Description

Technical Field

[0001] The utility model belongs to the field of PVC profile processing, and particularly relates to a cutting device for PVC profiles. Background Art

[0002] PVC profile cutting refers to the process of cutting and processing polyvinyl chloride (PVC) profiles. PVC profiles are widely used in construction, home furnishings, and industry. Common profiles include window frames, door frames, guardrails, pipes, and decorative strips. Cutting is a crucial step in adjusting the size or customizing the shape of these profiles.

[0003] When traditionally cutting PVC profiles, cutting lines are often drawn on the surface of the PVC profile manually, and then the cutting machine is manually controlled to adjust the position of the cutting tool, and the PVC profile is manually advanced to contact the cutting tool to achieve the cutting operation of the profile. However, this operation method is affected by factors such as the operator's advancement speed and stability. When batch cutting is performed, the advancement distance of the PVC profile is not accurate enough, which can easily lead to inaccurate cutting and affect the overall structural stability and consistency of the PVC profile. At the same time, manually advancing the wooden board requires the operator to expend considerable physical strength and energy, especially in the case of large-scale cutting. Considering the cutting accuracy and efficiency of PVC profiles, a cutting device for PVC profiles is proposed to solve this problem. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides a cutting device for PVC profiles, comprising a platform frame;

[0006] The platform frame is constructed in the form of a rectangular frame and a cutting platform is installed thereon;

[0007] The upper surface of the cutting platform is equipped with two groups of profile propulsion assemblies, and a propulsion beam is installed between the two groups of profile propulsion assemblies;

[0008] The two groups of profile pushing assemblies each include two positioning plates arranged on the upper end surface of the cutting platform, the two positioning plates are equipped with bearings, and a threaded screw is rotatably arranged between the two bearings;

[0009] The outside of the threaded screw is meshed with a screw nut; the outsides of the two screw nuts are both sleeved with a slider seat.

[0010] As a further improvement of the present invention, the propulsion beam is installed between the two slider seats, and the bottom of the propulsion beam is in contact with the cutting platform.

[0011] As a further improvement of the present invention, the two slider seats are provided with slots on their opposite sides, and a plurality of compression springs are installed in the slots of the two slider seats and are connected to a clamping plate through the compression springs.

[0012] As a further improvement of the present invention, a reciprocating motor is further installed on one side of the positioning plates in the two groups of profile propulsion assemblies, and the output end of the reciprocating motor passes through the positioning plate and extends to be connected to one end of the threaded screw.

[0013] As a further improvement of the present invention, a gantry is provided on the upper end face of the cutting platform, and a first linear screw module is provided on the upper part of the gantry along its horizontal direction, a second linear screw module is assembled on the first linear screw module, and the second linear screw module is arranged perpendicular to the first linear screw module; a cutting tool body is assembled on the second linear screw module.

[0014] In general, the above technical solutions conceived by the present invention have the following beneficial effects compared with the prior art:

[0015] In actual use, the PVC profile cutting device of the present invention cooperates with the mutual movement of multiple structures arranged in the profile pushing assembly, so that the pushing beam installed between the two groups of profile pushing assemblies can be driven by the profile pushing assembly to move linearly above the cutting platform; when the pushing beam is moving, the PVC profile placed on the cutting platform can be pushed by the pushing beam, so that it can move stably linearly above the cutting platform; compared with the traditional manual pushing of PVC profiles, the profile pushing assembly and pushing beam of the present application can accurately control the linear movement of the PVC profile, thereby ensuring the accurate position of the cutting tool body when cutting the PVC profile.

[0016] The PVC profile cutting device of the utility model can make the PVC profile more uniform and stable during cutting and transportation by precisely advancing the PVC profile with the advancing crossbeam and elastically clamping the PVC profile with the two clamping plates, thereby helping to improve the cutting quality and efficiency, thereby ensuring the accuracy and consistency of the cutting operation.

[0017] The cutting device for PVC profiles of the present invention controls the motion between the first linear screw module and the second linear screw module, so that the cutting tool body installed on the second linear screw module can be freely adjusted in position above the cutting platform. Therefore, when the PVC profile moves to the bottom of the cutting tool body, the first linear screw module and the second linear screw module can ensure that the cutting tool body can achieve precise position adjustment above the cutting platform, thereby reducing cutting errors and meeting the cutting requirements of profiles of different shapes. Moreover, through the control of the first linear screw module and the second linear screw module, as well as the stable linear propulsion of the propulsion beam, the cutting tool body has strong repeatability when cutting the PVC profile, ensuring the consistency of the cutting.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example

[0024] Depend on Figure 1-3 Provided is a cutting device for PVC profiles, comprising a platform frame 1;

[0025] The platform frame 1 is constructed in a rectangular frame and a cutting platform 2 is assembled thereon;

[0026] Two groups of profile pushing components 3 are assembled on the upper end surface of the cutting platform 2, and a pushing beam 4 is assembled between the two groups of profile pushing components 3;

[0027] The two sets of profile pushing assemblies 3 each include two positioning plates 31 disposed on the upper end surface of the cutting platform 2. A bearing 32 is assembled in each of the two positioning plates 31. A threaded screw 33 is rotatably disposed between the two bearings 32.

[0028] A screw nut 34 is meshed with the outside of the threaded screw 33 ; and a slider seat 35 is sleeved on the outside of the two screw nuts 34 .

