Description

Technical Field

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

[0002] In the production and processing of rubber strips, the whole rubber strip usually needs to be cut into a preset length according to the requirements. That is, the extruded long rubber strip needs to be cut into rubber strips of different specifications and lengths. Existing rubber strip cutting devices usually directly punch the rubber strip. However, because the rubber strip is relatively soft, it is difficult to guarantee the length accuracy of the rubber strip segment and the flatness and perpendicularity requirements of the end face, which affects its factory quality and subsequent reprocessing. Utility Model Content

[0003] To address the technical problems mentioned in the background section, this utility model provides a soft rubber strip cutting device.

[0004] The technical solution of this utility model is as follows: A soft rubber strip cutting device includes a cutting frame and a clamping mechanism and a cutting mechanism provided thereon. The clamping mechanism can clamp the rubber strip, and the cutting mechanism can cut the rubber strip.

[0005] As the core technical concept of this utility model, the clamping mechanism includes a fixed block and a movable block elastically slidably disposed on one side thereof, and the direction of the elastic force on the movable block is opposite to that of the fixed block. A through groove is provided on the adjacent side of the fixed block and / or the movable block to accommodate the passage of the adhesive strip. The cutting mechanism includes a telescopic drive motor and a cutting blade driven thereon. A cutting groove is provided on the fixed block and / or the movable block to accommodate the cutting blade cutting into the through groove. The cutting mechanism also includes a clamping mechanism driven on the telescopic drive motor, which is configured to drive the movable block toward the fixed block. Based on the above structure, the rubber strip can pass through the through groove. The telescopic drive can drive the clamping mechanism to move the movable block, so that the fixed block and the movable block can cooperate to clamp the rubber strip in the through groove. With the continued action of the telescopic drive, the cutting blade can be driven from the cutting groove into the through groove to cut the rubber strip, thus ensuring the convenience of rubber strip cutting. At the same time, the through groove, together with the fixed block and the movable block, effectively prevents deformation of the cutting position during rubber strip cutting, ensuring the length of the rubber strip segment and the flatness and perpendicularity requirements of the cutting end face.

[0006] In order to improve the response speed of the telescopic drive motor and thus its cutting speed, the telescopic drive motor of the aforementioned soft rubber strip cutting device is equipped with a cylinder.

[0007] As described above, the soft rubber strip cutting device includes a blade holder and a blade mounted on the blade holder. To improve the cutting effect of the blade on the rubber strip, the angle between the cutting edge of the blade and its cutting direction is not 90°, so that the cutting edge of the blade can be inclined to complete the cutting of the rubber strip.

[0008] As a further preferred embodiment, to facilitate timely replacement of the blade, one side of the blade holder is provided with a placement slot that can accommodate the blade, and the blade is detachably fixed in the placement slot by a pressure block.

[0009] As described above, the soft rubber strip cutting device includes a clamping mechanism, which comprises a clamping frame and a clamping wheel mounted thereon. The clamping frame is configured to move so that the clamping wheel can push the movable block toward the fixed block, thereby ensuring the operation of the telescopic drive and enabling the clamping wheel of the clamping mechanism to push the movable block more smoothly.

[0010] In a preferred embodiment, to reduce the impact on the movable block when the clamping mechanism pushes it to move and to prevent rigid damage to the movable block, the clamping wheel is elastically mounted on the clamping frame.

[0011] The beneficial effects of this utility model are as follows: This utility model is a soft rubber strip cutting device. The rubber strip can pass through the through groove. The action of the telescopic drive can drive the clamping mechanism to move the movable block, so that the fixed block and the movable block can cooperate to clamp the rubber strip in the through groove. Through the continued action of the telescopic drive, the cutting blade can be driven to cut into the through groove from the cutting groove, thereby cutting the rubber strip. This ensures the convenience of rubber strip cutting. At the same time, the through groove, together with the fixed block and the movable block, effectively prevents deformation of the cutting position during rubber strip cutting, ensuring the length of the rubber strip segment and the flatness and perpendicularity requirements of the cutting end face.

[0014] Exemplary embodiments of this disclosure will now be described in more detail with reference to the accompanying drawings.

[0015] Example This embodiment provides a soft rubber strip cutting device, see [link]. Figure 1 The device includes a cutting frame 1 and a clamping mechanism 2 and a cutting mechanism 3 installed on it. The clamping mechanism 2 can clamp the adhesive strip, and the cutting mechanism 3 can cut the adhesive strip. The structure of the cutting device (the above-mentioned soft adhesive strip cutting device) will be described in detail below with reference to the accompanying drawings.

[0016] In this embodiment, combined with Figure 2 The cutting frame 1 includes a horizontally arranged base plate 11 and a vertical plate 12 arranged on one side of it. A fixing plate 13 is horizontally arranged on the upper part of the vertical plate 12 near the base plate 11. The clamping mechanism 2 is arranged on the base plate 11, and the cutting mechanism 3 is arranged on the fixing plate 13 and is arranged vertically opposite to the clamping mechanism 2.

[0017] Combination Figure 4 First, regarding the structure of the cutting mechanism 3, it includes a telescopic drive motor vertically mounted on the upper side of the fixed plate 13. Its transmission end passes downward through the fixed plate 13 and is equipped with a cutting blade. The action of the telescopic drive motor can drive the cutting blade to move downward to complete the cutting of the adhesive strip on the clamping mechanism 2.

[0018] In a preferred embodiment of this invention, the cutting blade includes a blade holder 32 and a blade 33 disposed on the blade holder 32. To improve the cutting effect of the blade 33 on the rubber strip, the angle between the cutting edge of the blade 33 and its cutting direction is not 90°, so that the cutting edge of the blade 33 can be inclined to complete the cutting of the rubber strip.

