Description

[0002] Rubber and plastics is a general term for the rubber and plastics industries, both of which are byproducts of petroleum. Plastics and rubber both belong to polymer materials, mainly composed of carbon and hydrogen atoms.

[0003] After molding, rubber and plastic parts often have excess flash, burrs, or excess material remaining on their edges or surfaces (e.g., oil seals). These flashes not only affect the product's appearance but can also reduce assembly accuracy and performance, thus requiring trimming. Currently, depending on the workpiece size, trimming methods for rubber and plastic parts mainly include manual trimming, mechanical trimming, and cryogenic trimming. However, in mechanical trimming, because the rubber and plastic parts need to be fixed by adsorption, the workpiece must be manually placed on a vacuum adsorption plate, and then manually removed after processing. This manual operation not only increases the workload of workers but also reduces trimming efficiency. Summary of the Invention

Detailed Implementation

[0020] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0021] The following description, in conjunction with the accompanying drawings, describes a rubber and plastic parts production trimming apparatus according to an embodiment of this application.

[0022] like Figures 1-6 As shown, the rubber and plastic parts production trimming device of this application embodiment may include a worktable 1, and a shifting mechanism 2, a feeding mechanism 3, a trimming mechanism 4 and a unloading assembly 5 installed on the worktable 1.

[0023] It should be noted that the workbench 1 described in the above embodiment is provided with a conveyor belt (not shown in the figure) on one side of the unloading component 5, and realizes the unloading of the rubber and plastic parts after the trimming is completed and transports them to the next process for processing.

[0024] The displacement mechanism 2 may include a placement component 21, a support plate 22, a driving component 23, and an adsorption component 24.

[0025] It should be noted that the adsorption component 24 described in the above embodiments is connected to an external vacuum pump (not shown in the figure).

[0026] The placement component 21 is rotatably mounted on the workbench 1 via the support plate 22, the drive component 23 is set on the workbench 1 and is connected to the placement component 21 in a transmission manner, and the adsorption component 24 is mounted on the workbench 1.

[0027] Understandably, the rubber and plastic parts are placed by the placement component 21, and then rotated by the drive component 23. The rubber and plastic parts are then moved to the underside of the trimming mechanism 4 for processing. Before processing, the rubber and plastic parts on the placement component 21 are adsorbed and fixed by the adsorption component 24, thereby preventing the rubber and plastic parts from sliding during the trimming process.

[0028] Specifically, such as Figure 3 As shown, the placement component 21 may include a rotating plate 211, an adsorption toothed platform 212, a top plate 213, and a limiting plate 214.

[0029] It should be noted that the adsorption platform 212 described in the above embodiment has multiple adsorption holes, and the adsorption holes are interconnected, so that the adsorption assembly 24 can complete the adsorption and fixation of the rubber and plastic parts through the adsorption holes.

[0030] The rotating plate 211 is rotatably mounted on the support plate 22, the adsorption tooth platform 212 is rotatably mounted on the top plate 213, the top plate 213 is slidably connected to the rotating plate 211, and the limiting plate 214 is mounted on both sides of the top plate 213.

[0031] Understandably, the installation of the rotating plate 211 is completed under the action of the support plate 22. Then, the feeding mechanism 3 places the rubber and plastic parts on the adsorption tooth table 212. Then, under the rotation of the rotating plate 211, the rubber and plastic parts on the adsorption tooth table 212 are moved to the bottom of the trimming mechanism 4. Then, under the action of the adsorption component 24, the adsorption tooth table 212 is lifted up and comes into contact with the trimming mechanism 4. At the same time, the adsorption component 24 fixes the rubber and plastic parts through the adsorption holes on the adsorption tooth table 212, thereby facilitating the trimming mechanism 4 to trim the rubber and plastic parts.

[0032] Specifically, such as Figure 3 As shown, the drive assembly 23 includes a drive motor 231, a transmission rod 232, and a transmission gear rod 233.

