A rotary cutting machine

Abstract

This utility model discloses a rotary cutting machine in the field of cutting machine technology, including a base. A groove is formed on the top surface of the base, and a one-way transmission rod is rotatably arranged within the groove. A pusher is threaded onto the one-way transmission rod. A support frame is fixedly installed on the top of the base, and an electric pusher is fixedly installed on the inner top wall of the support frame. This utility model uses a cutting head to drive a transmission toothed plate downwards to engage with the one-way transmission rod, thus keeping the one-way transmission rod stationary. When the cutting head moves upwards, it drives the transmission toothed plate upwards, which in turn drives the one-way transmission rod to rotate, causing the pusher to push the roll material equidistantly below the cutting head. Therefore, equidistant cutting of the roll material is more convenient. When the cutting head moves downwards, it drives a fixed plate, a movable plate, and a rubber plate to move downwards simultaneously. At this time, the rubber plate contacts the roll material, thereby pressing and fixing the roll material to reduce the possibility of positional displacement during cutting.

Description

Technical Field

[0001] This utility model relates to the field of cutting machine technology, and in particular to a rotary cutting machine. Background Technology

[0002] Cutting machines are used for dividing and cutting sheet materials in various industries. They do not require any molds; they are controlled by system software and then directly cut the products. As long as the corresponding parameters are set on the operating platform, the computer transmits the corresponding instructions to the cutting machine; the cutting machine then quickly cuts according to the received design drawings. It has a high degree of automation and is easy to operate, making it a cutting device used in many industries.

[0003] Existing cutting machines use electric push rods to push the roll material and another electric push rod to drive the cutting head to cut the roll material. To achieve equidistant cuts, the two electric push rods need to be programmed to operate alternately, making equidistant cutting of the roll material cumbersome. Therefore, we propose a rotary cutting machine to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide a rotary cutting machine that can solve the problem that some existing cutting machines push the roll material with an electric push rod and then push the cutting head to cut the roll material with another electric push rod. In order to cut the roll material at equal intervals, it is necessary to set the two electric push rods to operate alternately, which makes it more troublesome to cut the roll material at equal intervals.

[0006] To solve the above-mentioned technical problems, this utility model provides a rotary cutting machine, which adopts the following technical solution: it includes a base, the top surface of the base is provided with a sliding groove, a one-way transmission rod is rotatably arranged in the sliding groove, a pusher is threaded on the one-way transmission rod, a support frame is fixedly arranged on the top of the base, an electric push rod is fixedly arranged on the inner top wall of the support frame, a cutting head is fixedly arranged at the extended end of the electric push rod, two transmission tooth plates are symmetrically arranged on the outer wall of the cutting head, the transmission tooth plates engage with the one-way transmission rod after moving down, and a pressing member is arranged on the side wall of the cutting head.

[0007] By adopting the above technical solution, the roll material is first placed on the pusher, and then the electric pusher is started to push the cutting head to move up and down. As the cutting head moves down, the roll material is cut. At the same time, the pressing component presses and fixes the roll material to reduce the possibility of the roll material shifting during cutting and affecting the cutting process.

[0008] Optionally, a side plate is fixedly provided on the top surface of the base, and two inclined grooves are symmetrically opened on the side of the side plate facing the pusher.

[0009] By adopting the above technical solution, when the pusher plate moves toward the side plate, the inclined groove facilitates the control of the opening and closing of the pusher component.

[0010] Optionally, the one-way transmission rod includes a screw, a one-way bearing, and a gear. The screw is rotatably mounted in a sliding groove, the one-way bearing is fixedly sleeved on the screw, and the gear is fixedly sleeved on the one-way bearing. The gear meshes with a transmission gear plate.

[0011] By adopting the above technical solution, when the transmission gear plate moves down, it drives the gear and the one-way bearing to rotate. At this time, the one-way bearing is in the unlocked state. Therefore, the outer ring of the one-way bearing rotates with the gear, while its inner ring and the screw remain stationary.

[0012] Optionally, the pusher includes a horizontal plate and two movable blocks. The two movable blocks are symmetrically arranged on the bottom surface of the horizontal plate. The two movable blocks are inserted into the sliding groove and threaded onto the screw. Two horizontal grooves are opened on the front side of the horizontal plate, and clamping plates are movably arranged in the two horizontal grooves.

[0013] By adopting the above technical solution, when the screw rotates, it causes the movable block to move along the inner wall of the slide groove, and then the movable block drives the horizontal plate to move, and the horizontal plate pushes the roll material to move.

[0014] Optionally, a round rod is fixedly provided at one end of the clamping plate facing the horizontal plate. The round rod is connected to the inner wall of the horizontal groove by a first spring. The end of the round rod away from the clamping plate extends out of the horizontal plate and slides in cooperation with the inner wall of the inclined groove.

[0015] By adopting the above technical solution, when the round rod separates from the inclined groove, the first spring pulls the round rod and the clamping plate back to their original positions, thereby facilitating the clamping and fixing of the roll material through the clamping plate.

