[0030] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of the present application.

[0031] The core of the present application is to provide an automatic surface-pasting material tearing device for realizing the tearing of surface-pasting materials and reducing the labor cost.

[0032] Please refer to Figure 1 and Figure 2 , Figure 1 A schematic view of the automatic surface-pasting material tearing device provided by the present application is shown in FIG. 1. Figure 2 A structural schematic view of the material tearing mechanism provided by the present application is shown in FIG. 2.

[0033] The present application provides an automatic surface-pasting material tearing device, which is suitable for surface-pasting material tearing operation and provides a safe and labor-saving operation device for operation personnel. The automatic surface-pasting material tearing device includes a material tearing mechanism 1, and the material tearing mechanism 1 includes:

[0034] a housing;

[0035] a positioning mechanism rotatably arranged outside the housing and used for abutting and positioning a workpiece to be torn;

[0036] a rolling mechanism rotatably arranged in the housing and used for driving the movement of a free end of the material to be torn through rotation;

[0037] a guide wheel 8 rotatably arranged in the housing and fixedly arranged opposite to a rotating shaft of the rolling mechanism to guide the movement of the material to be torn.

[0038] It should be noted that the shell is a bearing structure of the material tearing mechanism 1, the positioning mechanism and the winding mechanism are arranged in the shell to form an integral structure. The positioning mechanism is a structure for abutting and positioning the torn workpiece, which can be a support such as an abutting plate. In further embodiments, when the material tearing mechanism 1 needs to move along the surface of the torn workpiece, the positioning mechanism can be a fixed pulley structure arranged on the shell.

[0039] The winding mechanism is arranged inside the shell and is used to pull or wind the material to be torn off, so that the material to be torn off is detached from the surface of the torn workpiece. For example, the winding mechanism can be a winding mechanism. When the end of the material to be torn off is fixed to the winding mechanism and the winding mechanism is controlled to rotate, the material to be torn off can be wound on the winding mechanism to form a circumferential accumulation so as to be detached from the torn workpiece. The winding mechanism can be a manual device, preferably an automatic device, such as a winding mechanism driven by a motor.

[0040] Alternatively, the traction of the material to be torn off can also be achieved by two or more relative rotating structures to make it fall off.

[0041] The guide wheel 8 is a structure with guiding function. Since the material to be torn off is torn on the surface of the torn workpiece, the position of the material to be torn off relative to the winding mechanism will change, which will cause inaccuracy of the position, even cause jamming or falling off. Therefore, the guide wheel 8 is arranged at the front end of the winding mechanism, i.e. between the winding mechanism and the torn workpiece. The guide wheel 8 can be a fixed pulley or a movable pulley to adjust the direction of the incoming material to be torn off and avoid winding the material.

[0042] The surface-pasted material automatic tearing device provided in the present application realizes the tearing of the material to be torn off pasted on the surface of the torn workpiece by arranging the material tearing mechanism 1. Since the winding mechanism is provided, the tearing can be realized by winding, which greatly reduces the difficulty of manual operation. In the process of tearing the surface-pasted material, the force is uniform, which can significantly reduce the labor cost, save time and labor, and is easy to operate when the motor drives the winding mechanism to run.

[0043] On the basis of the above embodiments, the winding mechanism comprises:

[0044] The motor 7;

[0045] The gear mechanism 9 has at least two gears, the gears are connected with the output end of the motor 7, and the two gears are arranged in meshing mode to drive the movement of the material to be torn off.

[0046] Please refer to Figure 2The gear mechanism 9 has at least two gears which are arranged in meshing relationship and can place the free end of the material to be torn in the meshing position of the two gears during rotation, so that the two gears form traction to the material to be torn or form winding on at least one gear.

[0047] The gear mechanism 9 is driven to rotate by the motor, and the rotation can be adjusted in speed or direction by a speed reducer.

[0048] The motor 7 is preferably a variable-speed motor, which can adjust the tearing speed according to the state or position of the material to be torn during use.

