Description

Technical Field

[0001] The invention relates to the technical field of glass processing, and in particular to a float glass cutting device. Background Art

[0002] When using a common float glass cutting device, a cylinder and a rubber wheel are usually used to squeeze the top to fix the float glass. However, since the surface of the float glass is relatively smooth and the contact area between the float glass and the rubber wheel is small, the float glass may slip during the processing, causing the cutting position to shift, affecting the quality of the finished float glass product.

[0003] A float glass cutting device is disclosed in the prior art, comprising a workbench, a positioning groove is provided at the center of the top of the workbench, a notch is provided at the bottom of the positioning groove, a connecting pipe is slidably installed in the notch, and a positioning block is fixedly connected to the top of the connecting pipe. The bottom of the positioning block is fixedly connected to multiple groups of third springs, the bottom of the third spring is fixedly connected to the top of the positioning groove, the top of the positioning block is provided with sealing holes on both sides of the negative pressure hole, the bottom of the positioning block is fixedly connected to two groups of first springs, the bottoms of the two groups of the first springs are fixedly connected to a mounting plate, the top of the mounting plate is fixedly connected to a sealing block, the sealing block is located inside the first spring, and the two groups of the sealing blocks are respectively located at the bottoms of the two groups of sealing holes.

[0004] During use, before the third spring drives the positioning block to move upward under the action of its own elastic restoring force, the first spring is in a compressed state. When the third spring starts to push the positioning block upward, the sealing block is separated from the sealing hole under the action of the first spring's own elastic restoring force, so that the suction force of the negative pressure hole on the float glass is reduced. This greatly increases the risk of the float glass sliding on the positioning block when the third spring pushes the positioning block upward. Summary of the invention

[0005] The object of the present invention is to provide a float glass cutting device, in which the first spring is in a compressed state during the movement of the positioning block from the first preset position to the second preset position. At this time, under the action of the elastic restoring force of the first spring itself, the mounting plate continuously abuts against the lower end surface of the positioning block, and the sealing block continuously and tightly connected in the sealing hole. This ensures that the adsorption force of the negative pressure hole on the float glass will not be weakened during the movement of the positioning block from the first preset position to the second preset position, thereby achieving the purpose of reducing the risk of the sealing block escaping from the sealing hole prematurely, improving the stability of the float glass on the positioning block, and reducing the risk of the float glass sliding on the positioning block.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A float glass cutting device comprises a workbench and a first spring, the workbench table top is provided with a positioning groove, the bottom of the positioning groove is provided with a notch and a circular groove, a connecting pipe is slidably installed in the notch, the upper end of the connecting pipe is connected with a positioning block, the upper end surface of the positioning block is provided with a negative pressure hole and a sealing hole, the negative pressure hole is used to connect an air pump, a mounting plate is provided between the positioning block and the bottom of the positioning groove, the mounting plate corresponds to the circular groove, a sealing block is provided on the upper end surface of the mounting plate, the sealing block corresponds to the sealing hole, a third spring is connected to the lower end surface of the positioning block, one end of the third spring away from the positioning block is connected to the bottom of the positioning groove: both ends of the first spring The ends are respectively connected to the mounting plate and the bottom of the positioning groove; when the positioning block moves from the first preset position to the second preset position in a bottom-up direction under the elastic restoring force of the third spring itself, the first spring is in a compressed state, the mounting plate abuts against the positioning block, and the sealing block is connected to the sealing hole; when the positioning block moves to the second preset position, the first spring is in an initial state; when the positioning block moves from the second preset position to the third preset position in a bottom-up direction under the elastic restoring force of the third spring itself, the mounting plate gradually moves away from the positioning block under the elastic restoring force of the first spring itself, and the sealing block is separated from the sealing hole.

[0008] A further solution is that one end of the first spring away from the positioning block is connected to the bottom of the circular groove.

[0009] A further solution is: a first positioning hole is formed at the bottom of the circular groove; a first positioning column is provided on the lower end surface of the mounting plate; and the first positioning column penetrates the first spring and the first positioning hole.