[0016] Optionally, the support frame is U-shaped, with two vertical grooves symmetrically formed on the inner sidewall of the support frame, and a cutting groove is formed on the top surface of the base, which is below the cutting head.

[0017] By adopting the above technical solution, this solution facilitates the installation of the electric push rod and the cutting head through the support frame, and facilitates the downward movement of the cutting head through the electric push rod to cooperate with the cutting groove to cut the roll material.

[0018] Optionally, the transmission tooth plate is L-shaped, with one end of the transmission tooth plate fixedly connected to the outer wall of the cutting head, and the other end of the transmission tooth plate inserted into the vertical groove and slidingly engaged with the inner wall of the vertical groove.

[0019] By adopting the above technical solution, this solution drives the transmission toothed plate to move synchronously when the cutting head moves, and increases the stability of the transmission toothed plate when it moves through the vertical groove.

[0020] Optionally, the pressing component includes a fixed plate, a movable plate, and a rubber plate. The fixed plate is fixedly disposed on the side wall of the cutting head, the movable plate is movably inserted into the fixed plate, the lower end of the movable plate passes through the fixed plate and is fixedly connected to the rubber plate, and the rubber plate is connected to the fixed plate by a second spring.

[0021] By adopting the above technical solution, when the cutting head moves down, it drives the fixed plate, the movable plate and the rubber plate to move down synchronously. At this time, the rubber plate comes into contact with the roll material, thereby pressing and fixing the roll material through the rubber plate.

[0022] In summary, this utility model has at least one of the following beneficial effects:

[0023] The cutting head drives the transmission tooth plate to move down and engage with the one-way transmission rod, thus keeping the one-way transmission rod stationary. When the cutting head moves up, it drives the transmission tooth plate to move up. At this time, the transmission tooth plate drives the one-way transmission rod to rotate, thus causing the pusher to push the roll material to move equidistantly below the cutting head. Therefore, it is more convenient to cut the roll material at equidistant intervals.

[0024] When the cutting head moves down, it causes the fixed plate, the movable plate and the rubber plate to move down synchronously. At this time, the rubber plate comes into contact with the roll material, thereby pressing and fixing the roll material to reduce the possibility of the roll material shifting when it is cut.

Detailed Implementation

[0030] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.

[0031] Example 1, refer to Figures 1-3 In this embodiment, to address the problem that some existing cutting machines use an electric pusher to push the roll material and another electric pusher to drive the cutting head to cut the roll material, requiring alternating operation commands for the two electric pushers to achieve equidistant cutting, which is cumbersome, this invention discloses a rotary cutting machine.

[0032] Includes a base 1, with a groove 2 on the top surface of the base 1. A one-way transmission rod 3 is rotatably installed in the groove 2. A pusher 4 is threaded onto the one-way transmission rod 3. When the one-way transmission rod 3 rotates, it is easy to control the movement of the pusher 4 and push the roll material.

[0033] A support frame 5 is fixedly installed on the top of the base 1. An electric push rod 6 is fixedly installed on the inner top wall of the support frame 5. A cutting head 7 is fixedly installed at the extended end of the electric push rod 6. The support frame 5 is U-shaped. Two vertical grooves 51 are symmetrically opened on the inner side wall of the support frame 5. A cutting groove 13 is opened on the top surface of the base 1. The cutting groove 13 is below the cutting head 7. The support frame 5 facilitates the installation of the electric push rod 6 and the cutting head 7. The electric push rod 6 facilitates the downward movement of the cutting head 7 and its cooperation with the cutting groove 13 to cut the roll material.

[0034] Two transmission gear plates 8 are symmetrically arranged on the outer wall of the cutting head 7. After the transmission gear plates 8 move down, they mesh with the one-way transmission rod 3. The one-way transmission rod 3 includes a screw 31, a one-way bearing 32, and a gear 33. The screw 31 is rotatably arranged in the slide groove 2. The one-way bearing 32 is fixedly sleeved on the screw 31, and the gear 33 is fixedly sleeved on the one-way bearing 32. The gear 33 meshes with the transmission gear plate 8. When the transmission gear plate 8 moves down, it drives the gear 33 and the one-way bearing 32 to rotate. At this time, the one-way bearing 32 is in an unlocked state. Therefore, the outer ring of the one-way bearing 32 rotates with the gear 33, while its inner ring remains stationary with the screw 31. When the transmission gear plate 8 moves up, it drives the gear 33 and the one-way bearing 32 to rotate. At this time, the one-way bearing 32 is in a locked state. Therefore, the outer ring of the one-way bearing 32 drives the inner ring and the screw 31 to rotate. As the screw 31 rotates, it is easy to control the movement of the pusher 4 to facilitate the feeding of the roll material.

[0035] The transmission tooth plate 8 is L-shaped. One end of the transmission tooth plate 8 is fixedly connected to the outer wall of the cutting head 7, and the other end of the transmission tooth plate 8 is inserted into the vertical groove 51 and slides in cooperation with the inner wall of the vertical groove 51. When the cutting head 7 moves, it drives the transmission tooth plate 8 to move synchronously, and the vertical groove 51 increases the stability of the transmission tooth plate 8 when it moves. When the transmission tooth plate 8 moves, it is easy to drive the gear 33 to rotate.