[0049] Considering that the relative position between the material tearing mechanism 1 and the material to be torn can change during tearing, the positioning mechanism can be a movable positioning mechanism, for example, the positioning mechanism includes at least two positioning wheels 6, and the shafts of the positioning wheels 6 are fixed to the housing.

[0050] The material tearing mechanism 1 can be arranged at a position relatively stationary with respect to the torn workpiece. After starting tearing, the position of the material to be torn on the torn workpiece will change constantly, so the position of the material tearing mechanism 1 with respect to the torn workpiece can also be adjusted. The use of the positioning wheels 6 can enable the material tearing mechanism 1 to move automatically under the traction of the winding mechanism, so that the material tearing mechanism 1 is closer to the position where the current material to be torn is separated from the torn workpiece.

[0051] On the basis of the above-mentioned embodiments, the guide wheel 8 is partially located outside the housing, and the other part of the guide wheel 8 is located inside the housing.

[0052] The above arrangement helps to expose the guide position and helps the staff to intuitively understand the guide position. Of course, the guide wheel 8 can also be completely located outside the housing,

[0053] The speed control of the motor can be realized by the motor alone or by a controller connected to the motor. On the basis of any one of the above-mentioned embodiments, the motor 7 is connected to a controller, and the controller is provided with an input device for inputting the control speed of the motor 7.

[0054] The controller can be a chip, a single-chip microcomputer, or a computer having a control function, and the input device can be a keyboard.

[0055] On the basis of any one of the above-mentioned embodiments, a central positioning column 4 arranged on the fixed base is further included, and the housing is connected to the central positioning column 4 through a cantilever mechanism 5 which is rotatable with respect to the central positioning column 4.

[0056] The positioning column is a fixed structure which can be connected to a fixed position in space through the base.

[0057] The cantilever mechanism 5 is rotationally connected to the center positioning column 4, that is, can rotate around the center positioning column 4 and drive the shell connected thereto to rotate, so that the whole material tearing mechanism 1 can rotate around the center positioning column 4. In use, the center positioning column 4 is fixed relative to the workpiece to be torn and has a certain distance, the positioning mechanism of the material tearing mechanism 1 is connected to the workpiece to be torn, and when the rolling mechanism starts to tear the rubber, the material tearing mechanism 1 will move relative to the workpiece to be torn due to the traction of the rolling mechanism. The movement process is specifically rotation around the center positioning column 4. It can be seen that the above-mentioned surface-pasted material automatic tearing device is suitable for the scenario that the workpiece to be torn is in a ring structure. The center positioning column 4 can be arranged at the center axis position of the ring structure of the workpiece to be torn. By utilizing the characteristic that the material tearing mechanism 1 can rotate around the center positioning column 4 during the tearing process, the material tearing mechanism 1 rotates around the center positioning column 4 while moving on the surface of the workpiece to be torn, and will not be separated from the surface of the workpiece to be torn.

[0058] In order to adapt to workpieces to be torn with different diameters, on the basis of any one of the above-mentioned embodiments, the cantilever mechanism 5 includes at least three cantilever arms that are sequentially hingedly connected. The hinging shafts of adjacent cantilever arms are parallel to the axis of the center positioning column 4, so as to adjust the length of the cantilever mechanism 5.

[0059] The cantilever mechanism 5 is a telescopic rod group structure. By the relative rotation of the hingedly connected cantilever arms, the overall length of the cantilever mechanism 5 can be adjusted. It should be noted that the relative rotation of the cantilever arms can also realize relative fixation, so as to stabilize the length in the diameter.

[0060] In any one of the above-mentioned embodiments, in order to strengthen the stability between the cantilever arms and the shell and the center positioning column 4 and avoid the situation that deviation and jamming occur due to gravity, the shell and the cantilever arms located at the outer periphery and connected thereto are connected by a first connecting rod 2. The two ends of the first connecting rod 2 are connected to the shell and the cantilever arm, respectively. The shell, the cantilever arm and the first connecting rod 2 form a triangular fixed relationship.

[0061] The cantilever arm located at the center and connected to the center positioning column 4 is provided with a second connecting rod 3. The two ends of the second connecting rod 3 are connected to the center positioning column 4 and the cantilever arm, respectively. The center positioning column 4, the cantilever arm and the second connecting rod 3 form a triangular fixed relationship.

