Description

Technical Field

[0001] The utility model relates to the technical field of machining equipment, in particular to a streamlined feeding and discharging device for a profiling machine. Background Art

[0002] A mini Christmas tree is made by clamping a row of thin plastic strips (plastic hairs) with a V-shaped wire, and twisting the wire to make the plastic strips spread out in a circular shape and be fixed by the twisted wire (this step is the embryo making, and the equipment used is the embryo making machine). Finally, the spread plastic strips are trimmed into a conical Christmas tree shape by a semi-automatic profiling machine; the twisted wire is the trunk of the Christmas tree, and the thin plastic strips are the branches of the Christmas tree.

[0003] The semi-automatic profiling machine on site fixes the Christmas tree embryo parts that have been made but not trimmed into a pagoda shape to the rotating main shaft through both ends of the wire stranding in the center. Under the state that the embryo parts rotate in the center, the profiling tool on one side performs inclined hair cutting to make the embryo parts become Christmas tree handicrafts with the wire stranding as the trunk. For the existing semi-automatic profiling machine, when loading the embryo parts, it is necessary for workers to align both ends of the wire stranding and ensure that they are clamped to the main shaft fixture. After profiling is completed, the workers then manually remove the used ones and replace them with new embryo parts. This kind of loading method has extremely low efficiency, thus greatly prolonging the entire processing time, and further resulting in an increase in implicit costs. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the technical problem to be solved by the utility model is to provide a streamlined feeding and discharging device for a profiling machine, which can quickly complete the loading and unloading of Christmas tree embryo parts when profiling the Christmas tree.

[0029] The embodiments of the technical solutions of the present utility model will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solutions of the present utility model more clearly, so they are only examples and cannot be used to limit the protection scope of the present utility model.

[0030] Please refer to Figures 1 to 3 , the present utility model provides a streamlined inlet and outlet device for a profiling machine, including a frame 100, a fixture 200, an intermittent opening and closing drive mechanism 300, a storage mechanism 400, and an intermittent pushing mechanism 500.

[0031] Specifically, the frame 100 is used to install components and can move towards the trimming tool. The fixture 200 includes two clamping plates 210 arranged oppositely up and down, and the two clamping plates 210 are arranged parallel and spaced apart up and down to form a clamping opening 220, and the clamping opening 220 is used to clamp and fix the end of the Christmas tree embryo part 1.

[0032] The intermittent opening and closing drive mechanism 300 is connected to two clamping plates 210 and is used to drive the two clamping plates 210 to separate or close. A plurality of Christmas tree blank parts 1 are stacked from bottom to top in the inner cavity of the stock storage mechanism 400 in a compliant manner and can freely fall. Both the bottom end and the top end of the stock storage mechanism 400 are in an open state, and the end of the Christmas tree blank part 1 moved out from the bottom end of the stock storage mechanism 400 can move from the side close to the trimming tool to the clamping opening 220 and push out the Christmas tree blank part 1 located in the clamping opening 220. The intermittent feeding mechanism 500 is used to intermittently push out the Christmas tree blank parts 1 in the inner cavity of the stock storage mechanism 400 from the bottom end of the stock storage mechanism 400.

[0033] During use, first, a plurality of Christmas tree blank parts 1 are stored in the stock storage mechanism 400. When the intermittent feeding mechanism 500 pushes out the lowermost Christmas tree blank part 1, the intermittent opening and closing drive mechanism 300 drives the two clamping plates 210 to separate, and the end of the Christmas tree blank part 1 drops into the clamping opening 220. Subsequently, the intermittent opening and closing drive mechanism 300 drives the two clamping plates 210 to close to clamp the end of the Christmas tree blank part 1. Then, the rack 100 is pushed towards the trimming tool direction manually or by a mechanical mechanism, and the Christmas tree blank part 1 can be trimmed and shaped through the trimming tool direction.

[0034] After trimming one Christmas tree blank part 1, the rack 100 is retracted to its original position, and the intermittent feeding mechanism 500 feeds again. At the same time, the intermittent feeding mechanism 500 drives the two clamping plates 210 to separate, and the Christmas tree blank part 1 falling from the stock storage mechanism 400 enters the clamping opening 220 again, pushing out the Christmas tree blank part 1 that has been trimmed in the clamping opening 220. The intermittent opening and closing drive mechanism 300 drives the two clamping plates 210 to close again to clamp the end of the Christmas tree blank part 1. Then, the rack 100 is manually pushed towards the trimming tool direction, and the Christmas tree blank part 1 is trimmed and shaped again through the trimming tool direction. The above actions are repeated until all the Christmas tree blank parts 1 are trimmed.

[0035] By adopting the above-mentioned trimming machine's streamlined loading and unloading device, the loading and unloading work of the Christmas tree blank parts 1 can be completed automatically or semi-automatically, thus greatly improving the efficiency. At the same time, during the loading and unloading process, human hands do not come into contact with the device, thus greatly improving the safety.

[0036] In this embodiment, the intermittent opening and closing drive mechanism 300 includes a first piston cylinder 310, a first piston, a first piston rod 320, and an inflation device (not shown in the drawings). The first piston cylinder 310 is fixed on the frame 100 and is located between the two clamping plates 210. There are two first pistons, and the two first pistons are arranged at intervals within the first piston cylinder 310. The cavity between the two first pistons is the first air storage cavity. A first piston rod 320 is provided on each first piston. The ends of the two first piston rods 320 extend outwards and are respectively connected to the clamping plates 210 on the same side. The inflation device is communicated with the first air storage cavity through a first air pipe, and the inflation device can inflate or deflate.

