Description

Technical Field

[0001] The present invention relates to the technical field of demolding and trimming treatment of noise reduction filling blocks, and specifically provides a device and method for demolding and trimming treatment of PE molded sealed noise reduction filling blocks. Background Art

[0002] The PE molded sealed noise reduction filling block is a multi-functional sealing and noise reduction material with good sealing performance, noise reduction effect and weather resistance, and is widely used in various mechanical equipment, buildings and transportation vehicles.

[0003] At present, the PE molded sealed noise reduction filling blocks are usually made by cutting the molded plates. This method can ensure that the filling blocks have precise dimensions and shapes to meet the requirements of different application scenarios, and the PE molded plates required for the preparation of the PE molded sealed noise reduction filling blocks are prepared by PE plastic molding.

[0004] During the molding preparation process, a mold release agent is usually applied to the surface of the mold to prevent the material from adhering to the mold. The mold release agent may remain on the surface of the plate, affecting subsequent cutting and use; at the same time, some surface defects such as bubbles, cracks, unevenness, etc. may occur during the molding process, and these defects will affect the flatness and aesthetics of the plate; therefore, the PE molded plates required for the preparation of the PE molded sealed noise reduction filling blocks need to be subjected to surface grinding and trimming treatment after demolding.

[0005] After demolding, the size of the PE molded plate is large. After the PE molded plate is fixed, its middle part is in a suspended state and is easily concave under the action of its own gravity, resulting in inconsistent grinding degrees at the edges and the middle part of the PE molded plate during the grinding process, affecting the trimming quality, and the trimming treatment quality needs to be improved.

[0018] The present invention also provides a demolding and trimming method for a PE molded sealing noise reduction filling block, comprising the following steps: S1, placement and fixation: inserting a PE molded sheet between an end pressing plate and a horizontal section of a support platform, driving the end pressing plate downward by a lifting drive source to fix the PE molded sheet, and during the downward movement of the end pressing plate, a positioning group centers the PE molded sheet along its width direction.

[0019] S2, moving locking: the end pressure plate drives the connecting frame located on the upper side of the PE molded sheet to move downward through the synchronous lifting group, and the connecting frame located on the upper side drives the connecting frame located on the lower side to move toward the PE molded sheet through the synchronous locking group until the grinding discs on the upper and lower sides collide with the PE molded sheet.

[0020] S3, alternating support and polishing: the double-sided trimming mechanism located in the middle supports the middle part of the PE molded sheet through the polishing discs on its upper and lower sides, and another double-sided trimming mechanism is started. The grinder drives the polishing disc to polish the PE molded sheet. At the same time, the longitudinal drive group and the transverse drive group in the double-sided trimming mechanism cooperate to drive the connecting frames on the upper and lower sides to move synchronously, and the polishing discs on the upper and lower sides support each other when polishing the PE molded sheet. When the double-sided trimming mechanism in the polishing work moves to the middle part of the PE molded sheet, it is staggered with the double-sided trimming mechanism that was not working before to polish the middle part of the PE molded sheet together. After that, the double-sided trimming mechanism that completed the polishing work before stops working and supports the middle part of the PE molded sheet again.

A demolding and trimming processing device for a PE molded sealing noise reduction filling block designed by the present invention grinds and trims the PE molded sheet material through alternating cooperation of two double-sided trimming mechanisms, which not only ensures that the middle part of the PE molded sheet material is always stably supported during the grinding and trimming process, but also further supports the PE molded sheet material through the mutual support of the grinding discs on the upper and lower sides. The double supporting effect of the two double-sided trimming mechanisms avoids the problem of inconsistent grinding degrees at the edges and the middle of the PE molded sheet material, which affects the trimming quality of the PE molded sheet material, thereby improving the stability and efficiency of the grinding and trimming of the PE molded sheet material.

