Description

Technical Field

[0001] The invention belongs to the field of auxiliary accessories for laminating presses, and in particular relates to a top block of a top plate system of a laminating press. Background Art

[0002] At present, when solid wood boards and artificial boards are laminated with laminating machines, in order to ensure a good edge banding effect, a pad must be placed under the workpiece, and the size of the pad must be slightly smaller than the workpiece. The traditional method of manually placing the pad requires manual calculation of the pad size, manual placement and recycling of the pad. Due to the diversity of types and sizes of the processed workpieces, pads must be made according to the size of each workpiece. The demand for pads is high, resulting in a waste of pad raw materials and storage space. Manually made pads have high technical requirements for operators, and the efficiency of manual operation is very low, which wastes human resources, affects work efficiency and product quality, and cannot form production. In response to the above problems, the following technical means are currently used:

[0003] (1) Install infrared scanning automatic blocks on the work surface. See patent publication number CN205221354U, which discloses a block-type automatic pad feeding tray. The tray uses a photoelectric sensor for scanning. When it detects that the four light-transmitting holes on the left and right sides are blocked by the workpiece, it is judged that the block is completely covered, and the corresponding lever under the uncovered block is controlled to move, forming a height difference between the blocks. This automatic block tray achieves the purpose of automatic padding, but the structure has complex matching parts, high processing accuracy requirements, high requirements for the working environment, and is prone to malfunction in workshops with slight dust. The tray runs slowly during the scanning process, affecting efficiency, and has high procurement and maintenance costs.

[0004] (2) Using the gravity of the workpiece as a trigger condition to automatically lift the bottom of the workpiece. See Chinese patent application CN110561879A, a pad-free top block for a laminating machine, the top block includes a top block body and a pad block, an active rack is installed in the top block body, and a meshing gear and a driven rack are engaged; the two racks are meshed with the gear in opposite directions, and the gravity of the workpiece drives the active rack, and the locking and release of the pad block are achieved through the reverse movement of the active rack and the driven rack. However, the matching of the structural components requires precision, and in actual use, it is affected by friction and other factors, with a high failure rate, and cannot adapt to high-frequency use in actual production. Summary of the invention

[0005] The present invention aims to overcome the deficiencies of the prior art and provide a top block of a top plate system of a laminating machine which has high processing efficiency, low cost, safety and effectiveness, low failure rate, and stability and reliability.

[0006] To solve the above technical problems, the present invention is achieved as follows:

[0007] A top block of a top plate system of a laminating machine comprises an outer sleeve; a spring and a probe are respectively arranged in the inner cavity of the outer sleeve; the spring is placed between the probe and the inner cavity of the outer sleeve; a pad is arranged at the lower part of the outer sleeve; the top area of ​​the pad is movably connected to the lower part of the outer sleeve; a probe locking component is arranged in the lower area of ​​the probe; and a pad locking component is arranged in the upper area of ​​the pad at a position corresponding to the probe locking component.

[0008] As a preferred solution, the top of the outer jacket of the present invention is provided with an assembly opening; a top cover is fixedly provided on the assembly opening; and the top of the probe passes through the middle hole of the top cover.

[0009] Furthermore, the probe locking component of the present invention may be an iron block; and the pad locking component may be a magnetic block.

[0010] Furthermore, the lower part of the probe of the present invention is divided into left and right sides, one side of which is connected to the top of the spring, and the lower area of ​​the other side is fixedly embedded in the probe locking component; the bottom of the spring is connected to the bottom of the inner cavity of the outer sleeve.

[0011] Furthermore, the present invention provides a support frame on the outside of the outer jacket.

[0012] Furthermore, the present invention has a silicone pad fixedly provided on the top cover.

[0013] Furthermore, in the present invention, a pad stopper is fixedly provided on the side of the pad at the lower part of the outer sleeve.

