Description

Technical Field

[0001] The utility model relates to the technical field of plate processing, in particular to a flexible flat scraping tool, a flexible flat scraping mechanism and an edge banding machine. Background Art

[0002] With the development and progress of society, panel-type custom furniture has been widely used. Edge banding is an important link in the production process of panel furniture. Edge banding can greatly improve the appearance quality of furniture, avoid damage to corners and edges during transportation and use, and prevent the veneer layer from being lifted or peeled off. It can also play a role in waterproofing, sealing the release of harmful gases and reducing deformation. Therefore, the quality of edge banding directly affects the appearance and service life of the product.

[0003] At present, edge banding machines are widely used to band the edges of boards. Edge banding machines are machines that automate the edge banding process and can replace manual work to bond the edge banding tape to the side of the board. After the edge banding is completed, since the edge banding tape and the board are bonded and fixed, it is easy for excess glue lines to remain. In order to ensure the flatness and cleanliness of the board after edge banding, the upper and lower surfaces of the board must be scraped flat; usually, a scraping mechanism is integrated on the edge banding machine to realize the automation of this process.

[0004] The posture or angle of the scraper of the existing flat scraping mechanism is usually not adjustable during the working process, which means that it can only be used to scrape the flat edges of straight plates. When the surface of the processed plate is uneven or the plate is tilted, the scraper cannot be adaptively adjusted in real time, making it difficult for the scraper of the flat scraping mechanism to maintain continuous contact with the plate, causing the scraper to scratch the surface of the plate or fail to scrape off the raised residual glue line. Utility Model Content

DETAILED DESCRIPTION

[0035] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0036] refer to Figure 1-Figure 10 The embodiments of the utility model provide a flexible flat scraping tool, a flexible flat scraping mechanism and an edge banding machine.

[0037] The flexible flat scraping tool 10 of the utility model embodiment includes a tool base 11, a guide seat 12 and a scraper 13 installed on the guide seat 12, the guide seat 12 and the tool base 11 are rotatably connected through a rotating shaft 14, and the bottom of the guide seat 12 faces the top of the tool base 11, and a guide surface 121 is provided on the top of the guide seat 12; wherein a reset spring 15 is provided between the guide seat 12 and the tool base 11, so that the guide seat 12 can rotate to a reset state relative to the tool base 11, and when the guide seat 12 is in the reset state, one end of the guide seat 12 presses against the top of the tool base 11, and the other end is tilted relative to the top of the tool base 11.

[0038] In the flexible flat scraping tool 10 of the utility model embodiment, by rotatably connecting the guide seat 12 with the tool base 11, and by arranging a return spring 15 between the guide seat 12 and the tool base 11, the guide seat 12 can swing back and forth around the axis of the rotating shaft 14, referring to Figure 3 Therefore, during the processing, the guide seat 12 can be adaptively adjusted in real time in the front-rear direction, thereby driving the scraper 13 to be adaptively adjusted in real time in the front-rear direction.

[0039] Specifically, in order to allow the guide seat 12 to float up and down relative to the tool base 11, a certain movable space should be reserved between the guide seat 12 and the tool base 11. For example, when the guide seat 12 is in a horizontal state, a certain gap is reserved between the guide seat 12 and the tool base 11.

[0040] Specifically, the blade 131 of the scraper 13 is flush with the guide surface 121. However, due to the size error or assembly error of the scraper 13, the blade 131 may not be flush with the guide surface 121.

[0041] In order to solve the above problems, the flexible flat scraper tool 10 in the embodiment of the utility model also includes a scraper seat 16, and the scraper 13 is fixed on the scraper seat 16; the scraper seat 16 is provided with a waist groove 122, and the guide seat 12 is provided with a threaded hole. The scraper seat 16 is fixed to the guide seat 12 by a bolt 161, and the bolt 161 passes through the waist groove 122 and is connected to the threaded hole.

[0042] Among them, the function of the bolt 161 is to fix the scraper seat 16 and the guide seat 12, and the waist groove 122 is set to be able to adjust the position of the scraper seat 16, and then adjust the relative position of the blade 131 of the scraper 13 and the guide surface 121 of the guide seat 12 (the bolt 161 can be loosened first when adjusting).

[0043] Specifically, the return spring 15 can be a compression spring, a tension spring or a torsion spring; the rotating shaft 14 can be a rigid latch or a spring pin. For example, when the return spring 15 is a compression spring, a spring assembly groove for installing the compression spring can be provided on the top of the tool base 11, and the axial ends of the compression spring respectively support the tool base 11 and the guide seat 12 to provide a return spring force.

[0044] In the flexible flat scraper tool 10 of the embodiment of the utility model, a protrusion 111 is provided on the top of the tool base 11, and a groove 123 is provided on the bottom of the guide seat 12. The protrusion 111 extends into the groove 123, and a first gap 124 is formed between the side wall of the protrusion 111 and the side wall of the groove 123; the first gap 124 is used to provide a movable space for the guide seat 12 to swing left and right.