[0023] 2. When the pressing mechanism in the present invention fixes the PE molded sheet, the pressing mechanism also drives the connecting frame located on the upper side of the PE molded sheet to move downward, and the connecting frame located on the upper side drives the connecting frame located on the lower side to move toward the PE molded sheet through the synchronous locking group until the grinding discs on the upper and lower sides contact the PE molded sheet, thereby realizing the integrated drive of the pressing of the PE molded sheet and the synchronous movement of the connecting frames on the upper and lower sides, thereby improving the convenience of trimming the PE molded sheet.

[0024] 3. When the end pressure plates in the present invention are pressed against the PE molded sheet, the positioning group centers the PE molded sheet along its width direction, so that the two end pressure plates can fully press and fix the PE molded sheet, further improving the stability of the PE molded sheet during polishing. At the same time, the integrated driving function of the end pressure plates, the positioning group and the upper and lower connecting frames is also realized, greatly improving the efficiency of fixing the PE molded sheet.

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0034] Refer to Figure 1 , a demoulding and trimming treatment device for a PE molded sealing and noise reduction filling block, including a base 1. Two support platforms 2 and two support frames 3 are symmetrically arranged along the width direction of the top of the base 1. The two support platforms 2 are located between the two support frames 3. The support frame 3 has a structure in the shape of a Chinese character 'ri', and the support platform 2 has an L-shaped structure.

[0035] Refer to Figure 1A pressing mechanism 4 for fixing the PE molded sheet 6 is installed on the two support platforms 2, a limiting block is installed at one end of the support platform 2, and two double-sided trimming mechanisms 5 arranged in a mirror image along the center of the base 1 are installed on the two support frames 3. The double-sided trimming mechanisms 5 are used to trim the upper and lower end surfaces of the PE molded sheet 6.

[0036] In the initial state, one of the double-sided trimming mechanisms 5 is located in the middle of the support frame 3, and the other double-sided trimming mechanism 5 is located at one end of the support frame 3, so that when the PE molded sheet 6 is trimmed later, there is always a double-sided trimming mechanism 5 located in the middle of the PE molded sheet 6 to support the PE molded sheet 6.

[0037] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The double-sided finishing mechanism 5 includes two upper and lower connecting frames 50 connected together between the middle horizontal sections of the two supporting frames 3. Two grinders arranged along the length direction are installed on the opposite surfaces of the upper and lower connecting frames 50. The grinder is equipped with a grinding disc 51 for trimming the PE molded sheet 6. A guide groove 52 that runs through the upper and lower parts is opened in the middle horizontal section of the supporting frame 3. A connecting seat 53 is slidably connected in the guide groove 52. The connecting seat 53 is a cavity structure. The upper and lower connecting frames 50 are slidably connected to the upper and lower sides of the connecting seat 53 through a synchronous locking group 54. A longitudinal driving group (such as an electric slider) is installed on the connecting seat 53 to drive it to drive the connecting frame 50 to move along the length direction of the PE molded sheet 6. A transverse driving group 55 is installed on the base 1 to drive the connecting frame 50 to drive the grinding disc 51 to move along the width direction of the PE molded sheet 6 for grinding.

[0038] After the PE molded sheet 6 is placed on the two support platforms 2, the PE molded sheet 6 is fixed by the pressing mechanism 4. At the same time, the pressing mechanism 4 drives the connecting frame 50 located on the upper side of the PE molded sheet 6 to move downward, and the connecting frame 50 located on the upper side drives the connecting frame 50 located on the lower side to move toward the PE molded sheet 6 through the synchronous locking group 54, until the grinding discs 51 on the upper and lower sides both contact the PE molded sheet 6, thereby realizing the integrated drive of the pressing of the PE molded sheet 6 and the synchronous movement of the connecting frames 50 on the upper and lower sides, thereby improving the convenience of finishing.

