Description

Technical Field

[0001] This invention belongs to the field of caster wrapping technology, and specifically relates to an automatic wrapping device for heat shrinking and winding. Background Technology

[0002] Commercially available casters, designed for weight reduction, shock absorption, corrosion resistance, and high / low temperature tolerance, typically have a rubber coating on metal or other substrates. These coatings come in various materials, including PVC, nylon, PU, ​​TPR, and rubber. During production and sales, these materials inevitably suffer damage or become soiled. Therefore, a dustproof film is applied after the caster is manufactured to prevent surface scratches. Currently, a manual, assisted positioning method is commonly used. After the film is wrapped around the wheel, a heating device is used to thermoplasticize the film, completing the wheel's coating.

[0003] Currently, traditional manual production is time-consuming and prone to inaccurate positioning due to low precision. Inaccurate positioning can lead to incomplete wrapping of some products, which may affect the appearance of the wheels before shipment and thus affect the delivery. The temperature of the thermoplastic part may also cause injury to the workers, posing certain safety risks.

[0004] In summary, we hope to propose a new structure to solve the aforementioned technical problems. Summary of the Invention

The entire operation process breaks down the manual steps in the existing technology and replaces them with mechanical actions, which improves the operation accuracy, effectively increases production efficiency and yield, and effectively reduces safety risks in the production process.

[0020] By configuring the frame, turntable assembly, and heat shrink assembly, and specifically designing the adjustment guide groove for different caster sizes used in existing technologies, the heating equipment can be precisely rotated and finely adjusted simultaneously via the cooperation of the adjustment guide shaft and the adjustment guide groove during linear movement. This ensures that the heating equipment covers the preset heating area without preheating the casters being wrapped or causing heating deviations for casters requiring heat shrinking. Furthermore, the heat shrink assembly is equipped with a start / stop mechanism that activates and stops the heating equipment only at the preset starting position, specifically improving the use of continuous heating equipment in existing technologies and reducing unnecessary waste.

[0049] After the casters at the wrapping station 206 are wrapped with film, the cutting and clamping cylinder 705 pushes the clamping pusher 706 to move to the rear, and the clamping connecting rod 708 pushes the clamping seat 709 to rotate, so that both the upper and lower clamping seats 709 rotate 90°. Then, the two sets of clamping plates 711 clamp the upper and lower ends of the packaging material. After clamping, the two sets of staggered cutting blades 712 cut the packaging material. Then, the clamping plate 711 is controlled to move to the right to complete the half-circle wrapping of the other set of casters.