[0019] Specifically, the blade holder 32 is a "7"-shaped structure composed of a first horizontal block and a first vertical block. The middle part of the first horizontal block is fixed to the transmission end of the telescopic drive motor, and the blade 33 is obliquely fixed between the first horizontal block and the first vertical block.

[0020] As a further preferred embodiment, to facilitate timely replacement of the blade 33, a placement groove is provided on one side of the tool holder 32 to accommodate the blade 33. The blade 33 is detachably fixed in the placement groove by a pressure block 34, and the cutting edge is exposed by a first horizontal block and a first vertical block.

[0021] Preferably, in order to improve the response speed of the telescopic drive and thus its cutting speed, the telescopic drive uses a cylinder 31.

[0022] Combination Figure 3 Regarding the structure of the clamping mechanism 2, it includes a fixed block 21 mounted on the base plate 11 and a movable block 22 elastically slidably mounted on one side of the fixed block 21. The direction of the elastic force on the movable block 22 is opposite to that on the fixed block 21. The adjacent sides of the fixed block 21 and / or the movable block 22 are provided with through grooves that can accommodate the passage of the adhesive strip. The fixed block 21 and / or the movable block 22 are provided with cutting grooves that can accommodate the cutting blade 33 cutting into the through grooves. The cutting mechanism 3 also includes a clamping mechanism 35 driven on the telescopic drive mechanism, which is configured to drive the movable block 22 toward the fixed block 21. 1. Sliding: Based on the above structure, the adhesive strip can pass through the through groove. The telescopic drive can drive the clamping mechanism 35 to move the movable block 22, so that the fixed block 21 and the movable block 22 can cooperate to clamp the adhesive strip in the through groove. With the continued action of the telescopic drive, the cutting blade can be driven to cut into the through groove from the cutting groove, thereby cutting the adhesive strip. This ensures the convenience of cutting the adhesive strip. At the same time, the through groove, together with the fixed block 21 and the movable block 22, effectively prevents deformation of the cutting position during the cutting of the adhesive strip, ensuring the length of the adhesive strip segment and the flatness and perpendicularity requirements of the cutting end face.

[0023] Specifically, the fixed block 21 is an "L"-shaped structure composed of a second horizontal block and a second vertical block. The second horizontal block is fixed to the upper middle part of the base plate 11. A guide shaft 23 is provided horizontally on the inner side of the second vertical block. The movable block 22 has an opening in the middle, and a sliding sleeve 24 is fixed in the opening. The sliding sleeve 24 is slidably sleeved on the guide shaft 23, and the lower side of the movable block 22 is slidably attached to the upper side of the second horizontal block. A spring is also provided between the sliding sleeve 24 and the second vertical block. A limiting block 26 that can restrict the movable block 22 is provided on the side of the second horizontal block away from the second vertical block. Based on this structure, in a natural state, the sliding sleeve 24 can be moved in the direction away from the second vertical block by the elastic action of the spring and press against the limiting block 26.

[0024] Furthermore, the upper side of the second vertical block is provided with a through groove, and the upper part of the movable block 22 near the second vertical block is also provided with a through groove. The movable block 22 is configured to slide towards the second vertical block under the pressing action of the pressing mechanism 35, so that the through groove on it can close with the through groove on the second vertical block to form a channel that can accommodate the rubber strip to pass through. The rubber strip can be squeezed and fixed in the channel to achieve clamping and fixing.

[0025] Furthermore, a wedge block 25 is provided on the upper part of the side of the movable block 22 opposite to the second vertical block, which is configured to cooperate with the clamping mechanism 35 to push the movable block 22 to move.

[0026] In this embodiment, the structure of the clamping mechanism 35 includes a clamping frame 351 disposed on one side of the knife holder 32, and a clamping wheel 352 disposed on the clamping frame 351. The movement of the clamping frame 351 is configured to push the movable block 22 toward the fixed block 21 through the clamping wheel 352, so as to ensure that the operation of the telescopic drive can be completed more smoothly by the clamping wheel 352 of the clamping mechanism 35.

[0027] Specifically, the clamping frame 351 has a "7" shaped structure, with its horizontal portion having its outer end fixed to the knife holder 32, and the clamping wheel 352 located at the lower end of the vertical portion of the clamping frame 351.

[0028] As a preferred embodiment, in order to reduce the impact on the movable block 22 when the clamping mechanism 35 pushes the movable block 22 to move and to prevent the movable block 22 from being rigidly damaged, the clamping wheel 352 is elastically arranged on the clamping frame 351.

[0029] Specifically, the lower end of the vertical portion of the clamping frame 351 has a horizontally open strip-shaped opening. The length direction of the strip-shaped opening is consistent with the sliding direction of the movable block 22. The clamping wheel 352 is rotatably sleeved on a wheel axle, and the end of the wheel axle is placed inside the strip-shaped opening. A limiting shaft is also inserted on one side of the lower end of the vertical portion of the clamping frame 351 along the length direction of the strip-shaped opening. The limiting shaft extends from the outside of the clamping frame 351 into the strip-shaped opening and passes through the wheel axle. Based on this structure, the limiting shaft can slide within the strip-shaped opening, that is, slide along the length direction of the strip-shaped opening. The clamping wheel 352 can rotate around the wheel axle. The outer ring of the portion of the limiting shaft located between the inner wall of the strip-shaped opening and the wheel axle is provided with a spring, and the direction of the elastic force of the spring on the wheel axle is consistent with the clamping direction of the sliding block.
