Description

Technical Field

[0001] This utility model relates to the field of push knife technology, and in particular to a novel push knife holder assembly. Background Technology

[0002] In the field of tile processing, the performance of tile marking devices directly affects the marking accuracy and processing quality. Traditional tile marking devices have obvious defects in structural design and performance.

[0003] Regarding the locking structure, many existing devices employ a single-point locking method, which suffers from poor stability. During actual operation, the sliding shell is prone to shaking or displacement, which not only affects the operator's precise control of the device but also reduces the accuracy of scribing, making it difficult to meet the requirements of high-precision machining.

[0004] The pen-shaped cutter mounting structure also has shortcomings. Conventional pen-shaped cutters are mounted vertically with the flat side facing the top pressure handle. When the top pressure handle is not mounted vertically, the pen-shaped cutter and the crossbar cannot remain perpendicular. During the scribing process, the cutter's trajectory deviates, resulting in a significant decrease in scribing accuracy and an increased scrap rate.

[0005] Regarding the blade assembly, traditional devices lack effective height adjustment and positioning structures, resulting in axial clearance after installation. This causes the blade to easily shift during the marking process, making it difficult to guarantee the straightness of the lines. Furthermore, it cannot provide flexible and precise height adjustment based on different tile thicknesses, limiting the device's applicability. Utility Model Content

[0006] The purpose of this invention is to provide a novel pusher blade holder assembly to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution, which includes a crossbar, a sliding main housing movably mounted on the crossbar, an oblique mounting shell at the front end of the sliding main housing, symmetrical insertion holes at the top and bottom of the oblique mounting shell, a detachable pen-shaped knife inserted between the two insertion holes, a first pressing handle threaded on the front of the oblique mounting shell, the pen-shaped knife being fixed to the oblique mounting shell by the first pressing handle, and a mounting plate at the bottom of the sliding main housing, on which a detachable large knife assembly is mounted.

[0008] As a preferred embodiment of this utility model, a second pressing handle is threaded on the back of the sliding main housing, and a pressure plate is threaded onto the top of the second pressing handle via a snap ring, the pressure plate pressing onto the crossbar.

[0009] As a preferred embodiment of this utility model, the mounting plate is provided with a pair of through slots, and the mounting plate is also provided with several toothed grooves. A third pressing handle is threaded on one side of the mounting plate, and a protective abutment is sandwiched between the third pressing handle and the mounting plate.

[0010] As a preferred embodiment of this utility model, the large knife assembly includes a pair of L-shaped clamping blocks. The large knife body is fixed between the two L-shaped clamping blocks by bolt two. The L-shaped clamping blocks are fixed to the mounting plate by bolt three passing through the through groove. The back of the L-shaped clamping blocks is provided with several corresponding teeth with interlocking grooves. The interlocking teeth are arranged in the tooth grooves.

[0011] As a preferred embodiment of this utility model, a scale is provided at the top of the crossbar, and a scale marking plate is fixed to one side of the top of the sliding main housing by a bolt, with one side of the scale marking plate attached to the scale.

[0012] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0013] 1. This utility model adopts a pressure plate structure with protruding ends to fully contact the crossbar, greatly increasing the contact area. The second top-pressing handle passes through the pressure plate and is blocked by a snap ring to prevent it from falling off. This design changes the fixing between the sliding main housing and the crossbar from point contact to surface contact, which not only significantly enhances the stability of the device and effectively avoids shaking or displacement of the sliding main housing during operation, but also makes the operation of adjusting the position of the sliding main housing simpler and more precise, providing a stable foundation for subsequent marking operations.

[0014] 2. This utility model optimizes the installation structure of the pen-shaped knife. The pen-shaped knife is installed at an angle, and its shoulder is in full contact with the stretching and forming surface of the knife holder. The first top-pressing handle presses on the arc surface of the pen-shaped knife. With this design, no matter what angle the first top-pressing handle is at, as long as it is locked, it can ensure that the pen-shaped knife is perpendicular to the crossbar. This not only simplifies the installation process and reduces the installation difficulty, but also greatly improves the stability of the pen-shaped knife installation, providing a strong guarantee for accurate line drawing.

[0015] 3. The blade assembly of this utility model is connected to the mounting plate via an L-shaped clamp. The interlocking teeth on the L-shaped clamp perfectly engage with the toothed grooves on the mounting plate. This design not only allows for precise adjustment of the blade's height to meet the marking requirements of tiles of different thicknesses, but also ensures parallelism with the crossbar because both the toothed grooves and interlocking teeth are produced using a stretching forming process. Furthermore, the blade has no axial clearance after installation, further improving the stability and reliability of the blade installation and laying a solid foundation for achieving high-precision marking.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0028] like Figures 1-10As shown, the present invention proposes a novel push knife holder assembly, which includes a crossbar 1 and a sliding main housing 2 movably disposed on the crossbar 1. The sliding main housing 2 can slide freely along the length direction of the crossbar 1, which provides a moving carrier for the device to perform the marking operation. At the front end of the sliding main housing 2, an inclined mounting shell 20 is installed at an angle. This design allows the pen-shaped knife 6 to contact the tile surface at a suitable angle during operation, ensuring the marking effect.

