Description

Technical Field

[0001] The invention relates to the technical field of hot pressing forming machines, in particular to hot pressing forming equipment with adjustable levelness. Background Art

[0002] Thermoforming machine is a kind of equipment that uses high temperature and high pressure to process materials into shapes. It puts plastic or rubber raw materials into a mold, clamps it between the upper and lower electric heating plates, and applies pressure under the intelligent constant temperature of the electric heating plates to shape the raw materials. It is a kind of equipment widely used in the field of material processing.

[0003] The utility model patent with authorization announcement number CN202322526990.X discloses a hot pressing forming machine for PVC wall panels, which includes a base, support columns are fixedly installed on both sides of the top of the base, a top plate is fixedly installed on the top of the support column, a cylinder is fixedly installed on the top of the top plate, an upper pressing plate is fixedly installed on the telescopic end of the cylinder, and a lower pressing plate is fixedly installed on the top of the base, a cross bar is fixedly installed between the two support columns, grooves are provided on opposite sides of the two cross bars, one of the cross bars is located in the groove and a threaded rod is rotatably installed, and the other cross bar is located in the groove and a guide rod is fixedly installed, a connecting box is provided between the two cross bars, one end of the connecting box is threadedly connected to the threaded rod, and the other end of the connecting box is slidably connected to the guide rod, and a cleaning brush is fixedly installed on the top and bottom ends of the connecting box.

[0004] Although the hot press forming machine used for PVC wall panels facilitates cleaning of the pressing plate by means of a cleaning brush, the device still has the following problems in actual use: in the device, the cleaning brush is directly fixed on the connecting box. When the pressing plate needs to be cleaned, the horizontal movement of the connecting box will drive the bristles to move horizontally synchronously, and then the initial cleaning of the pressing plate is achieved through the friction between the bristles and the surface of the pressing plate. However, in actual applications, since the pressing plate is heated during operation, some material debris forms a tight adhesion state with the surface of the pressing plate. Therefore, it is often difficult to effectively remove these stubbornly attached debris by simply relying on the simple horizontal movement of the bristles. In view of this, we propose a hot press forming device with adjustable horizontality. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a hot pressing forming device with adjustable level.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is as follows: A thermoforming device with adjustable levelness comprises a cabinet, two machine bases are arranged above the cabinet, support rods are fixed at four corners between the two machine bases, an electric cylinder is installed on the top of the upper machine base, a pressing plate is installed at the end of the piston rod of the electric cylinder, and a support is fixed on the top of the lower machine base; A cleaning mechanism is provided between the pressure plate and the support, and the cleaning mechanism includes a shell that can move horizontally, and connecting blocks are fixed at both ends of the bottom of the shell; a rotating shaft is rotatably installed inside the shell, and a plurality of main bevel gears are coaxially keyed to the outer wall of the rotating shaft, and connecting shafts are rotatably installed on the upper and lower sides of the main bevel gears, and the end of the connecting shaft passes through the outer wall of the shell, and a secondary bevel gear is coaxially keyed to one end of the connecting shaft, and the secondary bevel gear is meshed with the corresponding main bevel gear, and a turntable is coaxially keyed to the other end of the connecting shaft, and bristles for cleaning the pressure plate and the support are fixed to the outer wall of the turntable; a second motor for driving the rotating shaft to rotate is installed on the outer wall of the shell.

[0008] Furthermore, a guide rod is fixedly connected in the strip-shaped groove at the rear side by bolts, and the guide rod passes through the connecting block at the rear side and is slidably connected to the connecting block.

[0009] Furthermore, the cabinet is provided with supporting feet at four corners of the bottom, the bottom of the supporting feet is provided with threaded grooves, and the threaded grooves are threadedly connected with horizontal adjustment bolts.

[0010] Furthermore, a level is installed at each of the four corners of the top of the cabinet, and the level is fixedly connected to the cabinet by bolts.

[0011] Furthermore, a collecting component is installed on the outer wall of the shell, and the collecting component includes a box body which is fixedly connected to the outer wall of the shell and has a hollow structure. The upper and lower walls of the box body are provided with multiple collecting grooves.

A filter is fixed at the opening of the connecting frame.