[0062] It can be known that the first connecting rod 2 is a rib plate member for strengthening the connection stability between the shell and the cantilever arm, which is used to avoid deflection. The second connecting rod 3 is a rib plate member for strengthening the connection stability between the cantilever arm and the center positioning column 4, which is used to avoid deflection.

[0063] Optionally, in order to ensure the stability and smoothness of the rotating process, the second connecting rod 3 is connected to the rotating ring of the center positioning column 4, or the second connecting rod 3 is connected to the bearing of the center positioning column 4.

[0064] It can be known that the rotating ring and the bearing can ensure the stability of the rotating direction and avoid the situation that cannot rotate due to gravity deviation.

[0065] Optionally, the material tearing mechanism 1 has at least two positioning mechanisms, and the positioning surface formed by the cantilever mechanism 5 and the positioning mechanism is vertically arranged.

[0066] The positioning wheel 6 provided in the application is preferably made of non-rigid material, which is attached to the adhesive surface of the material to be torn, thereby playing a positioning role on the workpiece to be torn; the surface adhesive material (i.e. the material to be torn) of the workpiece to be torn is introduced into the meshing position in the middle of the gear mechanism 9 inside the housing through the guiding action of the guide wheel 8, and is fixed, and a plurality of groups of gear mechanisms are driven to rotate by the motor 7, thereby continuously moving the surface adhesive material to the inside of the housing to realize tearing. The entire material tearing mechanism plays the functions of positioning, connection, rotation and tearing.

[0067] As a preferred scheme of the automatic tearing device for the surface adhesive material provided in the application: in the application, the first connecting rod 2 and the second connecting rod 3 are connecting members for connection, which can play a reinforcing function and prevent the cantilever mechanism 5 from deviating due to the bearing problem.

[0068] The cantilever mechanism 5 can be used as a structure for connecting the material tearing mechanism 1 and the center positioning column 4, and realizes the rotation of the material tearing mechanism 1, and the multiple-section cantilever arms are connected in a rotatable and telescopic manner, thereby adjusting the length to meet the workpieces of different diameters, and playing the functions of connection and length adjustment.

[0069] The scheme provided in the application connects the material to be torn of the workpiece to be torn by the material tearing mechanism 1, and the material can be torn in whole when rotating along the inner wall of the annular or arc-shaped workpiece, and the relative movement of the multiple groups of gears inside the material tearing mechanism 1 and the multiple-section telescopic cantilever arms realizes the tearing function of various types of surface materials, and the product has strong versatility, which can realize the purposes of reducing cost and labor intensity.

[0070] In use, first, the surface pasting material automatic tearing device is placed in a suitable station and fixed through the center positioning column 4; then, the workpiece to be torn is placed in the station, ensuring that the center positioning column 4 of the tearing device is at the center position of the workpiece to be torn; then, the cantilever mechanism 5 is adjusted to a suitable position according to the size of the workpiece, ensuring that the material tearing mechanism 1 is placed into the contact with the material pasting surface of the positioning wheel 6; after the material to be torn on the surface of the workpiece is opened by hand, the gear mechanism is fixed by being guided into a suitable position; then, the motor 7 drives the gear mechanism 9 to rotate, and the surface material is stretched outward, so that the whole material tearing mechanism 1 walks along the wall surface of the workpiece, and the surface pasting material of the workpiece is torn.

[0071] The scheme of the present application realizes the use of the telescopic cantilever mechanism 5 to meet the operation of workpieces of different diameters, and the gear mechanism 9 in the material tearing mechanism 1 meets the surface material tearing function of various widths without switching devices, which is strong in versatility and can reduce labor intensity.

[0072] In addition to the main structure and connection relationship of the surface pasting material automatic tearing device provided in each of the above embodiments, the structure of other parts of the surface pasting material automatic tearing device can refer to the prior art, and will not be described here.

[0073] Each of the embodiments in the specification is described in a progressive manner, and each embodiment focuses on the difference from other embodiments. The same and similar parts between each embodiment can be referred to.
