Description

Technical Field

[0001] The present invention relates to the technical field of abrasive roll processing equipment, and particularly relates to a pulling and clamping device for abrasive rolls. Background Art

[0002] The main function of abrasive rolls is to polish and grind various workpieces, and they are characterized by high efficiency, safety, and high precision. The process of abrasive rolls is to bond abrasives to raw materials such as cloth bases or paper bases, so they are also called coated abrasives or flexible abrasives. Due to the soft substrate, abrasive rolls are very safe during polishing and have low grinding costs.

[0003] During the processing of abrasive rolls, a pulling and clamping process before cutting the raw materials is required. However, the existing pulling and clamping process needs to be manually operated step by step. Such a design is time-consuming and laborious, and to a certain extent, it affects the processing efficiency of abrasive rolls, which is not conducive to popularization and use.

[0004] Therefore, how to provide a fully automatic pulling and clamping device for abrasive rolls has become a technical problem to be solved by those skilled in the art. Summary of the Invention

[0005] The technical problem to be solved by the present invention is how to provide a fully automatic pulling and clamping device for abrasive rolls.

[0006] To achieve the above object, the present invention provides a pulling and clamping device for abrasive rolls, including: a base, on one side above the base, there is a conveying platform for conveying abrasive roll raw materials, on the opposite side of the base above the conveying platform, there are a pulling part, a clamping part, a winding part, and a cutting part, and the conveying platform, the pulling part, the clamping part, the winding part, and the cutting part are electrically connected to an external control box to form a fully automatic function.

[0007] The design of the base plays a role in fixing and supporting the device. When the abrasive roll raw materials are conveyed to a specified position by the conveying platform, first, a specified length of the abrasive roll is pulled out by the pulling part, then fixed and clamped by the clamping part, then formed into an "X" - shaped cross by the winding part, and finally cut off by the cutting part. During use, the conveying platform, the pulling part, the clamping part, the winding part, and the cutting part are all automatically operated by the control box, reflecting the automation degree of the device.

[0008] Preferably, the base has a rectangular structure, and the rectangular base is made of stainless steel. There are pre - set fixing holes with internal threads on the rectangular base, and two groups of fixing holes are symmetrically arranged about the longitudinal central axis of the base.

[0009] The base with a rectangular structure has a large contact area with the external ground, thus ensuring the stability of the fixed support of the base for this device. The base made of stainless steel has good anti-corrosion and corrosion resistance properties, thus extending the service life of the base. The design of the internally threaded fixing holes facilitates the user to insert bolts into it, thus ensuring the stability of the connection between the base and the external ground.

[0010] Preferably, the conveying platform is arranged parallel to the base, with its head and tail ends forming an input end and an output end, and a limiting mechanism is arranged at the output end of the conveying platform. The limiting mechanism includes a limiting sleeve and a limiting roller; The limiting sleeve has a cylindrical structure and is arranged parallel to the output end of the conveying platform; The limiting roller is installed at one end of the limiting sleeve away from the conveying platform.

[0011] The design of the limiting mechanism functions to limit the sand roll raw materials conveyed by the conveying platform, enabling them to always be conveyed within this plane and avoiding the phenomenon of the sand roll raw materials shifting during conveyance. The design of the limiting sleeve and the limiting roller provides a dual limiting function for the conveyance of the sand roll raw materials, reflecting the practicality of this device.

[0012] Preferably, a movable bearing is arranged between the limiting roller and the limiting sleeve, forming a movable connection structure.

[0013] With this design, the gap between the upper and lower rollers of the limiting roller can be adjusted according to the thickness of the sand roll raw materials, so that this device is applicable to different models of sand roll raw materials, reflecting the practicality of this device.

