Description

Technical Field

[0001] This utility model relates to the field of laminate production technology, specifically a cleaning and blowing device for thermoplastic molded laminates. Background Technology

[0002] Before thermoplasticizing the laminate, the mold is usually cleaned to improve the surface smoothness of the laminate, thereby preventing dust or impurities from adhering to the laminate.

[0003] Currently, most thermoplastic molds are cleaned using airflow blowing. However, when removing dust, the airflow direction is usually fixed. After cleaning, directional blowing can create dead corners on the far left or far right of the mold, leading to improper mold cleaning. In subsequent thermoplastic processes, these residual dust or impurities will affect the final product quality, resulting in a decline in production quality. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning and blowing device for thermoplastic molded laminates to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cleaning and blowing device for thermoplastic molded laminates includes: a thermoplastic device, on which a lower mold is disposed;

[0007] The thermoplastic device is also equipped with a reciprocating assembly, which includes a movable component slidably disposed on the thermoplastic device. A mounting plate is elastically disposed on the movable component. A blowing assembly and a stabilizing assembly are disposed on the mounting plate. The blowing assembly includes a blowing pipe rotatably mounted on the mounting plate. The blowing pipe is connected to the stabilizing assembly. When the reciprocating assembly drives the movable component to slide along the length direction of the thermoplastic device, the stabilizing assembly enables the blowing pipe to blow and clean the lower mold at the same angle. When the movable component moves to the end of its stroke, the stabilizing assembly cooperates with a triggering assembly disposed on the thermoplastic device to change the blowing direction of the blowing pipe, so that the blowing pipe can thoroughly clean the lower mold.

[0008] The cleaning and blowing device for the thermoplastic molded laminate as described above: two sets of moving parts are arranged along the width direction of the thermoplastic device. Each set of moving parts includes a moving plate that is slidably disposed on the thermoplastic device. The moving plate has a moving groove on the side facing the lower mold. A slider is provided on the moving plate. The slider is slidably disposed in the groove opened on the thermoplastic device.

[0009] The cleaning and blowing device for the thermoplastic molded laminate as described above: the reciprocating assembly further includes a connecting rod rotatably mounted on the lower mold. Two sets of the connecting rod are symmetrically arranged along the length direction of the lower mold. Both ends of the two sets of connecting rods are coaxially provided with pulleys, and a belt is provided between the two sets of pulleys on the same side. A protruding post is provided on the side of the belt away from the lower mold, and the protruding post is slidably disposed in the moving groove.

[0010] The cleaning and blowing device for the thermoplastic molded laminate as described above: the mounting plate is connected to the moving plate through an elastic structure. The elastic structure includes two sets of slide rods respectively disposed on the moving plate. Each set of slide rods is fitted with a second spring. One end of the second spring abuts against the moving plate, and the other end abuts against the mounting plate.

[0011] The cleaning and blowing device for the thermoplastic molded laminate as described above: the stabilizing component includes a rotating rod rotatably mounted on two sets of mounting plates, the two ends of the rotating rod being coaxially and fixedly connected to deflection plates rotatably mounted on the two sets of mounting plates, and the two sets of deflection plates being elastically connected to stabilizing members disposed on the mounting plates.

[0012] The cleaning and blowing device for the thermoplastic molded laminate as described above: the stabilizing component includes a stabilizing plate disposed on the mounting plate, an upper baffle and a lower baffle are respectively disposed on the upper and lower sides of the stabilizing plate, and a first connecting post is disposed on the side of the stabilizing plate away from the mounting plate, the first connecting post being fixedly connected to a second connecting post disposed on the deflection plate by a third spring.

[0013] The cleaning and blowing device for the thermoplastic molded laminate as described above: the triggering component includes a lifting sleeve, and two sets of lifting sleeves are provided. The two sets of lifting sleeves are slidably connected to a support rod provided on the thermoplastic device. A first spring is sleeved on the support rod. One end of the first spring abuts against the thermoplastic device, and the other end abuts against the lifting sleeve. Each set of lifting sleeves is provided with a trigger rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] By setting up a reciprocating component, the reciprocating component drives the blowing pipe to slide back and forth, thereby reciprocating the blowing of the lower mold and improving the cleaning effect.

[0016] Meanwhile, by setting up stabilizing components, the blowpipe can spray air at a fixed angle during the movement of the blowpipe, ensuring that the stabilizing effect on the lower mold is avoided and improving the blowing quality.

[0017] Furthermore, when the purge pipe moves to the end of its stroke, the triggering component can drive the purge pipe to deflect in direction, thereby eliminating the residual dead corners on the left or right side during traditional unidirectional cleaning, and thus improving the final product quality.

