Abstract
Description
Technical Field
[0001] The utility model belongs to the field of manual tile cutting machines, in particular to a manual tile cutting machine adopting a combined sliding block. Background Art
[0002] The structure of the existing manual tile cutting machine mainly includes a handle, a bottom plate, a guide rail, a slider and a cutter wheel. The guide rail has a square cross section. The guide rail is arranged parallel to the bottom plate through a bracket. The slider is slidably arranged on the guide rail. The guide rail passes horizontally through the slider. The handle is hinged on the upper part of the slider. The rear end of the handle is a hand-held part, which is located above the guide rail. The front end of the handle is located below the guide rail and is provided with a rotatably connected cutter wheel. When in use, the tile is placed on the bottom plate, the hand-held part of the handle is pressed down, so that the cutter wheel contacts the tile, and the handle is pushed. The handle moves along the guide rail through the slider, driving the guide wheel to move along the tile, marking and cutting the tile.
[0003] In the existing manual tile cutting machines, the slider is an integral structure, and the guide rail is usually made of flat steel. In order to eliminate the unevenness and bending of the flat steel surface, the flat steel needs to be ground on all four sides. However, due to the influence of the processing accuracy, the final guide rail will have errors of several tens of wires in height and width. In order to reduce the movement resistance of the slider and ensure the marking accuracy, bearings connected to the slider are set on all four sides of the guide rail, and a spring is set between the bearing and the slider. The spring gives pressure to the bearing to move inward so that the bearing and the guide rail fit.
[0004] In the existing manual tile cutters, since the slider is an integral structure, and a large number of parts need to be installed in the slider, and the inner structure of the slider is complex, the mold for making the slider is complex, with many complex core-pulling mechanisms, the mold price is high, and injection molding defects are prone to occur on the slider, so that the finished product yield of the slider is low, resulting in a high production cost of the manual tile cutter; four springs need to be installed on each slider, and the large number of springs installed not only further makes it difficult to reduce the production cost, but also leads to a slow assembly speed, that is, the production efficiency of the manual tile cutter is low.

At the same time, it is easy to assemble and can improve the production efficiency of the manual tile cutter. Therefore, the utility model has the advantages of low production cost and high production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The slide block is composed of a first side block 2 and a second side block 3, and the guide rail 1 passes between the first side block 2 and the second side block 3. The first side block 2 is connected to the second side block 3 by four fasteners 14 composed of bolts and nuts.
[0028] A first side cavity 4 is provided on the inner side of the first side block 2, and two vertical first rotating shafts 11 are provided in the first side cavity 4. The two first rotating shafts 11 are respectively close to the front and rear ends of the first side block 2. Two first bearings 5 are provided on the first rotating shaft 11. The two first bearings 5 are respectively close to the upper and lower sides of the guide rail 1, and the two first bearings 5 are respectively close to the two ends of the first rotating shaft 11. A plate-shaped spring 8 is provided between the two first rotating shafts 11. The middle part of the spring 8 is screwed to the first side block 2, and the two ends of the spring 8 are elastically connected to the middle parts of the two first rotating shafts 11 respectively. Guide blocks 12 are provided at both ends of the first rotating shaft 11, and the guide blocks 12 are plugged into the rotating shaft 11. A guide groove 21 is provided on the first side block 2, and the guide block 12 is located in the guide groove 21 and maintains a sliding connection with the first side block 2.
[0029] A second side cavity 6 is provided on the inner side of the second side block 3, two vertical second rotating shafts 13 are provided in the second side cavity 6, four ribs 19 are provided in the second side cavity 6, all of which are connected to the second side block 3, one second rotating shaft 13 is fixed to every two ribs 19, and a slot 20 is provided on the rib 19 to be radially clamped by the second rotating shaft 13, and the second rotating shaft 13 is tightly clamped in the slot 20. The two second rotating shafts 13 are respectively close to the front and rear ends of the second side block 3, and both ends of the second rotating shaft 13 are connected to the second side block 3. Two second bearings 7 are provided on the second rotating shaft 13, and the two second bearings 7 are respectively close to the two ends of the second rotating shaft 13, and the two second bearings 7 are respectively close to the upper and lower sides of the guide rail 1.
[0030] Two horizontal third rotating shafts 17 are provided between the first side block 2 and the second side block 3 . The two third rotating shafts 17 are respectively close to the front and rear ends of the slider. The third rotating shafts 17 are located below the guide rail 1 . Two third bearings 9 are provided on the third rotating shafts 17 .
[0031] Two horizontal fourth rotating shafts 18 are provided between the first side block 2 and the second side block 3 . The two fourth rotating shafts 18 are respectively close to the front and rear ends of the slider. The fourth rotating shafts 18 are located above the guide rail 1 .

[0034] Manual tile cutting machine, such as Figure 3 As shown, the guide rail 1 has several tens of degrees of error in height and width. The spring 8 squeezes the first rotating shaft 11 inward, so that the first bearing 5 presses the guide rail 1. At the same time, the guide rail 1 is driven by the first bearing 5 to fit with the second bearing 7. The slider is fixed in the width-up position of the guide rail 1 to ensure that the cutting line is straight when cutting tiles and the cutting quality is good. The slider still has a certain amount of upper and lower margins in the height direction of the guide rail, but because the handle 15 is always pressed downward when marking and breaking tiles, the guide rail 1 is always in contact with the fourth bearing 10 under the reaction force of the tiles. The position of the slider in the height direction of the guide rail 1 is also fixed when marking and breaking tiles, which does not affect the operation.
[0035] The utility model improves the slider on the basis of the existing manual tile cutter. The use of the improved slider can reduce the production cost of the manual tile cutter and improve the production efficiency. The improved slider is also conducive to the subsequent use of automated equipment to realize automated batch assembly, thereby further improving the production efficiency.