[0014] Preferably, an adjustment structure is arranged between the conveying platform and the base. The adjustment structure includes a longitudinal sliding table and a transverse sliding table; The longitudinal sliding table is vertically arranged above the base, and a positioning plate is arranged on the front surface of the longitudinal sliding table. The front surface of the positioning plate is connected to the conveying platform, and a longitudinal drag chain is connected to one side of the longitudinal sliding table; The transverse sliding table is installed on the upper end surface of the base, and the upper end surface of the transverse sliding table is connected to the bottom of the longitudinal sliding table. A transverse drag chain is arranged on one side of the transverse sliding table.

[0015] Both the longitudinal sliding table and the transverse sliding table adopt existing structures in the market in this field, and are used to adjust the conveying platform to a specified position according to actual needs, so that the sand roll raw materials can perform corresponding processes. This method is common knowledge in this field, so it will not be elaborated here.

[0016] Preferably, the pulling part, the clamping part, the winding part and the cutting part are longitudinally arranged in sequence from top to bottom on one side of the conveying platform, and the pulling part, the clamping part, the winding part and the cutting part are installed above the base through a fixed seat.

[0017] The upper and lower parts are arranged in sequence, which not only facilitates the corresponding process of the sand roll raw materials, but also improves the overall aesthetics of the device. The design of the fixed seat plays a role in fixing and supporting the pulling part, the clamping part, the winding part and the cutting part.

[0018] Preferably, a movable bearing is provided between the clamping portion, the winding portion and the fixed seat to form a rotating structure.

[0019] With this design, the angles of the clamping portion and the winding portion can be adjusted according to actual needs, further demonstrating the practicality of the device.

[0020] Preferably, the fixing seat and the base are connected by welding or by bolts.

[0021] The connection method between the fixing seat and the base can be selected according to the needs of the user. If welding is used, the stability of the connection between the fixing seat and the base is guaranteed. If a bolt-type detachable design is used, while ensuring the stability of the connection between the fixing seat and the base, it is easy to disassemble and assemble, thereby facilitating mobile transportation and subsequent inspection and maintenance processes.

[0022] Preferably, a storage tube is further included, which is installed on the upper end surface of the base, and both upper and lower ends of the storage tube are open structures, and the upper end of the storage tube is circular, and the lower end is a "funnel" structure.

[0023] The storage tube is used to collect waste materials when cutting abrasive roll raw materials. The round upper end of the storage tube has a larger radius to prevent waste materials from falling onto the base. The "funnel"-shaped inner wall at the lower end of the storage tube is inclined and has a certain guiding function, thereby preventing waste materials from accumulating inside the storage tube.

[0024] Preferably, a discharge port is provided at the lower end of the storage tube, and the discharge port passes through a preset clearance hole on the base to the bottom of the base.

[0025] This design allows the discharge port to be connected to an external cleaning device, thereby centrally cleaning the waste.

[0026] The beneficial effects of the present invention are: 1. When the present invention is in use, when the abrasive roll material is transported to the designated position via the conveying platform, the abrasive roll of the designated length is firstly pulled out and away through the drawing part, then fixed and clamped by the clamping part, and then formed into an "X"-shaped cross through the winding part, and finally cut by the cutting part. When in use, the conveying platform, the drawing part, the clamping part, the winding part and the cutting part are all automatically operated by the control box, which reflects the degree of automation of the device and is conducive to its popularization and use.

[0027] 2. When the present invention is in use, the design of the limiting mechanism functions to limit the sand roll raw materials conveyed by the conveying platform, enabling them to always be conveyed within this plane and avoiding the phenomenon of the sand roll raw materials shifting during conveyance. The design of the limiting sleeve and the limiting roller provides a dual limiting function for the conveyance of the sand roll raw materials, demonstrating the practicality of this device.

[0028] 3. When the present invention is in use, the waste generated during the cutting of the sand roll raw materials is collected by the storage cylinder, and the waste is discharged into an external cleaning device through the discharge port. The waste is centrally cleaned by the cleaning device, demonstrating the environmental friendliness of this device and conforming to the existing environmental protection concept.
