Description

Technical Field

[0001] This utility model relates to the field of preform production, specifically to a release agent spraying device and a preform production line. Background Technology

[0002] During the production of precast components, a release agent needs to be sprayed into the mold to facilitate demolding. Existing release agent spraying devices require the mold to be stopped at a predetermined position and the spraying unit to move along the length of the mold to complete the release agent application. Furthermore, specific designs are needed for spraying the mold's sidewalls to ensure the quality of the release agent application. These factors contribute to the complexity and high manufacturing and operating costs of existing release agent spraying devices. Therefore, the applicant has developed a novel release agent spraying device. Utility Model Content

[0003] The purpose of this application is to provide a novel mold release agent spraying device with a simple structure and low manufacturing cost. This is achieved through the following solution:

[0004] In the first aspect, the mold release agent spraying device provided in this application includes a support frame, a mounting base, a drive unit and a mold release agent spraying unit, wherein the mounting base is connected to the support frame and the drive unit is mounted on the mounting base;

[0005] The release agent spraying unit is mounted on the mounting base. The release agent spraying unit includes a drive shaft, a drive rod, and a nozzle. The drive shaft is vertically arranged, and the drive unit is connected to the upper end of the drive shaft. The middle part of the drive shaft is rotatably connected to the upper part of the mounting base. The upper end of the drive rod is ball-jointed to the eccentric part of the lower end of the drive shaft. The middle part of the drive rod is ball-jointed to the lower part of the mounting base. The nozzle is mounted on the lower end of the drive rod.

[0006] By including a drive shaft, a drive rod, and a nozzle in the mold release agent spraying unit, and further connecting the drive shaft to the drive unit, the middle of the drive shaft is rotatably connected to the mounting base. The upper end of the drive rod is ball-jointed to the eccentric part of the lower end of the drive shaft, and the middle of the drive rod is ball-jointed to the lower part of the mounting base. During operation, the nozzle located at the lower end of the drive rod can perform circular motion under the action of the drive unit, effectively increasing the spraying area of ​​the nozzle. In addition, this design is not only simple in structure but also facilitates the spraying of mold release agent onto the sidewalls of the mold cavity, especially for the inner cavity of molds for small preforms.

[0007] In some embodiments of this application, the mounting base is made into a long strip shape and also includes multiple release agent spraying units, which are spaced apart on the mounting base along its length.

[0008] This application improves the efficiency of mold release agent spraying by including multiple mold release agent spraying units in the mold release agent spraying device and installing these units at intervals along the length of the mounting base.

[0009] In some embodiments of this application, the drive unit includes an electric motor and a first transmission wheel. The electric motor is mounted on a mounting base, and the first transmission wheel is tractably connected to the power output end of the electric motor. Each transmission shaft has a second transmission wheel on its upper part, and the first transmission wheel is tractably connected to each second transmission wheel.

[0010] This application achieves better synchronization by connecting the electric motor and the first transmission wheel in the drive unit, providing a second transmission wheel on the upper part of each transmission shaft, and connecting the first transmission wheel with each second transmission wheel. This allows the electric motor to drive multiple nozzles to rotate simultaneously.

[0011] In some embodiments of this application, two second transmission wheels are spaced apart axially on the transmission shaft. Both the first and second transmission wheels are pulleys. The first transmission wheel is tractably connected to a second transmission wheel via a transmission belt. The second transmission wheels on adjacent transmission shafts are tractably connected via transmission belts. Alternatively, two second transmission wheels are spaced apart axially on the transmission shaft. Both the first and second transmission wheels are sprockets. The first transmission wheel is tractably connected to a second transmission wheel via a transmission chain. The second transmission wheels on adjacent transmission shafts are tractably connected via transmission chains.

[0012] In some embodiments of this application, the number of release agent spraying units included in the release agent spraying device is 2-10.

[0013] In some embodiments of this application, a lifting and pushing device is also included. The lifting and pushing device is installed on the support base, and the pushing and pulling end of the lifting and pushing device is arranged downwards. The mounting base is connected to the pushing and pulling end of the lifting and pushing device.

[0014] This application, by setting up a lifting and pushing device, allows the position of the release agent spraying unit in the vertical direction to be adjusted by adjusting the position of the mounting base. This enables the release agent spraying unit to be adaptively adjusted according to the height of different molds, making the release agent spraying device suitable for mold spraying of different prefabricated products and giving it good universal applicability.

[0015] In some embodiments of this application, two lifting and pushing devices are also included. The lifting and pushing devices are telescopic cylinders. The two lifting and pushing devices are installed at intervals on the support base, and the mounting bases are respectively connected to the pushing and pulling ends of the lifting and pushing devices.

[0016] In some embodiments of this application, a protective cover is also included, which is mounted on a mounting base, and the multiple nozzles of the multiple release agent spraying units are located inside the protective cover.

