Description

Technical Field

[0001] This invention belongs to the field of resin button production technology, specifically relating to a bubble-free production device and method for unsaturated polyester resin buttons. Background Technology

[0002] Unsaturated polyester resin buttons are made from unsaturated polyester resin as the main raw material, with the addition of appropriate additives. They are gelled and cured into pearlescent or non-pearlescent sheets or rods in specific equipment and molds, and then mechanically processed. Unsaturated polyester resin buttons are an emerging international garment accessory. They are resistant to acids and alkalis and do not deform after high-temperature washing and ironing. In addition, unsaturated polyester resin buttons have rich color variations, strong simulation, and excellent physical and chemical properties, and have become the leading button product for clothing.

[0003] During the production and processing of unsaturated polyester resin buttons, various additives such as colorants and accelerators are added. Stirring is required to ensure uniform mixing. However, this stirring action results in numerous air bubbles in the unsaturated polyester resin mixture, which easily accumulates on the surface. To ensure that the gelled and cured unsaturated polyester resin sheets or rods contain little or no air bubbles, existing technologies typically involve adding defoamers to the unsaturated polyester resin mixture. However, when a significant amount of foam accumulates on the surface, relying solely on defoamers to eliminate bubbles is time-consuming and inefficient, impacting the efficiency of continuous production. Therefore, inventing a bubble-free production device and method for unsaturated polyester resin buttons is an urgent problem to be solved. Summary of the Invention

[0026] A method for producing bubble-free unsaturated polyester resin buttons using a bubble-free unsaturated polyester resin button production device, the specific steps of which are as follows:

[0027] Step 1: The moving component drives the foam pusher to move along the inside of the pool to push the foam on the surface of the unsaturated polyester resin mixture towards the collection frame. The collection frame receives the foam pushed by the foam pusher. The foam pusher and the collection frame spray defoamer into the pool.

[0028] Step 2: When the foam pusher moves to contact the pushing component, the foam pusher drives the pushing component to move, causing the collection box to move upward and align with the receiving box, and causing the pusher plate 2 to extend into the collection box.

[0029] Step 3: Move push plate 2 by moving component 2 to push the foam inside the collection box out of the collection box and into the receiving box;

[0031] The beneficial effects of this invention are as follows:

[0032] 1) This invention uses a moving component to move a foam pusher along the inside of the pool to push the foam on the surface of the unsaturated polyester resin mixture towards the collection frame. Both the foam pusher and the collection frame can spray defoamer into the pool. The pushing component operates under the pushing action of the foam pusher to move the collection frame containing the foam upwards to align with the receiving frame. The moving component then moves a pusher plate to push the foam out of the collection frame and onto the receiving frame. The moving component then moves the foam pusher back to the initial position. This cycle repeats. With the combined action of foam capture and defoamer spraying, the bubbles in the unsaturated polyester resin mixture are quickly eliminated.

[0033] 2) In this invention, the foam pusher can not only push the foam on the surface of the unsaturated polyester resin mixture to move, but also serve as a power source to drive the pusher component to move, thereby driving the moving component two to move upward. They cooperate with each other and are easy to use.

[0034] 3) The present invention can adjust the height of the pushing component relative to the material pool by means of the first telescopic component, so as to adjust the height of the collecting frame, the pushing component, the second push plate, the second moving component and the receiving frame. The height of the foam pushing component relative to the material pool can be adjusted by means of the second telescopic component, so as to adapt to different liquid level heights and foam thicknesses of the unsaturated polyester resin mixture inside the material pool.

[0049] Collection frame 5, the collection frame 5 is used to receive foam pushed by foam pusher 3;

[0050] The pushing component 6, under the pushing of the foam pushing component 3, drives the collecting frame 5 to move upward;

[0051] Push plate 2 7 is located above collection frame 5. After collection frame 5 is moved upward, push plate 2 7 is located inside collection frame 5.

[0052] Movable component 2 8, which is used to drive push plate 2 7 to move so as to push the foam collected in collection frame 5 out of the collection frame 5.

[0053] The receiving frame 9 is used to receive the foam pushed out of the collection frame 5 by the pusher plate 2 7.

