Description

Technical Field

[0001] This utility model relates to the field of thermoforming equipment technology, and in particular to a food container conveying component for a thermoforming machine. Background Technology

[0002] Vacuum forming technology is widely used in the production of disposable plastic lunch boxes. During the production process, the rolled plastic sheet needs to be continuously and stably transported to the subsequent heating and forming station through the conveying component. The operating accuracy and cleaning ability of the conveying component are directly related to the forming quality and appearance of the final lunch box.

[0003] However, existing conveying components for vacuum forming machines have certain technical limitations in practical use. Due to the thinness and flexibility of plastic sheets, they are prone to deviation during long-distance transport due to uneven force. Existing guiding devices use a fixed structure, which not only makes it difficult to adapt to sheets of different widths, but also easily causes hard scratches on the edges of the sheets during the correction process, leading to material damage. More seriously, dust and fine impurities are inevitable in the production workshop environment. Plastic sheets easily absorb these impurities during transport, and existing conveying components lack an effective online cleaning mechanism. This causes sheets with impurities to directly enter the high-temperature vacuum forming process, where the impurities melt into the walls of the food containers, forming permanent spots or bumps, which greatly reduces the yield and hygiene level of the finished food containers.

[0004] Therefore, this utility model proposes a food container conveying component for a blister packaging machine to address the shortcomings of the prior art. Utility Model Content

[0005] In view of the problems existing in the blister packaging machine's food container conveying assembly, such as poor adjustment flexibility of the guiding mechanism, easy scratching of the plastic sheet surface during correction, and lack of online cleaning mechanism leading to impurities adsorbed during conveying entering the blister packaging process and affecting the appearance quality and yield of the finished food container, this utility model aims to provide a blister packaging machine food container conveying assembly with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a food container conveying assembly for a blister packaging machine, including a conveyor and support legs symmetrically installed on the bottom surface of the conveyor. An mounting plate is fixedly connected to the top rear side of the conveyor, and a material guiding and adjusting component and a cleaning component are set on the mounting plate and in the conveyor area.

[0007] An electric push rod is fixedly connected to the top front side of the mounting plate. A movable plate is fixedly connected to the output end of the electric push rod. A first mounting column is symmetrically installed on the top rear side of the movable plate. A connecting plate is rotatably connected to the outer wall of the first mounting column. A second mounting column is rotatably connected to the end of the connecting plate away from the first mounting column. A first slider is fixedly connected to the bottom surface of the second mounting column. The first slider is slidably connected to the inner walls of the left and right sides of the mounting plate. A guide plate is fixedly connected to the bottom surface of the first slider. A rotating roller is rotatably connected to the rear side of the guide plate.

[0008] Furthermore, a fixing plate is fixedly connected to the top rear side of the mounting plate and the bottom rear side of the conveyor. A movable rod is slidably connected to the fixing plate near the bottom of the inner wall of the conveyor, and soft brushes are fixedly installed on the opposite sides of the two movable rods.

[0009] Preferably, a motor is fixedly connected to the side of the fixed plate away from the conveyor, and a rotating rod is fixedly connected to the output end of the motor.

[0010] Preferably, a connecting rod is rotatably connected to the top of the inner wall of the conveyor near the fixed plate, and a second slider is rotatably connected to the end of the rotating rod away from the motor. The second slider is slidably connected to the inner wall of the middle part of the connecting rod.

[0011] Preferably, a slotted plate is fixedly connected to the center of the moving rod and the side close to the connecting rod, and a third slider is slidably connected to the inner wall of the slotted plate. The inner wall of the third slider is rotatably connected to the end of the connecting rod away from the top of the fixed plate.

[0012] Preferably, the inner walls on both sides of the guide plate are designed as inclined surfaces to guide the edges of the plastic sheet, with the inclined surfaces gradually tapering from the outside to the inside.

[0013] Preferably, the inner walls on both the left and right sides of the mounting plate are provided with grooves for accommodating the first slider, and the first slider moves horizontally reciprocating along the length of the groove.

[0014] Preferably, bearings are fitted on the outer walls of both the first and second mounting columns, and the connecting plate is rotatably connected to the first and second mounting columns respectively through the bearings.

[0015] Preferably, the length of the soft brush bristles is greater than or equal to the vertical distance between the conveyor conveying plane and the bottom surface of the moving rod, and the soft brush covers the conveyor conveying width along the length of the moving rod.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problems of easy deviation during plastic sheet conveying and scratches and damage to the material surface caused by hard contact during guidance and limiting in the prior art by setting a material guiding mechanism on the rear side of the conveyor, using an electric push rod and connecting rod assembly to drive the material guiding plate to adjust its horizontal position, and setting a rotating roller connected to the rear side of the material guiding plate. It achieves the effect of accurately and automatically centering and guiding plastic sheets of different widths, while using the rotating roller to convert the sliding friction between the plastic sheet and the material guiding plate into rolling friction, thereby effectively reducing the wear on the surface of the plastic sheet and ensuring smooth conveying and material integrity.

[0018] 2. This utility model solves the problem in the prior art where cleaning mechanisms are set on the upper and lower sides of the conveyor. By using a motor-driven rotating rod and connecting rod assembly, the rotational motion of the motor is converted into the horizontal reciprocating linear motion of the moving rod and the soft brush fixed on the moving rod. This solves the problem that dust and impurities easily adhere to the surface of the plastic sheet during the conveying process, which leads to appearance defects in the blister-formed lunch box. It achieves fully automatic and thorough reciprocating cleaning of the upper and lower surfaces of the plastic sheet during the conveying process, effectively removing foreign objects attached to the surface and preventing impurities from embedding into the lunch box wall during blister forming, thus significantly improving the appearance and production qualification rate of the finished blister lunch box.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] Example:

[0029] Please refer to Figures 1 to 6 This utility model provides a food container conveying component for a blister packaging machine, which aims to solve the problems of easy deviation and wear during the conveying of blister materials and poor product surface quality due to the lack of an automatic surface cleaning device in the prior art.