[0039] When trimming the PE molded sheet 6, the double-sided trimming mechanism 5 located in the middle supports the middle part of the PE molded sheet 6 through the grinding discs 51 on the upper and lower sides, so as to prevent the middle part of the PE molded sheet 6 from being suspended in the air and sinking downward under its own weight, thereby affecting the trimming quality. Another double-sided trimming mechanism 5 is started, and the grinder drives the grinding disc 51 to grind the PE molded sheet 6. At the same time, the longitudinal drive group and the transverse drive group 55 in the double-sided trimming mechanism 5 cooperate to drive the connecting frames 50 on the upper and lower sides to move synchronously. The grinding discs 51 on the upper and lower sides support each other when grinding the PE molded sheet 6, thereby improving the stability of the grinding and trimming process and further improving the trimming quality and efficiency.

[0040] When the double-sided trimming mechanism 5 that is in grinding work moves to the middle part of the PE molded sheet 6, it is arranged in an alternating manner with the double-sided trimming mechanism 5 that was not working before to grind the middle part of the PE molded sheet 6 together. After that, the previous double-sided trimming mechanism 5 that has completed the grinding work stops working and supports the middle part of the PE molded sheet 6, and the other double-sided trimming mechanism 5 starts to move to grind and trim the remaining part of the PE molded sheet 6.

[0041] In summary, the two double-sided trimming mechanisms 5 work alternately, which not only ensures that the middle of the PE molded sheet 6 is always stably supported during the grinding and trimming process, but also further improves the stability and efficiency of the grinding and trimming through the mutual support of the grinding discs 51 on the upper and lower sides.

[0042] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The pressing mechanism 4 includes guide grooves 40 provided on the vertical sections of the opposite surfaces of the two support platforms 2, and an end pressure plate 41 that slides up and down is connected to the guide groove 40. A lifting driving source (such as an electric slider) for driving the end pressure plate 41 is installed on the support platform 2. A synchronous lifting group 42 is installed on the end pressure plate 41 to drive the connecting frame 50 located on the upper side to move synchronously during its movement. The horizontal sections of the two support platforms 2 are jointly equipped with a positioning group 43 that cooperates to center the PE molded plate 6.

[0043] See also Figure 4 The rubber gasket installed at the bottom of the end pressing plate 41 is used to protect the PE molded sheet 6 when the end pressing plate 41 presses the PE molded sheet 6.

[0044] See also Figure 3 , Figure 4 and Figure 5The synchronous locking group 54 includes a gear 540 rotatably connected to the inner wall of the connecting seat 53 and two racks 541 slidably connected to the upper and lower sides of the connecting seat 53 respectively. The two racks 541 are arranged along the width direction of the guide groove 52 and the racks 541 are meshed with the gears 540 for transmission. After the rack 541 passes through the connecting seat 53, a T-shaped slider 542 is fixedly installed. The end surface of the connecting frame 50 close to the connecting seat 53 is provided with a T-shaped slot 543 slidably connected to the corresponding T-shaped slider 542.

[0045] When the connecting frame 50 on the upper side moves downward, it drives the rack 541 connected to it to move downward. The rack 541 drives the rack 541 on the lower side to move upward through the meshing transmission with the gear 540. The rack 541 on the lower side drives the connecting frame 50 on the lower side to move upward through the T-shaped slider 542 connected to it, so that the connecting frames 50 on the upper and lower sides can synchronously drive the grinding discs 51 connected to them to contact the PE molded sheet 6, thereby improving the grinding and finishing efficiency.

[0046] See also Figure 4 Supplementary insert strips 544 are installed on the upper and lower sides of the connecting seat 53, and the corresponding T-shaped slider 542 is provided with a socket 545 that is plugged into and cooperates with the supplementary insert strip 544. When the connecting frame 50 moves toward the connecting seat 53, the supplementary insert strip 544 is inserted into the socket 545, thereby increasing the connection stability between the T-shaped slider 542 and the connecting seat 53.

