Description
本发明涉及制鞋设备领域技术，尤其是指一种带回温的冷冻定型机。
在制鞋工艺中，为了使鞋子脱楦后不易变形，通常会采用冷冻定型机进行冷冻定型。然而现有的制鞋用冷冻定型机，经冷冻室冷冻定型后的鞋子不经任何处理就被直接输送出去，由于冷定型后的鞋子温度很低，当鞋子与外界空气接触后，鞋子表面会凝结水珠，这样会增加了鞋子的水分含量，若直接包装，则会导致鞋子在储藏过程容易发霉变质，影响鞋子的质量。
藉此，中国已有发明专利（专利号201520143335.9）公开一种可以使鞋子离开冷冻柜后迅速回温的新型冷冻定型机，但此类冷冻定型机存在以下缺陷：由于此类冷冻定型机在出料口位置设置了上风刀和下风刀，由上风刀从上往下吹形成第一道暖风墙，由下风刀从下往上吹形成第二道暖风墙。这样第一道暖风墙和第二道暖风墙的气流形成对冲，导致不能完全和快速将冷热交换所产生之水分带走。其次，两股暖风上下对冲会形成乱流，即使传统设备已经在冷冻区域和暖风区域之间设置隔离墙，但隔离墙并不是完全密封，在气流上下对冲时，亦会有部分暖风会冲入冷冻区域从而降低冷冻效果和加大能耗。
有鉴于此，本发明针对现有技术存在之缺失，其主要目的是提供一种带回温的冷冻定型机，直接将冷却蒸发器后得到的暖风回用至出料口，在出料口形成快速流动的暖风区域，使冷冻后的鞋子迅速回温，解决传统机器输出冷冻鞋子与空气接触产生凝露而无法直接包装和发霉问题。
为实现上述目的，本发明采用如下之技术方案：
一种带回温的冷冻定型机，包括主体机架，该主体机架分为上层、中层、下层，该中层设有用于定型鞋子的冷冻柜，冷冻柜的左右外侧设有蒸发器，冷冻柜的前后端分别设有进料口和出料口，并于冷冻柜的底面安装有用于将鞋子从进料口输送至出料口的传送带；其特征在于：所述出料口的上侧设有暖风进口，出料口的下侧设有暖风出口，于主体机架上层设有第一风机和第二风机，该第一风机除用于冷却蒸发器外，还同时将冷却蒸发器所产生的暖风输送至暖风进口，第二风机连通暖风出口将出料口的暖风迅速吸走，从而在出料口位置形成快速流动的暖风墙。
作为一种优选方案，所述第一风机与暖风进口之间设置鼓风通道，所述第二风机与暖风出口之间设置吸风通道，该鼓风通道与吸风通道是软管，或者是采用隔离板在主体机架内隔离出的通道。
作为一种优选方案，所述冷冻柜的进料口和出料口设有可防止冷气泄漏的隔离带或者电动门。
作为一种优选方案，所述暖风进口与暖风出口之间形成的暖风区域与冷冻柜内的冷风区域之间设有隔离带或者电动门。
作为一种优选方案，所述主体机架上设有控制系统，主体机架压缩机、冷凝器、蒸发器、传送带的拖动电机以及各风机均与该控制系统电相连。
一种带回温的冷冻定型机，包括主体机架，该主体机架分为上层、中层、下层，该中层设有用于定型鞋子的冷冻柜，冷冻柜的左右外侧设有蒸发器，冷冻柜的前后端分别设有进料口和出料口，并于冷冻柜的底面安装有用于将鞋子从进料口输送至出料口的传送带；其特征在于：所述出料口的上侧设有暖风进口，出料口的下侧设有暖风出口，于主体机架上层设有第一风机和第二风机，该第一风机除用于冷却蒸发器外，还同时将冷却蒸发器所产生的暖风输送至暖风进口，第一风机连通暖风出口将出料口的暖风迅速吸走，从而在出料口位置形成快速流动的暖风墙；所述第一风机与暖风进口之间设置鼓风通道，所述第二风机与暖风出口之间设置吸风通道，所述鼓风通道上设有可分配风量大小的闸门，控制用于回温的风量的大小，从而控制回温温度，避免冷冻后鞋子回温过高或过低。
