Description

Technical Field

[0001] The utility model relates to the field of cutting machines, in particular to a multi-station cutting machine. Background Art

[0002] Leather cutting refers to the punching and cutting of leather.

[0003] Conventional leather cutting machines, such as patent number 202111519330.8, are named as a shoe material punch cutting machine.

[0004] This cutting machine mainly simplifies the composition structure of the cutting machine table, improves the protection of the cutting head by adding an anti-collision device to avoid damage to the cutting head due to collision, and improves the positioning ability of the shoe material on the conveyor belt by adding a material pressing device to avoid the displacement of the shoe material and poor cutting due to insufficient vacuum adsorption force. By adding a belt pressing device to fix the conveyor belt during processing, it further avoids the displacement of the shoe material and poor cutting due to loose or offset conveyor belt position, and integrates cutting, marking, V-shaped hole punching, and circular hole punching on the same cutting head to complete multi-step punching processing of shoe materials.

[0005] The use of this cutting machine is to cut many pieces of leather with different patterns on a large piece of leather and punch these leathers. It is not difficult to see that the use of a single cutting head in the above leather cutting machine has the problem of low punching efficiency. Utility Model Content

[0006] In order to solve the above problems, the present invention provides a multi-station cutting machine, which solves the above problem of low efficiency by setting more stations.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A multi-station cutting machine includes a cutting machine body with at least two cutting components. The two cutter head assemblies in each cutting component are opposite to each other and driven by an independent moving mechanism. In each cutting component, any one cutter head assembly cuts leather while the other cutter head punches the leather.

[0009] Furthermore, it also includes a console assembly. The cutting machine body is composed of a group of cutting devices spliced together, and the two cutting devices transmit signals to the same group of console assemblies.

[0010] Furthermore, it also includes a barrier belt. The moving mechanism includes a moving track arranged on the side of the cutting device, and a driving component connected to the cutter head assembly. The driving gear provided on the driving component engages with the rack in the moving track. The barrier belt extends to both ends of the moving track in the form of being attached to the outer surface of the driving component and is fixed to both ends of the moving track.

[0011] Furthermore, a plurality of belt guide wheels supporting the barrier belt are provided on the outer surface of the driving assembly, which are used to guide the barrier belt to avoid the driving assembly and maintain the barrier belt outside the driving assembly to cover the connection of the subsequently exposed moving track.

[0012] Furthermore, staggered positions between the belt guide wheels are formed on the driving assembly to guide the barrier belt to avoid the driving assembly, and the barrier belt is staggered around the belt guide wheels at the staggered positions.

[0013] Beneficial effects of the utility model:

[0014] 1. Each set of cutting components has its own punching area. Using more sets of cutting components means that different areas on the leather can be punched simultaneously. Compared with the use of a single cutting head in the prior art, the utility model significantly improves the efficiency of punching.

[0015] 2. The positions of the cutter head assemblies in a single group are opposite to each other. This is to integrate their working areas. After one cutter head assembly completes the cutting of a single pattern, the other cutter head assembly punches the pattern, thereby improving the blanking efficiency of leather.

[0020] like Figure 1 As shown, Figure 1 The utility model is shown as a multi-station cutting machine. The characteristic of this cutting machine is that it adopts a multi-station design, which further shortens the production time of leather by utilizing a larger number of pieces.

[0021] This multi-station cutting machine includes cutting components divided into groups.

[0022] First of all, this is a choice of quantity. Increasing the quantity can improve the efficiency of leather punching.

[0023] In this embodiment, the number is two groups. Of course, according to needs, the number can be three groups, four groups, etc.

[0024] The cutting component contains multiple knife head assemblies which respectively perform different functions. Only the cutting component integrating these functions can completely cut the leather.

[0025] Any set of cutting components includes a first cutter head assembly 1 and a second cutter head assembly 2. The first cutter head assembly 1 and the second cutter head assembly 2 are patented with number CN202221265278.8 and are named CNC multifunctional combined cutter heads.

[0026] This cutter head assembly has two functions: punching and cutting. Based on different usage scenarios, cutting and punching can be selected on the first cutter head assembly 1 and the second cutter head assembly 2.

