[0041] Embodiment 1
[0042] The bottom cover on the prefabricated production line is usually wrapped with plastic film. The operator needs to manually tear off the film before putting it on. Since the operator needs to wear gloves when working, it is laborious and inconvenient to tear off the film. The time wasted in tearing off the film will affect the subsequent supply of the bottom cover, thus affecting production efficiency. In addition, if the manual film tearing is not standardized, there is a risk of foreign matter being introduced, which will affect product quality.
[0043] In view of this, an embodiment of the utility model provides a bottom cover plastic film ring cutting device, including: a ring cutting bracket 100, a driving element, a control element and a cutter 200. The bottom of the ring cutting bracket 100 is open and adapted to the bottom cover. The driving element is installed in the ring cutting bracket 100. The cutter 200 is connected to the end of the driving element and can rotate and perform ring cutting under the action of the driving element. The control element is connected to the driving element signal.
[0044] When performing circular cutting, the bottom cover wrapped with the plastic film is placed at the opening at the bottom of the circular cutting bracket 100 for fixing, and the control element is operated so that the control element transmits a start signal to the driving element, and the cutter 200 rotates under the action of the driving element and circularly cuts the plastic film. Compared with the existing manual film tearing method, the use of the bottom cover plastic film circular cutting device for film cutting greatly reduces the workload of the operator, and the film cutting is convenient and fast, which improves the production efficiency, eliminates the risk of foreign matter introduction, and ensures the product quality.
[0045] In an optional manner of this embodiment, the annular stent 100 is columnar, the driving element penetrates the annular stent 100 axially, and the top of the driving element is arranged at the center of the top surface of the annular stent 100 .
[0046] See also Figure 1 The ring cutting bracket 100 is a cylindrical structure, and the bottom opening is adapted to the outer contour size of the bottom cover to be torn off. The bottom cover wrapped with the plastic film is placed at the opening at the bottom of the ring cutting bracket 100 to achieve fixation. The top of the driving element is located at the center of the top surface of the ring cutting bracket 100, and the driving element axially penetrates to the bottom of the ring cutting bracket 100. The driving element rotates to drive the cutter 200 to rotate and ring cut the plastic film.
[0047] In an optional manner of this embodiment, the driving element includes a rotating cylinder 300, a cutter 200 is connected to the end of the rotating cylinder 300, and the rotating cylinder 300 can drive the cutter 200 to rotate within a range of 180 degrees.
[0048] See also Figure 2 The driving element adopts a rotary cylinder 300 with a simple structure and reliable operation. The cutter 200 is installed at the end of the rotary cylinder 300. The rotary cylinder 300 drives the cutter 200 to rotate within a range of 180 degrees by rotating, thereby realizing the circular cutting of the plastic film.
[0049] Of course, the driving element can also adopt a driving shaft or other similar driving structure, and the rotation angle range of the cutter 200 can also be larger or smaller, as long as the rotation of the driving element can drive the cutter 200 to rotate synchronously within a certain range of angles to achieve circular cutting of the plastic film, which will not be repeated here.
[0050] In an optional manner of this embodiment, a circular cutting track 110 adapted to the cutter 200 is provided at the bottom of the circular cutting bracket 100 , and the arc of the circular cutting track 110 is 180 degrees.
[0051] See also Figure 2 Since the rotary cylinder 300 drives the cutter 200 to rotate within a range of 180 degrees by rotating, the arc of the circular cutting track 110 is also set to 180 degrees, i.e., half a circle, to maintain synchronization. The circular cutting track 110 is arranged inside the circular cutting bracket 100 to ensure that the tip of the cutter 200 is set at the groove of the bottom cover, and the bottom cover will not be scratched by scratching other parts of the bottom cover, such as the protrusion.
