Description

Technical Field

[0001] This invention relates to the field of plastic molding technology, and in particular to a counting knob, a die lip adjustment unit, a die lip adjustment device, and an adjustment method. Background Technology

[0002] The die lip is an adjustable component at the end of the plastic film extrusion die, directly affecting the uniformity of film thickness. The die lip generally consists of an upper lip and a lower lip. The upper lip is connected to multiple adjustment units for adjusting the gap width between it and the lower lip. Currently, these adjustment units are commonly adjusted using bolts. After technicians repeatedly rotate the adjustment bolts to achieve the ideal thickness distribution, there is a lack of reasonable methods for recording the adjustment parameters of each bolt. Most companies still rely on manual marking or paper records. This crude recording method is prone to parameter loss or misinterpretation, especially when product formulas are changed and thickness parameters need to be reset, or when restarting production after a long shutdown. This can easily lead to inaccurate resets, requiring significant time and manpower for readjustment, which is detrimental to improving production efficiency. Summary of the Invention

[0037] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0038] The following is for reference. Figures 1 to 4 The present invention describes a counting knob 200, a die lip adjustment unit, a die lip adjustment device, and an adjustment method according to embodiments thereof.

[0039] The counting knob 200 of the first aspect of the present invention, referred to Figure 3 It includes a base 201, a sleeve 211, and a second dial 220.

[0040] The base 201 is used to fix the support 300 to the die lip adjustment unit. The base 201 also serves as the housing of the counting knob 200 to protect the transmission mechanism inside the counting knob 200.

[0041] The sleeve 211 is used to fix it outside the adjusting bolt 310. The sleeve 211 is rotatably connected to the base 201. The sleeve 211 is provided with a first scale 210. With the axis of the sleeve 211 as vertical, the first scale 210 can be fixedly set on the top of the sleeve 211. The first scale 210 is set on the upper surface of the base 201. The base 201 is provided with a first zero point mark corresponding to the first scale 210. The reading of the first scale 210 can be observed from above the counting knob 200.

[0042] The second dial 220 is rotatably mounted on the base 201. The axis of the second dial 220 is vertical. A transmission mechanism is connected between the second dial 220 and the sleeve 211. The transmission ratio between the second dial 220 and the sleeve 211 is greater than one. That is, the rotational speed of the second dial 220, which is the driven component, is smaller than the rotational speed of the sleeve 211, which is the driving component, so that the recorded value range of the second dial 220 is larger than that of the first dial 210.

[0043] In use, the base 201 can be fixedly installed on the support base 300 of the die lip adjustment unit, and the sleeve 211 can be fixedly sleeved on the adjusting bolt 310 of the die lip adjustment unit. The adjustment parameters of the adjusting bolt 310 can be accurately displayed by the first dial 210 and the second dial 220. When the process debugging reaches the ideal state, the operator can simultaneously record the readings of each counting knob 200 and associate them with the process formula parameters to form a traceable benchmark database. When it is necessary to reproduce a specific process, it is only necessary to retrieve the corresponding position parameters of the adjusting bolt 310, and the adjustment and reset can be quickly completed according to the readings of the counting knob 200.

[0044] In some embodiments of the present invention, the second dial 220 is annular and coaxial with the sleeve 211. The second dial 220 is rotatably fitted onto the outside of the sleeve 211, thus allowing smooth rotation of the second dial 220. The second dial 220 is located on the lower side of the sleeve 211, and the scale lines of the second dial 220 are set on its outer periphery. An observation window is provided on the front side of the base 201 corresponding to the second dial 220 to facilitate observation of the scale of the second dial 220. A second zero-point mark corresponding to the second dial 220 is provided on the front side of the base 201, and the reading of the second dial 220 can be observed from the front side of the technical knob.

[0045] In some embodiments of the present invention, reference is made to... Figure 4 The transmission mechanism includes a first gear 212 mounted on the sleeve 211, a second gear 222 mounted on the second dial 220, and a third gear 232 rotatably mounted on the base 201. All three gears are located within the base 201. All three are external gears. The first gear 212 and the second gear 222 are coaxial, while the third gear 232 is vertically positioned on the right rear side of the sleeve 211. The upper and lower parts of the third gear 232 mesh with the first gear 212 and the second gear 222, respectively. The first gear 212 is an incomplete gear. This arrangement results in the first gear 212 and the second gear 222 overlapping axially, creating a reasonable and compact structure that facilitates installation onto the adjusting bolt 310.

[0046] In some embodiments of the present invention, the number of teeth of the second gear 222 is ten times the number of teeth of the first gear 212. Thus, when the first dial 210 rotates ten times, the second dial 220 rotates one time, and the counting knob 200 can visually display the rotation amount from 0 to 9.9 revolutions.

