Description

Technical Field

[0001] The utility model belongs to the field of sealing strip cutting, in particular to a sealing strip cutting machine. Background Art

[0002] Sealing strips are products that seal something and make it difficult to open, and have the functions of shock absorption, waterproofing, sound insulation, heat insulation, dust prevention, and fixing. The cut coils used to produce sealing parts such as foam sealing strips need to be cut into strips of required width by a cutting machine.

[0003] When the sealing strip is cut, the lower pressure plate must first be used to directly press the cut coil, and then the cutting knife is used to complete the cutting of the coil. Although this can also complete the cutting of the sealing strip well, it cannot ensure that the lower pressure plate can completely press the cut coil, resulting in poor quality of the cut sealing strip. In addition, the cut sealing strip cannot be well unloaded onto the unloading conveyor. Utility Model Content

[0017] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0018] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0019] For the convenience of explanation, only the parts related to the embodiment of the present utility model are shown.

[0020] Combination Figure 1-5 As shown, the sealing strip cutting machine includes a cutting table 1, on which a discharge wheel 2, a feeding mechanism, a cutting mechanism and a unloading mechanism are sequentially arranged, and the cutting mechanism includes a transverse plate 3 and a cutting plate 4 installed at the upper and lower positions of the cutting table 1, and a cutting cylinder 5 is arranged on the transverse plate 3, and the driving shaft of the cutting cylinder 5 is connected to a driving plate 6, and a plurality of connecting rods 7 are inserted from the top of the driving plate 6 and a stopper 8 is formed on the top of the connecting rod 7, and a lower pressure plate 9 arranged toward the cutting plate 4 is provided at the bottom of all the connecting rods 7, and a spring 10 is provided on each connecting rod 7 and between the lower pressure plate 9 and the driving plate 6, and a cutting knife 11 is provided on the outer side of the driving plate 6, and the cutting knife 11 is staggered with the cutting plate 4.

[0021] When the cutting machine is used to process and manufacture sealing strips, the coil is first installed on the unwinding wheel according to corresponding requirements, and the ends of the coil pass through the feeding mechanism in sequence, and the coil is continuously moved toward the cutting mechanism through the feeding mechanism. During the movement, the coil is cut into sealing strips of the same specifications through the cutting mechanism, and the sealing strips fall onto the unloading mechanism for unloading and collection.

[0022] When the cutting mechanism is used to cut the coil to make a sealing strip, the front end of the coil is conveyed and located on the cutting plate. The cutting cylinder drives the driving plate to move downward until the lower pressure plate contacts the coil. The cutting cylinder continues to drive the driving plate to move downward for a short distance. In this process, all springs are compressed. Under the preload of the springs, the cut part of the coil is clamped by the cutting plate and the lower pressure plate. At the same time, the cutting knife cuts the coil located outside the cutting plate into a sealing strip, and the sealing strip falls onto the unloading mechanism for unloading. The driving plate is reset, and the front end of the coil continues to be conveyed forward the same distance, waiting for the next cutting. The cutting knife has an inclined blade, which makes it easier to cut the coil.

[0023] As a preferred structure, Figure 1-4 The surface of the cutting table 1 is provided with a blanking opening 13 corresponding to the cutting knife 11, and the blanking mechanism includes a base plate 14 installed on the blanking opening 13, a pair of slides 15 are provided on the base plate 14, a support seat 16 is provided between the two slides 15, the support seat is located on the base plate, a blanking plate 17 is provided on the support seat 16, a blanking frame 18 is provided on the two slides 15 for sliding together, and the front plate of the blanking frame 18 is in contact with the blanking plate 17, and the cutting table 1 is also provided with a blanking cylinder 19 for driving the blanking frame 18 to move, a blanking conveying platform 20 is provided inside and outward of the cutting table 1, and the blanking opening 13 is located above the blanking conveying platform 20.

[0024] The cut sealing strip falls on the unloading plate, and the sealing strip is located in the unloading frame. Then the unloading cylinder drives the unloading frame to move backward, and the unloading frame moves backward as a whole. The front plate of the unloading frame pushes the sealing strip backward and toward the unloading port, until the sealing strip falls from the unloading port onto the unloading conveyor table, and the sealing strip is unloaded and collected via the unloading conveyor table. At the same time, the unloading frame is reset to prepare to push the next sealing strip to realize its unloading.

[0025] The blanking plate 17 is provided with a plurality of grooves 21 along the length direction, and the front plate of the blanking frame 18 is provided with a tooth block 22 corresponding to each groove 21, and the tooth block 22 is located in each groove 21. The blanking plate is provided with a plurality of grooves, so that the contact area between the sealing strip and the blanking plate can be reduced, so that when the front plate of the blanking frame pushes the sealing strip toward the blanking port for blanking, the friction between the two can be reduced by providing the grooves. At the same time, the tooth blocks on the bottom surface of the front plate of the blanking frame are located in the grooves one by one, so that the front plate of the blanking frame can better push the sealing strip to perform blanking.

[0026] Further as a preferred structure, Figure 3 The feeding mechanism includes a pair of mounting wheels 23 and a plurality of guide wheels 24 rotatably mounted above the cutting table 1, a matching belt 25 is sleeved between the two mounting wheels 23, a driving motor (blocked in the figure) for driving any mounting wheel to rotate is also provided in the cutting table 1, a pair of adjusting wheels 26 are also rotatably provided above the cutting table 1, one of the adjusting wheels is set toward the belt, and the other adjusting wheel is set toward one of the guide wheels, two pairs of sliders 27 are slidably provided above the cutting table 1, the adjusting wheels 26 are rotatably mounted between the same pair of sliders 27, and an adjusting cylinder 28 for driving the slider to slide up and down is also provided above the cutting table 1.

[0027] In this structure, both adjusting wheels can be moved up and down by adjusting cylinders to achieve their adjustment function. When the front end of the coil is to pass through the feeding mechanism, the two adjusting cylinders first simultaneously drive the slider to move upward a short distance. At this time, the front end of the coil is passed around the guide wheel in turn and placed on the corresponding position of the belt. At this time, both adjusting wheels are located above the coil. All adjusting cylinders work at the same time, the sliders of the same pair move downward, and the two adjusting wheels press the coil. Then the drive motor drives the corresponding mounting wheel to rotate, the belt rotates, and under the downward pressure of the adjusting wheel, the coil moves toward the cutting mechanism.

[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the present utility model.