[0030] Please refer to Figure 1 and Figure 2 The food container conveying assembly of the blister forming machine includes a conveyor 1, a cleaning mechanism 5, and support legs 2 symmetrically installed on the bottom surface of the conveyor 1. A mounting plate 401 is fixedly connected to the rear top surface of the conveyor 1 by bolts. The conveyor 1 is used as a conveying and carrying platform for plastic sheets 3 that need to be blistered into food containers. The support legs 2 are used to support and fix the conveyor 1. The mounting plate 401 is used to provide an installation base for the subsequent material guiding mechanism 4.

[0031] Please refer to Figure 2 , Figure 3 and Figure 4An electric push rod 402 is bolted to the top front side of the mounting plate 401. A movable plate 403 is fixedly connected to the output end of the electric push rod 402. A first mounting post 404 is symmetrically mounted on the top rear side of the movable plate 403. A connecting plate 405 is rotatably connected to the outer wall of the first mounting post 404. A second mounting post 406 is rotatably connected to the end of the connecting plate 405 away from the first mounting post 404. To ensure smooth rotation, bearings are fitted on the outer walls of both the first mounting post 404 and the second mounting post 406. The connecting plate 405 is rotatably connected to the first mounting post 404 and the second mounting post 406 respectively through the bearings. A first slider 407 is fixedly connected to the bottom surface of the second mounting post 406. Openings are made on the inner walls of both the left and right sides of the mounting plate 401. There is a groove for accommodating the first slider 407. The first slider 407 is slidably connected to the inner walls of the left and right sides of the mounting plate 401 and moves horizontally back and forth along the length of the groove. The bottom surface of the first slider 407 is fixedly connected to a guide plate 408. The inner walls of the left and right sides of the guide plate 408 are designed as inclined surfaces to guide the edge of the plastic sheet 3. The inclined surfaces gradually shrink from the outside to the inside. The rear side of the guide plate 408 is rotatably connected to a rotating roller 409. When the electric push rod 402 drives the moving plate 403 to move, the guide plate 408 is adjusted to a horizontal position through the transmission of the connecting plate 405. The setting of the rotating roller 409 converts the sliding friction between the plastic sheet 3 and the guide plate 408 into rolling friction, thereby achieving low-wear and precise guidance of the plastic sheet 3.

[0032] As a preferred embodiment, in order to achieve automatic cleaning of the surface of the plastic sheet 3, please refer to... Figure 5 and Figure 6 The top rear surface of the mounting plate 401 and the bottom rear surface of the conveyor 1 are both fixedly connected to the fixing plate 501 by bolts. The fixing plate 501 is slidably connected to the bottom of the inner wall of the conveyor 1. Soft brushes 508 are fixedly installed on the opposite surfaces of the two moving rods 507. The bristle length of the soft brushes 508 is greater than or equal to the vertical distance between the conveying plane of the conveyor 1 and the bottom surface of the moving rods 507, and the soft brushes 508 cover the conveying width of the conveyor 1 along the length direction of the moving rods 507.

[0033] As a further preferred embodiment, in order to drive the soft brush 508 to reciprocate, a motor 509 is fixedly connected to the side of the fixed plate 501 away from the conveyor 1, and a rotating rod 503 is fixedly connected to the output end of the motor 509. A connecting rod 502 is rotatably connected to the top of the inner wall of the fixed plate 501 near the conveyor 1. A second slider 504 is rotatably connected to the end of the rotating rod 503 away from the motor 509. The second slider 504 is slidably connected to the inner wall of the middle part of the connecting rod 502. A slotted plate 505 is fixedly connected to the center of the moving rod 507 and the side near the connecting rod 502. A third slider 506 is slidably connected to the inner wall of the slotted plate 505. The inner wall of the third slider 506 is rotatably connected to the end of the connecting rod 502 away from the top connection point of the fixed plate 501. The rotating rod 503 is driven to rotate by the motor 509, and in conjunction with the swing of the connecting rod 502, the moving rod 507 is driven to perform linear reciprocating motion.

[0034] Working principle: When it is necessary to guide and limit the conveyed plastic sheet 3, the electric push rod 402 is activated. The output end of the electric push rod 402 drives the moving plate 403 to move. The moving plate 403 drives the connecting plate 405 to rotate through the first mounting column 404. The connecting plate 405 pulls or pushes the first slider 407 to slide in the groove of the mounting plate 401 through the second mounting column 406, thereby driving the guide plate 408 to make horizontal position adjustment to adapt to plastic sheets 3 of different widths. When the plastic sheet 3 passes through the area of ​​the guide plate 408, the inclined surface of the inner wall of the guide plate 408 guides the edge of the plastic sheet 3. At the same time, the rotating roller 409 rotates with the movement of the plastic sheet 3, changing the friction form to rolling friction.

[0035] When it is necessary to clean the surface of the plastic sheet 3, the motor 509 is started. The motor 509 drives the rotating rod 503 to make a circular motion. The rotating rod 503 drives the second slider 504 to slide back and forth on the inner wall of the middle part of the connecting rod 502, forcing the connecting rod 502 to swing periodically around the top fulcrum. The swing of the bottom end of the connecting rod 502 drives the moving rod 507 to make a horizontal linear reciprocating motion at the bottom of the fixed plate 501 through the cooperation of the third slider 506 and the slot plate 505, thereby driving the two sets of soft brushes 508 to thoroughly clean the upper and lower surfaces of the plastic sheet 3.