[0047] The mold lip adjustment unit of the second aspect embodiment of the present invention, referred to Figure 2The system includes a support base 300, an adjusting bolt 310, an adjusting nut 330, a pull rod 340, and the aforementioned counting knob 200. The adjusting nut 330 is fixedly mounted on the support base 300, and the adjusting bolt 310 is threadedly connected to the adjusting nut 330. The pull rod 340 is coaxial with the adjusting bolt 310, and one end of the adjusting bolt 310 is rotatably connected to the pull rod 340. The pull rod 340 is used to connect the adjusting bolt 310 and the upper lip 101 of the mold lip. The base 201 is fixedly mounted relative to the support base 300, and the sleeve 211 is fixedly fitted onto the adjusting bolt 310. Specifically, the sleeve 211 is fixedly fitted onto the end of the adjusting bolt 310 away from the pull rod 340, and the adjusting bolt 310 protrudes from the sleeve 211 to facilitate manual rotation adjustment.

[0048] By setting the counting knob 200, the adjustment parameters of the adjusting bolt 310 can be accurately displayed by the first dial 210 and the second dial 220. When the die lip adjustment unit needs to be reset, the adjustment and reset can be quickly completed according to the reading of the counting knob 200.

[0049] The die lip adjustment device according to a third aspect of the present invention, referring to Figure 1 The device includes a die lip component 100 and a plurality of the aforementioned die lip adjustment units. The die lip component 100 has a main body, an upper lip 101 and a lower lip, with the upper lip 101 positioned above the lower lip. The upper lip 101 extends laterally, and the plurality of die lip adjustment units are arranged sequentially along the extension direction of the upper lip 101. The support base 300 is fixedly disposed relative to the main body, and the pull rod 340 is connected between the adjustment bolt 310 and the upper lip 101.

[0050] By setting up multiple die lip adjustment units as described above, when a specific process needs to be reproduced, it is only necessary to retrieve the position parameters of the adjustment bolt 310 of the corresponding die lip adjustment unit, and then quickly complete the adjustment and reset of each die lip adjustment unit according to the reading of the counting knob 200, thereby quickly completing the adjustment of the die lip.

[0051] In some embodiments of the present invention, the main body is provided with a translation seat 110 and a first driver 111 for driving the translation seat 110 laterally, with the axial direction of the adjusting bolt 310 as the first direction. The translation seat 110 is provided with a lifting seat 120 and a second driver 121 for driving the lifting seat 120 along the first direction. The lifting seat 120 is provided with a rotary driver 131. The drive shaft of the rotary driver 131 is provided with a cutter head for rotating the adjusting bolt 310. The cutter head is detachably connected to the adjusting bolt 310. The first driver 111 can be a linear motor or a rotary motor driving a lead screw and nut pair. Specifically, the first driver 111 includes a first guide rail extending laterally, a first slider slidably disposed on the first guide rail, a first motor, and a first lead screw and nut pair. The first guide rail is fixedly disposed on the main body, and the first slider is disposed on the translation seat 110 to achieve a sliding connection between the translation seat 110 and the main body. The first lead screw and nut pair includes a first lead screw and a first nut. The first lead screw is laterally disposed and rotatably disposed on the main body. The drive shaft of the first motor is coaxial with and linked to the first lead screw. The first nut is fixedly disposed on the translation seat 110. Therefore, starting the first motor drives the translation seat 110 to move laterally. The second driver 121 is similar; it can also be a linear motor or a rotary motor driving a lead screw and nut pair. This allows for the adjustment of the adjusting bolts 310 of each die lip adjustment unit via electronic control, facilitating more precise adjustment.

[0052] In some embodiments of the present invention, the cutting head is a hexagonal cutting head 132, and the adjusting bolt 310 is provided with a hexagonal groove adapted to the hexagonal cutting head 132. In this way, the connection between the hexagonal cutting head 132 and the adjusting bolt 310 can be achieved by insertion connection, which is simple in structure and the separation and engagement between the hexagonal cutting head 132 and the adjusting bolt 310 is smooth.

[0053] In some embodiments of the present invention, the die lip adjustment unit further includes an encoder 320, which includes a rotor disposed on the adjusting bolt 310 and a stator disposed on the support base 300; the die lip adjustment device includes a controller, and the encoder 320, the first driver 111, the second driver 121, and the rotary driver 131 are all electrically connected to the controller, which has a storage module. By setting the encoder 320 and the controller, the die lip adjustment device can automatically reset each die lip adjustment unit, which is beneficial for realizing automated production.

