Description

Technical Field

[0001] This utility model belongs to the field of dredging tool technology, specifically relating to a quick dredging device for the forming cavity of a press bar machine. Background Technology

[0002] In the cigarette manufacturing workshop, the briquetting machine, through the action of the extrusion screw, extrusion forming cavity (or forming cavity), and heater, compresses the tobacco dust generated during the cigarette manufacturing and packaging process into cigarette briquettes for subsequent recycling.

[0003] However, after the briquette press finishes production, some tobacco residue remains in the extrusion molding cavity. Under the action of the extrusion screw, the tobacco residue becomes denser. After production ends, the extrusion screw stops running, and the briquettes are no longer output, leaving some briquettes stuck in the cavity. After the machine stops, the cavity still has residual heat and a high temperature. The tobacco oil produced during the extrusion process in the cavity before the machine stops gradually solidifies under the continuous baking of the residual heat in the extrusion molding cavity. After a long period of cooling, the briquettes stick to the inner wall of the cavity, causing blockage of the extrusion molding cavity. This prevents the briquette press from pressing briquettes normally, and the maintenance process is time-consuming and labor-intensive, so improvements are necessary. Utility Model Content

[0004] The purpose of this utility model is to provide a quick unblocking device for the forming cavity of a briquetting machine, so as to solve the problem of long maintenance time and high maintenance intensity caused by blockage in the forming cavity of the existing briquetting machine.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A quick unblocking device for the forming cavity of a bar press is provided for unblocking the forming cavity. It includes a chuck and a clamp. At least three non-collinear mounting holes are provided on the top surface of one side of the chuck. The mounting holes are used to install a connecting block. The connecting block is provided with a fixing hole for connecting with the clamp. A fastening structure is provided between the connecting block and the clamp. After the clamp locks the forming cavity, the fastening structure makes the contact surface between the clamp and the forming cavity fit tightly.

[0007] This application uses a fastening structure and clamps to clamp the forming cavity onto the worktable of a drilling machine. The drill bit of the drilling machine is used to clean the blockage of the smoke rod or smoke dust clumps in the forming cavity. The cleaned forming cavity can be reused. In addition, the mechanical energy of the drilling machine is used in the cleaning process, which effectively shortens the maintenance time and reduces the labor intensity of maintenance personnel. It is highly practical.

[0008] Further defining the fastening structure, the fastening structure includes connecting bolts and a contact wall, the contact wall being disposed on the side of the connecting block near the clamp and fitting against the outer wall of the forming cavity; the clamp is connected and fixed to both ends of the connecting block by connecting bolts and connecting nuts passing through the fixing holes.

[0009] Further specifying, the contact wall is configured as a long pad, with both ends of the long pad fitted onto the connecting bolt; or, the contact wall is configured as a movable pad, with the movable pad embedded in the limiting opening of the connecting block.

[0010] Among them, the assembly difficulty of using long pads is relatively simple. It is necessary to have holes in the connecting block so that it can be directly fitted onto the connecting bolts. Furthermore, after being used with the clamp, it can form a relatively complete circular fastening surface that contacts the forming cavity, making the clamping of the forming cavity more stable. When using movable pads, they can also be used with clamps to securely clamp the forming cavity. Movable pads can be easily replaced to provide contact surfaces with different friction coefficients and to adapt to forming cavities with different inner diameters.

[0011] Further specified, the side of the long pad or the movable pad closest to the forming cavity is configured as an arc-shaped contact surface.

[0012] Further specified, the connecting bolt is fitted with an elastic element, which is located between the connecting block and the clamp; wherein, the elastic element can improve the stability and reliability of the clamp during tightening, making the locking process smoother, and the elastic element can be a spring washer or a fastening spring.

[0013] Further, it also includes a multi-directional fine-tuning structure, which is fixedly connected to the bottom of the chuck and provides the chuck with compression stroke in at least two directions.

[0014] Further specified, the chuck is a circular chuck, one side of which has a notch for mounting the connecting block; the multi-directional fine-tuning structure includes a connecting seat and a limiting seat, the connecting seat being fixedly connected to the bottom of the circular chuck; a polygonal limiting ear plate is provided at the bottom end of the connecting seat, a limiting cavity is provided on the limiting seat, the polygonal limiting ear plate is disposed in the limiting cavity, and there is a gap between the polygonal limiting ear plate and the limiting cavity, the gap being provided with an elastic filler layer; the polygonal limiting ear plate is an equal hexagonal plate structure.