[0010] A further solution is that when float glass is placed on the positioning block, the sum of the length of the third spring and the height of the circular groove wall is greater than the length of the first spring.

[0011] A further solution is that when the first spring is in a compressed state, a first force applied by the first spring to the mounting plate is greater than or equal to a second force applied by the third spring to the positioning block.

[0012] A further solution is: a second positioning hole is formed at the bottom of the positioning groove; a second positioning column is provided on the lower end surface of the positioning block; and the second positioning column is inserted into the second positioning hole.

[0013] A further solution is that the second positioning column is inserted into the third spring.

[0014] A further solution is that the distance between the first preset position and the second preset position is greater than the distance between the second preset position and the third preset position.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] On the one hand, during the movement of the positioning block from the first preset position to the second preset position, the first spring is in a compressed state. At this time, under the action of the elastic restoring force of the first spring itself, the mounting plate continuously abuts against the lower end surface of the positioning block, and the sealing block continuously and tightly connected in the sealing hole. This ensures that during the movement of the positioning block from the first preset position to the second preset position, the adsorption force of the negative pressure hole on the float glass will not be weakened, thereby achieving the purpose of reducing the risk of the sealing block escaping from the sealing hole prematurely, improving the stability of the float glass on the positioning block, and reducing the risk of the float glass sliding on the positioning block.

[0017] On the other hand, when the positioning block continues to move upward from the second preset position to the third preset position under the action of the elastic restoring force of the third spring, the mounting plate gradually moves away from the positioning block on the first spring, and the sealing block finally detaches from the sealing hole, thereby reducing the adsorption force of the negative pressure hole on the float glass, so that the staff can easily remove the float glass after cutting, thereby improving the work efficiency.

DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the accompanying drawings.

[0025] Example 1

[0026] The existing patent application document with application number 202311116169.9 discloses a float glass cutting device, comprising a workbench 1, a positioning groove 3 is provided at the center of the top of the workbench 1, a notch 4 is provided at the bottom of the positioning groove 3, a connecting pipe 6 is slidably installed in the notch 4, a positioning block 7 is fixedly connected to the top of the connecting pipe 6, a plurality of installation grooves are provided around the positioning groove 3 at the top of the workbench 1, a rotating shaft is rotatably connected to the side away from the positioning groove 3 in each of the installation grooves, an L-shaped fixing hook is fixedly connected to the outer wall of the rotating shaft, a rubber is provided on the L-shaped fixing hook away from the rotating shaft, a driving device is provided in each of the installation grooves, the driving device is used to drive the L-shaped fixing hook to fix the float glass, a negative pressure hole 8 is provided at the center of the top of the positioning block 7, a fixing assembly is provided on the outer wall of the positioning block 7, and the fixing assembly is used to fix the position of the positioning block 7. A plurality of third springs 12 are fixedly connected to the bottom of the positioning block 7, and the bottom of the third spring 12 is fixedly connected to the top of the positioning groove 3. The top of the positioning block 7 is provided with sealing holes 9 on both sides of the negative pressure hole 8, the bottom of the positioning block 7 is fixedly connected with two groups of first springs 2, the bottom of the two groups of first springs 2 are fixedly connected with a mounting plate 10, the top of the mounting plate 10 is fixedly connected with a sealing block 11, the sealing block 11 is located inside the first spring 2, the two groups of sealing blocks 11 are respectively located at the bottom of the two groups of sealing holes 9, the bottom of the positioning groove 3 is provided with two groups of circular grooves 5, the two groups of circular grooves 5 are respectively located at the bottom of the two groups of mounting plates 10. The fixing assembly includes a plurality of groups of second limiting grooves provided on the outer wall of the positioning block 7, each of which is fixedly connected with a second spring, each of which is fixedly connected with a second limiting block at one end away from the inner wall of the second limiting groove, and each of which is arc-shaped at one side away from the second spring, and the inner wall of the positioning groove 3 is provided with a plurality of groups of fixing grooves, the fixing grooves correspond to the second limiting blocks one by one.

