Description

Technical Field

[0001] The present application relates to the technical field of plastic parts processing, and in particular to a spraying support tooling for plastic products. Background Art

[0002] Plastic is a high molecular compound made from monomers through addition polymerization or condensation polymerization. It has a medium deformation resistance, between fiber and rubber. It is composed of synthetic resin and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants.

[0003] The main component of plastic is resin. Resin refers to a high molecular compound that has not been mixed with various additives. The term resin was originally derived from the lipids secreted by animals and plants, such as rosin and shellac. Resin accounts for about 40% to 100% of the total weight of plastic. The basic properties of plastic are mainly determined by the nature of the resin, but additives also play an important role. Some plastics are basically composed of synthetic resins, with no or little additives, such as plexiglass.

[0004] Plastic products often need to be sprayed during processing, which not only makes the plastic parts beautiful but also effectively improves the wear resistance of the plastic parts. When spraying plastic products, spray support tooling is generally used to fix the plastic products. However, the existing spray support tooling is difficult to apply to plastic products of different specifications, resulting in a small scope of application of the spray support tooling. Utility Model Content

[0005] Based on this, it is necessary to provide a spray support tool for plastic products to address the problem that the existing spray support tool is difficult to apply to plastic products of different specifications, resulting in a small scope of application of the spray support tool.

[0006] The present application provides a spraying support tool for a plastic product, comprising:

[0007] A spraying platform, wherein the spraying platform is provided with a processing chamber;

[0008] A spraying assembly, wherein the spraying assembly is arranged on the top surface of the spraying platform, and the spraying assembly comprises a spraying chamber, a hydraulic cylinder, a clamping main arm, a first motor and a clamping auxiliary arm, wherein the spraying chamber is fixedly connected to the top surface of the spraying platform, the hydraulic cylinder is arranged in the spraying chamber, one end of the clamping main arm is fixedly connected to the driving rod of the hydraulic cylinder, the first motor is fixedly connected to the other end of the clamping main arm, and the clamping auxiliary arm is fixedly connected to the rotating shaft of the first motor;

[0009] A pushing component is arranged on the spraying platform, and the pushing component includes a driving motor, a fixing support and a first sensor. The bottom surface of the driving motor is fixedly connected to the bottom surface of the processing chamber, the fixing support is fixedly connected to the driving end of the driving motor, and the first sensor is arranged at the entrance of the spraying chamber.

[0010] The present application relates to a spraying support tooling for plastic products. After the plastic product enters the spraying room, the first sensor is triggered, so that the driving motor pushes the fixing support to move upward, so as to fix the plastic product in the spraying room and complete the spraying of the first side. After the spraying of the first side is completed, the clamping main arm cooperates with the clamping auxiliary arm to clamp the plastic product from two directions. The first motor is started to drive the clamping auxiliary arm to rotate, thereby driving the plastic product to rotate, so as to complete the spraying of the second side of the plastic product. Since the length of the clamping auxiliary arm can be adjusted, the clamping auxiliary arm can fix plastic products of different specifications, thereby improving the applicability of the spraying support tooling.

[0024] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0025] The present application provides a spraying support tool for a plastic product.

[0026] like Figure 1 and Figure 2 As shown, in one embodiment of the present application, the spraying support tooling of the plastic product includes a spraying platform 100 , a spraying assembly 200 and a pushing assembly 300 .

[0027] The spraying platform 100 is provided with a processing chamber 101. The spraying assembly 200 is arranged on the top surface of the spraying platform 100, and the spraying assembly includes a spraying chamber 201, a hydraulic cylinder 202, a clamping main arm 203, a first motor 204 and a clamping auxiliary arm 205. The spraying chamber 201 is fixedly connected to the top surface of the spraying platform 100, the hydraulic cylinder 202 is arranged in the spraying chamber 201, one end of the clamping main arm 203 is fixedly connected to the driving rod of the hydraulic cylinder 202, the first motor 204 is fixedly connected to the other end of the clamping main arm 203, and the clamping auxiliary arm 205 is fixedly connected to the rotating shaft of the first motor 204. The pushing component 300 is arranged on the spraying platform 100, and the pushing component 300 includes a driving motor 301, a fixed support 302 and a first sensor 303. The bottom surface of the driving motor 301 is fixedly connected to the bottom surface of the processing chamber 101, the fixed support 302 is fixedly connected to the driving end of the driving motor 301, and the first sensor 303 is arranged at the entrance of the spraying chamber 201.

