[0002] In the furniture processing, large wood is often required to be processed, such as overall planing, carving, etc. At this time, the wood needs to be placed on the processing machine and moved to the processing head through the transmission device. In this process, the fixing stability of the wood is required to be high. At present, most of the existing transmission devices use transmission rollers, belt-type circular transmission structures, or electric push rod-type reciprocating push structures; and for the above existing structures, when the wood is transported to the processing head, the corresponding drive components need to be powered off and paused to ensure that the wood can accurately correspond to the processing head.

DETAILED DESCRIPTION

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] Embodiment 1

[0035] In the embodiment of the present invention, a positioning transmission device in a wooden furniture processing technology is provided. Figure 1 As shown in FIG. 1 , it is a schematic diagram of the three-dimensional structure of the device. As can be seen from the figure, the device mainly includes the following structures:

[0036] A transmission assembly 2, wherein the transmission assembly 2 comprises two transmission rollers 21 and a transmission belt 22 sleeved on the transmission rollers 21;

[0037] The driving assembly 1 is used to realize intermittent transmission of the transmission assembly 2 under continuous driving, and the driving assembly 1 includes a driving gear 11 connected to one of the driving rollers 21, and a driving toothed plate 14 for cyclic transmission, and the driving toothed plate 14 is engaged with or disengaged from the driving gear 11 during the cyclic transmission;

[0038] Wherein: when the driving tooth plate 14 is meshed with the driving gear 11, the driving component 1 drives the transmission component 2 to transmit; when the driving tooth plate 14 is separated from the driving gear 11, the transmission component 2 stops positioning.

[0039] In summary, in the embodiment of the present invention, the continuous driving of the driving component 1 can effectively realize the intermittent transmission of the transmission component 2, thereby effectively avoiding the problem of frequent start and stop when using the traditional transmission device. Specifically, the practicable structure and driving method of the driving component 1 are as follows:

[0040] First, see Figure 3 As shown, the structure for realizing the circular transmission of the driving tooth plate 14 includes at least two first transmission wheels 12 and a first conveyor belt 13 sleeved on the first transmission wheels 12. The driving tooth plate 14 is installed on the first conveyor belt 13, and the length of the driving tooth plate 14 is less than the length of the first conveyor belt 13.

[0041] Specifically, for the convenience of illustration and description, only the state in which four first conveying wheels 12 are provided is shown in the figure, so that the first conveying belt 13 can form a quadrilateral conveying structure, and the driving gear plate 14 performs cyclic conveying along the quadrilateral.

[0042] In the figure, the driving gear 11 cooperating with the driving tooth plate 14 is located above the first conveyor belt 13. Correspondingly, it can be known that the driving tooth plate 14 can only engage with the driving gear 11 when it is transmitted to the highest position, and when it is located at other positions, the transmission component 2 is paused.

[0043] In summary, the principle of the drive assembly 1 to realize the intermittent drive of the transmission assembly 2 is as follows: the first transmission wheel 12 is driven to realize the transmission of the first conveyor belt 13, thereby driving the drive tooth plate 14 to move, and when the drive tooth plate 14 moves to the highest position, one end of the drive tooth plate 14 gradually approaches the drive gear 11 and forms an engagement with the drive gear 11, thereby starting to drive the drive gear 11 to rotate, and then drives the drive roller 21 corresponding to the drive gear 11 to rotate, and the drive roller 21 drives the drive belt 22 to transmit, thereby driving the wood placed on the drive belt 22 to move to transmit to the processing position; with the continuous transmission of the first conveyor belt 13, the drive tooth plate 14 gradually passes through the drive gear 11 until the other end is separated from the drive gear 11, and the transmission of the first conveyor belt 13 can no longer drive the drive gear 11 to rotate, and at this time the drive gear 11 and the entire transmission assembly 2 remain fixed and motionless, forming a positioning state; correspondingly, according to the length design of the drive tooth plate 14, it is ensured that when the transmission assembly 2 is positioned, the wood thereon can be effectively transmitted to the corresponding processing cutter head, so as to facilitate positioning processing.

[0044] As mentioned above, regarding the length design of the driving tooth plate 14, its structure and method are as follows:

[0045] Please continue reading Figure 3-Figure 7 As shown, the driving tooth plate 14 is composed of a plurality of unit plates, each of which is detachably connected to the first conveyor belt 13, and each of which includes a T-shaped connector 141 and a panel 142 that cooperate with each other, the a surface of the T-shaped connector 141 is connected to the first conveyor belt 13, and the b surface is connected to the panel 142, and the width of the a surface is smaller than the width of the b surface, and the panel 142 is provided with a tooth groove that engages with the driving tooth plate 14.

[0046] As can be seen from the above, when designing and adjusting the driving tooth plate 14, it can be completed by increasing or decreasing the number of unit plates; specifically, regarding the disassembly structure and method between the unit plate and the first conveyor belt 13, the following two possible implementation methods are provided:

[0047] First embodiment

[0048] Please continue reading Figure 4-Figure 5 As shown, the b-side of the T-shaped connector 141 is welded and fixed to the panel 142, and a plurality of groups of first fixing holes 131 are equidistantly provided on the first conveyor belt 13, and each group of first fixing holes 131 is detachably connected to a T-shaped connector 141 through bolts. It can be seen that when the unit board is fixed, the a-side of the T-shaped connector 141 is pressed against the first conveyor belt 13 and made to correspond to a group of first fixing holes 131, and then the bolts are passed through the first fixing holes 131 and screwed into the T-shaped connector 141, and the fixed connection is completed; when disassembling, the bolts can be removed.

