Description

Technical Field

[0001] This utility model relates to the field of building material processing equipment technology, and more specifically, to a purlin cutting device. Background Technology

[0002] A purlin, also known as a purlin or truss, is a horizontal roof beam, usually perpendicular to the roof truss or rafters. It is mainly used to support the rafters or roofing materials. As a transverse bending member, purlins are usually designed as a single-span simply supported structure. In construction, purlins can be used in two common forms: solid web purlins and light steel truss purlins. Solid web purlins include two types: ordinary steel purlins and light channel steel purlins.

[0003] When cutting purlins, operators often use cutting devices to divide the purlins according to usage requirements. However, while existing cutting devices have basic cutting functions, the cutting length is usually measured manually. This means that before each cutting operation, the operator needs to measure the distance from the cutting point to the end face of the purlin to ensure the stability of the cutting length, which greatly increases the time consumed in the cutting operation. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a purlin cutting device with the advantage of being able to cut to a fixed length.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a purlin cutting device, comprising:

[0006] A machining bed, wherein limit sleeves are fixedly connected to both the upper and lower sides of the right end of the lower surface of the machining bed;

[0007] A length-fixing mechanism is disposed on the lower surface of the machining bed;

[0008] The fixed-length mechanism includes a No. 1 motor, which is fixedly installed on the upper side of the lower surface of the machining bed. The other end of the output shaft of the No. 1 motor is fixedly sleeved with a No. 1 round shaft. A drive rod is fixedly sleeved on the outer surface of the No. 1 round shaft. A movable frame is movably connected to the inner surface of the right side of the drive rod. The right end of the movable frame passes through the limiting sleeve and extends to the right side of the machining bed and is fixedly connected to a baffle plate. The outer surface of the movable frame and the inner surface of the limiting sleeve are movably connected. Rotating the drive rod causes the movable frame and the baffle plate to move left and right.

[0009] As a preferred technical solution of this utility model, the left and right ends of the rear side of the upper surface of the processing bed are fixedly connected to support plates, the upper surface of the support plates is fixedly connected to a top plate, and a pneumatic cylinder is fixedly installed on the right side of the upper surface of the top plate. The bottom end of the pneumatic cylinder penetrates the top plate and extends to the bottom of the top plate and is fixedly connected to an installation sleeve.

[0010] As a preferred embodiment of this utility model, a second motor is fixedly installed on the inner surface of the mounting sleeve, a second round shaft is fixedly sleeved at the other end of the output shaft of the second motor, and a cutting blade located on the left side of the machining bed is fixedly sleeved on the outer surface of the second round shaft.

[0011] As a preferred embodiment of this utility model, a No. 3 motor is fixedly installed on the left side of the upper surface of the top plate, and a No. 3 round shaft is fixedly sleeved on the other end of the output shaft of the No. 3 motor.

[0012] As a preferred embodiment of this utility model, a gear is fixedly sleeved on the outer surface of the No. 3 circular shaft, and a toothed plate is meshed on the outer surface of the gear. There are two toothed plates, and a limiting block is movably connected to the outer surface of each of the two toothed plates. There are two limiting blocks, and the lower surface of each of the two limiting blocks is fixedly connected to the upper surface of the top plate.

[0013] As a preferred embodiment of this utility model, each of the two toothed plates has a movable plate fixedly connected to its outer end. The number of movable plates is two, and the two movable plates are of the same size.

[0014] As a preferred embodiment of this utility model, the bottom ends of the outer surfaces of the two movable plates are fixedly connected to connecting rods, the other end of the connecting rods penetrates the support plate and extends to the inner side of the support plate and is fixedly connected to a clamping plate, and there are two clamping plates, the lower surfaces of the two clamping plates are movably connected to the upper surface of the processing bed.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model, by setting a limiting sleeve, a driving rod, a moving frame, a baffle plate, and a cutting blade, ensures that when the purlin is pressed against the baffle plate, the length of the purlin cut each time is equal to the distance from the cutting blade to the baffle plate. When the first motor starts running, the first round shaft and the driving rod begin to rotate. The rotation of the driving rod drives the moving frame, causing the moving frame and the baffle plate to move left and right under the limitation of the inner surface of the limiting sleeve. During this process, the distance between the cutting blade and the baffle plate changes, thereby changing the length of the purlin cut each time. This achieves fixed-length cutting of the purlin and effectively improves the efficiency of the cutting operation.

[0017] 2. This utility model, by setting up gears, toothed plates, moving plates, connecting rods, and clamping plates, ensures that when the No. 3 motor is running, the No. 3 round shaft and gear will start to rotate. At this time, the two toothed plates will start to move in opposite directions under the meshing of the outer surface of the gear. Finally, when the two clamping plates clamp the outer surface of the purlin, the purlin will be fixed in the current position. This ensures that the purlin will not shake during cutting and ensures the accuracy of the cutting operation. Attached Figure Description

[0026] like Figures 1 to 6 As shown, this utility model provides a purlin cutting device, comprising:

[0027] The machining bed 1 has limit sleeves 2 fixedly connected to both the upper and lower sides of the right end of the lower surface of the machining bed 1.