[0027] During operation, in the initial state, the sealing block 11 is in a separated state from the sealing hole 9, and the first spring 2 is in a stress-free state. At this time, there is no sealed space between the positioning block 7 and the float glass. When performing the cutting work, the staff first places the float glass on the top of the positioning block 7, and under the action of the gravity of the float glass itself, the outer wall of its bottom will fit tightly with the positioning block 7, and then press the float glass downward, and drive the positioning block 7 at its bottom to enter the positioning groove 3. The bottom of the positioning block 7 will first contact the inclined surface of the push rod. As the positioning block 7 continues to be pressed downward, the push rod is squeezed to the side away from the positioning groove 3. When the push rod moves, the squeezing block will move to the side of the L-shaped fixing hook and squeeze it. The L-shaped fixing hook rotates under the squeezing of the squeezing block. The L-shaped fixing hook is in a tightened state and the torsion spring is compressed. At this time, the L-shaped fixing hook will apply a downward pressure to the float glass, thereby fixing the top of the float glass to prevent the float glass from sliding during processing, thereby ensuring that the cutting position will not be offset and the cutting operation is carried out normally. As the positioning block 7 continues to move, the first spring 2 is gradually compressed, the distance between the positioning block 7 and the mounting plate 10 is gradually reduced, and the sealing block 11 on the top of the mounting plate 10 enters the sealing hole 9, thereby sealing the sealing hole 9, forming a sealed space between the float glass and the rubber suction cup, and the exhaust pipe can extract the gas between the float glass and the rubber suction cup to ensure that the float glass has a good fixing effect.

[0028] When a cutting operation is completed, the staff will bend the two sets of L-shaped fixing hooks relative to each other outward, so that the L-shaped fixing hooks push the extrusion block and the push rod to one side of the positioning groove 3, and the push rod will enter the positioning groove 3 and squeeze the positioning block 7 upward. When the positioning block 7 moves upward, the inner wall of the fixing groove will squeeze the second limit block into the second limit groove again, releasing the fixation of the positioning block 7. Moreover, since the positioning block 7 will squeeze the third spring 12 when entering the positioning groove 3, when the fixation of the positioning block 7 is released, the positioning block 7 will be driven to move upward under the action of the elastic restoring force of the third spring 12 itself. At this time, the positioning block 7 no longer applies pressure to the push rod. The torsion spring's own elastic restoring force drives the L-shaped fixing hook to reset, so that the L-shaped fixing hook rotates back to the open state, thereby facilitating the staff to take out the cut float glass. When the L-shaped fixing hook rotates and resets, it pushes the extrusion block and the push rod to one side of the positioning groove 3, so that it can be used later. At this time, the sealing block 11 is reset under the action of the first spring 2's own elastic restoring force and disengaged from the sealing hole 9, so that there is no longer a sealed space between the float glass and the rubber suction cup, reducing the suction force of the negative pressure hole 8 on the float glass, so that the staff can easily remove the cut float glass, thereby improving work efficiency.

[0029] However, during use, there is a certain distance between the position of the positioning block 7 when it just starts to move upward and the position of the positioning block 7 when the positioning block 7 moves upward to the maximum recovery state of the third spring 12. Before the positioning block 7 is driven to move upward by the elastic restoring force of the third spring 12 itself, the first spring 2 is in a compressed state. When the third spring 12 just starts to push the positioning block 7 upward, the first spring 2, under the action of its own elastic restoring force, immediately pushes the mounting plate 10 to move away from the positioning block 7, so that the sealing block 11 is separated from the sealing hole 9, thereby reducing the suction force of the negative pressure hole 8 on the float glass. As a result, the third spring 12, under the action of its own restoring force, pushes the positioning block 7 to move upward from the position when it starts to move upward to the position of the maximum recovery state of the third spring 12, and the suction force of the negative pressure hole 8 on the float glass is reduced, which greatly increases the risk of the float glass sliding on the positioning block 7.

