Description

Technical Field

[0001] The utility model relates to the technical field of disposable slippers, in particular to a temporary storage structure for slipper sole fabrics. Background Art

[0002] Disposable slippers are mainly used in hotels, beauty salons, dust-free workshops, etc. because of their low price, convenience, and sanitation. Disposable slippers are mainly composed of a sole and an upper. At present, the production of disposable slippers has developed from traditional manual and semi-automatic to automated production. The automated production equipment of disposable slippers is also in a continuous development process. In the production process of existing disposable slippers, the sole fabric is generally processed, and then it is combined with the processed upper on the other side and welded or bonded to complete the overall processing of the slippers.

[0003] For example, the Chinese utility model patent "A non-woven disposable slipper machine" with application number 202121596184.4 (authorization announcement number CN214904262U) discloses a similar automated production equipment, which includes a feeding unit and a textile unit head, wherein the feeding unit is arranged at one end of the textile unit, and a crawler conveyor unit is arranged inside the textile unit, a finished product carrier is arranged above the crawler conveyor unit, and the finished product carrier is combined and connected with the crawler conveyor unit, an upper weaving frame is arranged above the feeding unit, and a lower weaving frame is arranged on one side of the upper weaving frame, non-woven fabrics are arranged on the outer sides of the upper weaving frame and the lower weaving frame, and the non-woven fabrics are rotatably connected to the upper weaving frame and the lower weaving frame, an ironing module is arranged below the non-woven fabric, and the ironing module is connected to the feeding unit through a bracket.

[0004] However, when the sole fabric in this type of equipment is being processed, the fabric must be in a static state, which means that the fabric cannot be conveyed continuously, but in an intermittent feeding mode, which also requires the feeding to be in an intermittent transmission mode. This will lead to a problem: the feeding speed and the material use speed of the sole fabric are difficult to keep consistent, and synchronous transmission cannot be achieved, so that there is no way to form a good connection between the two, and there is no buffer space, which affects the processing quality and efficiency.

[0005] Therefore, how to provide a temporary storage space that can buffer between the feeding and the use of the sole fabric, so that the feeding and the use can be better connected, and at the same time, the sole fabric can always be kept in a taut state, is a problem that technical personnel in this field need to solve urgently. Utility Model Content

[0028] Figure 5 for Figure 2 A magnified schematic diagram of part A in FIG. DETAILED DESCRIPTION

[0029] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0030] like Figures 1 to 5 The temporary storage structure of the slipper sole fabric in this embodiment mainly includes a frame 1, a feeding roller 2, a feeding roller 2, a storage roller 4 and a feeding control mechanism 5, etc.

[0031] refer to Figures 1 to 4As shown, the feeding roller 2 is arranged on the frame 1, and is mainly used to assist the feeding of the sole fabric A. The material roller 3 is arranged on the frame 1, and is mainly used to assist the discharging of the sole fabric A for subsequent material needs. The storage roller 4 can be movably arranged on the frame 1, and the storage roller 4 is located between the feeding roller 2 and the material roller 3. It can rise or fall relative to the feeding roller 2, and in the process of rising or falling, it moves away from the feeding roller 2 to form a gap 4a between the two. The space formed by the gap 4a can temporarily store the sole fabric A conveyed from the feeding roller 2. The feeding control mechanism 5 can drive the sole fabric A to move forward. The feeding control mechanism 5 can stop feeding when the gap 4a between the storage roller 4 and the feeding roller 2 reaches a set distance, and restart feeding when the gap 4a between the storage roller 4 and the feeding roller 2 is lower than the set distance.

[0032] In order to optimize the structure and layout of the temporary storage space so that the distance 4a between the feeding roller 2 and the storage roller 4 can be better formed, in this embodiment, reference Figure 3 and Figure 4 As shown, the storage drum 4 is located below the feeding drum 2 and the material drum 3. The sole fabric A is transported downward from the feeding drum 2 to the storage drum 4, and then transported upward to the material drum 3 for discharge. During the operation of the equipment, when the feeding drum 2 is in a normal feeding state, the storage drum 4 descends under the action of its own gravity, so that the distance 4a between the storage drum 4 and the feeding drum 2 is gradually enlarged, and can be used for temporary storage of the sole fabric A; when the material drum 3 is in a normal discharging state, the storage drum 4 can rise driven by the sole fabric A in the discharging state, so that the distance 4a between the storage drum 4 and the feeding drum 2 is gradually reduced.

[0033] It is necessary to explain here that by continuously enlarging or reducing the spacing 4a, the equipment can automatically adjust the size of the temporary storage space at any time according to the needs of feeding and using materials, so that a buffer zone can be formed between the feeding and using materials of the sole fabric A, thereby making the feeding and using materials of the sole fabric A better connected. In addition, since the storage drum 4 always has the power to pull the sole fabric A downward under the action of its own gravity during the process of lifting and lowering, it can ensure that the sole fabric A is always in a tight state during the transportation process, which improves the subsequent processing quality and processing efficiency to a certain extent.