[0028] In this embodiment, after the plastic product enters the spraying chamber 201, the first sensor 303 is triggered, so that the driving motor 301 pushes the fixing support 302 to move upward, so as to fix the plastic product in the spraying chamber 201 and complete the spraying of the first side. After the spraying of the first side is completed, the clamping main arm 203 cooperates with the clamping auxiliary arm 205 to clamp the plastic product from two directions, and the first motor 204 is started to drive the clamping auxiliary arm 205 to rotate, thereby driving the plastic product to rotate, so as to complete the spraying of the second side of the plastic product. Since the length of the clamping auxiliary arm 205 can be adjusted, the clamping auxiliary arm 205 can fix plastic products of different specifications, thereby improving the applicability of the spraying support tooling.

[0029] like Figure 3 As shown, in one embodiment of the present application, the clamping auxiliary arm 205 includes a clamping plate 206, a connecting piece 207 and a plurality of telescopic plates 208, the clamping plate 206 is fixedly connected to one end of the clamping main arm 203, the telescopic plate 208 is slidably connected to the clamping plate 206, and the plurality of telescopic plates 208 are symmetrically arranged about the horizontal midline of the clamping plate 206.

[0030] Specifically, a sliding groove 209 is also provided on the inner wall of the clamping plate 206 , so that the telescopic plate 208 close to the clamping plate 206 can be retracted into the clamping plate 206 .

[0031] In this embodiment, the connection between the clamping plate 206 and the telescopic plate 208, and the telescopic plate 208 and the telescopic plate 208 are realized by the connecting piece 207, so that the telescopic plate 208 can be freely extended and retracted, thereby adjusting the length of the clamping auxiliary arm 205, so that the clamping auxiliary arm 205 can be suitable for plastic products of different specifications.

[0032] When the diameter of the plastic product is relatively large, the telescopic plate 208 can be unfolded to increase the length of the auxiliary clamping arm 205 , so that the plastic product is clamped between the left and right auxiliary clamping arms 205 .

[0033] like Figure 3 As shown, in one embodiment of the present application, the connecting member 207 includes a slide groove 209, a rotating wheel 210 and a fixed tooth 211, the side wall of the telescopic plate 208 is provided with a slide groove 209, the slide groove 209 is provided with a fixed tooth 211, and the rotating wheel 210 is fixedly connected to the rear end of the telescopic plate 208.

[0034] Specifically, the rotating wheel 210 is disposed near the end of the sliding groove 209 .

[0035] In this embodiment, different telescopic plates 208 are connected together via a connector 207, wherein a pulley at the rear end of one telescopic plate 208 is fixedly connected to a slide groove 209 of another telescopic plate 208, thereby fixing the two telescopic plates 208 together.

[0036] The pulley of one telescopic plate 208 can slide along the slide groove 209 of another telescopic plate 208 to adjust the relative positions of the two telescopic plates 208, thereby adjusting the length of the clamping auxiliary arm 205. Since there are multiple fixed teeth 211 in the slide groove 209, the position of the pulley can be fixed, thereby fixing the position of the telescopic plate 208.

[0037] like Figure 4 As shown, in one embodiment of the present application, a plurality of the fixed teeth 211 are provided, and the plurality of the fixed teeth 211 are arranged at equal intervals on the groove wall of the slide groove 209 , and the radius of the fixed teeth 211 is equal to the radius of the rotating wheel 210 .

[0038] Specifically, the greater the number of the fixed teeth 211 , the more accurate the position adjustment of the telescopic plate 208 is.

[0039] Optionally, fixing teeth 211 may be provided on both the top surface and the bottom surface of the slide groove 209 to improve the fixing effect.

[0040] In this embodiment, the position of the pulley is fixed by the fixed teeth 211 , thereby adjusting the position of the telescopic plate 208 .

[0041] like Figure 2 As shown, in one embodiment of the present application, the fixed support 302 includes a support seat 304, a connecting seat 305 and a second motor 306, the support seat 304 is a rectangular parallelepiped with a hollow interior, the bottom surface of the support seat 304 is fixedly connected to the driving end of the driving motor 301, the bottom surface of the second motor 306 is fixedly connected to the bottom surface of the support seat 304, and the connecting seat 305 is fixedly connected to the rotating shaft of the second motor 306.

[0042] In this embodiment, when the plastic product is transported to the processing chamber 101 via the conveyor belt 102, the driving motor 301 pushes the fixed support 302 upward, thereby allowing the plastic product to separate from the conveyor belt 102. Then the second motor 306 works to drive the connecting seat 305 to rotate, thereby causing the plastic product located above the connecting seat 305 to rotate together, thereby making the spraying of the plastic product more uniform.

[0043] Since the spray port 212 is located on the top plate 201c of the spray room 201, only the surface of the plastic product close to the top plate 201c of the spray room 201 can be sprayed, so the spray assembly 200 is needed to assist in turning over the plastic product.