[0012] Furthermore, the cross-sectional shape of the connecting frame is U-shaped, and the size of the connecting frame is matched with the inner cavity size of the connecting sleeve.

[0013] Furthermore, the cross-sectional shape of the collecting groove is rectangular, and the plurality of collecting grooves are linearly and evenly spaced in the horizontal direction.

[0014] Furthermore, the box body is fixedly connected to the shell body by bolts, and the connecting sleeve is fixedly connected to the box body by bolts.

[0015] Furthermore, a threaded hole is provided at the bottom end of the turntable, and a threaded groove threadably connected to the threaded hole is provided at the end of the connecting shaft.

[0020] Example 1 See also Figure 1-Figure 5As shown, a hot pressing forming device with adjustable horizontality includes a cabinet 1, two machine bases 2 are arranged above the cabinet 1, support rods 20 are fixed at the four corners between the two machine bases 2, an electric cylinder 21 is installed on the top of the upper machine base 2, a pressing plate 22 is installed at the end of the piston rod of the electric cylinder 21, and a support 23 is fixed on the top of the lower machine base 2; a cleaning mechanism 3 is arranged between the pressing plate 22 and the support 23, and the cleaning mechanism 3 includes a shell 35 that can move horizontally, and connecting blocks 34 are fixed at both ends of the bottom of the shell 35; a rotating shaft 36 is rotatably installed inside the shell 35, and the rotating shaft 36 is rotatably installed inside the shell 35. The outer wall of 6 is coaxially keyed to connect multiple main bevel gears 360, and connecting shafts 37 are rotatably installed on the upper and lower sides of the main bevel gears 360. The end of the connecting shaft 37 passes through the outer wall of the shell 35, and one end of the connecting shaft 37 is coaxially keyed to connect a secondary bevel gear 370, and the secondary bevel gear 370 is meshed with the corresponding main bevel gear 360. The other end of the connecting shaft 37 is coaxially keyed to connect a turntable 38, and the outer wall of the turntable 38 is fixed with bristles 380 for cleaning the pressure plate 22 and the support 23; the outer wall of the shell 35 is installed with a second motor 39 for driving the rotating shaft 36 to rotate. The cleaning mechanism 3 includes two symmetrical fixed seats 30, and the support rod 20 passes through the fixed seats 30 and is fixedly connected to the fixed seats 30; two end faces of the two fixed seats 30 that are away from each other are each provided with a strip groove 300, a threaded rod 31 is rotatably installed in the front strip groove 300, a first motor 32 for driving the threaded rod 31 to rotate is installed at the right end of the fixed seat 30, and a connecting block 34 on the front side is threadedly connected to the threaded rod 31.

[0021] In this embodiment, a guide rod 33 is fixedly connected to the strip groove 300 at the rear side by bolts, and the guide rod 33 passes through the connection block 34 at the rear side and is slidably connected to the connection block 34. The provision of the guide rod 33 enhances the stability and smoothness of the structure. This design helps to ensure that the housing 35 can maintain precise alignment when moving or adjusting, while reducing friction and wear, and extending the service life of the device.

[0022] In this embodiment, the four corners of the bottom of the cabinet 1 are all fixed with supporting feet 12, the bottom of the supporting feet 12 is provided with threaded grooves 120, and the threaded grooves 120 are all threaded with horizontal adjustment bolts 13. This design enables the cabinet 1 to be fine-tuned according to the unevenness of the actual installation ground to ensure that the cabinet 1 is placed horizontally; it not only improves the stability of the cabinet 1, but also helps to protect the electronic equipment in the cabinet 1 from vibration and tilt, and ensures the normal operation of the hot pressing molding equipment.

[0023] In this embodiment, a level 14 is installed at each of the four corners of the top of the cabinet 1, and the level 14 is fixedly connected to the cabinet 1 by bolts. This design allows the operator to visually observe the horizontal state of the cabinet 1.

[0024] In this embodiment, two cabinet doors 10 are hinged at the front opening of the cabinet 1, and handles 11 are installed on the outer walls of the cabinet doors 10. The arrangement of the cabinet doors 10 protects the electronic equipment in the cabinet 1, and the handles 11 facilitate opening and closing of the cabinet doors 10.