[0033] The drive motor 231 is mounted on the workbench 1, the transmission rod 232 is connected to the output end of the drive motor 231, the transmission gear rod 233 is rotatably mounted on the support plate 22, the transmission gear rod 233 is connected to the transmission rod 232, and the transmission gear rod 233 is connected to the rotating plate 211.

[0034] Understandably, the drive motor 231 and the transmission rod 232 drive the transmission gear rod 233 to rotate, and during the rotation, the transmission gear rod 233 drives the rotating plate 211 to rotate on the worktable 1, thereby completing the movement of the adsorption gear table 212 and the rubber and plastic parts, thus ensuring the continuity of the rubber and plastic parts in the processing, thereby achieving the effect of improving processing efficiency.

[0035] Specifically, such as Figure 3 As shown, the adsorption assembly 24 may include a cylinder 241, an air extraction box 242, and an adsorption tube 243.

[0036] It should be noted that the vacuum box 242 described in the above embodiment is equipped with multiple limiting rods, and the top plate 213 is provided with insertion holes for the limiting rods to be inserted, so as to avoid the top plate 213 from rotating together when the adsorption tooth table 212 rotates, thus avoiding the impact on the adsorption and fixation of the rubber and plastic parts.

[0037] The cylinder 241 is installed on the workbench 1, the suction box 242 is installed on the extended end of the cylinder 241, the adsorption tube 243 is connected to the suction box 242, and the adsorption tooth platform 212 and the top plate 213 are provided with through holes for the adsorption tube 243 to pass through.

[0038] Understandably, the height of the suction box 242 and the adsorption tube 243 is adjusted by the action of the cylinder 241. Then, the suction box 242 abuts against the top plate 213, forcing the top plate 213 to drive the adsorption tooth table 212 to rise and contact the trimming mechanism 4, which facilitates the rotation of the adsorption tooth table 212 by the trimming mechanism 4. Then, under the action of the adsorption tube 243, the rubber and plastic parts on the adsorption tooth table 212 are adsorbed and fixed, thereby preventing the rubber and plastic parts from shaking and falling off the adsorption tooth table 212 during the processing.

[0039] The feeding mechanism 3 may include a mounting frame 31, a toothed plate 32, a material cylinder 33, a linkage assembly 34, and a feeding assembly 35.

[0040] It should be noted that the bottom end of the barrel 33 described in the above embodiment is equipped with multiple support rods to support the rubber and plastic parts inside the barrel 33.

[0041] The mounting frame 31 is mounted on the workbench 1, the toothed plate 32 and the material cylinder 33 are respectively mounted on the toothed plate 32, the linkage component 34 is rotatably mounted on the workbench 1, the feeding component 35 is rotatably mounted on the mounting frame 31, and the drive component 23 is connected to the feeding component 35 through the linkage component 34. One end of the feeding component 35 is engaged with the toothed plate 32.

[0042] It is understandable that stacked rubber and plastic parts are placed inside the material cylinder 33, and then driven by the drive component 23 in the linkage component 34. When rotating, the linkage component 34 drives the feeding component 35 to move up and down in the mounting frame 31, thereby sucking out the rubber and plastic parts in the material cylinder 33 and placing them on the adsorption tooth table 212, thus completing the feeding of the rubber and plastic parts.

[0043] Specifically, such as Figure 4 As shown, the linkage component 34 includes a servo motor 341, a rotating ring 342, and a linkage rod 343.

[0044] It should be noted that when the servo motor 341 described in the above embodiment drives the feeding assembly 35 to rise and fall through the rotating ring 342 and the linkage rod 343, the rotating plate 211 rotates by one-quarter.

[0045] The servo motor 341 is mounted on the worktable 1. The output end of the servo motor 341 is connected to the rotating ring 342 for transmission. The rotating ring 342 is rotatably mounted on the worktable 1. The linkage rod 343 is mounted on the rotating ring 342 and passes through the worktable 1 and is connected to the feeding assembly 35.