[0030] Therefore, this embodiment provides a float glass cutting device, such as Figure 1-Figure 3 As shown, it includes a workbench 1 and a first spring 2, the table top of the workbench 1 is provided with a positioning groove 3, the bottom of the positioning groove 3 is provided with a notch 4 and a circular groove 5, a connecting pipe 6 is slidably installed in the notch 4, the upper end of the connecting pipe 6 is connected to a positioning block 7, the upper end surface of the positioning block 7 is provided with a negative pressure hole 8 and a sealing hole 9, the negative pressure hole 8 is used to connect an air pump, a mounting plate 10 is arranged between the positioning block 7 and the bottom of the positioning groove 3, the mounting plate 10 corresponds to the circular groove 5, a sealing block 11 is arranged on the upper end surface of the mounting plate 10, the sealing block 11 corresponds to the sealing hole 9, the lower end surface of the positioning block 7 is connected to a third spring 12, and the end of the third spring 12 away from the positioning block 7 is connected to the bottom of the positioning groove 3: the first spring 2 The two ends are respectively connected to the mounting plate 10 and the bottom of the positioning groove 3; when the positioning block 7 moves from the first preset position to the second preset position along the bottom-up direction under the elastic restoring force of the third spring 12 itself, the first spring 2 is in a compressed state, the mounting plate 10 abuts against the positioning block 7, and the sealing block 11 is connected to the sealing hole 9; when the positioning block 7 moves to the second preset position, the first spring 2 is in an initial state; when the positioning block 7 moves from the second preset position to the third preset position along the bottom-up direction under the elastic restoring force of the third spring 12 itself, the mounting plate 10 gradually moves away from the positioning block 7 under the elastic restoring force of the first spring 2 itself, and the sealing block 11 is separated from the sealing hole 9.

[0031] Exemplarily, during the implementation process, the first spring 2 is arranged between the positioning block 7 and the bottom of the positioning groove 3, and the two ends of the first spring 2 are respectively connected to the lower end surface of the mounting plate 10 and the bottom of the positioning groove 3 by welding, screwing, etc.

[0032] Between the position of the positioning block 7 when it just starts to move upward and the position of the positioning block 7 when the positioning block 7 moves upward to the maximum recovery state of the third spring 12, there are preset first preset positions, second preset positions and third preset positions. Among them, the first preset position, the second preset position and the third preset position are arranged in sequence from bottom to top. Among them, the first preset position is preferably the position of the positioning block 7 when it just starts to move upward, the third preset position is preferably the position of the positioning block 7 when the positioning block 7 moves upward to the maximum recovery state of the third spring 12, and the second preset position is between the first preset position and the third preset position.

[0033] During use, when the positioning block 7 is released from being fixed, the positioning block 7 will, under the action of the elastic restoring force of the third spring 12 itself, pass through the first preset position, the second preset position and the third preset position in sequence along the bottom-up direction. During the movement of the positioning block 7 from the first preset position to the second preset position, the first spring 2 is in a compressed state. At this time, under the action of the elastic restoring force of the first spring 2 itself, the mounting plate 10 continues to abut against the lower end surface of the positioning block 7, and the sealing block 11 continues to be tightly connected in the sealing hole 9. This ensures that during the movement of the positioning block 7 from the first preset position to the second preset position, the adsorption force of the negative pressure hole 8 on the float glass will not be weakened, thereby achieving the purpose of reducing the risk of the sealing block 11 escaping from the sealing hole 9 prematurely, improving the stability of the float glass on the positioning block 7, and reducing the risk of the float glass sliding on the positioning block 7.

[0034] like Figure 2 As shown, when the positioning block 7 reaches the second preset position, the first spring 2 returns to the initial state. At this time, the mounting plate 10 and the lower end surface of the positioning block 7 are no longer in contact with each other, but are only fitted together, and the sealing block 11 is tightly connected in the sealing hole 9.

[0035] When the positioning block 7 continues to move upward from the second preset position to the third preset position under the elastic restoring force of the third spring 12, the mounting plate 10 gradually moves away from the positioning block 7 on the first spring 2, and the sealing block 11 finally leaves the sealing hole 9. This reduces the adsorption force of the negative pressure hole 8 on the float glass, so that the staff can easily remove the float glass after cutting, thereby improving the work efficiency.