[0049] In this embodiment, further, each first conveying wheel 12 is provided with an annular guide groove 121, and the guide groove 121 corresponds to the first fixing hole 131. Therefore, when the first conveying belt 13 is conveyed, the fixed bolts are conveyed through the guide groove 121 in a staggered manner, thereby avoiding the mismatch between the first conveying wheel 12 and the first conveying belt 13 caused by the fixing of the bolts.

[0050] Second embodiment

[0051] Please continue reading Figure 6-Figure 7 As shown, the b surface of the T-shaped connector 141 protrudes outward to form two symmetrically distributed buckles 143 , and two buckles 143 are symmetrically opened on the panel 142 , and the two buckles 143 are respectively engaged in the two buckle slots 145 .

[0052] In this embodiment, further, the two buckles 143 are each provided with a second fixing hole 144 , and the second fixing hole 144 is detachably connected to the panel 142 via bolts.

[0053] As can be seen from the above, in this embodiment, the T-shaped connector 141 and the first conveyor belt 13 are non-detachable, and the unit board is disassembled and assembled by the T-shaped connector 141 and the panel 142; and when installing the panel 142, the two slots 145 on the panel 142 are correspondingly engaged in the two buckles 143, and then the bolts are screwed into the second fixing holes 144 so that the bolts are screwed into the panel 142 to complete the fixed connection; when disassembling, just remove the bolts.

[0054] Specifically, as can be seen from the figure, the fixing positions are set at both ends of the unit plate, so that the fixing operation of the unit plate is more convenient.

[0055] For the above two embodiments, the design adjustment of the driving tooth plate 14 is described; if only the length of the driving tooth plate 14 is increased or decreased, the corresponding positioning time will be reduced or increased. Therefore, if it is desired to change the length of the driving tooth plate 14 without changing the positioning time (processing time), the entire first conveyor belt 13 needs to be replaced, and the replacement method of the first conveyor belt 13 is as follows:

[0056] At least two first transmission wheels 12 include an immovable driving wheel and at least one movable driven wheel, and when the driven wheel moves, the first conveyor belt 13 can be replaced. The driving wheel can be driven to rotate by a motor (not shown in the figure), and the driven wheel can be driven to move by an electric push rod (not shown in the figure); specifically, when the driven wheel moves, the distance between it and the driving wheel can be effectively changed, thereby changing the perimeter of the quadrilateral shown in the figure, and correspondingly changing the required length of the first conveyor belt 13, thereby meeting the requirement of unchanged positioning time.

[0057] Embodiment 2

[0058] In the embodiment of the present invention, a positioning transmission device in a wooden furniture processing technology is provided. Figure 2 As shown in FIG. 1 , it is a schematic diagram of the three-dimensional structure of the device. As can be seen from the figure, the device mainly includes the following structures:

[0059] The transmission assembly 2 includes two transmission rollers 21 and a transmission belt 22 sleeved on the two transmission rollers 21;

[0060] The driving assembly 1 is used to realize intermittent transmission of the transmission assembly 2 under continuous driving, and the driving assembly 1 includes a driving gear 11 connected to one of the driving rollers 21, and a driving toothed plate 14 for cyclic transmission, and the driving toothed plate 14 is engaged with or disengaged from the driving gear 11 during the cyclic transmission;

[0061] It can pass through the processing area 3 of the transmission assembly 2;

[0062] The material pressing assembly 4 is at least arranged on one side of the processing area 3 , and the material pressing assembly 4 is located above the transmission assembly 2 .

[0063] In summary, the transmission and driving modes of the transmission assembly 2 and the driving assembly 1 in this embodiment are the same as those in the first embodiment.

[0064] In this example, please continue to refer to Figure 8 As shown, the specific structure of the pressing component 4 is as follows:

[0065] The pressing assembly 4 includes an inverted mounting frame 41, a lifting cylinder 42 fixed to the top of the mounting frame 41, and a second conveyor belt 43 and a second conveyor wheel 44 installed inside the mounting frame 41. Two second conveyor wheels 44 are symmetrically arranged, and the second conveyor belt 43 is sleeved on the two second conveyor wheels 44.

[0066] It can be seen that when the transmission component 2 is used to transmit wood, the pressing component 4 can be used to press the wood to ensure the stability of the wood during transmission; the specific principle is:

[0067] Place the wood on the transmission assembly 2, start the lifting cylinder 42, and press down the mounting frame 41 and the second conveyor belt 43 and the second conveyor wheel 44 located inside the mounting frame 41. The second conveyor belt 43 cooperates with the transmission belt 22 to achieve the effect of fixing the wood. When the wood is transmitted along with the transmission belt 22, the second conveyor belt 43 is driven by friction to be transmitted, thereby driving the two second conveyor wheels 44 to rotate, thereby ensuring the effective transmission of the wood.

[0068] In addition, in this embodiment, the transmission assembly 2 also includes a support plate 23 located between the two transmission rollers 21, and a plurality of balls 24 in contact with the transmission belt 22 are embedded on the top of the support plate 23, and the second transmission wheel 44 at the start of the pressing assembly 4 is located directly above the first ball 24. Based on this, a support is formed below the lower wood to prevent the transmission belt 22 from being deformed due to excessive weight of the wood; wherein the setting of the ball 24 is used to reduce the friction between the transmission belt 22 and the support plate 23, reduce the wear of the transmission belt 22, and ensure that the transmission belt 22 can effectively drive the wood for transmission; and the second transmission wheel 44 at the start ( Figure 8 The first ball 24 can also achieve the effect of rigidly clamping the wood, further ensuring the stability of the wood transmission.

[0069] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0070] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
