[0025] Reference Figures 1 to 3 As shown, the utility model discloses a cutter device with adjustable width. Specifically, the device includes a waste box 10, a mounting plate 20, a guide rod 30, a screw rod 40, a pitch-adjusting screw rod 50, a cylinder mounting plate 60, a cutter 70, a scraper 80, a cutter driving cylinder 90 and a scraper driving cylinder 100; a mounting plate 20 is respectively provided at both ends of the waste box 10, and the mounting plates 20 are fixedly connected to the two ends of the waste box 10, and the distance between the two mounting plates 20 is equivalent to the length of the waste box 10.
[0026] Two cylinder mounting plates 60 are also arranged between the two mounting plates 20. A screw rod 40 is arranged at the bottom of the mounting plate 20 and the cylinder mounting plate 60. The screw rod 40 passes through the mounting plate 20 and the cylinder mounting plate 60 arranged on the waste box 10. A screw nut is arranged at the connection between the screw rod 40 and the cylinder mounting plate 60, and an adjusting knob is also arranged at one end of the screw rod 40. The positions of the two groups of cylinder mounting plates 60 can be changed by turning the adjusting knob and with the cooperation of the screw nut.
[0027] Reference Figure 7A guide rod 30 is also provided on both sides of the screw rod 40. Both ends of the guide rod 30 are connected to the mounting plate 20, and the guide rod 30 also passes through the cylinder mounting plate 60, so that the guide rod 30 and the screw rod 40 are arranged in parallel. A pitch-adjusting screw rod 50 is provided above the screw rod 40. The pitch-adjusting screw rod 50 is connected between the two cylinder mounting plates 60, and the pitch-adjusting screw rod 50 and the screw rod 40 are also arranged in parallel. A pitch-adjusting screw nut 501 is provided at the connection between the pitch-adjusting screw rod 50 and the cylinder mounting plate 60, and a pitch-adjusting knob is provided on the pitch-adjusting screw rod 50. By turning the pitch-adjusting knob, the pitch-adjusting screw rod 50 can be rotated, and then the pitch-adjusting screw nut on the pitch-adjusting screw rod 50 can be moved.
[0028] A cutter drive cylinder 90 and a scraper drive cylinder 100 are arranged on one of the cylinder mounting plates 60, and the cutter drive cylinder 90 and the scraper drive cylinder 100 are arranged on both sides of the cylinder mounting plate. The cutter drive cylinder 90 is connected to the cutter 70, and the cutter 70 can be moved away from or close to the diaphragm under the drive of the cutter drive cylinder 90. The scraper drive cylinder 100 is connected to the scraper 80, and the scraper drive cylinder 100 can be driven to move the scraper 80 away from or close to the diaphragm.
[0029] Similarly, a cutter drive cylinder 90 and a scraper drive cylinder 100 are also provided on the other cylinder mounting plate 60, and the cutter drive cylinder 90 and the scraper drive cylinder 100 are provided on both sides of the cylinder mounting plate. The cutter drive cylinder 90 is connected to the cutter 70, and the cutter 70 can be moved away from or close to the diaphragm under the drive of the cutter drive cylinder 90. The scraper drive cylinder 100 is connected to the scraper 80, and the scraper 80 can be moved away from or close to the diaphragm under the drive of the scraper drive cylinder 100. The cutter 70 and the cutter drive cylinder 90 are connected through a mounting frame.
[0030] The cutter 70 , scraper 80 , cutter drive cylinder 90 and scraper drive cylinder 100 on the two cylinder mounting plates 60 are arranged symmetrically, which means that the cutter 70 is arranged on one side of the cylinder mounting plate 60 , and the scraper 80 is arranged on the other side of the cylinder mounting plate 60 .
[0031] Reference Figures 4 to 5 As shown, Figure 4 as well as Figure 5 The diagram is a structural diagram of a cutter 70 and a scraper 80 installed on a cylinder mounting plate 60. Specifically, the cutter 70 is a circular cutter and can rotate. Because a cutter device with an adjustable width is arranged below the material roll, the cutter 70 is driven by a cutter drive cylinder 90 to approach the material roll and contact the material roll. When the material roll rotates, the circular cutter 70 can cut the film on the material roll.