[0025] During specific use, the user first turns on the power of the first motor 32 and the second motor 39, and the first motor 32 and the second motor 39 start working. The output shaft of the first motor 32 rotates to drive the threaded rod 31 to rotate. Since the threaded rod 31 is threadedly connected to the connecting block 34, the shell 35 moves horizontally. At the same time, the output shaft of the second motor 39 rotates to drive the rotating shaft 36 and the main bevel gear 360 to rotate. Since the main bevel gear 360 is meshed with the secondary bevel gear 370, the secondary bevel gear 370 rotates and drives the connecting shaft 37 and the turntable 38 to rotate synchronously. The turntable 38 also drives the bristles 380 to rotate. As the shell 35 moves horizontally, when the rotating bristles 380 contact the bottom of the pressing plate 22 and the top of the support 23, the bottom of the pressing plate 22 and the top of the support 23 can be cleaned.

[0026] Example 2 See also Figure 6-Figure 7 As shown, this embodiment provides the following technical solutions on the basis of embodiment 1: a collecting component 4 is installed on the outer wall of the shell 35, and the collecting component 4 includes a box body 40 which is fixedly connected to the outer wall of the shell 35 and has a hollow structure, and the upper and lower walls of the box body 40 are provided with multiple collecting grooves 400, and a connecting sleeve 41 is fixed to the outer wall of the box body 40, and an exhaust fan 42 is installed at the end of the connecting sleeve 41, and the exhaust fan 42, the connecting sleeve 41 and the box body 40 are connected in sequence, and a notch 410 is opened at the top of the box body 40, and a plug plate 43 is inserted in the notch 410, and a connecting frame 44 is fixed to the bottom end of the plug plate 43, and the connecting frame 44 is inserted into the interior of the connecting sleeve 41, and a filter screen 45 is fixed at the opening of the connecting frame 44.

[0027] In this embodiment, the cross-section of the connecting frame 44 is U-shaped, and the size of the connecting frame 44 is adapted to the inner cavity size of the connecting sleeve 41. This design enhances the stability and firmness between the connecting frame 44 and the connecting sleeve 41. The U-shaped cross-section provides a larger contact area, which helps to disperse stress and prevent deformation or damage caused by uneven force. At the same time, this design is also easy to install and disassemble, and improves the convenience of maintenance.

[0028] In this embodiment, the cross-section of the collecting groove 400 is rectangular, and the plurality of collecting grooves 400 are linearly and evenly spaced in the horizontal direction. This design enables the collecting groove 400 to collect debris and dust more effectively.

[0029] In this embodiment, the box body 40 is fixedly connected to the housing 35 by bolts, and the connecting sleeve 41 is fixedly connected to the box body 40 by bolts. The bolted connection mode has the advantages of simple structure, reliable connection, easy disassembly and maintenance. The bolt connection can provide sufficient strength and rigidity to ensure close fit and stable operation between the components. At the same time, the bolt connection is also convenient for adjustment and replacement as needed, which improves the flexibility and maintainability of the equipment.

[0030] When cleaning the bottom of the pressure plate 22 and the top of the support 23, the user first turns on the power of the exhaust fan 42. The debris and dust generated during cleaning enter the box body 40 through the multiple collection grooves 400 on the upper and lower sides, and enter the connecting sleeve 41 through the box body 40. When the debris and dust move to the filter net 45, the debris and dust are intercepted, and finally the filtered air is discharged through the exhaust fan 42.

[0031] Example 3 See also Figure 8 As shown, the difference between this embodiment and embodiment 1 is that a threaded hole 381 is provided at the bottom end of the rotating disk 38 , and a threaded groove threadably connected to the threaded hole 381 is provided at the end of the connecting shaft 37 .

[0032] It is understandable that the threaded connection makes it easy to disassemble the turntable 38, thereby facilitating the replacement or cleaning of the turntable 38 and the bristles 380 at a later time.

[0033] It should be added that the tightening direction of the turntable 38 in this embodiment is opposite to the rotation direction of the connecting shaft 37. When the connecting shaft 37 continues to rotate, the reverse design will make the turntable 38 more tightly fixed on the shaft, avoiding the turntable 38 from being separated due to rotational force or vibration. This design can effectively prevent the turntable 38 from loosening or separating, ensuring the safety and stability of the turntable 38.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention.