[0050] Spring parameter selection table Specifically, during the wrapping and protection process for casters, the user installs the required packaging material onto the outside of the packaging material installation roller 302, and then pulls it first, passing it over the left auxiliary roller 303 and the right auxiliary roller 303 in sequence. The right auxiliary roller 303 is held and positioned by the pressure roller 304 set above. The caster is installed by the user at the wrapping station 206. After the packaging material is pulled, the caster installed above is wrapped around it half a turn. In the subsequent wrapping process, automatic pulling and wrapping can be achieved. After the user completes the pre-installation of the packaging material, the equipment is started. The lifting frame 502 controls the wrapping frame 503 to move closer to the wrapping station 206, and the rotating frame 504 drives the pressure transmission roller 505 to rotate. Due to the contact between the pressure transmission roller 505 and the caster, power transmission is achieved, which drives the caster to achieve the subsequent automated wrapping of the packaging material. Before the packaging material wraps around the casters, the equipment controls the pressure rod to push the cylinder 401 to move, which in turn moves the pressure rod mounting plate 403 forward toward the casters. Its linear movement is also assisted by the through-mounted pressure guide rod 405. The movement of the pressure rod mounting plate 403 will synchronously drive the four sets of pressure rods 404 to move, so that the front end of the pressure rod 404 presses and limits the casters to prevent the casters from deviating during the packaging material wrapping process. The pressure cylinder 602 is also controlled by the PLC to move the pressure slider 604 along the pressure slide rail 603, which in turn controls the auxiliary pressure wheel seat 605 to move closer to the casters, so that the wheel part in the auxiliary pressure wheel seat 605 assists in pressing the packaging material. After the packaging material is covered by the upper casters, the PLC controls the cutting and clamping cylinder 705 to move, causing it to move the clamping pusher 706 backward. This, via the rotating clamping connecting rod 708, pushes the clamping seat 709 to rotate around the axis connecting to the rotating seat 707. This causes both sets of symmetrically arranged clamping seats 709 to rotate 90°, thus aligning the two sets of clamping plates 711 parallel to each other above and below the packaging material. The two sets of clamping plates 711 then clamp the packaging material. Due to the release spring 710, after the initial clamping of the packaging material, the two sets of clamping plates 711 continue to move towards each other. The two sets of staggered cutting blades 712 complete the cutting of the packaging material. After the cutting is completed, the moving cylinder 702 will drive the moving slider 704 to move to the right via the moving link 703, pulling the first part of the packaging material to the right. Before this operation, because the upper caster is covered, the pressure mold transmission roller 505 moves away from the caster to make room for movement and prevent interference. The packaging material cutting component 700 is located in the suspended part of the packaging material. After the packaging material is wrapped around the caster, it is cut in the suspended section, which will not accidentally damage the packaging material wrapped to the outside of the caster, making the protective performance of the wrapped caster better. Secondly, the shifting motor 202 controls the drive gear 203 to rotate, and in the meshing structure, the driven gear 204 drives the turntable body 205 to rotate 180°, so that the two sets of wrapping stations 206 switch positions. The rotation of the turntable body 205 will be connected through the material pressing guide rod 405, and drive the pressure rod mounting plate 403 to rotate along with the material pressing rotating seat 402. After the wrapping station 206 is switched, the clamping plate 711 releases the clamping of the packaging material, so that the bottom of the plate covers the caster half a circle, forming a pre-operation of automated wrapping of the packaging material. After the turntable body 205 completes one rotation, the pressure rod 404 is released and retracted. The casters switched to the lower position will be thermoformed by the activated heating equipment 825, so that the packaging material completely covers the outside of the casters. After the casters are thermoformed, the ejector cylinder 901 will drive the ejector rod 902 to move backward, which will push the casters to move backward and detach the casters from the wrapping station 206. Before this operation, the moving discharge cylinder 1003 will also drive the moving material trough 1004 to move to the left, so that the moving material trough 1004 is set below the wrapping station 206 to receive the ejected casters. Then, the moving material trough 1004 will be controlled to move to the right and retract. The above operations achieve the installation, wrapping, thermoforming, and unloading of casters, and this process is repeated. The wrapping and thermoforming operations of casters can be carried out simultaneously to a certain extent. The overall operation process breaks down the manual steps in the existing technology and replaces them with mechanical actions, which relatively improves the operation accuracy, effectively improves the production efficiency and yield, and effectively reduces the safety risks in the production process.

The rotating seat 808 is a rotating structure connected to the transverse slider 824. The adjusting guide groove 804 is opened on the rear side of the transverse slider 802. The adjusting guide shaft 805 is a movable fitting structure set inside the adjusting guide groove 804. The linkage rod 806 is located on the rear side of the adjusting guide shaft 805 and is used to adjust the guide shaft 805 to different positions in the adjusting guide groove 804 to drive the rotating seat 808 to rotate. The lower end of the linkage rod 806 is set to the rear and is linked to the rotating seat 808. The rotary torsion spring 807 is set on the outer side of the lower rear end of the linkage rod 806 and is used to drive the linkage rod 806 to rotate.

The linkage seat plate 809 is located on the right rear side of the heat shrink bracket 801, the abutting arc seat 810 is located on the right side of the linkage seat plate 809, the linkage column 813 is three sets of circumferentially distributed and located on the left side of the linkage seat plate 809, the linkage column 813 is located on the left side of the linkage seat plate 809, and the disconnecting spring 814 is located on the left side of the linkage column 813.