[0036] Example 2

[0037] In order to better accommodate the first spring 2 in the circular groove 5. Figure 1As shown, based on the above-mentioned embodiment 1, in this embodiment, one end of the first spring 2 away from the positioning block 7 is connected to the bottom of the circular groove 5 .

[0038] For example, in the implementation process, the end of the first spring 2 away from the positioning block 7 is connected to the bottom of the circular groove 5 by welding, screwing, etc. During use, when the L-shaped fixing hook applies a downward pressure to the float glass and fixes the top of the float glass, the first spring 2 is in a maximum compression state. At this time, the first spring 2 is hidden in the circular groove 5. Thus, the first spring 2 is better accommodated to reduce the probability of the first spring 2 being damaged by the friction of the positioning block 7.

[0039] Example 3

[0040] In order to reduce the risk of deflection or twisting of the first spring 2 when compressed or stretched. Figure 1 As shown, based on the above-mentioned embodiment 2, in this embodiment, a first positioning hole 13 is opened at the bottom of the circular groove 5; a first positioning column 14 is provided on the lower end surface of the mounting plate 10; and the first positioning column 14 is penetrated into the first spring 2 and the first positioning hole 13.

[0041] Exemplarily, in the implementation process, a first positioning hole 13 is opened at the bottom of the circular groove 5, and a first positioning column 14 is connected to the lower end surface of the mounting plate 10 by welding, screwing, etc. The diameter and length of the first positioning column 14 are matched with the first positioning hole 13, and the first positioning column 14 corresponds to the position of the first positioning hole 13, so that the first positioning column 14 can be inserted into the first positioning hole 13 and the first spring 2.

[0042] Preferably, the diameter of the first positioning column 14 is slightly smaller than the central hole diameter of the first spring 2, so that there is a sufficient contact area between the first positioning column 14 and the first spring 2 to provide a stable guiding effect.

[0043] During use, when the mounting plate 10 slides in the vertical direction, the first positioning column 14 can position the movement direction of the mounting plate 10, so as to ensure that the mounting plate 10 can be accurately received in the circular groove 5, and that the sealing block 11 on the mounting plate 10 can be accurately connected to the sealing hole 9. At the same time, during the compression and extension of the first spring 2, the first positioning column 14 can guide the first spring 2, so as to ensure that the first spring 2 moves in a straight line during operation, thereby reducing the risk of deflection or distortion of the first spring 2 during compression or extension.

[0044] Example 4

[0045] In order to achieve the purpose of timely separation of the mounting plate 10 and the positioning hole at the second preset position. Figure 3As shown, based on the above-mentioned embodiment 2, in this embodiment, when float glass is placed on the positioning block 7 , the sum of the length of the third spring 12 and the height of the wall of the circular groove 5 is greater than the length of the first spring 2 .

[0046] For example, during the implementation, when the float glass is placed on the positioning block 7, the third spring 12 is in a compressed state under the gravity of the float glass. At this time, the sum of the length of the third spring 12 and the height of the wall of the circular groove 5 is greater than the length of the first spring 2. In other words, there is a gap between the lower end surface of the positioning block 7 and the upper end surface of the mounting plate 10, so that the first spring 2 is in an initial state at this time. Thus, when the positioning block 7 moves from the second preset position to the third preset position, the mounting plate 10 is separated from the positioning block 7 in time, so as to timely reduce the adsorption force of the negative pressure hole 8 on the float glass.

[0047] Example 5

[0048] In order to achieve the purpose that the first spring 2 can continuously abut the mounting plate 10 against the lower end surface of the positioning block 7. Figure 1 As shown, based on the above-mentioned embodiment 4, in this embodiment, when the first spring 2 is in a compressed state, the first force applied by the first spring 2 to the mounting plate 10 is greater than or equal to the second force applied by the third spring 12 to the positioning block 7.

