Description

Technical Field

[0001] This utility model relates to the field of strip cutting technology, specifically to a continuous strip cutting device. Background Technology

[0002] Carrier tape refers to a strip-shaped product used in the field of electronic packaging. It has a specific thickness and has holes for holding electronic components and positioning holes for indexing and positioning distributed evenly along its length. In the production line, it is also often called material tape. During its processing, it needs to be slit.

[0003] A search revealed that the Chinese patent "An Electronic Carrier Tape Slitting Device" (authorization announcement number CN220548338U) includes a mounting base, on which a guide assembly and a slitting assembly are mounted. The guide assembly includes a guide seat and a guide roller. A guide groove is provided on the guide seat, and a positioning strip is installed on one side of the guide groove. A positioning spring is installed between the positioning strip and the guide groove. The two sides of the electronic carrier tape respectively contact the other side of the guide groove and the positioning strip. The positioning strip and the positioning spring limit the two sides of the electronic carrier tape to zero gap, ensuring that the electronic carrier tape will not swing left and right during the conveying process, thereby ensuring the guiding accuracy.

[0004] However, the above method has the following drawbacks in actual use: during the guiding process, the positioning strip and the side of the carrier belt undergo hard sliding friction, which generates continuous frictional resistance, which not only increases the driving load, but also easily damages the side of the carrier belt and affects the processing effect.

[0005] Based on this, the present invention designs a continuous strip cutting device to solve the above problems. Utility Model Content

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a continuous strip cutting device.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A continuous strip cutting device includes a frame, on which a cutting mechanism is provided, and two limiting components. The limiting components are disposed on the frame and are used to limit and guide the strip during movement. Each limiting component includes an air bladder ring and a transmission belt. The outer side of the air bladder ring is provided with anti-slip texture, and the air bladder ring is fixedly sleeved on the outer side of the transmission belt.

[0009] Furthermore, two rubber rings are fixedly sleeved on the outer side of the airbag ring, and the two rubber rings are arranged symmetrically above and below the central area of ​​the airbag ring.

[0010] Furthermore, a pressure detector is provided on the airbag ring, with one end of the pressure detector passing through and extending to the outside of the drive belt.

[0011] Furthermore, the airbag ring is provided with an air injection pipe that passes through the transmission belt, and a valve is provided on the outside of the air injection pipe.

[0012] Furthermore, both of the rubber rings have a chamfered edge on their opposite sides.

[0013] Furthermore, a mounting box is provided on the outer side of the transmission belt, and two rotating shafts located inside the transmission belt are rotatably connected inside the mounting box.

[0014] Furthermore, a support platform is provided above the frame, and the mounting box is detachably mounted onto the support platform.

[0015] Furthermore, the slitting mechanism includes a pressure roller and a drive roller, and a set of annular blades that contact the outer side of the pressure roller are provided on the outer side of the drive roller.

[0016] Compared with the prior art, the advantages of this utility model are as follows:

[0017] 1. By setting up an airbag ring in conjunction with a transmission belt, the airbag ring can resist and limit the side of the belt while moving with the belt in real time, thereby reducing frictional resistance, reducing drive load, and reducing belt damage.

[0018] 2. By setting a pressure detector, the air pressure during the material belt limiting process can be monitored in real time. When the air pressure deviates from the preset value, the user can be notified in time and correct the deviation to ensure the cutting accuracy of the material belt.

[0019] 3. By setting up an air injection pipe and a detachable mounting box, the air injection volume can be changed to finely adjust the limiting range of the airbag ring, and the mounting box can be moved to greatly adjust the limiting range of the airbag ring, so as to meet the limiting guidance requirements when cutting different material strips.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0028] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0029] In some embodiments, please refer to the accompanying drawings. Figures 1-4 A continuous strip cutting device includes a frame 100, on which a cutting mechanism is provided, and two limiting components 200. The limiting components 200 are disposed on the frame 100 and are used to limit and guide the strip during the movement. Each limiting component 200 includes an airbag ring 210 and a transmission belt 220. The outer side of the airbag ring 210 is provided with anti-slip texture, and the airbag ring 210 is fixedly sleeved on the outer side of the transmission belt 220.