[0018] During the subsequent pressing down of the upper pressure plate, the setting of the first and second springs can avoid interference between the purge pipe and the trigger rod and the upper pressure plate during the hot pressing process. Attached Figure Description

Detailed Implementation

[0028] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0029] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0030] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0031] Please see Figures 1-8 In this embodiment of the present invention, a cleaning and blowing device for thermoplastic molded laminate includes:

[0032] Thermoplastic device 1, wherein a lower mold 2 is provided on thermoplastic device 1;

[0033] Specifically, please refer to Figure 1 The thermoplastic device 1 is also provided with four sets of support rods 4. The four sets of support rods 4 are evenly distributed on the thermoplastic device 1, and an upper pressure plate 101 is slidably arranged on the four sets of support rods 4. The upper pressure plate 101 is connected to the lifting structure on the thermoplastic device 1. Under the drive of the lifting structure, the upper pressure plate 101 can press down on the lower mold 2 to complete the thermoplastic operation of the laminate.

[0034] Specifically, the lower mold 2 has a mold groove. In order to improve the quality of the finished product during the thermoplastic process of the laminate, the dust and other impurities adhering to the mold groove must be removed first so that the surface of the laminate formed later is smooth.

[0035] Furthermore, the thermoplastic device 1 is also provided with a reciprocating assembly, which includes a movable component slidably disposed on the thermoplastic device 1. A mounting plate 11 is elastically disposed on the movable component. A blowing assembly and a stabilizing assembly are disposed on the mounting plate 11. The blowing assembly includes a blowing pipe 3 rotatably mounted on the mounting plate 11. The blowing pipe 3 is connected to the stabilizing assembly. When the reciprocating assembly drives the movable component to slide along the length direction of the thermoplastic device 1, the stabilizing assembly enables the blowing pipe 3 to blow and clean the lower mold 2 at the same angle. When the movable component moves to the end of its stroke, the stabilizing assembly cooperates with a triggering assembly disposed on the thermoplastic device 1 to change the blowing direction of the blowing pipe 3 so that the blowing pipe 3 can thoroughly clean the lower mold 2.

[0036] Two sets of movable components are arranged along the width direction of the thermoplastic device 1. Each set of movable components includes a movable plate 7 that is slidably disposed on the thermoplastic device 1. A movable groove 701 is opened on the side of the movable plate 7 facing the lower mold 2. A slider 702 is provided on the movable plate 7. The slider 702 is slidably disposed in the groove 102 opened on the thermoplastic device 1.

[0037] For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 With the cooperation of the slide groove 102 and the slider 702, the moving plate 7 can only slide along the length direction of the thermoplastic device 1.

[0038] The reciprocating assembly also includes a connecting rod 6 rotatably mounted on the lower mold 2. Two sets of the connecting rod 6 are symmetrically arranged along the length of the lower mold 2. Both ends of the two sets of connecting rods 6 are coaxially provided with pulleys 8, and a belt 5 is provided between the two sets of pulleys 8 on the same side. A protruding post 501 is provided on the side of the belt 5 away from the lower mold 2. The protruding post 501 is slidably disposed in the moving groove 701.

[0039] Specifically, please refer to Figures 1-4 One of the aforementioned connecting rods 6 is connected to a motor mounted on the thermoplastic device 1. Initially, the moving plate 7 is located at the beginning of the stroke of the slide groove 102, as shown below. Figure 1 As shown.

[0040] Before the thermoplasticizing of the laminate, the motor is started first. Then, the motor drives the two sets of connecting rods 6 to rotate synchronously. During this process, the protruding column 501 and the moving groove 701 cooperate to drive the moving plate 7 to slide back and forth along the slide groove 102 until the moving plate 7 drives the blowing pipe 3 to move back and forth once. Then the motor stops. During this process, the blowing pipe 3 can cooperate with the stabilizing component and the triggering component to complete the cleaning operation of the upper mold groove of the lower mold 2. Then the lifting structure drives the upper pressure plate 101 to move towards the lower mold 2, thereby completing the thermoplasticizing of the laminate.

[0041] It should be further explained that the mounting plate 11 is connected to the movable plate 7 through an elastic structure. The elastic structure includes two sets of slide rods 12 respectively disposed on the movable plate 7. Each set of slide rods 12 is fitted with a second spring 13. One end of the second spring 13 abuts against the movable plate 7, and the other end abuts against the mounting plate 11.

[0042] Specifically, the second spring 13 is always in a compressed state, so that the blow pipe 3 is higher than the lower mold 2, so that the blow pipe 3 can blow the mold groove. When the blow pipe 3 completes the blowing process and returns to the initial position, the pressing upper platen 101 will contact the blow pipe 3 and push the blow pipe 3 down along the axial direction of the slide bar 12, so that the blow pipe 3 can make way and avoid the blow pipe 3 interfering with the thermoplastic operation of the upper platen 101.