[0029] In this embodiment, in actual use, through the mutual movement coordination of multiple structures arranged in the profile pushing assembly 3, the pushing beam 4 installed between the two groups of profile pushing assemblies 3 can be driven by the profile pushing assembly 3 to move linearly above the cutting platform 2; when the pushing beam 4 is moving, the PVC profile placed on the cutting platform 2 can be pushed by the pushing beam 4, thereby moving stably linearly above the cutting platform 2; compared with the traditional manual pushing of the PVC profile, the profile pushing assembly 3 and the pushing beam 4 of the present application can accurately control the linear movement of the PVC profile, thereby ensuring the accurate position of the cutting tool body 8 when cutting the PVC profile.

[0030] Furthermore, by precisely advancing the PVC profile by the propulsion beam 4 and elastically clamping the PVC profile by the two clamping plates 38, the PVC profile can be cut and transported more evenly and stably, which helps to improve the cutting quality and efficiency, thereby ensuring the accuracy and consistency of the cutting operation.

[0031] Specifically, refer to Figure 1-3 The pushing beam 4 is installed between the two slider seats 35, and the bottom of the pushing beam 4 is in contact with the cutting platform 2.

[0032] In this embodiment, the propulsion beam 4 is provided to stably propel the PVC profile.

[0033] Specifically, refer to Figure 3 The two slider seats 35 have slots on their opposite sides. A plurality of compression springs 37 are installed in the slots of the two slider seats 35 and are connected to a clamping plate 38 through the compression springs 37 .

[0034] In this embodiment, during use, the user places the PVC profile to be cut on the cutting platform 2, and places the PVC profile between the two clamping plates 38, and at the same time makes one side of the PVC profile fit with one side of the propulsion beam 4; when the PVC profile is between the two clamping plates 38, the reciprocating motor 36 elastically presses the clamping plates 38, so that the two clamping plates 38 can elastically squeeze the two sides of the PVC profile, thereby ensuring the stable placement of the PVC profile.

[0035] Furthermore, the user can adapt the clamping plate 38 to PVC profiles of different sizes by changing the length of the clamping plate 38 so as to clamp them.

[0036] Specifically, refer to Figure 2 A reciprocating motor 36 is also installed on one side of one of the positioning plates 31 in the two groups of profile pushing assemblies 3. The output end of the reciprocating motor 36 passes through the positioning plate 31 and extends to be connected to one end of the threaded screw 33.

[0037] In this embodiment, during use, the reciprocating motor 36 can be used to control the rotation of the threaded screw 33 .

[0038] Furthermore, the power connection method of the reciprocating motor 36 is the existing technology, and the control circuit can be implemented by simple programming by technicians in this field. It is common knowledge in this field and is only used without modification. Therefore, the control method and circuit connection will not be described in detail.

[0039] Specifically, refer to Figure 1-2 A gantry 5 is mounted on the upper end face of the cutting platform 2, and a first linear screw module 6 is mounted on the upper part of the gantry 5 along its horizontal direction. A second linear screw module 7 is assembled on the first linear screw module 6, and the second linear screw module 7 is arranged perpendicular to the first linear screw module 6; a cutting tool body 8 is assembled on the second linear screw module 7.

[0040] In this embodiment, through the motion control between the first linear screw module 6 and the second linear screw module 7, the cutting tool body 8 installed on the second linear screw module 7 can be freely adjusted in position above the cutting platform 2, so that when the PVC profile moves to the bottom of the cutting tool body 8, the first linear screw module 6 and the second linear screw module 7 can ensure that the cutting tool body 8 can be accurately adjusted in position above the cutting platform 2, thereby reducing cutting errors and meeting the cutting requirements of profiles of different shapes. Moreover, through the control of the first linear screw module 6 and the second linear screw module 7, as well as the stable linear propulsion of the propulsion beam 4, the cutting tool body 8 has strong repeatability when cutting the PVC profile, ensuring the consistency of the cutting.

[0041] The utility model of the PVC profile cutting device:

[0042] Step 1: In actual use, when the user needs to cut a PVC profile, first place the PVC profile to be cut on the cutting platform 2 and place the PVC profile between the two clamping plates 38. At the same time, one side of the PVC profile is aligned with one side of the propulsion beam 4. When the PVC profile is between the two clamping plates 38, the reciprocating motor 36 elastically presses the clamping plates 38, so that the two clamping plates 38 can elastically squeeze the two sides of the PVC profile, thereby ensuring the stable placement of the PVC profile.

[0043] Step 2: The user connects the two reciprocating motors 36 in the two profile pushing assemblies 3 to a power source. The reciprocating motors 36 will then drive the threaded screws 33 to rotate. As the two threaded screws 33 rotate, they are limited by the connection of the pushing beam 4, so that the screw nuts 34 engaged with the outside of the threaded screws 33 drive the slider seat 35 to move linearly along the travel range of the screw nuts 34. When the slider seat 35 moves, it drives the pushing beam 4 to move linearly. At this time, the PVC profile is clamped by the clamping plate 38 and pushed by the pushing beam 4, so that the PVC profile can be linearly pushed above the cutting platform 2.

[0044] Step 3: When the PVC profile is driven by the propulsion beam 4 and is thus propelled in a straight line, the user controls the second linear screw module 7 so that the cutting tool body 8 assembled on the second linear screw module 7 can be adjusted in height. The user controls the height of the cutting tool body 8 until it contacts the PVC profile. At this time, the cutting operation of the PVC profile can be achieved under the rotation cutting of the cutting tool body 8. At the same time, the user can also adjust the first linear screw module 6 so that the second linear screw module 7 can drive the cutting tool body 8 to perform horizontal linear adjustment along the top of the cutting platform 2. At this time, through the horizontal linear adjustment of the cutting tool body 8, cutting operations can also be performed on different positions of the PVC profile.

[0045] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