[0017] This application uses a protective shield to restrain the sprayed release agent, thereby reducing the environmental pollution caused by the release agent.

[0018] In some embodiments of this application, the supporting frame includes supporting columns and supporting beams, with two supporting columns spaced apart, and the supporting beams spanning across the supporting columns, and the mounting base installed directly below the supporting beams.

[0019] Secondly, this application also provides a precast component production line, including a mold transfer device and a release agent spraying device as described in any of the foregoing embodiments, wherein the running trajectory of the mold transfer device passes directly below the mounting base.

[0041] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0042] The following is based on Figures 1 to 7 This invention introduces the mold release agent spraying device and preform production line provided by this utility model.

[0043] The mold release agent spraying device provided in this application includes a support frame 1, a mounting base 2, a drive unit 3, and a mold release agent spraying unit. The mounting base 2 is connected to the support frame 1, and the drive unit 3 is mounted on the mounting base 2; specifically as follows... Figure 1 , Figure 3 and Figure 5 As shown, the mounting base 2 is located directly below the supporting frame 1. The mold release agent spraying unit is mounted on the mounting base 2. Specifically, the mold release agent spraying unit includes a drive shaft 41, a drive rod 42, and a nozzle 43. The drive shaft 41 is vertically oriented, and the drive unit 3 is connected to the upper end of the drive shaft 41. Then... Figure 2 As shown, the middle part of the drive shaft 41 is rotatably connected to the upper part of the mounting base 2, the upper end of the drive rod 42 is ball-jointed to the eccentric part of the lower end of the drive shaft 41, the middle part of the drive rod 42 is ball-jointed to the lower part of the mounting base 2, and the nozzle 43 is installed at the lower end of the drive rod 42.

[0044] In practical implementation, the middle part of the drive shaft 41 is connected to the upper part of the mounting base 2 via a bearing, so that the drive shaft 41 can rotate relative to the mounting base 2 under the drive of the drive unit 3. In addition, there are no specific restrictions on the transmission method between the drive unit 3 and the drive shaft 41. It can be transmitted through gears or gear sets, or selectively through belt drive or sprocket drive.

[0045] In this application, the upper end of the transmission rod 42 is connected to the eccentric portion of the lower end of the transmission shaft 41 via a ball joint structure to ensure the rotational freedom of the transmission rod 42. Similarly, the middle part of the transmission rod 42 is connected to the mounting base 2 via a ball joint structure.

[0046] It should be noted that the supporting frame in this application is not specifically limited; it can be any structural frame capable of supporting the release agent spraying unit and the mounting base 2. In specific implementations, the supporting frame 1 can be selectively a structural frame fixed to the foundation, or it can be a structural frame capable of moving along a predetermined path. Specifically, as shown... Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, the support frame 1 includes support columns 11 and support beams 12. Two support columns 11 are spaced apart, and the support beams 12 span across the support columns 11. The mounting base 2 is installed directly below the support beams 12.

[0047] It should also be noted that the mounting base in this application is not specifically limited; it can be any structural unit that can meet the installation and transmission requirements of the release agent spraying unit, such as... Figures 1 to 5 As shown, the mounting base 2 is a long, rectangular frame structure made of sheet metal.

[0048] The drive unit in this application is not specifically limited and can be any unit capable of driving the transmission shaft 41 to rotate; in specific implementation, the drive unit 3 is preferably a unit including an electric motor. In specific operation, the drive motor drives the transmission shaft 41 to rotate, and under the drive of the transmission shaft 41, the transmission rod 42 moves with the transmission shaft 41, thereby driving the nozzle 43 to perform circumferential motion.

[0049] This application includes a release agent spraying unit comprising a drive shaft 41, a drive rod 42, and a nozzle 43. The drive shaft 41 is further connected to the drive unit 3, with its middle section rotatably connected to the mounting base 2. The upper end of the drive rod 42 is ball-jointed to the eccentric portion of the lower end of the drive shaft 41, and the middle section of the drive rod 42 is ball-jointed to the lower part of the mounting base 2. In operation, the nozzle 43, located at the lower end of the drive rod 42, can perform circular motion under the action of the drive unit 3, effectively increasing the spraying area of ​​the nozzle. Furthermore, this design is not only simple in structure but also facilitates the spraying of release agent onto the sidewalls of the mold cavity, especially for the inner cavity of molds containing small preforms.

[0050] As some preferred embodiments of this application, such as Figures 1 to 5 As shown, the mounting base 2 is further made into an elongated shape. The mold release agent spraying device also includes multiple mold release agent spraying units, which are spaced apart on the mounting base 2 along its length. Specifically, as shown... Figure 1 , Figure 3 and Figure 5 As shown, the mold release agent spraying device includes seven mold release agent spraying units, which are spaced apart along the length of the mounting base 2. Alternatively, the number of mold release agent spraying units included in the device can be selected to be any one of 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10.