作为一种优选方案，所述闸门是活动式推板结构。
本发明与现有技术相比具有明显的优点和有益效果，具体而言，由上述技术方案可知，其主要是由于设置了第一风机、第二风机、暖风进口、暖风出口，该第一风机除用于冷却蒸发器外，还同时将冷却蒸发器所产生的暖风输送至暖风进口，第二风机连通暖风出口将出料口的暖风迅速吸走，在出料口位置形成快速流动的暖风墙，这样，利用上吹下吸的设计能增强对流，暖风从鞋子表面快速吹过，使经过冷冻柜降温后鞋子在下料之前迅速回温，加之强气流将水气随风排走，冷热交换过程中不会产生凝露，解决传统机器输出冷冻鞋子与空气接触产生凝露而无法直接包装和发霉问题；此外，在暖风进口和暖风出口之间没有任何阻隔，从而暖风从暖风进口吹入后瞬间被吸向暖风出口，形成快速直线流动，直通式的暖风在出料口自动形成隔离门作用，这样，出料口位置的热气流和冷冻柜内的冷气流没来得及交换，暖风便被吸走，将冷冻区域隔绝，解决传统设备会有部分暖风会冲入冷冻区域从而降低冷冻效果和加大能耗的问题。

请参照图1至图3所示，其显示出了本发明之较佳实施例的具体结构，是一种带回温的冷冻定型机，其结构包括主体机架10，该主体机架10分为上层、中层、下层，该中层设有用于定型鞋子的冷冻柜11，冷冻柜11的内部设有冷凝器（图未示），冷冻柜11的左右外侧设有蒸发器20，冷冻柜11的前后端分别设有进料口12和出料口13，并于冷冻柜11的底面安装有用于将鞋子从进料口12输送至出料口13的传送带14。运行时，将鞋子置放于进料口12，传送带14在电机拖动下缓慢地将鞋子送入冷冻柜11进行冷冻定型，再从出料口13送出。
此外，主体机架10的上层安装压缩机16、风机等制冷组件。本实施例中，风机至少有两台，分别是第一风机17和第二风机18，所述出料口13的上侧设有暖风进口131，出料口13的下侧设有暖风出口132。该第一风机17除用于冷却蒸发器20外，还同时将冷却蒸发器20所产生的暖风输送至暖风进口131，第二风机18连通暖风出口132将出料口13的暖风迅速吸走，这样，在出料口13位置形成暖风快速流动的暖风区域。由于鞋子经过冷冻柜11后温度降低，若直接输出接触外界大气，即刻会在鞋子表面凝结水珠，不但无法直接包装，而且潮湿的鞋子易发霉。藉此，本冷冻定型机在出料口13设置暖风区域，快速流动的暖风墙有效隔离外界空气，使出料口13充盈着暖风，藉由本方案利用上吹下吸的设计能增强对流，暖风从鞋子表面快速吹过，使经过冷冻柜降温后鞋子在下料之前迅速回温，加之强气流将水气随风排走，冷热交换过程中不会产生凝露，解决传统机器输出冷冻鞋子与空气接触产生凝露而无法直接包装和发霉问题。此外，由于在暖风进口131和暖风出口132之间没有任何阻隔，从而暖风从暖风进口131吹入后瞬间被吸向暖风出口132，形成快速直线流动，直通式的暖风在出料口13自动形成隔离门作用，这样，出料口13位置的热气流和冷冻柜11内的冷气流没来得及交换，暖风便被吸走，将冷冻区域隔绝，解决传统设备会有部分暖风会冲入冷冻区域从而降低冷冻效果和加大能耗的问题。
参照图2和图3，所述第一风机17与暖风进口131之间设置鼓风通道171，所述第二风机18与暖风出口132之间设置吸风通道181，该鼓风通道171与吸风通道181是软管，或者是采用隔离板在主体机架10内隔离出的通道，或者是其它能够实现送风的结构，在此亦不作限定。运行时，出料口13位置的暖风除了帮助鞋子回温，亦有部分会冲入冷冻区域降低冷冻效果和增加机器能耗，因此如图3所示，本实施例设计了以下结构：在所述鼓风通道171上设有可分配风量大小的闸门172，控制用于回温的风量的大小，从而控制回温温度，避免冷冻后鞋子回温过高或过低。本实施例中，该闸门172是活动式推板结构，闸门推动至不同的位置，可以分配排向出料口和外界两股风的风量大小，确保降温后鞋子在下料之前回温即可，多余的暖风排走。
