Description

Technical Field

[0001] The utility model relates to a processing device for rain boots, in particular to a grinding device for the rain boot cylinder. Background Art

[0002] Rain boots are used for daily water isolation and also as labor protection shoes in special environments. For some occasions, due to the limited height of the boot cylinder, a single rain boot cannot achieve effective protection and needs to be used together with waterproof pants or one-piece diving pants, etc. When in use, it is necessary to ensure a sealed connection between the trouser legs and the upper edge of the rain boot cylinder. Generally, glue bonding or thermoplastic welding is used for the connection. However, due to the relatively smooth surface of the rain boots and the difficulty in connecting the rain boot cylinders of different materials with the waterproof pants, after glue bonding or thermoplastic welding, the connection part is prone to de-bonding or separation, and its sealing performance cannot be guaranteed after long-term use. In order to make the connection between the rain boots and the rain pants firm and the sealing performance durable, the outer side of the upper edge of the rain boot cylinder can be ground before connection. After grinding, the smooth layer on the surface is removed to make its surface rough, and then the connection is made, which can greatly improve the firmness, sealing performance and durability of the connection.

[0003] However, there is no special grinding device for rain boot cylinders at present. The grinding devices in the current shoe processing field are generally used for grinding shoe soles. Therefore, when grinding the rain boot cylinders, only manual hand-held electric grinders can be used for grinding operations, which are inefficient and have certain risks.

Specific embodiments

[0028] The embodiments of the present utility model will be described below with reference to the accompanying drawings.

[0029] Embodiment 1

[0030] As Figure 1 , Figure 2 and Figure 3 shown, Embodiment 1 of the present utility model is a rain boot barrel grinding device, and its structure mainly includes a frame 1, an adjustment module 2, a grinding machine 5, a rain boot fixing mold 3, a rotation drive module 4, etc.

[0031] Among them, the rain boot fixing mold 3 is frustum-shaped, the axis of the rain boot fixing mold 3 is in a horizontal state, the rain boot fixing mold 3 is directly or indirectly connected to the frame 1, and the rain boot fixing mold 3 needs to be able to rotate around its own axis. The frustum-shaped rain boot fixing mold 3 is large at one end and small at the other end, and the large end of the rain boot fixing mold 3 is connected to the rotation drive module 4, and the rotation drive module 4 drives the rain boot fixing mold 3 to rotate.

[0032] On the one hand, the frustum-shaped rain boot fixing mold 3 is convenient for the sleeving of the rain boot barrel, and the barrel can be sleeved on the rain boot fixing mold 3 from the small end of the rain boot fixing mold 3. On the other hand, more importantly, it can fix rain boot barrels of different sizes. For rain boots of different sizes, the circumferences of the ports of their barrels are different. On the frustum-shaped rain boot fixing mold 3, between its two ends, the circumferences of the surface circles change within a certain range, and it can be applicable to rain boots within a certain size range. The size of the rain boot fixing mold 3 can be made according to needs.

[0033] The grinding machine 5 is installed on the adjustment module 2. The position of the grinding machine 5 is adjusted through the adjustment module 2. A grinding head 6 is provided on the lower end rotating shaft 4-2 of the grinding machine 5. Among them, the adjustment module 2 can include movements in three directions of X, Y, and Z, enabling the grinding head 6 to move in three directions for grinding processing. For the convenience of processing and to simplify the structure of the device, the grinding head 6 is located directly above the rain boot fixing mold 3. In this way, the grinding head 6 does not need to adjust the front-back direction and only needs to move left-right and up-down to contact the characteristic position on the surface of the rain boot barrel located on the rain boot fixing mold 3 to complete the grinding operation.

[0034] Since the taper on the surface of the rain boot fixing mold 3 is small, the grinding machine 5 can be in a vertical state. Although this will form a certain angle between the grinding head 6 and the surface of the rain boot fixing mold 3, because the angle is very small, it will not affect the grinding quality. It is also possible to have a certain angle between the up-down movement direction of the adjustment module 2 and the vertical direction, so that the lower end face of the grinding head 6 is parallel to the surface of the rain boot fixing mold 3. Or the grinding machine 5 can be installed obliquely on the adjustment module 2, the axis of the grinding head 6 is perpendicular to the surface of the rain boot fixing mold 3, and the grinding machine 5 still moves up and down along the vertical direction, but the lower end face of the grinding head 6 remains parallel to the surface of the rain boot fixing mold 3.

[0035] The adjustment module 2 specifically includes an X-axis movement mechanism 2-1 and a Z-axis movement mechanism 2-2. The X-axis movement mechanism 2-1 is arranged on the frame 1, and the Z-axis movement mechanism 2-2 is driven by the X-axis movement mechanism 2-1 to move horizontally. The grinding machine 5 is installed on the Z-axis movement mechanism 2-2 and is driven by the Z-axis movement mechanism 2-2 to move up and down.

[0036] Among them, the X-axis movement mechanism 2-1 includes a first frame body 2-1-1, a first lead screw 2-1-2, a first guide rail 2-1-3, and a first slider 2-1-5. The first frame body 2-1-1 is arranged on the frame 1. The first lead screw 2-1-2 and the first guide rail 2-1-3 are installed parallel to each other on the first frame body 2-1-1. The first slider 2-1-5 is installed on the first lead screw 2-1-2 and the first guide rail 2-1-3. A first handwheel 2-1-4 is provided at the end of the first lead screw 2-1-2. By driving the first lead screw 2-1-2 to rotate through the first handwheel 2-1-4, the position of the first slider 2-1-5 is adjusted. The operator adjusts the position of the first slider 2-1-5 through the first handwheel 2-1-4, thereby adjusting the position of the grinding machine 5 in the axial direction of the rain boot fixing mold 3.

