Description

Technical Field

[0001] This utility model relates to the field of bag making machine technology, specifically a quick-switching mechanism for bag making machine cutters. Background Technology

[0002] Currently, as an automated fabric cutting device, the cutting machine will cut the material that continuously passes through the cutting blade into a preset size according to the cutting dimensions, so as to facilitate subsequent processing. When cutting materials, some materials have special requirements for the cutting edge shape. Therefore, it is necessary to change the cutting blade to the corresponding shape according to the cutting shape requirements to change the edge style of the material. However, the repeated changing of the cutting blade takes a certain amount of time, which reduces work efficiency. Therefore, a cutting blade switching mechanism for cutting machines is proposed to solve the above-mentioned problems. Utility Model Content

[0003] To achieve the above objectives, this utility model provides the following technical solution: a quick-switching mechanism for a bag-making machine cutter, comprising symmetrically arranged guide rods 1 and guide sleeves 3, a connecting block 2 connected to a driving component on the guide sleeve 3, and a cutter holder 8 between the guide sleeves 3, characterized in that: the middle part of the cutter holder 8 is a cuboid, with rotating shafts 13 at both ends of the cuboid, and cutter locking plates 6 and cutter fixing plates 14 at both the upper and lower ends of the cuboid, with cutter 1 5 and cutter 2 7 respectively located at the upper and lower ends of the cutter holder 8; the guide sleeve 3 is provided with mounting blocks 17, and both the guide sleeve 3 and the mounting blocks 17 are provided with supporting half-holes 18 that match the rotating shafts 13; a fixing sleeve 4 is provided above the guide sleeve 3 to fix and make the cutter vertical.

[0004] Furthermore, the fixing sleeve 4 is provided with a vertical guide groove 11 that cooperates with the tool holder 8, and the vertical guide groove 11 is provided with a fixing hole 12 that cooperates with the fixing hole 15 on the fixing tool holder 8.

[0005] Furthermore, the fixed sleeve 4 is also provided with a fixed hole 9 that connects to the guide sleeve 3, and the guide sleeve 3 is provided with a thread 16 that mates with the fixed hole 9.

[0006] Furthermore, the cutter fixing plate 14 is on the same plane and perpendicular to the cutter holder 8; the cutter locking plate 6 is detachable and locked to the cutter fixing plate 14 by bolts.

[0007] This utility model has the following advantages: First, when the cutter needs to be replaced, it is only necessary to rotate the cutter holder to switch the corresponding cutter to the cutting position, which facilitates and quickly replaces the cutter and effectively improves work efficiency; Second, after the cutter position is changed, the angle of the cutter holder can be fixed by the fixing sleeve to prevent the cutter holder from rotating on its own during use, which would cause the cutter to shift; At the same time, the bolts facilitate the installation and removal of the cutter on the cutter holder.

Detailed Implementation

[0010] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0011] Please see Figure 1-4 This utility model provides a technical solution: including symmetrically arranged guide rods 1 and guide sleeves 3, with a connecting block 2 on the guide sleeve 3 connected to the driving component, and a tool holder 8 between the guide sleeves 3.

[0012] The middle part of the tool holder 8 is a cuboid, and the two ends of the cuboid are provided with rotating shafts 13. The guide sleeve 3 and the mounting block 17 are both provided with supporting half holes 18 that match the rotating shafts 13. After the tool holder 8 is installed, the mounting block 17 is locked, which ensures that the tool holder 8 can rotate between the guide sleeves 3.

[0013] Both the upper and lower ends of the blade holder 8 are provided with a blade locking plate 6 and a blade fixing plate 14. The first blade 5 and the second blade 7 are respectively located between the blade locking plate 6 and the blade fixing plate 14 at the upper and lower ends of the blade holder 8. The blade fixing plate 14 is on the same plane and perpendicular to the blade holder 8. The blade locking plate 6 is detachable and locked to the blade fixing plate 14 with bolts. When it is necessary to change the type of blade, the blade locking plate 6 is removed and the blade is replaced. After the replacement is completed, the blade locking plate 6 is locked again.

[0014] Above the guide sleeve 3 is a fixing sleeve 4 that fixes and makes the cutter vertical. The fixing sleeve 4 has a relief groove 10 to avoid the guide rod 1 and a vertical guide groove 11 that cooperates with the cutter holder 8. The vertical guide groove 11 has a fixing hole 12 that cooperates with the fixing hole 15 on the fixed cutter holder 8. At the same time, the fixing sleeve 4 also has a fixing hole 9 that connects to the guide sleeve 3. The guide sleeve 3 has a thread 16 that cooperates with the fixing hole 9.

[0015] The specific working principle is as follows: When it is necessary to switch the cutter, remove the fixing sleeve 4, rotate the cutter holder 8 to switch the upper and lower cutter 1 5 and cutter 2 7. Then reinstall the fixing sleeve 4. One side of the fixing sleeve 4 is fixed to the guide sleeve 3, and the other side restricts the cutter holder 8 to make it vertical. The fixing hole 2 12 and fixing hole 3 15 are passed through the bolt and locked. This way, the cutter can be quickly switched.