[0036] The side wall of the cutting head 7 is provided with a pressing member 9. By activating the electric push rod 6, the cutting head 7 is pushed to move up and down reciprocally. As the cutting head 7 moves down, it cuts the roll material. At the same time, the pressing member 9 presses and fixes the roll material to reduce the possibility of the roll material shifting during cutting and affecting the cutting process.

[0037] It should be noted that the cutting head 7 is an existing device.

[0038] The specific working principle is as follows: the cutting head 7 drives the transmission tooth plate 8 to move down and engage with the one-way transmission rod 3, thereby keeping the one-way transmission rod 3 stationary. When the cutting head 7 moves up, it drives the transmission tooth plate 8 to move up. At this time, the transmission tooth plate 8 drives the one-way transmission rod 3 to rotate, thereby causing the pusher 4 to push the roll material to move equidistantly below the cutting head 7, thus realizing equidistant cutting of the roll material.

[0039] Example 2, refer to Figures 1-3 Based on the same concept as in Embodiment 1 above, this rotary cutting machine further includes:

[0040] A side plate 11 is fixedly installed on the top surface of the base 1. Two inclined grooves 12 are symmetrically opened on the side of the side plate 11 facing the pusher 4. When the pusher plate moves toward the side plate 11, the pusher 4 can be easily controlled to open and close through the inclined grooves 12.

[0041] The pusher 4 includes a horizontal plate 41 and two movable blocks 42. The two movable blocks 42 are symmetrically arranged on the bottom surface of the horizontal plate 41. The two movable blocks 42 are inserted into the slide groove 2 and threaded onto the screw 31. Two horizontal grooves 43 are opened on the front side of the horizontal plate 41. Clamping plates 44 are movably arranged in the two horizontal grooves 43. When the screw 31 rotates, it causes the movable blocks 42 to move along the inner wall of the slide groove 2. Then, the movable blocks 42 drive the horizontal plate 41 to move, and the horizontal plate 41 pushes the roll material to move. The clamping plates 44 are installed through the two horizontal grooves 43, so that the roll material can be clamped and fixed by the clamping plates 44.

[0042] A round rod 45 is fixedly installed at one end of the clamping plate 44 facing the horizontal plate 41. The round rod 45 is connected to the inner wall of the horizontal groove 43 by a first spring 46. The end of the round rod 45 away from the clamping plate 44 extends out of the horizontal plate 41 and slides in cooperation with the inner wall of the inclined groove 12. When the horizontal plate 41 moves toward the side plate 11, the round rod 45 is inserted into the inclined groove 12. As the round rod 45 is continuously inserted into the inclined groove 12, it causes the clamping plate 44 to open and causes the first spring 46 to stretch and deform. When the round rod 45 is separated from the inclined groove 12, the first spring 46 pulls the round rod 45 and the clamping plate 44 to return to their original positions, so that the clamping plate 44 can be used to clamp and fix the roll material.

[0043] The specific working principle is as follows: when the screw 31 rotates, it causes the movable block 42 to move along the inner wall of the slide groove 2, and then the movable block 42 drives the horizontal plate 41 to move, and the horizontal plate 41 pushes the roll material to move, and the clamping plate 44 is installed through the two horizontal grooves 43.

[0044] When the horizontal plate 41 moves toward the side plate 11, the round rod 45 is inserted into the inclined groove 12. As the round rod 45 is continuously inserted into the inclined groove 12, it causes the clamping plate 44 to open and causes the first spring 46 to stretch and deform.

[0045] When the round rod 45 separates from the inclined groove 12, the first spring 46 pulls the round rod 45 and the clamping plate 44 back to their original positions, so that the clamping plate 44 can easily clamp and fix the roll material.

[0046] Example 3, refer to Figure 2 Based on the same concept as in Embodiment 1 above, this rotary cutting machine further includes:

[0047] The pressing component 9 includes a fixed plate 91, a movable plate 92, and a rubber plate 93. The fixed plate 91 is fixedly mounted on the side wall of the cutting head 7. The movable plate 92 is movably inserted into the fixed plate 91. The lower end of the movable plate 92 passes through the fixed plate 91 and is fixedly connected to the rubber plate 93. The rubber plate 93 is connected to the fixed plate 91 by a second spring 94. When the cutting head 7 moves down, it drives the fixed plate 91, the movable plate 92, and the rubber plate 93 to move down synchronously. At this time, the rubber plate 93 abuts against the roll material, thereby pressing and fixing the roll material to reduce the possibility of the roll material shifting position when it is cut.

[0048] The specific working principle is as follows: First, the roll material is placed on the pusher 4, and then the electric push rod 6 is started to push the cutting head 7 to move up and down. As the cutting head 7 moves down, it cuts the roll material. At the same time, the pressing part 9 presses and fixes the roll material to reduce the possibility of the roll material shifting during cutting and affecting the cutting process.

[0049] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