[0037] During use, when inflating the first air storage cavity, the two first pistons can be driven to move away from each other, thereby driving the two clamping plates 210 to separate. On the contrary, when deflating, the two clamping plates 210 can be driven to close. It should be noted that in specific implementation, the inflation device can be an inflation device with inflation and deflation functions in the prior art. During use, the inflation or deflation can be controlled by respectively pressing the inflation or deflation start buttons of the inflation device with two feet.

[0038] In this embodiment, the stock storage mechanism 400 includes a stock storage cylinder 410 and a stopper 420. The stock storage cylinder 410 has a stock storage cavity extending upwards, and a plurality of Christmas tree blanks 1 can be stacked in the stock storage cylinder 410 from bottom to top in a compliant manner. The stopper 420 is arranged in the stock storage cavity, fixed on the bottom wall of the stock storage cavity, and close to the bottom end of the stock storage cavity, and can block the Christmas tree blanks 1 in the stock storage cavity. A channel is formed by arranging a gap between the top end of the stopper 420 and the top wall of the stock storage cavity, and the Christmas tree blanks 1 can pass through the channel; the intermittent feeding mechanism 500 is used to push the intermittent Christmas tree blanks 1 close to the stopper 420 into the channel.

[0039] Specifically, the intermittent feeding mechanism 500 includes a push rod 510 and a push driving member 520. The lower surface of the stock storage cylinder 410 is provided with an insertion hole communicated with its inner cavity, and the insertion hole is arranged close to the stopper 420. The front end of the push rod 510 can be inserted into the insertion hole and push the first Christmas tree blank 1 close to the stopper 420 upwards so that the Christmas tree blank 1 can move over the stopper 420 and then move into the channel by gravity. The push driving member 520 is connected to the rear end of the push rod 510 and is used to push the push rod 510 to insert into or withdraw from the insertion hole.

[0040] When in use, in a normal state, the push rod 510 is blocked in the insertion hole and supported on the first Christmas tree blank 1 near the block 420 to flip up. When the driving member 520 drives the push rod 510 to insert, the first Christmas tree blank 1 near the block 420 can be pushed up, so that it can flip over the block 420 and move to the channel by gravity, and finally flow out of the storage barrel 410 and insert into the clamp 220. When the push rod 510 retreats, under the action of gravity, the Christmas tree blank 1 in the storage barrel 410 moves down in sequence until it is blocked by the block 420.

[0041] In a specific implementation, a guide surface 421 may be provided on the side of the stopper 420 close to the Christmas tree blank 1, and the top of the guide surface 421 is inclined toward the bottom end of the storage barrel 410, so that the Christmas tree blank 1 can be conveniently moved along the guide surface 421 into the channel.

[0042] In this embodiment, the push drive member 520 includes a second piston cylinder 521, a second piston, and a second plug rod 522. The second piston cylinder 521 is fixed to the frame 100, and the second piston is arranged in the second piston cylinder 521, and a second air storage chamber is formed between the second piston and the second piston cylinder 521. The second plug rod 522 is arranged on the side of the second piston away from the second air storage chamber, and extends from the second piston cylinder 521 to abut against the end of the push rod 510. When the second plug rod 522 is extended or retracted, it can drive the push rod 510 to insert or withdraw from the jack. The second air storage chamber is connected to the first air pipe through the second air pipe.

[0043] When the inflating device is inflated, the second piston pushes the second plug rod 522 to extend and push the push rod 510 into the storage tube 410. On the contrary, when the inflating device is deflating, the second piston drives the second plug rod 522 to retract. In addition, since the second air storage chamber is connected to the first air pipe through the second air pipe, the two first plug rods 320 and the second plug rod 522 can be driven to move at the same time by the same inflating device, so that the clamping plate 210 and the push rod 510 can be moved synchronously to ensure smooth loading and unloading.

[0044] The specific method of using the above-mentioned streamlined inlet and outlet device of the trimming machine is as follows:

[0045] When in use, first store multiple Christmas tree blanks 1 in the storage mechanism 400, the Christmas tree blank 1 at the bottom is blocked by the block, and the inflation device is started to inflate. While driving the two clamps 210 apart, the driving push rod pushes the Christmas tree blank 1 at the bottom into the channel, and the Christmas tree blank 1 falls freely into the clamp 220. Then the inflation device evacuates air, driving the clamps 210 to close and clamp the ends of the Christmas tree blank 1 while the push rod 510 retreats. Then, the frame 100 is pushed to move in the direction of the pruning tool by manual or mechanical means, and the shape of the Christmas tree blank 1 can be modified in the direction of the pruning tool.

[0046] After completing the trimming of a Christmas tree blank 1, the rack 100 is retracted to its original position. Repeat the above actions so that the Christmas tree blank 1 that has fallen from the stock storage mechanism 400 enters the clamping jaws 220 again. Push out the Christmas tree blank 1 that has been trimmed and is located within the clamping jaws 220. The intermittent opening and closing drive mechanism 300 drives the two clamping plates 210 to close again to clamp the end of the Christmas tree blank 1. Subsequently, manually push the rack 100 towards the trimming tool again. Modify and shape the Christmas tree blank 1 again through the trimming tool. Repeat the above actions in a cycle until all the Christmas tree blanks 1 are trimmed.

[0047] By adopting the above-described in-line feeding and discharging device for the shaping machine, the feeding and discharging of the Christmas tree blanks 1 can be automatically or semi-automatically completed, thus greatly improving the efficiency. At the same time, during the feeding and discharging processes, the human hand does not come into contact with the device, thus greatly enhancing the safety.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the various embodiments of the present invention, and they should all be covered within the scope of the claims and the description of the present invention.