The two sets of positioning grooves 819 are arranged symmetrically on the rear side of the transition groove 818.

The positioning seat 820 is a movable fitting structure coaxially arranged on the rear side of the transition groove 818. The push column 821 is arranged on the rear side of the positioning seat 820. Two sets of third electrode plates 826 are symmetrically fixed structures arranged on the outside of the push column 821.

The first electrode plate 815, the second electrode plate 817 and the third electrode plate 826 are all U-shaped elastic electrode plates. The first electrode plate 815 and the second electrode plate 817 are electrically connected by a cable 816. A positioning spring 823 is also sleeved on the outside of the push post 821. A push seat 822 is provided on the rear side of the push post 821. Two first electrode plates 815 are connected in series to form a first control loop, and the second electrode plate (817) and the third electrode plate (826) form a second control loop. The two loops use series logic to control the on and off of the heating device 825. When the trigger head 207 is pressed down to abut against the arc seat 810, the first electrode plate 815 closes. At the same time, the second electrode plate 817 and the third electrode plate 826 must be in contact to form a complete circuit.

[0054] The outer side of the positioning seat 820 is symmetrically connected with two sets of positioning blocks, which are used to rotate 90° and embed into the positioning groove 819 when the positioning seat 820 is located in the transition groove 818. At this time, the second electrode plate 817 and the third electrode plate 826 are in electrical contact. Adjustment grooves 811 are provided at both ends of the abutment arc seat 810. The adjustment arc seat 812 is movably fitted inside the adjustment groove 811 and is fixed after adjustment by bolts. It is used to adjust the contact stroke between the trigger head 207 and the abutment arc seat 810 to change the power-on working range of the heating device 825.

[0055] In this embodiment, the heating device 825 is a hot air circulation heating device or an infrared heating device, and the heating temperature control range of the heating device 825 is 120℃~180℃, preferably 140℃~160℃. The heating time should be controlled between 2 and 6 seconds; When the packaging material is PVC, the preferred heating temperature is 130℃~150℃; When the packaging material is POF, the preferred heating temperature is 150℃~170℃; The rotational speed of the film pressing drive roller 505 is 30-80 rpm, preferably 40-60 rpm; The packaging material tension is controlled at 5–20 N, which is achieved through the coordinated action of the pressure roller 304 and the auxiliary pressure wheel seat 605.

[0056] The material ejection cylinder 901 and the moving discharge cylinder 1003 are both automatically controlled by the PLC built into the frame 100.

[0057] To address the different caster specifications used in existing technologies, the adjusting guide groove 804 is specifically designed so that the heating device 825 can be rotated and finely adjusted synchronously during linear movement via the cooperation of the adjusting guide shaft 805 and the adjusting guide groove 804. This ensures that the heating device 825 covers the preset heating area without preheating the casters being wrapped or causing heating deviations for casters requiring heat shrinking. Furthermore, the heat shrink assembly 800 is also equipped with a start / stop mechanism that activates and stops the heating device 825 only at the preset starting position. This specifically improves the use of the all-time heating device 825 in existing technologies, reducing unnecessary waste.