[0032] Reference Figure 6The scraper 80 is mounted on a scraper fixing seat 802, the scraper fixing seat 802 is connected to a cylinder connecting seat 803, and the cylinder connecting seat 803 is connected to a scraper driving cylinder 100. The scraper driving cylinder 100 can drive the cylinder connecting seat 803 to move so as to move the scraper 80 away from or close to the diaphragm. A fixing block 804 is provided on the side of the connection between the scraper 80 and the scraper fixing seat 802. In this embodiment, only the side of the scraper 80 used for scraping the diaphragm is not provided with a fixing block 804. The scraper 80 is fixedly mounted on the scraper fixing seat 802 by the fixing block 804.
[0033] The scraper fixing seat 802 is provided with protruding edges at both ends, and the edges are provided with adjustment holes 801, which are waist-shaped holes; correspondingly, the cylinder connecting seat 803 is provided with limiting holes 805 at both ends, which are circular holes. The adjustment holes 801 on the scraper fixing seat 802 correspond to the limiting holes 805 on the cylinder connecting seat 803. When the position of the scraper 80 is determined, a screw or the like can be inserted into the adjustment hole 801 and then inserted into the limiting hole 805 to fix the position of the scraper 80.
[0034] The scraper fixing seat 802 and the cylinder connecting seat 803 are in sliding connection, that is, when the cylinder connecting seat 803 is connected to the scraper driving cylinder 100, the scraper fixing seat 802 can move along the width direction of the diaphragm on the cylinder connecting seat 803. Specifically, in this embodiment, the scraper fixing seat 802 and the cylinder connecting seat 803 are slidably connected in the following manner: a protruding block is provided at the bottom of the scraper fixing seat 802, and a groove is provided at the top of the cylinder connecting seat 803. The protruding block on the scraper fixing seat 802 and the groove on the cylinder connecting seat 803 can be meshed, so that the scraper fixing seat 802 can slide on the cylinder connecting seat 803. In other embodiments, it may also be that: a groove is provided at the bottom of the scraper fixing seat 802, and a protruding block is provided at the top of the cylinder connecting seat 803, and the groove on the scraper fixing seat 802 can engage with the protruding block on the cylinder connecting seat 803, so that the scraper fixing seat 802 can slide on the cylinder connecting seat 803.
[0035] When the position of the scraper 80 needs to be adjusted, the scraper fixing seat 802 can slide on the cylinder connecting seat 803, thereby achieving the purpose of scraping the membrane at different positions. After the position of the scraper 80 is adjusted, the position of the scraper 80 is fixed through the adjustment hole 801 and the limit hole 805 to ensure that after the cutter 70 cuts the membrane, the scraper 80 can completely scrape the membrane attached to the steel roller.
[0036] In this solution, the distance adjusting knob is controlled to drive the distance adjusting screw 50 to move, and then the distance adjusting nut 501 on the distance adjusting screw 50 is moved, so that the relative distance between the two sets of cutters 70 is changed. By changing the distance between the two sets of cutters 70, membranes of different widths can be cut.
[0037] The screw nut on the screw 40 can be rotated by controlling the adjustment knob. Since the screw 40 is connected to two sets of cylinder mounting plates 60, the position of the two sets of cylinder mounting plates 60 can be changed by controlling the adjustment knob. When the diaphragm is not at the center of the roller surface, or the distances to be cut off the edge of the diaphragm are inconsistent, the relative position of the screw nut on the screw 40 is adjusted to move the relative center of the entire cutter 70, scraper 80 and cylinder mounting plate 60 to one side, thereby changing the center position of the diaphragm. The guide rod 30 is connected to the two sets of cylinder mounting plates 60 through linear bearings. The screw nut can be separated or closed by rotating the screw 40, thereby adjusting the relative position of the two sets of scrapers 80.
[0038] The above is a specific description of the preferred implementation of the utility model, but the invention of the utility model is not limited to the described embodiments. Technical personnel familiar with the field can also make various equivalent deformations or substitutions without violating the spirit of the utility model. These equivalent deformations or substitutions are all included in the scope defined by the claims of this application.