[0043] Please see Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8 The stabilizing component includes a rotating rod 14 rotatably mounted on two sets of mounting plates 11. The two ends of the rotating rod 14 are coaxially fixedly connected to deflection plates 17 rotatably mounted on the two sets of mounting plates 11, and the two sets of deflection plates 17 are elastically connected to the stabilizing elements provided on the mounting plates 11.

[0044] The stabilizer includes a stabilizer plate 16 disposed on the mounting plate 11. An upper baffle 1602 and a lower baffle 1603 are respectively disposed on the upper and lower sides of the stabilizer plate 16. A first connecting post 1601 is disposed on the side of the stabilizer plate 16 away from the mounting plate 11. The first connecting post 1601 is fixedly connected to a second connecting post 1701 disposed on the deflection plate 17 by a third spring 18.

[0045] Specifically, the two sets of stabilizers mentioned above, such as Figure 7As shown in the state setting, the rotating rod 14 is connected to the blowing pipe 3 via the linkage belt 15, and the third spring 18 is in a stretched state. During the movement of the moving plate 7, the third spring 18 can maintain the angle between the deflection plate 17 and the stabilizing plate 16, so that during the movement of the blowing pipe 3, the nozzle 301 can maintain the same angle to blow and clean the mold, thereby improving the blowing quality.

[0046] In the initial state, with Figure 7 The description focuses on the right-side stabilizer. The deflector plate 17 is attached to the lower baffle 1603 (another set is attached to the upper baffle 1602). At this time, the purge pipe 3 deflects to the right (see reference). Figure 1 The moving plate 7 is located on the far left of the thermoplastic device 1. When the reciprocating component drives the moving plate 7 to move to the right, the blow pipe 3 enters the working state and sprays a stable airflow outward through the nozzle 301. As the moving plate 7 moves, the blow pipe 3 can clean the dust and impurities in the mold groove to the right until the moving plate 7 moves to the end of the travel of the slide 102. At this time, the blow pipe 3 completes the cleaning of the far right of the mold groove. At this time, due to the bias setting of the nozzle 301 of the blow pipe 3, there are still residual dust and impurities on the far left of the mold groove.

[0047] In this invention, when the moving plate 7 moves to the end of its stroke, the triggering component triggers the stabilizing component. Subsequently, the triggering component drives the blowing pipe 3 to rotate, causing its nozzle 301 to deflect to the left. Then, as the moving plate 7 moves in the opposite direction under the drive component, the nozzle 301 deflected to the left can blow on the left side of the mold groove, thereby removing the impurities and dust that were previously left on the far left side of the mold groove, so as to keep the mold groove clean and improve the quality of the thermoplastic product.

[0048] In detail, the triggering component includes a lifting sleeve 9, and two sets of lifting sleeves 9 are provided. The two sets of lifting sleeves 9 are slidably connected to the support rod 4 provided on the thermoplastic device 1. A first spring 10 is sleeved on the support rod 4. One end of the first spring 10 abuts against the thermoplastic device 1 and the other end abuts against the lifting sleeve 9. Each set of lifting sleeves 9 is provided with a trigger rod 19.

[0049] Please see Figure 1 The two sets of triggering components are set on two sets of support rods 4 located diagonally, and the first spring 10 is always in a compressed state, so that the lifting sleeve 9 tends to move closer to the upper pressure plate 101.

[0050] In conjunction with the above, during the process of the moving plate 7 moving to the rightmost end of the stroke of the slide 102, the trigger rod 19 will first contact the deflection plate 17, and then push the deflection plate 17 to rotate clockwise (in particular, to ensure that the above process occurs normally, the elastic potential energy stored in the first spring 10 is greater than that in the third spring 18). During this process, the tension of the third spring 18 increases, and at the same time, the rotating rod 14 drives the blowpipe 3 to deflect slowly clockwise. From the vertical plane, the blowpipe 3 is no longer above the lower mold 2. Until the moving plate 7 moves to the end of the stroke, the deflection plate 17 crosses the plane where the stabilizing plate 16 is located. Immediately afterwards, the third spring 18 quickly retracts, driving the deflection plate 17 to flip quickly until the deflection plate 17 is in contact with the upper baffle 1602. At this time, the nozzle 301 is kept in the direction of deflection to the left under the action of the third spring 18, so that during the subsequent reverse movement of the moving plate 7, the blowpipe 3 can blow away the impurities remaining on the leftmost side of the mold groove.

[0051] After cleaning is completed, as the upper pressure plate 101 descends, it can simultaneously drive the lifting sleeve 9 to descend, thus enabling the thermoplastic process to proceed normally.

[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0053] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