[0030] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, two rubber rings 211 are fixedly sleeved on the outer side of the airbag ring 210, and the two rubber rings 211 are arranged symmetrically up and down along the central area of ​​the airbag ring 210.

[0031] By using the airbag ring 210 to fit against the side of the material belt, a flexible limiting effect is achieved. During the material belt slitting and conveying process, the airbag ring 210 can follow the movement of the material belt, so that the transmission belt 220 is continuously driven, reducing the frictional resistance generated when the material belt is limited. Combined with the symmetrical rubber rings 211, the upper and lower sides of the material belt are blocked and limited, reducing the fluctuation of the material belt and completing the limited conveying of the material belt. Then, the limited material belt is slitting through the slitting mechanism on the frame 100.

[0032] It should be noted that during the slitting operation, a winding mechanism and an unwinding mechanism are respectively set on both sides of the material strip slitting area, and the entire slitting operation is carried out continuously.

[0033] The rubber ring 211 can be installed in a position that corresponds to the thickness of the material strip in this batch, and a slight fit is sufficient.

[0034] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, a pressure detector 212 is provided on the airbag ring 210, and one end of the pressure detector 212 passes through and extends to the outside of the transmission belt 220.

[0035] The pressure detector 212 is used to monitor the pressure inside the airbag ring 210 in real time. When the air pressure deviates from the preset value, it can be corrected by the correction device on the cutting mechanism, or the user can manually correct it by stopping the machine.

[0036] It should be noted that the pressure detector 212 is a tire pressure detector commonly used in the prior art. This device is a mature technology and is small in size, making it suitable for the processing operations of this application.

[0037] In some embodiments, such as Figure 2 , Figure 3 and Figure 4 As shown, in a preferred embodiment of the present invention, the airbag ring 210 is provided with an air injection pipe that passes through the transmission belt 220, and a valve is provided on the outside of the air injection pipe.

[0038] Before the material belt is conveyed, the corresponding gas can be introduced into the air bag ring 210 along the air injection pipe according to the position of the material belt, so as to ensure that the air bag ring 210 and the material belt are in contact and fit together without excessive compression, thereby reducing the occurrence of material belt curling while ensuring the limiting effect.

[0039] It should be noted that this air injection method can be finely adjusted according to the position of the material belt side. During the air injection process, the user can use an external three-way pipe to connect to the two air injection pipes respectively for synchronous air injection. By utilizing the influence of air pressure balance, the gas content in the two airbag rings 210 is the same, ensuring the stability during symmetrical positioning.

[0040] In some embodiments, such as Figure 4 As shown, in a preferred embodiment of the present invention, the two rubber rings 211 are both chamfered on opposite sides.

[0041] This makes it easier to insert the side of the material strip during the preparation work before slitting the strip.

[0042] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, in a preferred embodiment of the present invention, a mounting box 221 is provided on the outer side of the transmission belt 220, and two rotating shafts located inside the transmission belt 220 are rotatably connected inside the mounting box 221.

[0043] The mounting box 221 is used to support the rotating shaft, and the rotating shaft ensures the stability of the drive belt 220 following the driven belt.

[0044] In some embodiments, such as Figure 1 As shown, in a preferred embodiment of the present invention, a support platform is provided above the frame 100, and the mounting box 221 is detachably mounted on the support platform.

[0045] A support platform is used to support the mounting box 221, and the user can change the installation position of the mounting box 221 according to the different widths of the material, thereby changing the limiting area.

[0046] In some embodiments, such as Figure 1 As shown, in a preferred embodiment of the present invention, the slitting mechanism includes a pressure roller and a drive roller, and a set of annular blades that contact the outer side of the drive roller are provided on the outer side of the pressure roller.

[0047] The pressure roller made of ABS material is connected to the annular blade to reduce wear. When the pressure roller receives the material strip, the annular blade is used to complete the slitting operation.

[0048] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