[0028] A length-fixing mechanism is installed on the lower surface of the machining bed 1;

[0029] The fixed-length mechanism includes a No. 1 motor 3, which is fixedly installed on the upper side of the lower surface of the machining bed 1. The other end of the output shaft of the No. 1 motor 3 is fixedly sleeved with a No. 1 round shaft 4. The outer surface of the No. 1 round shaft 4 is fixedly sleeved with a drive rod 5. The inner surface of the right side of the drive rod 5 is movably connected to a moving frame 6. The right end of the moving frame 6 passes through the limiting sleeve 2 and extends to the right side of the machining bed 1 and is fixedly connected to a baffle plate 7. The outer surface of the moving frame 6 and the inner surface of the limiting sleeve 2 are movably connected. The rotation of the drive rod 5 causes the moving frame 6 and the baffle plate 7 to move left and right.

[0030] When motor 3 is running, shaft 4 and drive rod 5 will start to rotate. The rotation of drive rod 5 will drive the moving frame 6, causing the moving frame 6 and the baffle plate 7 to move left and right under the limit of the inner surface of the limiting sleeve 2, thereby changing the distance between the baffle plate 7 and the processing bed 1.

[0031] Among them, the left and right ends of the rear side of the upper surface of the machining bed 1 are fixedly connected to the support plate 8, the upper surface of the support plate 8 is fixedly connected to the top plate 9, the right side of the upper surface of the top plate 9 is fixedly installed with the pneumatic cylinder 10, the bottom end of the pneumatic cylinder 10 penetrates the top plate 9 and extends to the bottom of the top plate 9 and is fixedly connected to the mounting sleeve 11.

[0032] When the pneumatic cylinder 10 is running, the entire mounting sleeve 11 will begin to move downwards.

[0033] The inner surface of the mounting sleeve 11 is fixedly mounted with a second motor 12, the other end of the output shaft of the second motor 12 is fixedly sleeved with a second round shaft 13, and the outer surface of the second round shaft 13 is fixedly sleeved with a cutting blade 14 located on the left side of the machining bed 1.

[0034] When motor 12 is running, the second circular shaft 13 and the cutting blade 14 will begin to rotate.

[0035] Among them, a No. 3 motor 15 is fixedly installed on the left side of the upper surface of the top plate 9, and a No. 3 round shaft 16 is fixedly sleeved on the other end of the output shaft of the No. 3 motor 15.

[0036] When motor 15 is running, the entire shaft 16 will begin to rotate.

[0037] Among them, a gear 17 is fixedly sleeved on the outer surface of the No. 3 round shaft 16, and a toothed plate 18 is meshed on the outer surface of the gear 17. There are two toothed plates 18, and the outer surfaces of the two toothed plates 18 are movably connected to limit blocks 19. There are two limit blocks 19, and the lower surfaces of the two limit blocks 19 are fixedly connected to the upper surface of the top plate 9.

[0038] The two toothed plates 18 will move in opposite directions under the constraint of the two limiting blocks 19.

[0039] Each of the two toothed plates 18 has a movable plate 20 fixedly connected to its outer end. There are two movable plates 20, and the two movable plates 20 are the same size.

[0040] The two movable plates 20 will move along with the two toothed plates 18 respectively.

[0041] Among them, the bottom of the outer surface of the two movable plates 20 are fixedly connected to the connecting rod 21. The other end of the connecting rod 21 passes through the support plate 8 and extends to the inner side of the support plate 8 and is fixedly connected to the clamping plate 22. There are two clamping plates 22, and the lower surface of the two clamping plates 22 is movably connected to the upper surface of the processing bed 1.

[0042] The two clamps 22 can hold the purlin in place, thus ensuring the stability of the purlin during the cutting process.

[0043] Working principle and usage process of this utility model:

[0044] First, the operator starts motor 3. As motor 3 runs, shaft 4 and drive rod 5 will start to rotate. At this time, the inner surface of drive rod 5 will drive the moving frame 6, so that the moving frame 6 will start to move to the right along the inner surface of limit sleeve 2. When the distance between cutting blade 14 and baffle plate 7 meets the processing requirements, the operator places purlin between the two clamping plates 22 and makes one end of purlin abut against the outer surface of baffle plate 7.

[0045] Then the operator starts motor 15. As motor 15 runs, shaft 16 and gear 17 will start to rotate. Since gear 17 and toothed plate 18 mesh with each other, the two toothed plates 18 will move towards each other under the drive of gear 17 and the limit block 19. Finally, the two clamping plates 22 will clamp the outer surface of the purlin, thus fixing the purlin in the current position.

[0046] At this point, the operator starts the pneumatic cylinder 10 and the second motor 12. The operation of the pneumatic cylinder 10 will cause the mounting sleeve 11 to move towards the purlin, while the operation of the second motor 12 will cause the second round shaft 13 and the cutting blade 14 to rotate. Finally, under the combined action of the mounting sleeve 11 and the cutting blade 14, the cutting blade 14 will complete the cutting operation of the purlin.