[0054] A multi-turn absolute encoder 320 is integrated into each adjusting bolt 310. By monitoring the rotation angle and number of turns of the adjusting bolt 310 in real time, the mechanical displacement is accurately converted into a digital signal and transmitted to the controller via an industrial bus. The high-precision encoder 320 used has an angular resolution of ±0.05°, which ensures that the system achieves micron-level displacement control accuracy.

[0055] The mold lip adjustment method according to a fourth aspect of the present invention uses the above-described mold lip adjustment device to adjust the mold lip. The mold lip adjustment method includes an adjustment method and a reset method. The adjustment method includes:

[0056] In step S100, multiple adjusting bolts 310 are manually rotated to ensure that the thickness distribution of the die lip meets the requirements.

[0057] Step S200: Obtain the encoded data of each encoder 320 and store it in the controller's storage module;

[0058] Reset methods include:

[0059] In step S300, the first driver 111 and the second driver 121 are controlled to drive the translation seat 110 and the lifting seat 120, so that the cutter head is connected to the adjusting bolt 310 of the target die lip adjusting unit.

[0060] Step S400: Obtain the current encoding data of the encoder 320 of the target mold lip adjustment unit;

[0061] In step S500, the rotary driver 131 is controlled to drive the cutter head so that the current encoded data of the target die lip adjustment unit is consistent with the encoded data in the storage module.

[0062] By setting up the encoder 320 and the controller, when the die lip needs to be reset, the controller can control the first driver 111, the second driver 121 and the rotary driver 131 to reset the die lip adjustment unit one by one, without the need for manual adjustment and reset, which is beneficial to improving production efficiency.

[0063] The die lip adjustment device can be manufactured from existing devices by adding components, offering advantages such as simple production, low cost, and ease of promotion. In use, each die lip adjustment unit can be manually adjusted according to real-time conditions during production, or automatically reset via electronic control. This embodiment combines ease of operation and cost-effectiveness, avoiding the drawbacks of traditional manual marking methods that are prone to loss and misreading, while overcoming the high cost and complex maintenance of electronic systems. Operators can perform coarse adjustments without specialized measuring tools, significantly reducing reliance on technical experience. Simultaneously, this solution retains compatibility with traditional operating methods, laying a data foundation for subsequent full digital upgrades, making it an ideal choice for the transition of die lip gap adjustment technology from traditional mechanical to modern digital. In practical applications, this transitional technology not only solves the core pain point of low reset efficiency but also provides a reliable guarantee for the stable reproduction of production processes by establishing a standardized parameter recording system.

[0064] In some embodiments of the present invention, the controller may not have a storage module. Instead, each die lip adjustment unit includes a storage unit and a first signal transmission unit. The lifting base 120 of the die lip adjustment device is provided with a second signal transmission unit adapted to the first signal transmission unit. When the cutter head is connected to the adjusting bolt 310 of the current die lip adjustment unit, the first signal transmission unit is electrically connected to the second signal transmission unit of the current die lip adjustment unit. When the cutter head is separated from the adjusting bolt 310 of the current die lip adjustment unit, the first signal transmission unit is disconnected from the second signal transmission unit of the current die lip adjustment unit, and the signal receiving unit is electrically connected to the controller. The first and second signal transmission units can both be wireless transmission units, or both can be quick connectors.

[0065] In this embodiment, the debugging method includes:

[0066] In step S600, multiple adjusting bolts 310 are manually rotated to ensure that the thickness distribution of the die lip meets the requirements.

[0067] In step S700, the first driver 111 and the second driver 121 are controlled to drive the translation seat 110 and the lifting seat 120, so that the cutter head is connected to the adjusting bolt 310 of the target die lip adjusting unit.

[0068] Step S800: Obtain the encoded data of the encoder 320 of the target die lip adjustment unit and store it in the storage unit of the target die lip adjustment unit;

[0069] Reset methods include:

[0070] In step S900, the first driver 111 and the second driver 121 are controlled to drive the translation seat 110 and the lifting seat 120, so that the cutter head is connected to the adjusting bolt 310 of the target die lip adjusting unit.

[0071] Step S1000: Obtain the current encoding data of the encoder 320 of the target mold lip adjustment unit and the encoding data in the storage unit;

[0072] Step S1100: Control the rotary driver 131 to drive the cutter head so that the current encoded data of the target die lip adjustment unit is consistent with the encoded data in the storage unit.

[0073] The coded data used to reset the current die lip adjustment unit is stored in the current die lip adjustment unit. When a die lip adjustment unit is damaged, only the damaged die lip adjustment unit needs to be replaced and debugged, avoiding changes or interference to the reset data of all die lip adjustment units. This avoids the problem of large-scale data errors that would require staff to spend a lot of time manually debugging all die lip adjustment units again.

[0074] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
