Description

Technical Field

[0001] The utility model relates to the technical field of raw tape production, in particular to a stretching machine with a cutter. Background Art

[0002] As we all know, stretching machines are used to stretch items. In the production of raw tape, in order to make the raw tape thinner and improve the sealing performance of the raw tape for water pipe connections, a stretching machine is used to stretch the raw tape. However, the process of stretching the raw tape will inevitably change the width of the raw tape, making the wound raw tape very wide. Therefore, the raw tape must be slit before it can be used, which requires an additional slitting process to form the raw tape. Utility Model Content

[0003] The purpose of the utility model is to solve the problem in the prior art that the width of the raw tape will inevitably change during the stretching process, making the rolled raw tape very wide, so that the raw tape can only be used after it is cut, and a stretching machine with a cutter is proposed.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A stretching machine with a cutter is designed, comprising two support plates, with a gap between the two support plates, a number of rotating shafts installed between the two support plates through bearings, stretching rollers provided on the several rotating shafts, transmission mechanisms provided on the several rotating shafts, a fixed seat provided on one side of the two support plates, a number of tool assemblies provided on the fixed seat, and a moving mechanism provided between the fixed seat and the two support plates.

[0006] Preferably, the moving mechanism includes grooves opened on the two support plates, and the two ends of the fixed seat are respectively slidably set on the two grooves. There is a transition fit between the fixed seat and the two grooves, and a threaded rod is installed in one of the grooves through a bearing, and the thread of the threaded rod passes through the fixed seat.

[0007] Preferably, the two grooves are arranged in a T-shape.

[0008] Preferably, a wear-resistant coating is provided on one side of the fixing seat that contacts the two grooves.

[0009] Preferably, a sleeve tube is installed in the other groove, the sleeve tube slides through the fixing seat, a sealing block is threadedly connected to the sleeve tube, and hydraulic oil is added into the sleeve tube.

[0010] Preferably, two observation windows are provided on one of the support plates, and there is a gap between the two observation windows.

[0011] Preferably, the two observation windows on the support plate are not connected to the groove.

[0012] The utility model proposes a stretching machine with a cutter, which has the beneficial effect that the stretching machine with a cutter can cut the raw tape into multiple raw tapes with smaller widths before working through an external winding device, thereby improving the processing efficiency of the raw tape. In the utility model, the tool assembly is fixed on the fixed seat, so it is convenient to adjust the distance between the tool assembly and the raw tape, and then it can be adjusted whether the raw tape is cut.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] Example 1

[0020] Reference Figure 1-4A stretching machine with a cutter comprises two support plates 1, with a gap between the two support plates 1, a number of rotating shafts 2 are installed between the two support plates 1 through bearings, a number of rotating shafts 2 are provided with stretching rollers 3, a transmission mechanism is provided on the number of rotating shafts 2, a fixed seat 4 is provided on one side of the two support plates 1, a number of tool assemblies 5 are provided on the fixed seat 4, a moving mechanism is provided between the fixed seat 4 and the two support plates 1, the moving mechanism includes grooves 6 opened on the two support plates 1, the two ends of the fixed seat 4 are respectively slidably set on the two grooves 6, the fixed seat 4 and the two grooves 6 are transition fit, a threaded rod 9 is installed in one of the grooves 6 through a bearing, and the threaded rod 9 threadedly penetrates the fixed seat 4.

[0021] A heating mechanism is provided on the inner wall of one of the support plates 1, so that the stretched raw tape can be heated, thereby preventing the raw tape from breaking during the stretching process. The transmission mechanism is a transmission wheel 11 and a transmission chain 12, combined with the attached Figure 1-2 It can be seen that there are several transmission wheels 11 and transmission chains 12, and when one of the rotating shafts 2 rotates, several transmission wheels 11 and several transmission chains 12 will rotate with other rotating shafts 2, so that several stretching rollers 3 will rotate, thereby improving the stretching effect of the device on the raw tape.

[0022] Combined with attachment Figure 3-4 After the raw tape is inserted between several stretching rollers 3 in sequence and the raw tape is in a stretched state, the threaded rod 9 is rotated by using a torque wrench, so that the threaded rod 9 and the fixed seat 4 move between the two support plates 1, so that the tool assembly 5 on the fixed seat 4 cuts the raw tape, so that the raw tape can be cut into multiple raw tapes of smaller width before the external winding device works, thereby improving the processing efficiency of the raw tape. In the utility model, the tool assembly 5 is fixed on the fixed seat 4, so it is convenient to adjust the distance between the tool assembly 5 and the raw tape, and then it can be adjusted whether the raw tape is cut.

[0023] Example 2

[0024] Based on the optimization of Example 1, refer to Figure 1-4 A sleeve tube 7 is installed in another groove 6, and the sleeve tube 7 slides through the fixed seat 4. A sealing block 8 is threadedly connected to the sleeve tube 7, and hydraulic oil is added to the sleeve tube 7.

[0025] By arranging the cooperation between the sleeve tube 7 and the sealing block 8, the sealing block 8 squeezes the hydraulic oil during the movement in the sleeve tube 7, so that the outer side of the sleeve tube 7 squeezes the fixed seat 4, so that after the fixed seat 4 is fixed in the position in the groove 6, the fixed seat 4 will not move, and when the sleeve tube 7 does not fix the fixed seat 4, the friction force of the fixed seat 4 moving in the two grooves 6 can be reduced, making the position adjustment of the fixed seat 4 smoother.

[0026] Example 3

[0027] Based on the optimization of Example 1-2, refer to Figure 1-4 The two grooves 6 are set to a T-shape, and the side of the fixing seat 4 that contacts the two grooves 6 is provided with a wear-resistant coating.

[0028] The wear-resistant coating is formed by nitriding treatment, which can improve the mechanical properties of the device and thus extend the service life of the device; by setting both grooves 6 to a T-shape, the connection effect between the two support plates 1 and the fixing seat 4 is made better.

[0029] Example 4

[0030] Based on the optimization of Examples 1-3, refer to Figure 1-4 Two observation windows 10 are provided on one of the support plates 1 , and there is a gap between the two observation windows 10 . The two observation windows 10 on the support plate 1 are not connected to the groove 6 .

[0031] By setting up the observation window 10, the contact situation between the tool assembly 5 and the raw tape can be seen more intuitively, so that it is convenient to know whether the tool assembly 5 needs to be cleaned; the two observation windows 10 are set to be not connected to the groove 6, so as to avoid the structure of the groove 6 from being damaged, thereby improving the connection stability between the groove 6 and the fixing seat 4.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
