Description

Technical Field

[0001] This utility model relates to the field of vacuum forming machine technology, and more specifically, to a baking vacuum forming mechanism for a vacuum forming machine. Background Technology

[0002] Vacuum forming machines, also known as thermoforming machines, are machines that use heated and plasticized thermoplastic plastic rolls such as PVC, PE, PP, PET, and HIPS to form various shapes of high-end packaging boxes, frames, and other products. They utilize the vacuum suction generated by a vacuum pump to mold heated and softened thermoplastic plastic sheets such as PVC and PET into various shapes of vacuum covers, blister trays, and blister packs.

[0003] Existing vacuum forming machines require the plastic sheet to be fixed on top of the forming mold first, then softened by a baking device, and finally adhered to the surface of the mold by a vacuum pump to complete the vacuum forming process. However, when the mold takes several to tens of seconds to vacuum form the film, it is impossible to load and unload the material simultaneously during the forming process, which reduces the working efficiency of the vacuum forming machine.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

The connecting frame is sleeved with the fixed tube. At the same time, an external vacuum pump creates a negative pressure inside the forming frame, and the reset motor drives the cylindrical gear to rotate clockwise, causing the moving block to move to the right along the outer side of the second guide rail. During the vacuum forming process, the fixed tube drives the control cylinder and the connecting frame to move to the right along the first guide rail. After the vacuum forming is completed, the control cylinder drives the connecting frame to move vertically downward, thus separating the connecting frame from the fixed tube. During the vacuum forming process, the worker can simultaneously load and unload materials in the loading and unloading area, improving the working efficiency of the vacuum forming machine.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figures 1 to 8As shown, this utility model provides a baking and thermoforming mechanism for a thermoforming machine, including a fixed column 1, a base 101 fixedly connected to the bottom of the fixed column 1, a forming component 2 installed on the top of the outer side of the fixed column 1, a fixed plate 102 fixedly sleeved on the middle of the outer side of the fixed column 1, a baking component 3 installed on the top of the fixed column 1, a fixed component 6 installed on the top of the forming component 2, a negative pressure component 4 installed on the front of the top of the fixed plate 102, and a reset component 5 installed on the front of the fixed plate 102. The negative pressure component 4 includes a first guide rail 401 fixedly connected to the top of the fixed plate 102, a movable frame 402 slidably sleeved on the outer side of the first guide rail 401, a control cylinder 403 installed on the top of the movable frame 402, a connecting frame 404 fixedly connected to the top of the piston rod of the control cylinder 403, a connecting pipe 405 fixedly connected to the front of the connecting frame 404, a negative pressure pipe fixedly connected to the outer side of the connecting pipe 405, and the other end of the negative pressure pipe connected to a vacuum pump. The reset assembly 5 includes a second guide rail 501 fixedly connected to the front of the fixed disk 102 and a meshing tooth 121 disposed on the top of the fixed disk 102. A moving block 502 is slidably sleeved on the outer side of the second guide rail 501. A fixed plate 503 is fixedly connected to the top of the moving block 502. A reset motor 504 is fixedly connected to the front of the fixed plate 503. A cylindrical gear 505 is fixedly connected to the output shaft of the reset motor 504. A push plate 506 is fixedly connected to the top of the fixed plate 503. The cylindrical gear 505 meshes with the meshing tooth 121. The connecting frame 404 and the fixed tube 204 at the bottom of the front forming frame 202 are located in the same vertical direction.

[0029] In this embodiment, the back of the molding component 2 is the loading and unloading area, the left side of the molding component 2 is the baking and heating area, the front of the molding component 2 is the negative pressure vacuum forming area, and the right side of the molding component 2 is the cooling area. The worker places the plastic sheet on the top of the back molding frame 202, and drives the connecting block 602 to move downward through the piston rod of the fixed cylinder 601. Then, the pressing frame 603 presses and fixes the plastic sheet. The rotary motor 104 drives the drive gear 105 to rotate, and drives the rotating disk 201 to rotate counterclockwise through the meshing action with the ring gear 205. When the plastic sheet rotates to the bottom of the baking component 3, the heating rod 303 and the fan 304 are started. The heating rod 303 heats the nearby air, and the fan 304 blows the hot air to the surface of the plastic sheet to soften the plastic sheet.

[0030] The reset motor 504 drives the cylindrical gear 505 to rotate counterclockwise. Through the meshing action with the meshing gear 121, the moving block 502 drives the fixed plate 503 and the push plate 506 to move to the left along the outer side of the second guide rail 501. As a result, the push plate 506 pushes the movable frame 402 and the control cylinder 403 to move to the left along the outer side of the first guide rail 401, so that the control cylinder 403 is in contact with the left side of the first guide rail 401, thereby completing the reset of the control cylinder 403. When the molding frame 202 with the softened plastic sheet fixed on the top rotates to directly above the control cylinder 403, the piston rod of the control cylinder 403 pushes the connecting... The connecting frame 404 moves vertically upward and engages with the fixing tube 204. Simultaneously, an external vacuum pump creates a negative pressure inside the forming frame 202, and the reset motor 504 drives the cylindrical gear 505 to rotate clockwise, causing the moving block 502 to move to the right along the outer side of the second guide rail 501. During the vacuum forming process, the fixing tube 204 drives the control cylinder 403 and the connecting frame 404 to move to the right along the first guide rail 401. After the vacuum forming is completed, the control cylinder 403 drives the connecting frame 404 to move vertically downward, thus separating the connecting frame 404 from the fixing tube 204.