[0054] Preferably, the foam pusher 3 includes a pusher plate 31, a spraying chamber 33 opened inside the pusher plate 31, a plurality of spraying pipes 34 arranged inside the spraying chamber 33 for conveying defoamer, and a plurality of liquid outlets 35 opened at the bottom of the spraying chamber 33. The defoamer is sprayed out through the foam pusher 3, and the liquid outlets 35 are designed to facilitate the leakage of defoamer.

[0055] Both sides of the push plate 31 are downward sloped and the bottom is horizontal. Two side plates 32 are symmetrically provided on the side of the push plate 31 near the collection frame 5 to form a collection cavity with the push plate 31. During the movement of the push plate 31, the foam can be collected through the collection cavity, thereby pushing the foam towards the collection frame 5.

[0056] At least two mesh plates 36 are provided on both sides of the push plate 31, and several puncturing rollers 37 are provided between two adjacent mesh plates 36. The foam pusher 3 is used to puncture the air bubbles in the unsaturated polyester resin mixture.

[0057] In this embodiment, the moving component 4 includes two symmetrically arranged lead screws 41, a nut seat 42 connected to the lead screws 41 via a ball nut pair, and a driving component 43 that drives the two lead screws 41 to rotate. The lead screws 41 are rotatably connected to the support frame 2.

[0058] The drive component 43 includes a servo motor connected to one of the lead screws 41, two synchronous pulleys respectively sleeved on the lead screws 41, and a synchronous belt located between the two synchronous pulleys. The servo motor, the synchronous pulleys, and the synchronous belt drive the two lead screws 41 to rotate synchronously, and the nut seat 42 moves back and forth along the lead screws 41, thereby driving the foam pusher 3 to move back and forth.

[0059] Preferably, the collection frame 5 includes a frame 51, a fixing plate 52 disposed on the upper part of the inside of the frame 51, a mesh plate 53 disposed on the lower part of the inside of the frame 51, a guide plate 55 disposed between the mesh plate 53 and the bottom of the inside of the frame 51, a plurality of spray pipes 54 disposed between the mesh plate 53 and the guide plate 55, a plurality of liquid outlets 56 opened on the bottom of the inside of the frame 51, and a conveying pipe connected to the collection frame 5 and extending into the unsaturated polyester resin mixture. The frame 51 receives the foam pushed by the foam pusher 3, and the mesh plate 53 is used to allow the unsaturated polyester resin mixture to leak out. The leaked unsaturated polyester resin mixture falls to the top of the guide plate 55 and is guided to the liquid outlets 56 for delivery.

[0060] The frame 51 has openings on the top and on the side near the foam pusher 3. Several discharge channels 57 are provided on the two side walls of the frame 51 adjacent to the side near the foam pusher 3. Under the push of the pusher plate 7, the foam inside the frame 51 leaks out through the discharge channels 57.

[0061] Preferably, the pushing component 6 includes two sets of symmetrically arranged push rod assemblies, a support plate 63 connected to the support frame 2, a plurality of springs 65 disposed between the fixed plate 52 and the support plate 63, and a plurality of guide rods 64 disposed on the fixed plate 52 and respectively located inside each spring 65 for limiting and guiding the spring 65. The top of the guide rod 64 passes through the support plate 63 and is provided with a baffle 66.

[0062] The push rod assembly includes a hinge seat 61 that is slidably connected to the material pool 1, and a push rod 62 that is rotatably connected to the hinge seat 61 and the side wall of the frame 51.

[0063] At least one groove is provided on the inner wall of the material pool 1 for the hinge seat 61 to slide horizontally.

[0064] The hinge seat 61 moves horizontally along the slide groove under the push of the push plate 31 and the mesh plate 36, and compresses the spring 65, so that the collecting frame 5 moves up and aligns with the receiving frame 9. When the foam pusher 3 moves away from the collecting frame 5, the collecting frame 5 can move down and return to the initial position under the elastic force of the spring 65.

[0065] Preferably, the number of push plates 7 is at least one, and the moving component 8 includes a fixed frame 81 disposed at the bottom of the support plate 63, a lead screw 82 rotatably connected to the fixed frame 81, a nut seat 83 connected to the lead screw 82 through a ball bearing pair, and a driving component 84 for driving the lead screw 82 to rotate. The push plates 7 and the nut seats 83 correspond one-to-one and are connected to each other.