[0046] Understandably, when the drive component 23 rotates, the servo motor 341 drives the rotating ring 342, the linkage rod 343 and the feeding component 35 to rotate, thereby realizing the adsorption and feeding of the rubber and plastic parts in the material cylinder 33.

[0047] Specifically, such as Figure 4 As shown, the feeding assembly 35 may include a lead screw 351, a slide table 352, a fixing frame 353, a tilting gear 354, and an adsorption component 355.

[0048] It should be noted that the adsorption element 355 described in the above embodiment is connected to a vacuum pump (not shown in the figure) to achieve adsorption and feeding of the rubber and plastic parts in the material cylinder 33.

[0049] It should be noted that when the drive assembly 23 drives the rotating plate 211 to rotate a quarter turn, the slide table 352 reciprocates once on the lead screw 351, thereby ensuring that the rubber and plastic parts can fall directly onto the adsorption tooth table 212 during the feeding process, ensuring the continuity of the feeding process.

[0050] Among them, the lead screw 351 is connected to the linkage rod 343, the slide 352 is threaded on the outside of the lead screw 351, and the two sides of the slide 352 are in contact with the mounting bracket 31. The fixed bracket 353 is rotatably mounted on the slide 352, the flip gear 354 is rotatably mounted on the slide 352, and the flip gear 354 is connected to the fixed bracket 353 through a universal joint. The adsorption component 355 is mounted on the fixed bracket 353.

[0051] Understandably, after the lead screw 351 is driven by the linkage rod 343, it drives the slide table 352 to move up and down in the mounting frame 31. Then, during the up and down movement of the slide table 352, the flip gear 354 meshes with the toothed plate 32 and drives the flip gear 354 to rotate. When the flip gear 354 rotates, it changes the orientation of the adsorption end of the adsorption member 355 through the universal joint, so that the adsorption end of the adsorption member 355 faces the material cylinder 33. When the slide table 352 continues to rise, the adsorption member 355 comes into contact with the rubber and plastic part and completes the adsorption effect. Due to the plasticity of the rubber and plastic part, the rubber and plastic part bends around its perimeter, thus being sucked out of the material cylinder 33. Subsequently, the linkage assembly 34 drives the lead screw 351 to rotate in the opposite direction. When rotating, the slide table 352 descends, and the flip gear 354 comes into contact with the toothed plate 32 to change the orientation of the adsorption end of the adsorption member 355, so that the adsorption member 355 can place the rubber and plastic part on the adsorption toothed table 212, thereby achieving the effect of feeding the rubber and plastic part.

[0052] The above-described implementation method can automatically complete the loading and unloading of rubber and plastic parts during the trimming process and simultaneously clean up trimming waste, thereby reducing the workload of workers and effectively improving trimming efficiency.

[0053] In one embodiment of this application, such as Figure 5 As shown, the trimming mechanism 4 may include a trimming component 41 and a transmission component 42.

[0054] It should be noted that the trimming component 41 described in the above embodiments is prior art, so it will not be described in detail.

[0055] The trimming assembly 41 is mounted on the workbench 1, and the transmission assembly 42 is mounted on the trimming assembly 41.

[0056] Understandably, the trimming assembly 41 completes the trimming process of the rubber and plastic parts, and under the drive of the transmission assembly 42, the adsorption tooth table 212 drives the rubber and plastic parts to rotate, thereby facilitating the trimming process around the rubber and plastic parts.

[0057] Furthermore, such as Figure 4 As shown, the trimming assembly 41 may include a mounting frame 411, a travel screw 412, a slide plate 413, and a trimming machine 414.

[0058] The mounting frame 411 is mounted on the workbench 1, the travel screw 412 is rotatably mounted on the mounting frame 411, the slide plate 413 is threaded onto the travel screw 412, and the trimming machine 414 is mounted on the slide plate 413.