[0044] When the first side is sprayed, the hydraulic cylinder 202 works to adjust the position of the clamping main arm 203 so that the clamping main arm 203 is located in the middle of the plastic product, and then pushes the clamping auxiliary arm 205 so that the plastic product is clamped between the clamping auxiliary arms 205.

[0045] After ensuring that the fixation is stable, the first motor 204 starts to work, driving the clamping auxiliary arm 205 to rotate, thereby driving the plastic product to rotate, so that the surface of the plastic product originally away from the top plate 201c of the spray chamber 201 faces upward, thereby completing the turning over of the plastic product and completing the spraying of the second side of the plastic product.

[0046] like Figure 1 As shown, in one embodiment of the present application, the spray chamber 201 includes a first side plate 201a, a second side plate 201b and a top plate 201c, the top plate 201c is fixedly connected between the first side plate 201a and the second side plate 201b, and the first side plate 201a and the second side plate 201b are arranged in parallel.

[0047] Specifically, the hydraulic cylinder 202 is fixedly connected to the first side plate 201a and the second side plate 201b respectively.

[0048] In this embodiment, the first side plate 201a and the second side plate 201b form a passage, and the conveyor belt 102 passes through the passage formed by the first side plate 201a and the second side plate 201b.

[0049] Along the conveying direction of the conveyor belt 102, one end of the first side panel 201a and the second side panel 201b forms the entrance of the spraying room 201, and the other end of the first side panel 201a and the second side panel 201b forms the exit of the spraying room 201. Plastic products enter the spraying room 201 from the entrance of the spraying room 201 and are discharged through the exit of the spraying room 201 after spraying is completed.

[0050] like Figure 2 As shown, in one embodiment of the present application, two clamping main arms 203 are provided, and the two clamping main arms 203 are respectively fixedly connected to the first side plate 201a and the second side plate 201b.

[0051] In this embodiment, since different plastic products have different specifications, the position of the clamping main arm 203 needs to be adjusted by the hydraulic cylinder 202 so that the clamping auxiliary arm 205 can be located close to the middle of the plastic product, thereby making the clamping auxiliary arm 205 clamp the plastic product more stably.

[0052] The reason for providing at least two clamping main arms 203 is to clamp the plastic product from two directions simultaneously, thereby improving the clamping stability.

[0053] like Figure 2As shown, in one embodiment of the present application, the sensor includes a transmitting end 303a and a receiving end 303b, the transmitting end 303a is fixedly connected to the first side plate 201a of the spraying room 201, and the receiving end 303b is fixedly connected to the second side plate 201b of the spraying room 201, and the transmitting end 303a and the receiving end 303b are symmetrically distributed about the central axis of the top plate 201c of the spraying room 201.

[0054] In this embodiment, when the plastic product reaches the entrance of the spray chamber 201, the plastic product blocks the laser emitted by the transmitting end 303a to the receiving end 303b, and the receiving end 303b does not receive the signal to control the drive motor 301 to work, so that the drive motor 301 pushes the fixed support 302 to move upward, thereby separating the plastic product from the conveyor belt 102.

[0055] After the spraying is completed, the driving motor 301 drives the fixed support 302 to move downward, so that the sprayed plastic products return to the conveyor belt 102 and are discharged through the outlet of the spraying room 201.

[0056] like Figure 5 As shown, in one embodiment of the present application, a conveyor belt 102 is disposed on the surface of the spraying platform 100 , and the spraying chamber 201 is covered on the top of the processing chamber 101 .

[0057] Specifically, the conveyor belt 102 is divided into two parts, one part is located near the entrance of the spraying room 201 , and the other part is located near the exit of the spraying room 201 .

[0058] In this embodiment, the unsprayed plastic products are transported to the spraying room 201 by the conveyor belt 102 , and the sprayed plastic products are transported out of the spraying room 201 .

[0059] like Figure 2 As shown, in one embodiment of the present application, a top plate 201 c of the spraying room 201 is fixedly connected with a spraying port 212 , and a plurality of the spraying ports 212 are arranged on the top plate 201 c of the spraying room 201 at equal intervals.

[0060] Specifically, the spray port 212 is connected to an external dye source.

[0061] Optionally, the first sensor 303 is also connected to the spray port 212, and when the signal of the first sensor 303 is neutral, the spray port 212 can be started.

[0062] In this embodiment, the spraying port 212 completes the spraying of the plastic product, and a plurality of spraying ports 212 can cover the entire processing chamber 101, thereby avoiding the phenomenon of spray leakage.

[0063] Since the second motor 306 drives the plastic product to rotate, and the main clamping arm 203 cooperates with the auxiliary clamping arm 205 to complete the turning over of the plastic product, the spraying of the plastic product is more uniform and there is no dead angle in the spraying.

[0064] The technical features of the above-described embodiments may be arbitrarily combined, and the execution order of the method steps is not limited. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0065] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