[0029] The inclined mounting shell 20 has symmetrical insertion holes 21 on its top and bottom. The pen-shaped blade 6 can pass through the two insertion holes 21 for installation. To fix the pen-shaped blade 6 on the inclined mounting shell 20, the first top pressure handle 22 is screwed into the front of the inclined mounting shell 20 by thread. When the first top pressure handle 22 is tightened, the pressure generated by it acts on the pen-shaped blade 6, thereby firmly fixing the pen-shaped blade 6 and preventing shaking or displacement during the drawing process.

[0030] To prevent the sliding main housing 2 from sliding when it does not need to move, a second pressing handle 23 is screwed into the top of the sliding main housing 2 by means of a snap ring 24. The top of the second pressing handle 23 is connected to the pressure plate 25 by means of a snap ring 24. The snap ring 24 ensures that the pressure plate 25 is stably connected to the second pressing handle 23. When the second pressing handle 23 is tightened, the pressure plate 25 will press down on the crossbar 1. By increasing the friction, the sliding main housing 2 is fixed at a specific position on the crossbar 1.

[0031] The bottom of the sliding main housing 2 is fixed with a mounting plate 3 to provide an installation position for the blade assembly 5. The mounting plate 3 has a pair of through slots 31 and several toothed grooves 30. The blade assembly 5 consists of a pair of L-shaped clamping blocks 50 and a blade body 51. The blade body 51 is fixed between the two L-shaped clamping blocks 50 by bolt 2 53. During installation, the L-shaped clamping blocks 50 pass through the through slots 31 by bolt 3 54 to install the blade assembly 5 on the mounting plate 3. Several interlocking teeth 52 are provided on the back of the L-shaped clamping blocks 50. These interlocking teeth 52 correspond to the toothed grooves 30 on the mounting plate 3 and can be embedded in the toothed grooves 30. By selecting different positions of the toothed grooves 30 to embed the interlocking teeth 52, the height of the blade assembly 5 can be adjusted to meet different marking requirements.

[0032] On one side of the mounting plate 3, the third top-pressure handle 32 is screwed in by thread. A protective abutment 33 is sandwiched between the third top-pressure handle 32 and the mounting plate 3. When it is necessary to fine-tune or fix the parts on the mounting plate 3, the third top-pressure handle 32 is turned. The protective abutment 33 can prevent the cutter head from hitting the edge of the tile when the cutter head is scribbling. At the same time as the cutter head is cutting, the protective abutment 33 touches the tile surface, so the cutter head will not hit the workbench.

[0033] To achieve precise control over the marking position, a scale 10 is installed at the top of the crossbar 1. A scale marking plate 4 is fixed to one side of the top of the sliding main housing 2 by bolt 40. One side of the scale marking plate 4 is tightly attached to the scale 10. During the movement of the sliding main housing 2, the operator can accurately judge the moving distance of the sliding main housing 2 by the position of the scale marking plate 4 on the scale 10, thereby achieving accurate control over the marking position of the tile.

[0034] First, insert the pen-shaped blade 6 into the corresponding socket 21 of the device. Carefully adjust the height of the pen-shaped blade 6 according to the thickness of the tile and the actual marking requirements. Then, tighten the first top-pressure handle 22 clockwise to firmly fix the pen-shaped blade 6 using the top-pressure principle, preventing it from shifting during the marking process. Next, place the device with the pen-shaped blade 6 installed on it stably above the tile to be processed with the help of the support components, ensuring that the device is in a horizontal state to avoid marking deviation due to tilting of the device. Finally, push the sliding main housing 2 with both hands to make the device move forward at a constant speed. During this process, the pen-shaped blade 6 will make precise markings on the tile surface. During the pushing process, it is necessary to maintain a uniform force to ensure the continuity and accuracy of the marking.

[0035] When it is necessary to use the large blade for marking, remove the installed pen-shaped blade 6 from the insertion hole 21. Then, place the large blade assembly 5 in front of the mounting plate 3 and insert the two bolts 54 into the two through slots 31 respectively. Next, the large blade assembly 5 is equipped with bite teeth 52 of different heights. According to the thickness of the tile and the marking requirements, select the bite teeth 52 of appropriate height, align them with the tooth grooves 30 and insert them. After confirming that the bite teeth 52 are inserted in place, tighten the two bolts 53 to firmly fix the large blade assembly 5. Finally, referring to the marking operation of the pen-shaped blade 6, place the device above the tile and push the sliding main housing 2 to use the large blade to mark the tile surface. During the pushing process, it is also necessary to maintain a stable speed and force to achieve a high-quality marking effect.