[0059] It should be noted that the mounting frame 411 described in the above embodiments is driven by a geared motor (not shown in the figure), and the angle and height of the trimming machine 414 can be adjusted.

[0060] Furthermore, such as Figure 4 As shown, the transmission assembly 42 may include a transmission motor 421 and a meshing gear 422.

[0061] The drive motor 421 is mounted on the mounting frame 411, and the meshing gear 422 is connected to the output end of the drive motor 421.

[0062] It should be noted that, after the adsorption toothed platform 212 described in the above embodiment is lifted by the adsorption component 24, it meshes with the meshing gear 422, so that during the trimming process, the adsorption toothed platform 212 and the rubber and plastic parts are driven to rotate by the drive motor 421 through the meshing gear 422.

[0063] Understandably, driven by the drive motor 421, the adsorption assembly 24 pushes the raised adsorption tooth platform 212 to be driven by the meshing gear 422 and rotates at a high speed. At the same time, before trimming, the angle and height of the trimming machine 414 on the mounting frame 411 are adjusted according to the height of the rubber and plastic parts to ensure that the adsorption tooth platform 212 and the rubber and plastic parts can contact the trimming machine 414 after being raised. During trimming, the high-speed rotating rubber and plastic parts achieve the trimming effect under the action of the trimming machine 414.

[0064] In one embodiment of this application, such as Figure 6 As shown, the feeding assembly 5 may include a rotating rod 51, a connecting plate 52, and a suction cup 53.

[0065] It should be noted that the rotating rod 51 described in the above embodiment is driven by a geared motor (not shown in the figure), and the connecting plate 52 and the suction cup 53 are connected by an electric push rod (not shown in the figure).

[0066] It should be noted that the suction cup 53 described in the above embodiment is connected to a vacuum pump (not shown in the figure).

[0067] The rotating rod 51 is rotatably mounted on the worktable 1, the suction cup 53 is mounted on the rotating rod 51 through the connecting plate 52, and the unloading assembly 5 is correspondingly set with the loading mechanism 3.

[0068] Specifically, after the rubber and plastic parts on one of the sets of adsorption toothed platforms 212 are trimmed, the electric push rod drives the suction cup 53 to descend and contact the rubber and plastic parts. At this time, because the adsorption toothed platform 212 rotates away from the adsorption assembly 24, the rubber and plastic parts on the adsorption toothed platform 212 lose their adsorption force. Therefore, the suction cup 53 can complete the adsorption of the trimmed rubber and plastic parts. Then, the rotating rod 51 drives the electric push rod and the suction cup 53 to rotate through the connecting plate 52 under the drive of the reduction motor, thereby completing the unloading process of the rubber and plastic parts.

[0069] Specifically, the rubber and plastic parts trimming device provided in this application can be used for trimming rubber and plastic oil seals. In actual operation, relevant personnel pre-place stacked rubber and plastic parts into the material cylinder 33 of the feeding mechanism 3. The support rod at the bottom of the material cylinder 33 supports the entire stack of rubber and plastic parts. When the drive component 23 of the switching mechanism 2 is started, it drives the rotating plate 211 of the placement component 21 to rotate and switch positions. On the other hand, the servo motor 341 of the linkage component 34 drives the rotating ring 342 and the linkage rod 343 to rotate synchronously. The linkage rod 343 drives the lead screw 351 of the feeding component 35 to rotate, driving the slide table 352 to move up and down along the mounting frame 31. During the upward movement of the slide table 352, the flip gear 354 meshes with the toothed plate 32 and rotates, driving the fixed frame 353 to flip through the universal joint, so that the adsorption end of the adsorption component 355 faces the material cylinder 33. After the platform 352 rises to the designated position, the adsorption element 355, which is connected to the external vacuum pump, adsorbs the rubber and plastic parts at the bottom of the material cylinder 33. Utilizing the plasticity of the rubber and plastic parts, the edges of the rubber and plastic parts deform to break free from the constraints of the material cylinder 33 support rod, thus completing the material loading. Subsequently, the lead screw 351 rotates in the reverse direction, driving the slide 352 to descend. The reversing gear 354 meshes with the toothed plate 32 again and reverses, so that the adsorption end of the adsorption element 355 faces downward and aligns with the empty adsorption toothed platform 212 that has been rotated to the loading position. The adsorption element 355 disconnects the negative pressure and places the rubber and plastic parts on the adsorption toothed platform 212, completing the automatic loading.