[0015] The multi-directional fine-tuning structure design can protect the forming cavity when cleaning it with a drill bit, avoiding or reducing the probability of the drill bit colliding with the inner wall of the forming cavity.

[0016] The utility model adopting the above technical solution has the following advantages:

[0017] In this application, a device consisting of a chuck and a clamp is used to clamp the forming cavity that needs to be cleaned. The forming cavity can be clamped onto the worktable of the drilling machine, and then the drill bit is used to clean the blocked smoke rod. Compared with manual cleaning, it can save maintenance time, reduce maintenance difficulty and labor intensity, and the formed cavity after maintenance can be reused, saving production costs. In addition, the overall structure of the device is relatively simple, the installation cost is low, and the practicality is high. Attached Figure Description

[0030] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. Furthermore, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0031] In this embodiment of the invention, the briquette press is a device that compresses tobacco dust generated during the tobacco processing and packaging processes into briquettes for subsequent recycling. Improving the production efficiency of the briquette press indirectly improves the efficiency of the tobacco processing workshop. The quality of the briquette press directly affects the waste disposal in both production workshops of the tobacco factory, thus indirectly impacting the factory's production efficiency. However, the forming cavity of the briquette press is prone to severe blockage, significantly affecting the factory's production efficiency and hindering cost reduction. Therefore, this embodiment of the invention provides a quick unblocking device for the forming cavity of the briquette press.

[0032] like Figure 1 , Figure 2 As shown in the figure, a quick unblocking device for the forming cavity of a press bar machine according to an embodiment of the present invention is used for unblocking the forming cavity 103. It includes a chuck 101 and a clamp 102. The chuck 101 can be made of a square alloy plate. Three non-collinear mounting holes 120 are provided on the top surface of one side of the chuck 101 for mounting connecting blocks 105. The connecting blocks 105 are L-shaped and have connecting holes 119 opposite to the mounting holes 120. They also have fixing holes 118 for connecting to the clamp 102. (See reference...) Figure 9A fastening structure is provided between the connecting block 105 and the clamp 102. After the clamp 102 locks the forming cavity 103, the fastening structure ensures that the contact surfaces between the clamp 102 and the forming cavity 103 are tightly fitted. After the clamp 102 clamps the forming cavity 103, the smoke sticks blocking the forming cavity 103 can be cleaned by a drilling machine. If the drilling machine cannot completely clean the smoke sticks blocking the forming cavity 103, a second cleaning can be performed manually after the initial cleaning to achieve a complete cleaning effect. Compared with manual cleaning or maintenance alone, this embodiment uses the drill bit of a drilling machine to clean the smoke sticks blocking the forming cavity 103. The cleaned forming cavity 103 can be reused. The mechanical energy of the drilling machine can be used during the cleaning process to reduce the labor intensity of maintenance personnel and effectively shorten the cleaning time. The device composed of the clamp 102 and the chuck 101 is highly practical.

[0033] In this embodiment, four or five non-collinear mounting holes 120 can be provided on one side of the top surface of the chuck 101 as needed, and the connecting block 105 can be installed by fixing screws 108. An external hole is machined on the other side of the chuck 101, and a T-block can be installed at the bottom of the external hole by mounting bolts. The T-block is slidably installed on the worktable of the drilling machine; a T-slot is provided on the worktable to engage with the T-block; after tightening the mounting bolts, the chuck 101 can be fixed relative to the worktable.

[0034] like Figures 3 to 5 As shown, in this embodiment, the fastening structure includes connecting bolts 104 and contact walls. The contact walls are located on the side of the connecting block 105 near the clamp 102 and fit against the outer wall of the forming cavity 103. The clamp 102 and the two ends of the connecting block 105 are connected and fixed by connecting bolts 104 and connecting nuts 110 passing through the fixing holes 118. It can be understood that the clamp 102 has extension ears opposite to the connecting block 105 at both ends and through holes are machined. The through holes allow the connecting bolts 104 to pass through.

[0035] In fact, rubber blocks can be provided on the inner wall of the contact wall and the clamp 102 to increase the friction on the forming cavity 103 and improve the fastening effect.

