Detailed Description

The following specific examples are given by way of illustration only and not by way of limitation, and it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made in the examples without inventive faculty, and yet still be protected by the scope of the claims.

Embodiment 1, as shown in fig. 1-2, a bamboo striking mechanism includes a striking head 1 for pushing moso bamboos to advance forward and strike against a cutting die, the striking head 1 includes a main supporting cylinder 11 extending forward and backward, a moso bamboo pushing plate a fixed to a front side edge portion of the main supporting cylinder 11 and located in the cylinder and having a through hole a1 formed in a central region thereof, and a buffer plate b capable of passing through the through hole a1 forward and backward and abutting against the cutting die, the main supporting cylinder 11 may be made of a steel cylinder, the moso bamboo pushing plate a may also be made of a steel plate structure, and may also be made of other metal materials with relatively high strength, so that the moso bamboo pushing plate a may be directly and integrally connected to the main supporting cylinder 11, for example, directly formed during forging, and of course, the moso bamboo pushing plate a may also be welded to the front side edge portion of the main supporting cylinder 11 by welding, the main support cylinder 11 may be generally cylindrical. The buffer plate b may be made of steel plate, the through hole a1 is preferably a circular hole, and the overall external contour of the buffer plate b is in a shape of a round cake. The axes of the main support cylinder 11, the passage hole a1 and the buffer plate b should be kept in agreement and controlled in the front-rear direction. The diameter of the buffer plate b is preferably slightly smaller than the diameter of the through hole a1, that is, the buffer plate b and the through hole a1 form an annular gap, the size of the gap is as small as not more than one twentieth of the diameter of the buffer plate b, and the size of the buffer plate b is preferably controlled within one third to two thirds of the outer diameter of the main support cylinder 11.

The main supporting cylinder 11 is fixed with a driving shaft sleeve 2 which extends backwards and is used for driving the ram 1 to move forwards and backwards, the driving shaft sleeve 2 drives the ram 1 to move forwards and backwards, a moso bamboo pushing plate a can push the moso bamboo to a cutting die to cut or retreat to return to an original position for feeding, the buffer plate b is fixed with an inner shaft 3 which extends backwards and is sleeved in the driving shaft sleeve 2, the inner shaft 3 can pass forwards and backwards in the driving shaft sleeve 2, so that the driving shaft sleeve can be made smooth and can be added with machine oil and the like, the rear end part of the driving shaft sleeve 2 is fixed with an end part limiting part 4, the end part limiting part 4 can be a steel end cover with external threads, the inner surface of the rear end part of the driving shaft sleeve 2 is correspondingly arranged, and the end cover can be screwed to the rear end part of the driving shaft sleeve 2 to achieve better limiting. A buffering compression spring 5 extending in the front-rear direction is arranged between the inner shaft 3 and the end limiting piece 4, and the foremost part of the bamboo pushing plate a is positioned in front of the foremost part of the buffering plate b. The design aims to ensure that when the main support cylinder body 11 moves forwards and can push the moso bamboos to move forwards to the cutter die through the moso bamboo pushing plate a for sectioning operation until the moso bamboos approach the tail end of the moso bamboos, the inner mounting seat of the blades on the cutter die firstly passes through the section of the moso bamboo pushing plate a and can be abutted against the buffer plate b, the conventional ram does not push the moso bamboos forwards to cut on the blades at the time, and the design of the application ensures that the buffer plate b which is also positioned at the central position can have a space for moving backwards after being abutted against the cutter die and more accurately abutted against the inner mounting seat of the blades on the cutter die, the buffer plate b can contract backwards through the inner shaft 3 and the buffer compression spring 5, and in reverse, the main support cylinder body 11 and the moso bamboo pushing plate a can continuously push the moso bamboos forwards for a certain distance to push the moso bamboos to cut on the blades, the moso bamboo is cut more thoroughly, the effect is better, the elastic coefficient of the buffering compression spring 5 is controlled well, the situation that the buffering plate b retreats too much due to the too small elastic coefficient is avoided, and the moso bamboo pushing plate a can possibly collide with the blade too much when advancing. Then, after the cutting is finished, the main support cylinder 11 retracts, the inner mounting seat is separated from the buffer plate b, and the buffer compression spring 5, the inner shaft 3 and the buffer plate b return.

Further, the moso bamboo pushing plate a is in a funnel shape with the caliber gradually reduced from front to back and is provided with a conical inner surface a2 for contacting the rear end part of the moso bamboo. The funnel shape refers to a conical structure, the moso bamboo pushing plate a is in a conical cylinder structure with a front opening and a rear opening, namely the through hole a1, and then the inner mounting seat can easily abut against the buffer plate b, because the inner mounting seat of the cutting die is a structure which is smaller than the diameter of the buffer plate b. The inner cylinder surface of the conical cylinder structure of the bamboo pushing plate a with the structure is the conical inner surface a2, and the inclination angle of the generatrix of the conical inner surface a2 of the bamboo pushing plate a is preferably consistent with the inclination angle of the cutter die blade as much as possible, so that the bamboo pushing plate a can push the bamboos forwards to the cutter blade to a greater extent.

In addition, the buffer board b can be provided with a front limit groove b1 which extends backwards along the front side surface and is used for limiting the cutting die, and the limit is the inner mounting seat of the blade on the cutting die, so that when the rear end of the moso bamboo is cut and approached, a part of the backward section of the buffer board b is directly the front limit groove b1, on one hand, the inner mounting seat of the blade is better limited, the stability of the blade is better, the shaking is reduced, on the other hand, a groove depth which allows the inner mounting seat to enter the collision head and advance for a certain distance is directly formed on the buffer board b, namely, a section of the forward moving capability which is closer to the blade is naturally formed by the moso bamboo pushing board a, on the other hand, the contraction distance of the buffer compression spring 5 is relatively reduced, the linear type of the spring is better, and the risk of inversion radial deformation caused by too much contraction is avoided, because of the same advancing amount of the moso bamboo pushing plate a at the tail end of the moso bamboo, in the case of the front stopper b1, the compression distance of the buffer compression spring 5 is smaller than that in the case of the absence of the front stopper b1, that is, the front and rear groove depth of the front stopper b 1. In the operation process, a chain or other driving equipment is used for driving the collision head to move forward, so that the actual forward movement amount of the moso bamboo pushing plate a is controlled by the driving equipment to achieve the maximum forward movement amount which can be achieved by the application.

The rearward extending end of the front hub 21 is located as far as possible outside of the main support cylinder 11, while the rear hub 22 is preferably entirely outside of the main support cylinder 11. The inner shaft 3 can be inserted into the rear boss 22 from the front boss 21, and a portion of the front end of the inner shaft 3 is advanced beyond the front end of the front boss 21 in an uncompressed original state of the cushion plate b so that the inner shaft 3 has a backward contraction stroke, and then the stub shaft 3a to which the inner shaft 3 is connected is inserted into the more forward mounting fixing groove b2, and the end stop 4 is provided in the rear end portion of the rear boss 22.