[0058] Based on the first embodiment described above, furthermore, casters on the market have different specifications, and the range of thermoforming for commonly available casters varies (i.e., when the caster is installed at the wrapping station 206, the heating device 825 may have incomplete or offset coverage due to different specifications). By providing an adjustment guide groove 804 behind the transverse slide block 802, the adjustment screw 803, under manual rotation control, drives the transverse slide block 824 to move left and right, and in doing so, drives the adjustment guide shaft 805 to move accordingly. This ensures that the adjustment guide shaft 805 moves synchronously within the adjustment guide groove 804, and the combined action of both allows for adjustment... The guide shaft 805 drives the linkage rod 806 to rotate, which in turn drives the rotating seat 808 to rotate and fine-tune. This allows the heating device 825 to rotate accordingly, achieving synchronous adjustment of linear movement and rotation. After adjustment, the heating device 825 can be in different positions and orientations to accommodate the thermoplastic use of casters of the current specifications. (In the setting of the adjustment guide groove 804, it is specifically set to match the movement distance and caster specifications. For example, a movement distance of 20mm is matched with 5-inch casters. The setting of the adjustment guide groove 804 causes the linkage rod 806 to rotate 2°. At this time, the heat source outlet of the heating device 825 effectively covers the casters.) Secondly, in the automation setting based on the first embodiment above, the present invention also specifically provides a start-stop structure for the heating device 825. This differs from the normal operation setting of the heating device 825 in the prior art. As the trigger head 207 rotates with the turntable body 205, it enters the setting area of ​​the abutting arc seat 810. The trigger head 207 presses the abutting arc seat 810 and compresses the disconnecting spring 814 through the linkage column 813, causing the two sets of first electrode plates 815 to move closer together, thus completing the circuit conduction here. In order to accommodate the different coverage range of the heating device 825, the adjusting arc seat 812 moves inside the adjusting groove 811 and is fixed by bolts after adjustment, which is compatible with the thermoplastic use of the current caster. The above-described structure allows the heating device 825 to be activated only when needed. For example, during the rotation of the turntable body 205 to switch the positions of the two sets of wrapping stations 206, it does not need to work for a period of time. Before the casters complete the thermoplastic unloading, the turntable body 205 will continue to rotate 5°, causing the trigger head 207 to move out of the area of ​​the abutting arc seat 810 and the adjusting arc seat 812. The return spring 814 contacts the two sets of first electrode plates 815, cutting off the conductive circuit of the heating device 825. At this time, the heating device 825 will no longer work. Thus, the heating device 825 stops working during the unloading process after the casters complete thermoplastic unloading and during the wrapping station 206 for the next set of casters. This reduces the waste of electrical energy during this process and avoids the problem of burns to operators that may occur due to the operation of the heating device 825. The conduction circuit of the heating device 825 is also controlled by another set of on / off structures. That is, the start and stop control of the heating device 825 is realized based on dual control. This on / off structure only requires the user to press the push seat 822 forward and rotate it 90° after it moves forward into place. Then, the external force is removed, and the positioning block is embedded into the positioning groove 819 under the action of the rebound force of the positioning spring 823. At this time, due to the linkage movement of the push column 821, it can drive the two sets of third electrode plates 826 to move along, so that the third electrode plate 826 contacts the second electrode plate 817, thus completing the conduction of the circuit here. The above-mentioned structure optimizes the start-stop control of the heating device 825, making the heating device 825 more suitable for the area of ​​caster thermoforming, eliminating unnecessary excessive coverage leading to heat waste, and insufficient coverage preventing effective thermoforming of the caster. It also eliminates the problem in the prior art where the heating device 825 is always in working state, which would result in the same operation during non-thermoforming periods, an unnecessary waste of heat source and electrical energy. Furthermore, because the heating device 825 is always in working state, it may cause certain safety hazards to the user during the unloading and loading of casters. The configuration of Embodiment 2 of the present invention can effectively solve this problem. Compared with the prior art, the present invention, by setting a mechanical linkage triggering structure between the trigger head 207 and the abutting arc seat 810, enables the heating device 825 to be powered on and operated only within a preset angle range, so that the heating time window is precisely matched with the coating station position. Compared to traditional continuous heating methods, this invention can reduce energy consumption by about 30%, while avoiding heating of non-processing areas and improving operational safety. Meanwhile, by adjusting the spatial coupling structure between the guide groove 804 and the guide shaft 805, the adaptive matching between the posture of the heating equipment and the size of the casters is achieved, thereby improving the uniformity of heat shrinkage.