[0034] Secondly, in order to better convey the sole material A to the feeding roller, refer to Figure 1As shown, in this embodiment, the feeding control mechanism 5 includes a motor 5a and a transmission component 5b, the motor 5a is drivingly connected to the transmission component 5b, and the sole fabric A passes through the transmission component 5b and is driven by the motor 5a to be conveyed to the feeding roller 2. In order to optimize the overall structure of the transmission component 5b and make it more convenient to feed, the transmission component 5b here includes a driving roller 5b1 and a driven roller 5b2, the driving roller 5b1 and the driven roller 5b2 are driven and connected together by setting a mutually meshing gear 5b3, the driving roller 5b1 is also provided with a driven wheel 5b4, the motor 5a is provided with a driving wheel 5b5, and the driving wheel 5b5 and the driven wheel 5b4 are driven and connected together by setting a transmission belt 5b6.

[0035] At the same time, in order to timely and accurately control the up and down movement of the storage drum 4, refer to Figure 4 As shown in the figure, in the present embodiment, the feeding control mechanism 5 also includes a travel switch 5c electrically connected to the motor 5a, and the travel switches 5c are provided above and below the storage drum 4. When the storage drum 4 descends to the set position, the storage drum 4 touches the travel switch 5c below to stop the motor 5a from feeding. When the storage drum 4 rises to the set position, the storage drum 4 touches the travel switch 5c above to restart the motor 5a from feeding.

[0036] In addition, in order to make the up and down lifting of the storage drum 4 more stable and smooth, refer to Figure 2 and Figure 5 As shown, in the present embodiment, a guide mechanism 6 is provided between the storage drum 4 and the frame 1 for guiding the storage drum 4 when it is lifted up and down. The guide mechanism 6 here includes two guide blocks 6a. The two ends of the storage drum 4 are rotatably provided on the two guide blocks 6a respectively. Two guide grooves 1a which are oppositely arranged and can be adapted to the corresponding guide blocks 6a are also formed on the frame 1. When the storage drum 4 is in the state of being lifted up and down, the two opposite side surfaces of the guide blocks 6a can fit on the corresponding side walls of the guide groove 1a and slide up and down.

[0037] In addition, in order to optimize the overall structure and layout of the guide groove 1a so that it can be better formed on the frame 1, in the present embodiment, two columns 1b are arranged at intervals on opposite sides of the frame 1, and the interval between the two columns 1b forms the guide groove 1a. The two guide blocks 6a are formed with oppositely arranged limiting portions 6a1. When the guide blocks 6a are in the state of sliding up and down, the two limiting portions 6a1 can both resist the outer side surfaces of the corresponding columns 1b to limit the horizontal deviation of the storage drum 4.

[0038] In this embodiment, in order to ensure that both ends of the storage drum 4 are always at the same level, Figure 2As shown, a balancing mechanism 7 for stabilizing the up and down movement of the storage drum 4 is specially provided on the frame 1. The balancing mechanism 7 includes two sprocket groups 7a which are provided on the frame 1 and spaced apart from each other. Each sprocket group 7a includes a rotating shaft 7a1 and two sprockets 7a2 provided at both ends of the rotating shaft 7a1. The upper and lower sprocket groups 7a are driven and connected together by two chains 7a3, and the two chains 7a3 are respectively connected to their corresponding guide blocks 6a.

[0039] In this embodiment, in order to better feed the sole material A, refer to Figure 1 and Figure 2 As shown, the feeding roller 2 is arranged at a high position of the frame 1, and the conveying assembly 5b is arranged at a bottom position of the frame 1. The sole fabric A is conveyed from bottom to top in an inclined state toward the feeding roller 2 driven by the conveying assembly 5b.

[0040] The working principle of the temporary storage structure for the sole fabric of slippers in this embodiment is described as follows:

[0041] When the sole fabric A in the temporary storage space is gradually used up, the storage drum 4 has been synchronously lifted up under the pull of the sole fabric A in the discharging state (the pulling power source here mainly comes from the power generated by the operation of the rear-end material-using process, which is not described in detail here). When the storage drum 4 hits the travel switch 5c located above, the motor 5a will start the feeding work to gradually output the sole fabric A. At the same time, the storage drum 4 will synchronously drop under the action of its own gravity and start to store the sole fabric A. When the storage drum 4 hits the travel switch 5c located below, the motor 5a will stop the feeding work until the sole fabric A in the storage space is used up again. Only then can the above actions be repeated, so that the up and down lifting of the storage drum 4 forms a cycle.

[0042] It should be noted that in the description of this embodiment, the terms "front, rear", "left, right", "up, down", etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