[0052] It should also be noted that, due to the different product models, the diameter of the bottom cover also varies, so the cutter 200 can be set as a retractable structure, such as Figure 3 As shown, a spring is provided at the end of the cutter 200 to achieve radial expansion and contraction of the cutter 200. Correspondingly, the width range of the circular cutting track 110 becomes larger and is configured to match the expansion and contraction distance of the cutter 200. The retractable cutter 200 and the circular cutting track 110 with a larger width can make the bottom cover plastic film circular cutting device suitable for bottom covers of different models, thereby improving practicality.
[0053] In an optional manner of this embodiment, a handle 120 is installed on the top of the circumcision bracket 100 , and the control element is arranged on the handle 120 .
[0054] See also Figure 1 The handle 120 is arranged across the top surface of the ring cutting bracket 100. The handle 120 and the ring cutting bracket 100 are an integrated structure. The handle 120 may be provided with an anti-slip structure such as a convex strip. The arrangement of the handle 120 facilitates the operator to extract and move the ring cutting bracket 100. The arrangement of the control element on the handle 120 facilitates the operator to control the cutter 200 in real time.
[0055] In an optional manner of this embodiment, the control element includes a solenoid valve 400, and the solenoid valve 400 is signal-connected to the driving element.
[0056] The control element adopts the electromagnetic valve 400, which has a simple structure and reliable control. The electromagnetic valve 400 can control the start and stop of the driving element through a signal, thereby realizing the control of the start and stop of the cutter 200 cutting the plastic sealing film.
[0057] Preferably, in this embodiment, the solenoid valve 400 is a manual inching solenoid valve 400. The action of the rotating cylinder 300 is realized by manually inching the solenoid valve 400. The solenoid valve 400 does not need to be connected to a power source or a signal source. The solenoid valve 400 is fixed on the handle 120 of the ring cutting bracket 100, and the solenoid valve 400 can be pressed when in use.
[0058] In an optional manner of this embodiment, a limited position sealing component is provided inside the circumcision stent 100 .
[0059] The limiting sealing component can limit the depth of the cutter 200 penetrating the plastic film, thereby preventing the cutter 200 from scratching the bottom cover; at the same time, it can enable the circular cutting operation to be performed in a relatively sealed environment, thereby preventing the introduction of foreign matter.
[0060] Specifically, the limiting sealing assembly includes a limiting ring 500 arranged along the circumferential direction, and the limiting ring 500 is used to limit the depth of the cutter 200 penetrating into the plastic film.
[0061] See also Figure 1 and Figure 2 The limiting ring 500 installed circumferentially inside the ring cutting bracket 100 can ensure that the depth of the cutter 200 penetrating the plastic film is less than a certain range such as 1 mm, so that the cutter 200 will not scratch the bottom cover due to excessive penetration into the plastic film during ring cutting.
[0062] Furthermore, the limiting sealing assembly also includes a sealing ring disposed at the limiting ring 500 , and the sealing ring abuts against the inner wall of the ring cutting bracket 100 .
[0063] The sealing ring abuts against the inner wall of the circumcision bracket 100 , so that the circumcision bracket 100 is always in a sealed state during the circumcision operation, preventing the introduction of foreign matter and eliminating the risk of the cutter 200 scratching personnel.
[0064] The following is a brief description of the use of the bottom cover plastic film ring cutting device:
[0065] When performing the ring cutting, the bottom cover wrapped with the plastic film is placed at the opening at the bottom of the ring cutting bracket 100 for fixing, and the solenoid valve 400 is manually operated to transmit a start signal to the rotating cylinder 300, and the cutter 200 rotates under the action of the rotating cylinder 300 and performs the ring cutting on the plastic film. After the ring cutting is completed, the solenoid valve 400 is manually operated to transmit a stop signal to the rotating cylinder 300, and then the handle 120 is lifted and the ring cutting bracket 100 is removed from above the bottom cover after the ring cutting is completed.
[0066] This application adopts a bottom cover plastic film circular cutting device for film cutting. Compared with the existing manual film tearing method, it greatly reduces the workload of operators. Film cutting is convenient and fast, which improves production efficiency, eliminates the risk of introducing foreign matter, and ensures product quality. It is worthy of promotion on prefabrication production lines.
[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