[0051] It should be noted that there is no specific limitation on the number of release agent spraying units included in the release agent spraying device; they can be selectively set according to the mold being sprayed. This application, by including multiple release agent spraying units in the release agent spraying device and installing these units at intervals along the length of the mounting base 2, effectively increases the spraying area of ​​the release agent spraying device, thereby achieving efficient spraying of the release agent.

[0052] In some preferred embodiments of this application, the drive unit 3 includes a motor 31 and a first transmission wheel 32. The motor 31 is mounted on the mounting base 2, and the first transmission wheel 32 is driveably connected to the power output end of the motor 31. Each transmission shaft 41 has a second transmission wheel 33 on its upper part, and the first transmission wheel 32 is driveably connected to each second transmission wheel 33. It should be noted that neither the first transmission wheel 32 nor the second transmission wheel 33 is specifically limited; they can be any transmission wheel that meets the transmission requirements. In specific implementations, it is preferable that both the first transmission wheel 32 and the second transmission wheel 33 are pulleys, gears, or sprockets, etc. Figure 2 and Figure 4 As shown, both the first transmission wheel 32 and the second transmission wheel 33 are pulleys, which enable the first transmission wheel 32 and the second transmission wheel 33 to be driven by the pulley (not shown in the figure).

[0053] This application enables the electric motor 31 and the first transmission wheel 32 of the drive unit 3 to be connected in a transmission connection, and provides a second transmission wheel 33 on the upper part of each transmission shaft 41, and makes the first transmission wheel 32 and each second transmission wheel 33 connectable in a transmission connection. In this way, the electric motor 31 can drive multiple nozzles 43 to rotate simultaneously, so that the nozzles 43 have better synchronization.

[0054] As some preferred embodiments of this application, such as Figure 2 and Figure 4 As shown, two second transmission wheels 33 are spaced apart axially on the transmission shaft 41. Both the first transmission wheel 32 and the second transmission wheel 33 are pulleys. The first transmission wheel 32 is tractably connected to one of the second transmission wheels 33 via a transmission belt (not shown in the figure). The second transmission wheels 33 on adjacent transmission shafts 41 are tractably connected via transmission belts (not shown in the figure). As an alternative embodiment, the first transmission wheel 32 and the second transmission wheel 33 can also be selectively sprockets. The first transmission wheel 32 is tractably connected to one of the second transmission wheels 33 via a transmission chain, and the second transmission wheels 33 on adjacent transmission shafts 41 are tractably connected via transmission chains.

[0055] As some preferred embodiments of this application, the release agent spraying device further includes a lifting and pushing device 5. The lifting and pushing device 5 is mounted on the support base 1, and the pushing and pulling end of the lifting and pushing device 5 is arranged downwards. The mounting base 2 is connected to the pushing and pulling end of the lifting and pushing device 5.

[0056] It should be noted that the "lifting and pushing device" in this application is not specifically limited, and it can be any device capable of adjusting the position of the mounting base 2 in the vertical direction. In specific implementations, the lifting and pushing device 5 can be selectively made into a telescopic cylinder, a lead screw slider linear module, a gear rack linear module, etc.

[0057] This application, by setting up a lifting and pushing device 5, can adjust the position of the release agent spraying unit in the vertical direction by adjusting the position of the mounting base 2 in the vertical direction. This allows the position of the release agent spraying unit to be adjusted adaptively according to the height of different molds, making the release agent spraying device suitable for mold spraying of different prefabricated products and having good universal applicability.

[0058] As a preferred embodiment of the foregoing implementation, such as Figure 1 , Figure 3 and Figure 5 As shown, the release agent spraying device includes two lifting and pushing / pulling devices 5. Each lifting and pushing / pulling device 5 is a telescopic cylinder, and the two devices 5 are installed at intervals on the support frame 1. Mounting seats 2 are connected to the pushing / pull ends of the lifting and pushing / pulling devices 5 respectively. During operation, the vertical position of the mounting seats 2 is controlled by controlling the telescopic cylinders.

[0059] As some preferred embodiments of this application, the mold release agent spraying device further includes a protective cover 6, specifically as follows: Figures 1 to 7 As shown, the protective cover 6 is mounted on the mounting base 2, and the protective cover 6 gradually widens from top to bottom; the multiple nozzles 43 included in the multiple release agent spraying units are located inside the protective cover 6. By setting the protective cover 6, this application can restrain the sprayed release agent, thereby reducing the pollution of the release agent to the environment.

[0060] This application also provides a precast component production line, including a mold transfer device and a release agent spraying device as described in any of the foregoing embodiments, wherein the running trajectory of the mold transfer device passes directly below the mounting base 2.