[0049] Exemplarily, during implementation, when the first spring 2 is in a compressed state, the third spring 12 is also in a compressed state. At this time, the first force applied by the first spring 2 on the mounting plate 10 is greater than or equal to the second force applied by the third spring 12 on the positioning block 7.

[0050] During use, when the positioning block 7 moves from the first preset position to the second preset position, the first spring 2 and the third spring 12 are both in a compressed state. At this time, because the first force applied by the first spring 2 on the mounting plate 10 is greater than or equal to the second force applied by the third spring 12 on the positioning block 7, the first spring 2 can continuously abut the mounting plate 10 against the lower end surface of the positioning block 7, thereby continuously and tightly connecting the sealing block 11 in the sealing hole 9. This ensures that the adsorption force of the negative pressure hole 8 on the float glass will not weaken, thereby improving the stability of the float glass on the positioning block 7 and reducing the risk of the float glass sliding on the positioning block 7.

[0051] Example 6

[0052] The connecting pipe 6 is slidably arranged in the slot 4. Therefore, in order to reduce the risk of the positioning block 7 rotating in the horizontal plane during the vertical movement of the positioning block 7. Figure 1 Combination Figure 4As shown, based on the above-mentioned embodiment 1, in this embodiment, a second positioning hole 15 is opened at the bottom of the positioning groove 3; a second positioning column 16 is provided on the lower end surface of the positioning block 7; and the second positioning column 16 is penetrated into the second positioning hole 15.

[0053] Exemplarily, in the implementation process, a second positioning hole 15 is opened at the bottom of the positioning groove 3, and a second positioning column 16 is connected to the lower end surface of the positioning block 7 by welding, screwing, etc. The diameter and length of the second positioning column 16 are matched with the second positioning hole 15, and the second positioning column 16 corresponds to the position of the second positioning hole 15, so that the second positioning column 16 can be inserted into the second positioning hole 15.

[0054] During use, when the positioning block 7 slides in the vertical direction, the second positioning column 16 can position the movement direction of the mounting plate 10, thereby reducing the risk of the positioning block 7 rotating in the horizontal plane and ensuring that the positioning hole can be accurately connected to the sealing block 11.

[0055] Example 7

[0056] In order to reduce the risk of the third spring 12 being deflected or twisted when compressed or stretched. Figure 1 As shown, on the basis of the above-mentioned embodiment 6, in this embodiment, the second positioning column 16 is penetrated in the third spring 12 .

[0057] For example, during implementation, the diameter of the second positioning column 16 is slightly smaller than the central hole diameter of the third spring 12, and the second positioning column 16 is inserted into the third spring 12, so that there is enough contact area between the second positioning column 16 and the third spring 12 to provide a stable guiding effect. During the compression and extension process of the third spring 12, the second positioning column 16 can guide the third spring 12 to ensure that the third spring 12 moves in a straight line during operation, thereby reducing the risk of deflection or distortion of the third spring 12 during compression or extension.

[0058] Example 8

[0059] In order to further reduce the risk of the float glass sliding on the positioning block 7. Based on the above embodiment 1, in this embodiment, the distance between the first preset position and the second preset position is greater than the distance between the second preset position and the third preset position.

[0060] Exemplarily, during implementation, the distance between the first preset position (the position where the positioning block 7 starts to rise) and the second preset position (the position where the first spring 2 recovers from the compressed state to the initial state) is greater than the distance between the second preset position and the third preset position (the final position reached by the positioning block 7). On the one hand, the longer distance between the first preset position and the second preset position. This ensures that in the initial stage of the rising of the positioning block 7, the sealing block 11 and the sealing hole 9 remain tightly connected, maintaining sufficient adsorption force, thereby reducing the risk of the float glass sliding on the positioning block 7. At the same time, the shorter distance between the second preset position and the third preset position. This shortens the distance that the positioning block 7 moves after the adsorption force is reduced, thereby reducing the risk of the float glass sliding on the positioning block 7.

More specifically, within the scope of the present disclosure, drawings, and claims, a variety of variations and improvements may be made to the components and / or layout of the subject combination layout.