[0031] The molding component 2 includes a rotating disk 201, and molding frames 202 are fixedly connected to the top four sides of the rotating disk 201. A mold core 203 is installed on the inner side of the molding frame 202.

[0032] The rotating disk 201 is movably connected to the fixed column 1. The surface of the mold core 203 is provided with multiple micro holes for vacuuming. After vacuuming, the softened plastic sheet adheres to the surface of the mold core 203 to complete the thermoforming process.

[0033] Among them, a fixing tube 204 is fixedly connected to the middle of the bottom of the forming frame 202, and the fixing tube 204 is compatible with the connecting frame 404.

[0034] The bottom outer edge of the fixing tube 204 is chamfered, and the top inner edge of the connecting frame 404 is chamfered, so that the connecting frame 404 can be fitted onto the outside of the fixing tube 204 to avoid collisions.

[0035] Among them, a ring gear 205 is fixedly connected to the middle of the bottom of the rotating disk 201, a support plate 103 is fixedly connected to the right side of the fixed column 1, a rotary motor 104 is fixedly connected to the bottom of the support plate 103, and a drive gear 105 is fixedly connected to the output shaft of the rotary motor 104. The drive gear 105 and the ring gear 205 mesh with each other, and the diameter of the drive gear 105 is smaller than the diameter of the ring gear 205.

[0036] The rotating motor 104 drives the drive gear 105 to rotate clockwise, and through the meshing action with the ring gear 205, drives the rotating disk 201 to rotate counterclockwise, thereby driving the molding component 2 to rotate around the fixed column 1.

[0037] The baking assembly 3 includes a top plate 301 fixedly connected to the top of the fixed column 1. A mounting frame 302 is fixedly connected to the inner side of the top plate 301. The mounting frame 302 and the left forming frame 202 are located in the same vertical direction. A heating rod 303 is installed at the bottom of the inner side of the mounting frame 302. A fan 304 is installed in the middle of the inner side of the mounting frame 302. A filter screen 305 is fixedly connected to the top of the inner side of the mounting frame 302.

[0038] When the plastic sheet rotates to the bottom of the baking assembly 3, the heating rod 303 and the fan 304 are activated. The heating rod 303 heats the surrounding air, and the fan 304 blows the hot air toward the surface of the plastic sheet, softening it.

[0039] The fixing component 6 includes a fixing cylinder 601 fixedly connected to the bottom of the rotating disk 201. A connecting block 602 is fixedly connected to the top of the piston rod of the fixing cylinder 601, and a pressing frame 603 is fixedly connected to the inner side of the connecting block 602.

[0040] After the plastic sheet is placed, the fixing cylinder 601 drives the piston rod to retract, so that the pressing frame 603 can press and fix the plastic sheet.

[0041] Working principle and usage process of this utility model:

[0042] The back of the molding component 2 is the loading and unloading area, the left side of the molding component 2 is the baking and heating area, the front of the molding component 2 is the negative pressure vacuum forming area, and the right side of the molding component 2 is the cooling area. The worker places the plastic sheet on the top of the back molding frame 202, and drives the connecting block 602 to move downward through the piston rod of the fixed cylinder 601. Then, the pressing frame 603 presses and fixes the plastic sheet. The rotary motor 104 drives the drive gear 105 to rotate, and through the meshing action with the ring gear 205, drives the rotating disk 201 to rotate counterclockwise. When the plastic sheet rotates to the bottom of the baking component 3, the heating rod 303 and the fan 304 are activated. The heating rod 303 heats the surrounding air, and the fan 304 blows the hot air onto the surface of the plastic sheet to soften it.

[0043] The reset motor 504 drives the cylindrical gear 505 to rotate counterclockwise. Through the meshing action with the meshing gear 121, the moving block 502 drives the fixed plate 503 and the push plate 506 to move to the left along the outer side of the second guide rail 501. As a result, the push plate 506 pushes the movable frame 402 and the control cylinder 403 to move to the left along the outer side of the first guide rail 401, so that the control cylinder 403 is in contact with the left side of the first guide rail 401, thereby completing the reset of the control cylinder 403. When the molding frame 202 with the softened plastic sheet fixed on the top rotates to directly above the control cylinder 403, the piston rod of the control cylinder 403 pushes the connecting... The connecting frame 404 moves vertically upward and engages with the fixing tube 204. Simultaneously, an external vacuum pump creates a negative pressure inside the forming frame 202, and the reset motor 504 drives the cylindrical gear 505 to rotate clockwise, causing the moving block 502 to move to the right along the outer side of the second guide rail 501. During the vacuum forming process, the fixing tube 204 drives the control cylinder 403 and the connecting frame 404 to move to the right along the first guide rail 401. After the vacuum forming is completed, the control cylinder 403 drives the connecting frame 404 to move vertically downward, thus separating the connecting frame 404 from the fixing tube 204.

[0044] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