[0066] In this embodiment, when there is only one lead screw 82, the second driving component 84 includes a second servo motor connected to the second lead screw 82;

[0067] When there are two or more lead screws 82, each lead screw 82 includes a servo motor 2 connected to one of the driving components 84, several synchronous pulleys 2 respectively sleeved on each lead screw 82, and several synchronous belts 2 for driving the synchronous pulleys 2 to rotate synchronously.

[0068] The driving component 2 84 drives the lead screw 2 82 to rotate, so that the nut seat 2 83 drives the push plate 2 7 to move along the lead screw 2 82. The push plate 2 7 pushes the foam inside the frame 51 to be output from the frame 51 and fall into the receiving frame 9.

[0069] A method for producing bubble-free unsaturated polyester resin buttons using a bubble-free unsaturated polyester resin button production device, the specific steps of which are as follows:

[0070] Step 1: The foam pusher 3 is moved along the inside of the material tank 1 by the moving component 4 to push the foam on the surface of the unsaturated polyester resin mixture in the material tank 1 toward the collection frame 5. The collection frame 5 receives the foam pushed by the foam pusher 3. The foam pusher 3 and the collection frame 5 spray defoamer into the material tank 1.

[0071] Step 2: When the foam pusher 3 moves to contact the pusher component 6, the foam pusher 3 drives the pusher component 6 to move the collection frame 5 upward to align with the receiving frame 9, and causes the pusher plate 2 7 to extend into the collection frame 5.

[0072] Step 3: Move the pusher plate 7 by moving component 2 8 to push the foam inside the collection box 5 out of the collection box 5 and let it fall into the receiving box 9;

[0073] Step 4: Repeat steps 1 to 3 until the bubbles and foam in and on the surface of the unsaturated polyester resin mixture are removed.

[0074] Furthermore, the material tank 1 is equipped with a stirring structure (not shown in the figure) for mixing saturated polyester resin mixture and defoamer. The stirring structure is a conventional technical solution and will not be described in detail here.

[0075] It should be noted that, in this embodiment, the addition of defoamer into the material tank 1 can also be done in accordance with conventional techniques, by adding it together with various additives such as colorants and accelerators, and then mixing it evenly in the unsaturated polyester resin mixture through the stirring structure. That is, the defoamer sprayed by the foam pusher 3 and the collection frame 5 and the defoamer added by conventional techniques are used in combination.

[0076] Example 2

[0077] like Figure 1-7 As shown, a bubble-free production device for unsaturated polyester resin buttons differs from Embodiment 1 in that, in this embodiment, the support plate 63 and the support frame 2 are slidably connected vertically, and a first telescopic member 10 is provided between the support frame 2 and the support plate 63.

[0078] A second telescopic component 11 is provided between the foam-propelling component 3 and the moving component 4.

[0079] In this embodiment, the receiving frame 9 is disposed on the support plate 63.

[0080] The height of the pushing component 6 relative to the material pool 1 can be adjusted by the first telescopic component 10, so as to adjust the height of the collection frame 5, the pushing component 6, the second push plate 7, the second moving component 8, and the receiving frame 9.

[0081] The height of the foam pusher 3 relative to the material tank 1 can be adjusted by the second telescopic member 11 to adapt to different liquid level heights and foam thicknesses of the unsaturated polyester resin mixture inside the material tank 1.

[0082] It should be noted that in this embodiment, the height of the hinge seat 61 is adjusted by snapping it into different height slides. The installation and disassembly of the hinge seat 61 into different slides are conventional technical means, and will not be described in detail here.

[0083] Furthermore, to ensure that the foam inside the collection frame 5 is discharged from the discharge channel 57 as much as possible, a roller shutter structure is installed on the side of the frame 51 near the foam pusher 3. The roller shutter structure consists of a drive motor, a winding roller, and a winding door panel on the winding roller. The winding door panel is slidably connected to the frame 51. After the frame 51 moves upward, the roller shutter structure lowers to form a shield. After the frame 51 moves downward, the roller shutter structure retracts to facilitate foam collection.

[0084] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