[0070] Subsequently, the drive motor 231 of the drive assembly 23 drives the transmission gear rod 233 to rotate via the transmission rod 232, thereby causing the rotating plate 211 to rotate a quarter turn around the support plate 22, transferring the adsorption toothed table 212 carrying the rubber and plastic parts to the area below the trimming mechanism 4. Then, the cylinder 241 of the adsorption assembly 24 is activated, pushing the suction box 242 and the adsorption tube 243 upward. The suction box 242 first abuts against the top plate 213 and lifts it upward, causing the adsorption toothed table 212 to lift the rubber and plastic parts to the trimming station. The limiting rod on the suction box 242 is inserted into the insertion hole of the top plate 213 to restrict the circumferential rotation of the top plate 213. At the same time, the external vacuum pump is connected to the adsorption hole of the adsorption toothed table 212 through the suction box 242 and the adsorption tube 243, generating negative pressure to firmly fix the rubber and plastic parts on the adsorption toothed table 212, preventing slippage and displacement during the trimming process.

[0071] During processing, the height and angle of the trimming machine 414 of the trimming assembly 41 are adjusted in advance according to the size and specifications of the rubber and plastic parts to be processed. The horizontal position of the slide plate 413 and the trimming machine 414 is adjusted by the stroke screw 412 to ensure that the processing end of the trimming machine 414 is in close contact with the edge of the lifted rubber and plastic parts. Then, the drive motor 421 of the transmission assembly 42 is started, driving the meshing gear 422 to rotate. The adsorption gear table 212, which meshes with the meshing gear 422, carries the rubber and plastic parts to rotate at high speed. The trimming machine 414 continuously trims the circumferential edge of the rotating rubber and plastic parts to remove excess burrs. During the trimming process, the rubber and plastic parts are always in a negative pressure adsorption and fixed state, without shaking or displacement, and the trimming accuracy is stable.

[0072] After trimming, cylinder 241 drives the vacuum box 242 and adsorption tube 243 to descend and reset. The top plate 213 drives the adsorption tooth platform 212 back onto the rotating plate 211, and the negative pressure adsorption force disappears. The drive assembly 23 drives the rotating plate 211 to rotate a quarter turn again, transferring the trimmed rubber and plastic parts to the unloading station. The electric push rod of the unloading assembly 5 drives the suction cup 53 to descend and contact the rubber and plastic parts. The vacuum pump generates negative pressure through the suction cup 53 to adsorb the finished rubber and plastic parts. Then, the reduction motor drives the rotating rod 51 to rotate, and the suction cup 53 is transferred to the top of the conveyor belt through the connecting plate 52, and the negative pressure is disconnected. The rubber and plastic parts fall onto the conveyor belt and are transported to the next process.

[0073] Throughout the entire operation, the drive component 23 simultaneously drives the switching action and the feeding action. The rhythm of each quarter turn of the rotating plate 211 is perfectly matched with the rhythm of one up-and-down reciprocating operation of the feeding component 35, realizing continuous parallel operation of the feeding, trimming and unloading processes without waiting intervals, greatly improving the trimming efficiency, reducing manual intervention throughout the process, and effectively reducing the labor burden of operators.

[0074] In summary, the rubber and plastic parts production trimming device of this application embodiment can automatically complete the loading and unloading of rubber and plastic parts during the trimming process and simultaneously clean up trimming waste, thereby reducing the labor burden of workers and effectively improving trimming efficiency.