[0047] See also Figure 1 and Figure 4 The synchronous lifting group 42 includes a push-pull rod 420 connected to the top of the end pressure plate 41 and sliding along its length direction. A rectangular groove 421 is opened on the top of the guide groove 40 and passes through the top of the support platform 2. A through groove 422 is opened on the connecting frame 50 and passes through the T-shaped groove 543 from top to bottom. The top of the push-pull rod 420 passes through the rectangular groove 421 and the through groove 422. Two blocks 423 arranged vertically are installed on the push-pull rod 420. The connecting frame 50 is located between the upper and lower blocks 423. Balls are installed on the opposite surfaces of the two blocks 423. The balls are in rolling contact with the connecting frame 50, thereby reducing the friction between the connecting frame 50 and the blocks 423 during movement.

[0048] The PE molded sheet 6 is inserted between the end pressing plate 41 and the horizontal section of the support platform 2, and the end pressing plate 41 is driven downward by the lifting drive source to fix the PE molded sheet 6. During the downward movement of the end pressing plate 41, the positioning group 43 centers the PE molded sheet 6 along its width direction, so that the two end pressing plates 41 can fully press and fix the PE molded sheet 6, and the push-pull rod 420 is driven downward while the end pressing plate 41 moves downward. The push-pull rod 420 drives the connecting frame 50 on the upper side to move downward through the block 423, and the connecting frame 50 on the upper side drives the connecting frame 50 on the lower side to move toward the PE molded sheet 6 through the synchronous locking group 54. When the end pressing plate 41 is pressed against the PE molded sheet 6, the connecting frames 50 on the upper and lower sides drive the corresponding grinding discs 51 on the upper and lower sides to press against the surface of the PE molded sheet 6, thereby realizing the function of integrated driving of the end pressing plate 41, the positioning group 43 and the connecting frames 50 on the upper and lower sides, thereby greatly improving the efficiency of fixing the PE molded sheet 6.

[0049] Through the sliding connection between the push-pull rod 420 and the end pressure plate 41, the rectangular groove 421, and the through groove 422, the push-pull rod 420 can move along the length direction of the PE molded sheet 6 with the connecting frame 50, and avoid the push-pull rod 420 affecting the movement of the connecting frame 50 along the width direction of the PE molded sheet 6, so that the connecting frame 50 drives the grinding disc 51 to always be in close contact with the end surface of the PE molded sheet 6.

[0050] See also Figure 3 and Figure 4 The positioning group 43 includes a push plate 430 slidably connected to the horizontal section of the support platform 2. The push plate 430 is connected to the vertical section of the support platform 2 through evenly arranged push springs 431. A receiving groove 432 is provided at the bottom of the support platform 2. A locking assembly is installed in the receiving groove 432. The locking assembly is used to pull the push plate 430 to move toward the vertical section of the support platform 2 when the end pressure plate 41 moves upward.

[0051] See also Figure 3 and Figure 4 The locking assembly includes a circular strip 433 installed on the push plate 430 and slidingly inserted into the receiving groove 432. A wedge block 434 is installed on the lower end surface of one end of the circular strip 433 located in the receiving groove 432. An L-shaped rod 435 is installed on the lower end surface of the end pressure plate 41 and slides into the receiving groove 432 and the circular strip 433. A ball is installed on the end of the horizontal section of the L-shaped rod 435. When the L-shaped rod 435 moves upward, its horizontal section end is used to squeeze and push the wedge block 434.

[0052] In the initial state, the horizontal section end of the L-shaped rod 435 contacts the inclined surface of the wedge block 434. When the PE molded sheet 6 is placed between the two push plates 430, the end pressure plate 41 moves downward to press the PE molded sheet 6, and the end pressure plate 41 drives the L-shaped rod 435 to move downward. When the L-shaped rod 435 moves downward until its horizontal section is separated from the wedge block 434, the push plate 430 approaches the side of the end pressure plate 41 under the elastic force of the push spring 431. The two push plates 430 center the PE molded sheet 6 along its width direction under the elastic force of the push spring 431, so that the two end pressure plates 41 can fully press and fix the PE molded sheet 6.

