Description

Technical Field

[0001] This utility model relates to a locking device for the rear push plate of a vertical feeding shredder, belonging to the technical field of tobacco processing equipment. Background Technology

[0002] The vertical feeding shredder is a key piece of equipment in the tobacco production line. It uses a feeding device to transport tobacco leaves into the equipment. The equipment has a pusher plate at the rear. After production is completed, the pusher plate is lifted to pour out the exhaust tobacco. The pusher plate is heavy and difficult and dangerous for a single person to hang. The movement trajectory of the pusher plate is limited to facilitate single-person operation.

[0003] The existing pusher plate is heavy because it applies pressure to the tobacco leaves to make them move forward smoothly. After production, when opening it, one person needs to lift the pusher plate with one hand and use the other hand to engage the positioning pin with the opening slot on the side of the pusher plate to open and position it. This process is difficult and dangerous. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a locking device for the push plate of a vertical feeding shredder. This locking device can not only automatically engage during the opening process, but also can be opened and closed by a single person. The process is safe and effective.

[0005] To solve the above problems, the specific technical solution of this utility model is as follows: A pusher plate locking device for a vertical feeding shredder, wherein the pusher plate is connected to the top plate of the cabinet via a rotating shaft; both sides inside the cabinet are respectively hinged to one end of a support rod via pins; slide rails are provided on both sides of the outer surface of the pusher plate, and sliders are slidably connected on the slide rails, and the other end of the support rod is hinged to the slider; a locking connector is provided on the slider, and a locking limit device is provided on the back of the pusher plate, wherein when the slider reaches the designated position, the locking connector and the locking limit device lock and limit the position.

[0006] The locking and limiting device includes a locking seat, a spring, and a telescopic pin; the locking seat is fixed to the inner side of the slide on the back of the smoke pusher, and the telescopic pin is positioned in the locking seat by the spring; when the locking head passes the telescopic pin, the telescopic pin engages with the inner end face of the locking head.

[0007] The snap-fit ​​connector has a frustum structure, and the telescopic pin has a right-angled triangle cross-section. When the telescopic pin engages with the snap-fit ​​connector, the large-diameter end face of the snap-fit ​​connector contacts and limits the movement of the right-angled side of the telescopic pin.

[0008] The center of the snap-fit ​​connector is connected to the slider via a connecting rod. A guide head is provided on the connecting rod. The guide head has a frustum structure and its direction is opposite to that of the snap-fit ​​connector. The large diameter of the guide head is equal to the large diameter end of the connecting rod. The guide head has a sliding distance of 2 to 10 cm on the connecting rod.

[0009] The vertical feeding shredder's rear push plate clamping device of this application adopts the above-described structure and has the following advantages: 1. During the upward lifting of the smoke pusher, the slider moves the locking connector. When it passes the telescopic pin, the telescopic pin first retracts and then extends to limit the locking connector, thereby ensuring that the smoke pusher is safely and firmly positioned and will not swing downward. 2. A guide head is also provided on the connecting rod. When the pusher plate continues to be raised, the telescopic pin cooperates with the guide head. When it falls, the gap of the locking is closed by the guide head, so the locking joint and the telescopic pin will no longer cooperate. The pusher plate will continue to swing down until it returns to the working position. Attached Figure Description

[0016] like Figure 1 , Figure 2 and Figure 6 As shown, a pusher plate locking device for a vertical feeding shredder includes a pusher plate 2 connected to the top plate of a cabinet 1 via a rotating shaft; both sides of the pusher plate 2 are hinged to one end of a support rod 3 via pins; slide rails 4 are provided on both sides of the outer surface of the pusher plate 2, and sliders 5 are slidably connected to the slide rails 4, with the other end of the support rod 3 hinged to the sliders 5; a locking connector 11 is provided on the sliders 5, and a locking limiting device is provided on the back of the pusher plate 2. When the sliders 5 reach the designated position, the locking connector 11 locks and limits the movement with the locking limiting device.

[0017] The locking and limiting device includes a locking seat 12, a spring 13, and a telescopic pin 14; the locking seat 12 is fixed to the inner side of the slide 4 on the back of the pusher plate 2, and the telescopic pin 14 is positioned in the locking seat 12 by the spring 13; when the locking head 11 passes the telescopic pin 14, the telescopic pin 14 locks with the inner end face of the locking head 11.

[0018] The snap-fit ​​connector 11 has a frustum structure, and the telescopic pin 14 has a right-angled triangle cross section. When the telescopic pin 14 snaps into the snap-fit ​​connector 11, the large-diameter end face of the snap-fit ​​connector 11 contacts and limits the contact with the right-angled side of the telescopic pin 14.

[0019] The center of the snap-fit ​​connector 11 is connected to the slider 5 via a connecting rod 15. A guide head 16 is provided on the connecting rod 15. The guide head 16 has a frustum structure and its direction is opposite to that of the snap-fit ​​connector 11. The large diameter of the guide head 16 is equal to the large diameter end of the connecting rod 15. The guide head 16 has a sliding distance of 2 to 10 cm on the connecting rod 15.

[0020] The working process of the pusher plate clamping device of the vertical feeding shredder of this application is as follows: When the pusher plate 2 is opened, the support rod 3 drives the slider 5 to move upward on the slide rail 4, and at the same time drives the clamping joint 11 to move upward. When the clamping joint 11 passes the telescopic pin 14, the top of the telescopic pin 14 moves along the inclined plane of the frustum and retracts inward. After passing the clamping joint 11, as... Figure 3 As shown, the bottom surface of the frustum of the snap-fit ​​connector 11 engages with the right-angled edge of the telescopic pin 14, thus positioning the smoke pusher 2. When it is necessary to close the smoke pusher 2, continue to raise the smoke pusher 2, as shown. Figure 4 As shown, the large end face of the guide head 16 contacts the inclined surface of the telescopic pin 14. The guide head 16 moves forward, and at the same time, the telescopic pin 14 retracts. When the telescopic pin 14 contacts the inclined surface of the guide head 16, the large end face of the guide head 16 fits against the large end face of the snap-fit ​​connector 11. Then the push plate 2 is lowered. The telescopic pin 14 can only retract and extend along the inclined surface of the guide head 16 and the snap-fit ​​connector 11, and cannot snap into the snap-fit ​​connector 11. Therefore, the slider is successfully reset, and the closing action of the push plate 2 is completed.