[0014] Compared with the manual placing of the plate, the present invention can save manual operation, and there is no need for workers to choose the placing plate by themselves. The workers only need to place the workpiece on the workbench. This can save manpower in the process and lower the technical threshold for workers. Compared with the automatic top block of the scanning method, the present invention can save scanning costs. At the same time, the scanning type automatic top plate needs to set up a scanning link, and the top block of the top plate system of the laminating machine of the present invention adopts a purely mechanical principle, which can save the scanning step, thereby saving the process flow and improving work efficiency. Compared with similar top blocks, the structure of the present invention is simpler, and the height of the top block itself is reduced. It has better applicability, a more stable structure, and a significantly reduced failure rate. BRIEF DESCRIPTION OF THE DRAWINGS

Of course, the probe locking component 8 can be an iron block or a magnetic block. The pad locking component 6 set on the corresponding pad 7 can also be a magnetic block or an iron block. Here, the probe locking component 8 of the present invention adopts an iron block; the pad locking component 6 adopts a magnetic block. In this way, the locking of the pad 7 is achieved by the magnetic interaction between the probe locking component 8 and the pad locking component 6. A support frame 13 is provided on the outside of the jacket 4 of the present invention. The support frame 13 is provided mainly to limit the jacket 4 to ensure that it can move up and down longitudinally.

[0027] The present invention is provided with a silicone pad 2 fixedly on the top cover 11. The present invention is provided with a pad stopper 14 fixedly on the side of the pad 7 at the lower part of the outer cover 4. The pad stopper 14 can act as a travel switch, and when the pad 7 rotates downward around the rotating shaft 9 to the position of the pad stopper 14, the pad 7 stops moving.

[0028] See also Figure 4 and Figure 5 As shown, when the present invention is in use, it is fixed on a workbench in an array arrangement, the main machine is connected to the placing table, the workbench can slide between the placing table and the main machine on the guide rail, there is a reset lifting platform 17 controlled by a two-stage cylinder under the placing table, and there is a main machine lower tray 15 at the bottom of the main machine which is controlled to rise and fall by an oil cylinder.

[0029] In the specific design, the main structure of the present invention includes a jacket 4, a spring 5 and a probe 1 are installed inside the jacket 4, and a probe locking component 8 is embedded below the probe 1, preferably an iron block. A top cover 11 is installed on the jacket, and a pad 7 is connected to the lower rotating shaft 9, and the pad 7 can rotate around the rotating shaft 9. The pad 7 is embedded in the pad locking component 6, preferably a magnet. The probe 1 adopts a two-side structure in which the upper section of the rod column 101 is divided into one side of the rod column 102 and the other side of the rod column 103. The one side of the rod column 102 contacts the upper end of the spring 5, and the other side of the rod column 103 extends downward for installing the probe locking component 8. The top cover 11 and the silicone pad 2 are both annular structures, the purpose of which is to seal the internal structure and the silicone pad 2 can play an anti-slip role on the workpiece. The pad 7 is a plastic block, which is installed and connected to the jacket 4 through the rotating shaft 9, and there is a hole on the end face for embedding the pad locking component 6.

[0030] See also Figure 1 and Figure 5 As shown, before placing the workpiece, the pad 7 is in Figure 3The reset lifting platform 17 is attached to the bottom surface, and the magnet and the iron block attract each other, so that the pad 7 cannot rotate. After the workpiece is placed, the probe 1 moves downward under the pressure of the workpiece gravity, squeezing the spring 5. At this time, the magnet and the iron block are offset from each other. At this time, the reset lifting platform 17 is driven by the two-stage cylinder 18 to move down and leave the workbench 20. The pad 7 will rotate to the position by itself due to the loss of magnetic attraction. Figure 2 position, thereby achieving the purpose of elongation.

[0031] See also Figure 5 As shown, after the workbench enters the main machine from the placement table, the cushion block 7 is in the position under the lifting action of the main machine lower tray 15 at the top of the oil cylinder 16. Figure 2 The top block of the position is better than Figure 3 The height of the position should be high so as to achieve the effect of raising the height of the workpiece.

[0032] When the workbench is ready to be put out, the reset lifting platform 17 inside the placing table rises upward under the action of the first cylinder of the two-stage cylinder 18, and this height is higher than that in the normal state. Figure 3 The bottom surface of the pad 7 at the position is slightly lower, but Figure 2 The bottom surface of the pad 7 at the position is high, and as the platform moves, Figure 2 The pad at the position will hit the reset lifting platform 17, and the rotation angle gradually approaches Figure 3 When the workbench is ready, the reset lifting platform 17 continues to rise to the same position as the workbench under the action of the second cylinder of the two-stage cylinder 18. Figure 3 The bottom surface of the position pad is at the same height. At this time, the pad locking component 6 and the probe locking component 8 rotate to the contact position. Under the action of magnetic force, it is ensured that the pad 7 will not rotate under the action of gravity even without the support of the reset lifting platform 17. After the workpiece is placed, the two-stage cylinder 18 is completely lowered, and the reset baffle platform will not hinder the entry of the workbench.
