the bottom of the sealing plate 20 form a conversion cavity, the connecting sleeve 23 is provided with a guide hole 27 communicating with the conversion cavity, and the side wall of the water inlet sleeve 16 is provided with a water inlet hole 26 communicating with the guide hole 27, and the sealing plate 20 is provided with a water guide groove 28 that can connect the upper cavity with the lower cavity, and the water guide groove 28 and the initial position of the rotating plate 24 present an angle of 90°, so that after the rotating plate 24 rotates to an angle of 90°, the water guide groove 28 connects the conversion cavity with the upper cavity, and the water flows into the upper cavity and the second sprinkler plate 11. The fixed plate 21 on the right side limits the rotation position of the rotating plate 24 to prevent the rotating arc of the rotating plate 24 from being too large.

[0050] by Figure 3 For example, a conversion chamber is formed between the rotating plate 24 on the front side and the fixed plate 21. When the water inlet pipe 4 supplies water to the water inlet sleeve 16, the water flows into the conversion chamber through the water inlet hole 26 on the side wall of the water inlet sleeve 16 and the guide hole 27 on the connecting sleeve 23. The water pressure causes the rotating plate 24 to rotate to the right, and after rotating to an angle of 90°, the conversion chamber is connected to the upper cavity to realize water supply to the second sprinkler plate 11.

[0051] The top of the water inlet sleeve 16 is connected to the water inlet pipe 4, and the bottom of the water inlet sleeve 16 extends out of the bottom of the fixed cylinder 5 and is installed with a hollow connecting shaft 17. Correspondingly, a rotating sleeve 25 located at the outer end of the connecting shaft 17 is installed at the bottom of the rotating disk 22. A torsion spring 18 is arranged between the rotating sleeve 25 and the connecting shaft 17. The torsion spring 18 is respectively connected to the rotating sleeve 25 and the connecting shaft 17. A sealing ring is provided on the connecting shaft 17 to rotate and seal with the rotating sleeve 25 to prevent the water flow from connecting with the connecting shaft 17. The spray head 19 adopts a spherical spray head 19 and is arranged at the bottom end of the connecting shaft 17.

[0052] like Figure 2 and Figure 4 As shown, the second sprinkler plate 11 is an arc-shaped plate 10, and is installed in the cleaning box 3 through a mounting seat 12. A guide bar 13 is also provided at the end of the second sprinkler plate 11 close to the feeding end of the roller conveyor 2, and a plurality of balls 14 are provided on the surface of the guide bar 13. The connecting frame includes an arc-shaped plate 10 rotatably connected to the second sprinkler plate 11 and a bracket 9 connecting the arc-shaped plate 10 and the rotating disk 22.

[0053] like Figure 4 , Figure 5 and Figure 6 As shown, the clamping mechanism includes an adjustment box 32 disposed on the side of the first water spraying plate 15 close to the arc plate 10, a slide plate 35 slidably connected in the adjustment box 32, a stopper 33 disposed on the slide plate 35 and extending out of the adjustment box 32, and a reset component for driving the slide plate 35 to reset. Figure 4 As shown, the reset assembly includes a guide rod connected to the slide plate 35 and extending out of the end of the adjustment box 32, a limit block 29 provided at one end of the guide rod extending out of the adjustment box 32, and a reset spring 30 provided between the limit block 29 and the adjustment box 32. The limit block 29 is also connected to a limit rod 31, which passes through the arc plate 10. The arc plate 10 is provided with a corresponding through hole 34 to allow the limit rod 31 to pass through, and the second sprinkler plate 11 is provided with a limit hole to allow the end of the limit rod 31 to be inserted, and one side end of the limit rod 31 is provided with an inclined surface to facilitate sliding into the limit hole during reset.

[0054] like Figure 6 As shown, the stopper 33 is a hollow rod, and a water sprinkling cavity is provided in the first water sprinkling plate 15. The slide plate 35 divides the regulating box 32 into a first cavity communicating with the inside of the stopper 33 and a second cavity communicating with the water sprinkling cavity. Since there are five stopper rods 33 in this embodiment, the end of the middle stopper rod 33 is covered by the guide rod, which affects the water supply. In this embodiment, a water guide rod 37 is used to connect the stopper rod 33 and the guide rod. Figure 7 As shown, one end of the water guiding rod 37 is connected to the guide rod through the connecting block 36, and the other end of the water guiding rod 37 is directly connected to the support rod 33. A water channel connected to the support rod 33 is provided inside the water guiding rod 37, and a water guide hole 39 connected to the first cavity and the water channel is provided on the surface of the water guiding rod 37.

[0055] like Figure 6 As shown, a plurality of fixed rods 38 penetrating the first cavity and the second cavity are provided in the regulating box 32, a water channel is also provided inside the fixed rod 38, and a plurality of water guide holes 39 are also provided on the side wall of the fixed rod 38. When no water is supplied, the water guide holes 39 on the side wall of the fixed rod 38 are all connected with the second cavity. When water flows into the regulating box 32 and drives the slide plate 35 to move, some of the water guide holes 39 on the side wall of the fixed rod 38 are connected with the first cavity, and some of the water guide holes 39 are connected with the second cavity, so that the first cavity and the second cavity are connected, that is, water supply to the first sprinkler plate 15 is realized.

[0056] In this embodiment, the operator places the plastic frame 1 to be cleaned on the roller conveyor 2, and the various rollers in the roller conveyor 2 rotate under the drive of the motor to drive the plastic frame 1 to move, so that the plastic frame 1 enters the cleaning box 3. When the plastic frame 1 enters the cleaning box 3, the cleaning liquid or water flow supplied by the water supply pump first passes through the water inlet sleeve 16, the conversion chamber, the first water supply pipe 7 and enters the first cavity. The cleaning liquid or water flow pushes the slide plate 35 in the regulating box 32 to move and part of the water flow flows out from the push rod 33, thereby cleaning some points of the plastic frame 1. At this time, the end of the limit rod 31 is inserted into the limit hole, and the arc plate 10 and the second sprinkler plate 11 cannot rotate relative to each other. The slide plate 35 drives the push rod 33 to move toward the plastic frame 1, so that the end of the push rod 33 is close to the surface of the plastic frame 1, and the push rods 33 on both sides cooperate with each other to achieve the effect of clamping the plastic frame 1; at the same time, the water guide hole 39 on the fixed rod 38 connects the first cavity with the second cavity to realize water supply to the first sprinkler plate 15; at this time, the end of the limit rod 31 is separated from the limit hole, and the water flow enters the conversion chamber and drives the rotating plate 24 to rotate, so that the rotating disk 22, the connecting frame and the clamping mechanism are rotated as a whole, and then drives the plastic frame 1 to rotate. After rotating to an angle of 90°, the conversion chamber is connected with the upper cavity to realize water supply to the second sprinkler plate 11, and the four sides of the plastic frame 1 can be flushed. After the flushing is completed, the reset spring 30 and the torsion spring 18 respectively drive the rotating disk 22 and the slide plate 35 to reset, release the clamping effect on the plastic frame 1, and the roller conveyor 2 transports the cleaned plastic frame 1 to the outside of the cleaning box 3.

[0057] The present embodiment can automatically clamp plastic products such as the plastic frame 1 and flush all sides, and can replace the existing manual cleaning process, effectively solving the problem that traditional plastic products such as the plastic frame 1 rely on operators to hold a high-pressure spray gun for flushing, resulting in a poor working environment, high labor intensity, and long cleaning time.

[0058] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any indirect modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