[0045] In the flexible flat scraper tool 10 of the embodiment of the utility model, the protrusion 111 and the guide seat 12 are both provided with a shaft hole 17, and the shaft hole 17 of the protrusion 111 passes through the side wall of the protrusion 111, and the shaft hole 17 of the guide seat 12 passes through the side wall of the groove 123, and the shaft 14 is inserted into the shaft holes 17 of the protrusion 111 and the guide seat 12 at the same time, and a second gap 171 is formed between the outer wall of the shaft 14 and the inner wall of the shaft hole 17; the second gap 171 is used to provide a movable space for the guide seat 12 to swing left and right.

[0046] In the flexible flat scraping tool 10 of the embodiment of the utility model, the first gap 124 and the second gap 171 provide a floating activity space for the guide seat 12, referring to Figure 4 Combined with the rotating shaft 14, the guide seat 12 can realize flexible deflection in multiple directions and angles relative to the tool base 11. In addition, when the rotating shaft 14 adopts a spring pin, the elasticity of the spring pin will keep it in the original position in a shaking environment to prevent it from falling off.

[0047] The flexible flat scraping tool 10 of the utility model embodiment is provided with a guide surface 121 on the top of its guide seat 12. During the flat scraping process, the surface of the plate moves along the guide surface 121. Since the guide seat 12 can realize multi-directional and multi-angle flexible deflection relative to the tool base 11, when the surface of the plate is uneven or the plate is tilted, the guide seat 12 can adaptively adjust its own posture in real time, thereby driving the scraper 13 to make real-time adaptive adjustments, which helps to keep the scraper 13 (the blade 131) in continuous contact with the surface of the plate, and effectively avoid the scraper scratching the surface of the plate or failing to scrape off the residual glue line.

[0048] The flexible flat scraping mechanism of the embodiment of the utility model includes the above-mentioned flexible flat scraping tool 10 and two clamping seats 20 distributed up and down; in the flexible flat scraping mechanism, the number of flexible flat scraping tools 10 is two, and they are respectively arranged on the two clamping seats 20, and the clamping seats 20 are provided with rollers 21 at both ends of the flexible flat scraping tool 10.

[0049] In the prior art, when processing special plates with narrow widths, the stability of the plate fixation is poor, and the plate is prone to deflection during the working process, and the scraper is prone to scratching the surface of the plate, resulting in a decrease in the appearance quality of the plate, or even causing the plate to be scrapped.

[0050] To solve the above problems, the flexible flat scraping mechanism of the embodiment of the utility model provides multi-point support for the plate during processing through rollers 21 and guide seats 12, thereby improving the clamping stability, effectively avoiding accidental deflection of the plate, protecting the plate, and improving the processing quality.

[0051] In the flexible flat scraping mechanism of the embodiment of the utility model, when the guide surface 121 is in a horizontal state, the guide surface 121 is tangent to the circumferential surface of the roller 21. In addition, the flexible flat scraping mechanism also includes two driving cylinders 30, which are respectively connected to the two clamping seats 20, thereby driving the two clamping seats 20 to move up and down respectively to achieve the clamping function.

[0052] The working process of the flexible flat scraping mechanism of the utility model embodiment is roughly divided into three steps:

[0053] In the first step, when the plate has not reached the flat scraping position, the positions of the guide seat 12 and the scraper 13 and other parts are kept in the initial state (i.e., the reset state), such as Figure 8 As shown;

[0054] In the second step, when the sheet arrives at the designated position of the flat scraping station, the driving cylinder 30 is started, the sheet contacts the guide seat 12, and the cylinder thrust makes the guide seat 12 close to the surface of the sheet. The sheet moves along the guide surface 121 of the guide seat 12. Under the extrusion and push of the sheet, the return spring 15 is compressed. At this time, the guide seat 12 drives the scraper 13 to make real-time adaptive adjustments, so as to keep in continuous contact with the surface of the sheet and scrape away the residual glue line on the sheet. Fig. 9 As shown;

[0055] In the third step, after the plate leaves the flat scraping station, the return spring 15 rebounds and drives the guide seat 12 to rotate and reset, and the driving cylinder 30 releases the pressure to reset, and the current working cycle ends. Fig.10 shown.

[0056] The flexible flat scraping mechanism of the embodiment of the utility model can effectively avoid the situation where the scraper scratches the surface of the plate or fails to scrape away the residual glue line by adopting the above-mentioned flexible flat scraping tool 10.

[0057] The edge banding machine of the embodiment of the utility model includes the above-mentioned flexible flat scraping tool 10, or includes the above-mentioned flexible flat scraping mechanism; by adopting the above-mentioned flexible flat scraping tool 10 or the above-mentioned flexible flat scraping mechanism, it can effectively avoid the situation where the scraper scratches the surface of the plate or fails to scrape off the residual glue line.

[0058] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