[0027] With such a design, it is ensured that the cutting and punching processes are carried out continuously. For the usage steps of the existing technology, for example, after a single cutting head punches the leather, the punching mode is deactivated and switched to the cutting mode to cut the leather. In the entire process, the punching process is stopped. The double blade head assemblies in the same group of the utility model perform punching and cutting independently. For example, after the first blade head assembly 1 completes cutting, the first blade head assembly 1 can cut the next pattern on other areas of the leather, and the second blade head assembly 2 can also punch the pattern after the first blade head assembly 1 has cut, which greatly improves the punching efficiency.

[0028] In the embodiment, the cutting machine body is composed of a group of cutting devices 9 spliced together, and the two cutting devices 9 transmit signals with the console assembly 5. It is not difficult to see that while expanding the capacity of leather length, it can also save the use of a console assembly 5 and optimize the space occupancy.

[0029] It should be noted that a moving mechanism is provided on the cutting machine body, and each cutter head assembly is correspondingly mounted on a moving mechanism, and operates back and forth on the leather through the moving mechanism.

[0030] It should be understood that the moving mechanism drives the cutter head assembly to move along the side edge of the cutting machine body.

[0031] like Figure 2-3As shown, the moving mechanism includes a moving track and a driving assembly 6. The moving track is located on the side of the cutting device 9. The driving assembly 6 is provided with a driving gear 61, which is engaged with the rack 62 in the moving track. The cutter head assembly is mounted on the driving assembly 6. When the driving assembly 6 drives the driving gear 61 to rotate, the entire driving assembly 6 moves along the length direction of the rack 62. The cutter head assembly connected to the driving assembly 6 also moves along the driving assembly 6 on the side edge of the cutting machine body.

[0032] The present invention also includes a blocking belt 7, which is provided to cover the moving track to prevent dust and debris generated by cutting from floating into the moving track. The problem of dust and debris accumulating at the meshing position of the driving gear 61 and the rack 62, causing the driving gear 61 to be unable to continue to mesh normally with the rack 62, is completely solved.

[0033] like Figure 2-3 As shown, the blocking belt 7 is arranged in such a manner that its two ends are fixed to the two ends of the moving track; specifically, the blocking belt 7 is extended to the two ends of the moving track in the form of being attached to the outer surface of the driving component 6 and is fixed to the two ends of the moving track. Therefore, when the driving component 6 is moving, there is a relative sliding relationship between the blocking belt 7, so that dust and debris can be prevented from entering the moving track, and interference with the meshing between the driving gear 61 and the rack 62 can be avoided by staggering.

[0034] In other words, the retaining belt 7 is attached to the outer surface of the driving assembly 6 and maintains the retaining belt 7 to cover the connection of the subsequently exposed moving track.

[0035] In an embodiment, a plurality of belt guide wheels 8 may be provided to prop up the barrier belt 7 on the outer surface of the driving assembly 6. The belt guide wheels 8 have a guiding effect and there is rolling friction between them and the barrier belt 7, resulting in relatively little loss to the barrier belt 7.

[0036] like Figure 4 As shown, the blocking belt 7 is guided from the outermost surface of the driving assembly 6 to the two belt guide wheels 8 on the moving track. The blocking belt 7 is staggered around the two belt guide wheels 8. Under the action of the belt guide wheels 8, the blocking belt 7 is located outside the three surfaces of the driving assembly 6. Therefore, the design of the belt guide wheels 8 has the function of lifting the blocking belt 7 from the moving track to engage between the driving gear 61 and the rack 62 when the moving assembly moves forward, and covering the moving track exposed at the rear when the moving assembly moves. The covering is that the belt guide wheels 8 constrain the blocking belt 7 to cover the moving track.

[0037] It can be seen that the two belt guide wheels 8 and the blocking belt 7 that are guided onto the moving track are interlaced and wound around the two belt guide wheels 8. The design point is that the moving track exposed at the rear can be covered in time.

[0038] The driving assembly 6 is of the prior art and has a power component for generating a power source, so its structure will not be further elaborated.

[0039] As mentioned above, this embodiment has at least two sets of cutting components. The usage of the third cutter head assembly 3 and the fourth cutter head assembly 4 in the other set of cutting components can refer to the above description of the first cutter head assembly 1 and the second cutter head assembly 2.

[0040] The above embodiments are merely descriptions of preferred embodiments of the present invention and do not limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary engineering technicians in this field should fall within the scope of protection determined by the claims of the present invention.