还有，所述冷冻柜11的进料口12和出料口13设有可防止冷气泄漏的隔离带15或者电动门。以及，所述暖风进口131与暖风出口132之间形成的暖风区域与冷冻柜11内的冷风区域之间设有隔离带15或者电动门。该隔离带15或者电动门可以将冷空气与暖空气有效隔绝，避免冷暖空气交汇。为了保障隔离效果，此处的隔离带15设有两层，比单层隔离带15效果的隔绝效果更佳。
再有，该主体机架10上还设置有控制系统30，所述制冷装置的压缩机16、冷凝器、蒸发器20、传送带14的拖动电机以及各风机17、18均与控制系统30电连接，通过操作控制系统30面板的旋钮以及按键，可以调节冷冻柜11的温度，各风机17、18的风量，传送带14的传输速度等，并且，该控制系统30上最好设计报错系统，当出现过流、过压等机器故障时发出警报。
本发明之冷冻定型机的设计原理如下：
操作控制系统30面板上的电源开关，启动机器，运行压缩机16、冷凝器、蒸发器20、传送带14的拖动电机和各风机17、18。将鞋子置于传送带14上，在拖动电机的带动下，传送带14将鞋子缓慢从进料口12送入冷冻柜11，鞋子在冷冻柜11内降温定型，然后从出料口13送出。当鞋子经过进料口12和出料口13时，会将隔离带15挑起，鞋子离开后，隔离带15自动复位，有效防止冷冻柜11的冷气泄漏。鞋子送出至出料口13位置时，由于第一风机17将冷却蒸发器20时所产生的暖风直接回用，通过暖风进口131吹出从而形成一道暖风墙，第二风机18通过暖风出口132快速将出料口13位置的暖风吸走，从而冷冻定型后出来的鞋子经过在暖风区域，暖风墙吹向鞋子的表面使鞋子迅速回温，因此当鞋子下料后，接近于常温，即使接触外界空气，也不会在鞋子表面凝露，可直接包装，储藏过程中亦不会出现发霉变质的问题。
综上所述，本发明的设计重点在于，其主要是由于设置了第一风机17、第二风机18、暖风进口131、暖风出口132，该第一风机17除用于冷却蒸发器20外，还同时将冷却蒸发器20所产生的暖风输送至暖风进口131，第一风机17连通暖风出口132将出料口13的暖风迅速吸走，这样，在出料口13位置形成快速流动的暖风墙，有效隔离外界空气，使出料口13充盈着暖风，藉由本方案利用上吹下吸的设计能增强对流，暖风从鞋子表面快速吹过，使经过冷冻柜降温后鞋子在下料之前迅速回温，加之强气流将水气随风排走，冷热交换过程中不会产生凝露，解决传统机器输出冷冻鞋子与空气接触产生凝露而无法直接包装和发霉问题；此外，在暖风进口131和暖风出口132之间没有任何阻隔，从而暖风从暖风进口131吹入后瞬间被吸向暖风出口132，形成快速直线流动，直通式的暖风在出料口13自动形成隔离门作用，这样，出料口13位置的热气流和冷冻柜11内的冷气流没来得及交换，暖风便被吸走，将冷冻区域隔绝，解决传统设备会有部分暖风会冲入冷冻区域从而降低冷冻效果和加大能耗的问题。
以上所述，仅是本发明的较佳实施例而已，并非对本发明的技术范围作任何限制，故凡是依据本发明的技术实质对以上实施例所作的任何细微修改、等同变化与修饰，均仍属于本发明技术方案的范围内。