[0037] The Z-axis moving mechanism 2-2 includes a second frame body 2-2-1, a second lead screw 2-2-2, a second guide rail 2-2-3 and a second slider 2-2-5. The second frame body 2-2-1 is arranged on the first slider 2-1-5. The second lead screw 2-2-2 and the second guide rail 2-2-3 are installed in parallel on the second frame body 2-2-1. The second slider 2-2-5 is installed on the second lead screw 2-2-2 and the second guide rail 2-2-3. A second handwheel 2-2-4 is arranged at the end of the second lead screw 2-2-2. By driving the second lead screw 2-2-2 to rotate with the second handwheel 2-2-4, the position of the second slider 2-2-5 is adjusted. The second slider 2-2-5 is used to install the grinding machine 5. The operator adjusts the distance between the grinding head 6 at the lower end of the grinding machine 5 and the surface of the rain shoe fixing mold 3 through the second handwheel 2-2-4.

[0038] Due to the self-locking function of the lead screw, after the grinding head 6 is adjusted to the corresponding position, even if the grinding head 6 is subjected to an external force, its position will not change. Only when the operator rotates the first handwheel 2-1-4 and the second handwheel 2-2-4 can the position of the grinding head 6 be adjusted.

[0039] During the grinding process, the rain shoe fixing mold 3 will be subjected to a downward pressure. Therefore, a corner support pipe 7 is provided on the frame 1. The lower part of the corner support pipe 7 is connected to the frame 1. The upper part of the corner support pipe 7 is in a horizontal state and is rotatably connected to the large end of the rain shoe fixing mold 3. The rain shoe fixing mold 3 is supported by the corner support pipe 7.

[0040] The rotation drive module 4 includes a rotation drive element 4-1. The rotation drive element 4-1 is installed on the frame body to the right of the corner support pipe 7. The main shaft of the rotation drive element 4-1 is connected to the rain shoe fixing mold 3 through a rotating shaft 4-2. The rotating shaft 4-2 is coaxial with the rain shoe fixing mold 3. The rotating shaft 4-2 passes through the through hole on the side wall of the corner support pipe 7 and extends into the inner cavity of the upper part of the corner support pipe 7 to the inside of the rain shoe fixing mold 3. The power of the rotation drive element 4-1 is transmitted to the rain shoe fixing mold 3 through the rotating shaft 4-2, driving the rain shoe fixing mold 3 to rotate around its own axis.

[0041] Among them, the main shaft of the rotation drive element 4-1 and the rotating shaft 4-2 are connected through a coupling. Preferably, the coupling is a flexible coupling.

[0042] As Figure 3 shown, a support pipe 7-1 is provided at the front end of the upper part of the corner support pipe 7. The support pipe 7-1 can be an extension pipe welded to the front end of the upper part of the corner support pipe 7, or an extension part integral with the corner support pipe 7. A bearing 9 is sleeved on the support pipe 7-1. The rain shoe fixing mold 3 is connected to the support pipe 7-1 through the bearing 9. The rotating shaft 4-2 passes through the support pipe 7-1 and is connected to the connecting part 3-2 inside the rain shoe fixing mold 3.

[0043] Specifically, a support portion 3-1 and a connection portion 3-2 are fixed on the inner wall of the rain shoe fixing die 3. The support portion 3-1 is installed on the bearing 9, and the downward pressure received by the rain shoe fixing die 3 is transmitted through the support portion 3-1, the bearing 9, and the support pipe 7-1. The center of the connection portion 3-2 is connected to the rotating shaft 4-2. When the rotating shaft 4-2 rotates, it drives the connection portion 3-2 and the entire rain shoe fixing die 3 to rotate on the bearing 9.

[0044] Among them, the support portion 3-1 and the connection portion 3-2 can be plate-like structures or structures of other shapes.

[0045] A baffle 7-2 is provided on the support pipe 7-1. The baffle 7-2 is located inside the rain shoe fixing die 3 and is used to limit the position of the bearing and provide a certain degree of shielding for the large-end port of the rain shoe fixing die 3.

[0046] At the same time, a protective cover (not shown in the figure) is provided above the support pipe 7-1, and the protective cover shields and protects the rotating shaft.

[0047] Among them, the rotation driving element 4-1 is a reduction motor.

[0048] The frame 1 includes a main body frame 1-1, a vertical frame 1-2, and a horizontal frame 1-3. The vertical frame 1-2 is located in the middle above the main body frame 1-1. The adjustment module 2 is installed on the upper part of the vertical frame 1-2. The vertical frame 1-2 is located at a certain distance in front of the rear end of the main body frame 1-1. At the same time, the upper cross beam on the left side of the main body frame 1-1 is removed, so that when the rain shoe rotates, interference between the rain shoe and the frame 1 can be avoided. The horizontal frame 1-3 is located on the right part of the main body frame 1-1 and is connected to the right end of the main body frame 1-1. The rotation driving module 4 and the corner support pipe 7 are located on the horizontal frame 1-3.

[0049] In addition, adjustment legs 8 are provided at the four corners of the frame 1. The levelness of the entire frame 1 can be adjusted through the adjustment legs 8.
