Then the first pusher 101 is reset.

In this embodiment, the first elastic pressing roller 205 is used as an elastic pressing member and disposed between the feeding mechanism 1 and the drilling mechanism 2, and the first elastic pressing roller 205 with elastic pressure provided by the spring assembly 204 and the sliding plate 7 are vertically matched to clamp and position the plastic foam strip, so as to facilitate smooth and accurate completion of drilling.

In this example, the drilling mechanism 2 includes a drilling assembly mounted on the elevator base, the drilling assembly includes a plurality of drill bits 206 driven by the drilling motor 202 through the gear box 203 to rotate, the sliding plate is provided with matching holes 703, and the number and positions of the matching holes 703 correspond to the drill bits 206. The elevator base is driven by the drilling cylinder 201 to linearly ascend and descend up and down, the drill bit 206 descends and rotates to drill a plurality of through holes on the plastic foam strip below, and then the drill bit 206 ascends to reset.

Referring to fig. 3, in this example, the sliding plate 7 below the drilling mechanism 2 and the cutting mechanism 3 is provided with a strip-shaped slot hole 701 penetrating through the two mechanisms, two second pushing members 110 are arranged corresponding to the slot hole 701, the second pushing members 110 are fixedly connected with a piston rod of a lifting cylinder 109, the lifting cylinder 109 is installed on a sliding base 108, the sliding base 108 is arranged on the guide rail 107 through a slider, and the sliding base 108 is connected with the second cylinder 106; when the second pushing member 110 is lifted up, it passes through the slot hole 701 and acts on the through hole of the plastic foam strip, at this time, the second cylinder 106 is actuated, and the second pushing member 110 continues to push the plastic foam strip, which has completed the drilling, toward the cutting mechanism 3.

In this example, a second elastic pressing roller 305 serving as an elastic pressing member is arranged between the drilling mechanism 2 and the cutting mechanism 3, and the second elastic pressing roller 305 and the sliding plate 7 are matched up and down to clamp and position the plastic foam strip; in this example, the sliding plate 7 on both sides of the plastic foam strip is correspondingly provided with left and right clamping and positioning assemblies 704 (only the left clamping member is shown).

The cut substrate is pushed by the further stepped plastic foam strip and falls from the end of the slide 7 into a collection container below. The operation is circulated in such a way. And continuously carrying out automatic through hole drilling processing and matrix cutting molding on the plastic foam board.

Example 2: referring to fig. 4 and 5, the difference from embodiment 1 is that: in this example, the intermittent stepping driving mechanism is a mechanism composed of a sprocket 911 and a chain 910 driven by a stepping motor, and the pushing members a908 and B909 are uniformly distributed on a closed loop formed by the chain 910.

As shown in fig. 4, four plastic foam strips are stacked on skid 906, supported by the sides of material rack 902. The four plastic foam strips are named as strip 900, strip 901, strip 915 and strip 916 from bottom to top in sequence.

The pushing piece A908 acts on the tail end of the strip 900, and pushes the strip 900 to enter the drilling mechanism 904 and the cutting mechanism 905 along the sliding plate 906 through pressing the elastic roller 903, so as to complete the matrix processing of the firecracker liner. The slide 906 is provided with left and right clamping positioning plates 907 on both sides.

After the strip 900 is exhausted, the strip 901 drops down onto the skid 906 due to its own weight. At this time, the pusher a908 is located in front of the web 901 and cannot push the web 901, but the pusher B909 completes the pushing operation. Next, the strip 915 is pushed by the pushing member a 908. The strip 916 is pushed by the pusher B909. The two material returning parts work in a circulating mode. It can be inferred that: in other embodiments, more pushing elements can be arranged to work in a circulating mode.

In this example, the length of the chain 910 between the pusher a908 and the pusher B909 is greater than the length of the plastic foam strip, and there is a length difference of H between the two. The function is as follows: after the bar 900 is used up, the bar 901 falls down based on self weight, the head end of the bar 901 is close to the pushing element a908, and a gap H exists between the tail end of the bar 901 and the pushing element B909, so that time is reserved to ensure that the bar 901 falls in place, the situation that the pushing element B909 is padded below the bar 901 is avoided, and the device is ensured to work smoothly and reliably.

Example 2 also differs from example 1 in that: the drilling assembly includes a plurality of circular-blade drilling tools 913 driven by a drilling motor through a gear box, as shown in fig. 5, the circular-blade drilling tools 913 have circular-blade edges 914, and the circular-blade drilling tools 913 are lowered to rotate to cut the plastic foam strips to drill through holes. In order to avoid the cut plastic foam remaining in the inner cavity of the cutter, a lifting poker 912 can be further arranged, and the lifting poker 912 and the reset cutter form relative movement through an elastic device or a driving mechanism to clean the plastic foam possibly remaining in the inner cavity of the cutter.

The foregoing embodiments are merely for clarity of explanation, and are not to be construed as limiting the present invention. The utility model discloses have known multiple substitution or warp in this technical field, do not deviating from the utility model discloses under the prerequisite of essence meaning, all fall into the utility model discloses a protection scope.