[0053] When the end pressure plate 41 moves upward after the trimming of the PE molded sheet 6 is completed, the end pressure plate 41 drives the L-shaped rod 435 to move upward. During the upward movement of the L-shaped rod 435, the ball at its end contacts the inclined surface of the wedge block 434. The L-shaped rod 435 pushes the wedge block 434 to drive the circular strip 433 to move. The circular strip 433 drives the push plate 430 to squeeze the push spring 431 and move toward the vertical section of the support platform 2 to disengage from the PE molded sheet 6, so as to facilitate the removal of the PE molded sheet 6 and the insertion of the next PE molded sheet 6.

[0054] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The lateral drive group 55 includes a guide slot 550 connected to the guide slot 52 and opened on the side of the middle horizontal section of the support frame 3 away from the support platform 2. A supplementary block 551 slidably connected to the guide slot 550 is installed on the side wall of the connecting seat 53. A C-shaped frame 552 is slidably connected to the base 1. The two support frames 3 are located between the two vertical sections of the C-shaped frame 552. An insertion rod 553 slidably connected to the vertical section corresponding to the C-shaped frame 552 is fixedly installed on the supplementary block 551. A limiting block 554 is installed on the end of the insertion rod 553 away from the supplementary block 551. A lateral drive source component for driving the C-shaped frame 552 to move is installed on the top of the base 1.

[0055] See also Figure 1 , Figure 2 and Figure 3 The lateral driving source assembly includes a mounting groove 555 opened on the base 1, and a U-shaped seat 556 sliding along the width direction of the base 1 is connected to the mounting groove 555. A plug plate 557 slidingly inserted between two vertical sections of the U-shaped seat 556 is fixedly installed at the bottom of the horizontal section of the U-shaped frame 552.

[0056] An external electric slider is installed on the C-shaped seat 556 to drive it to move back and forth. The C-shaped seat 556 drives the C-shaped frame 552 to move back and forth along the width direction of the PE molded sheet 6 through the insertion of the C-shaped seat 556 and the plug-in plate 557. The two vertical sections of the C-shaped frame 552 alternately collide with the corresponding two ends of the connecting frame 50, thereby driving the two connecting frames 50 to move along the width direction of the PE molded sheet 6. The connecting frame 50 drives the grinding disc 51 to move and grind the PE molded sheet 6 laterally. The longitudinal drive group drives the connecting seat 53 to move along the length direction of the PE molded sheet 6. The connecting seat 53 drives the connecting frames 50 and the grinding disc 51 on the upper and lower sides to move and grind the PE molded sheet 6 longitudinally. When the connecting seat 53 moves, the C-shaped frame 552 is synchronously driven to move along the length direction of the PE molded sheet 6 through the plug-in rod 553, thereby realizing the synchronous longitudinal and lateral movement of the connecting frames 50 on the upper and lower sides, so that the grinding disc 51 can evenly grind and trim the PE molded sheet 6.

[0057] The present invention also provides a demolding and trimming method for a PE molded sealing noise reduction filling block, comprising the following steps: S1, placement and fixation: inserting the PE molded sheet 6 between the end pressing plate 41 and the horizontal section of the support platform 2, driving the end pressing plate 41 downward by a lifting drive source to fix the PE molded sheet 6, and in the process of the end pressing plate 41 moving downward, the positioning group 43 centers the PE molded sheet 6 along its width direction.

[0058] S2, moving and locking: the end pressure plate 41 drives the connecting frame 50 located on the upper side of the PE molded sheet 6 to move downward through the synchronous lifting group 42, and the connecting frame 50 located on the upper side drives the connecting frame 50 located on the lower side to move toward the PE molded sheet 6 through the synchronous locking group 54 until the grinding discs 51 on the upper and lower sides collide with the PE molded sheet 6.

[0059] S3, alternating support and polishing: the double-sided trimming mechanism 5 located in the middle supports the middle part of the PE molded sheet 6 through the polishing discs 51 on its upper and lower sides, and another double-sided trimming mechanism 5 is started.