[0036] like Figure 2 , Figure 3 As shown, in this embodiment, the contact wall is configured as a long pad 106, with both ends of the long pad 106 fitted onto the connecting bolt 104. In practice, other contact walls can also be selected in this embodiment as needed; for example, the contact wall can be configured as a movable pad 109, which is embedded in the limiting opening 117 of the connecting block 105. (See also...) Figure 9This structural design simplifies assembly using the long pad 106, requiring only a hole in the connecting block 105 for direct mounting onto the connecting bolt 104. Furthermore, when combined with the clamp 102, it forms a relatively complete circular fastening surface that contacts the forming cavity 103, resulting in a more secure clamping of the forming cavity 103. The movable pad 109 can also be used in conjunction with the clamp 102 to securely clamp the forming cavity 103. The movable pad 109 is easily replaceable to provide contact surfaces with different friction coefficients and to accommodate forming cavities 103 with different inner diameters. Additionally, the fastening structure can be configured as follows: a hinge connecting one end of the connecting block 105 to the clamp 102, and a threaded connection at the other end using the connecting bolt 104; this prevents the clamp 102 from being lost after separation.

[0037] like Figures 2 to 4 As shown, in this embodiment, the side of the long pad 106 and the movable pad 109 near the forming cavity 103 can be set as an arc-shaped contact surface; the arc-shaped contact surface can fully fit tightly with the forming cavity 103, improve the friction performance at the contact position and thus improve the fastening performance.

[0038] like Figure 4 , Figure 5 As shown, in this embodiment, an elastic element is sleeved on the connecting bolt 104. The elastic element is located between the connecting block 105 and the clamp 102. The elastic element can be a spring washer 107. During assembly, on the one hand, the holes at both ends of the long pad 106 can be enlarged; on the other hand, when the movable pad 109 is used, it is not necessary to enlarge the holes. After the clamp 102 and the connecting block 105 are fixedly connected by the connecting bolt 104 and the connecting nut 110, the spring washer 107 can improve the stability and reliability of the clamp 102 when it is tightened, making the locking process smoother.

[0039] In fact, the elastic element in this embodiment can also be a fastening spring 111 or other elastic structures, depending on the time required.

[0040] In one embodiment, such as Figures 6-9 As shown, the device in this embodiment also includes a multi-directional fine-tuning structure, which is fixedly connected to the bottom of the chuck 101. The multi-directional fine-tuning structure provides the chuck 101 with compression strokes in two directions.

[0041] In this embodiment, the chuck 101 is configured as a circular chuck 112, with a notch on one side and a mounting hole 120 at the notch for mounting an L-shaped connecting block 105. The multi-directional fine-tuning structure includes a connecting seat 114 and a limiting seat 113. The connecting seat 114 is fixedly connected to the bottom of the circular chuck 112. A polygonal limiting ear plate is provided at the bottom end of the connecting seat 114. A limiting cavity 115 is provided on the limiting seat 113. The polygonal limiting ear plate is disposed in the limiting cavity 115, and there is a gap between the polygonal limiting ear plate and the limiting cavity 115. Solidified silicone is disposed in the gap as an elastic filler layer.

[0042] In practice, rubber rings or elastic balls can be added to the gaps; alternatively, the polygonal limiting ear plate can be set as an equal hexagonal plate structure. The compression stroke in this embodiment represents the deformation of the rubber ring or elastic ball when it is squeezed, and the amount of displacement due to the deformation corresponds to the amount of movement of the polygonal limiting ear plate, connecting seat 114, and circular chuck 112.

[0043] The multi-directional fine-tuning structure design in the above embodiments can provide a compressible stroke for the circular chuck 112 through the polygonal limiting ear plate and the limiting cavity 115 when cleaning the forming cavity 103 with the drill bit. This stroke has a certain elasticity and can cooperate with the radial displacement of the forming cavity 103 to protect the forming cavity 103; and avoid or reduce the probability of the drill bit colliding with the inner wall of the forming cavity 103.

[0044] like Figures 7 to 9 As shown, in this embodiment, the limiting seat 113 is formed by merging two semi-circular connecting sub-seats. An insertion port 116 is provided on the bottom wall of the connecting sub-seat. After the polygonal limiting ear plate is installed in the limiting cavity 115, the connecting sub-seat can be connected and fixed by the wedge block 121 inserted into the insertion port 116, thus forming the limiting seat 113. Correspondingly, the addition of a rubber ring or elastic ball can be made after the limiting seat 113 is formed. Furthermore, after fixing the connecting sub-seat, it can be fixed to the worktable of the drilling machine to complete the assembly of the device.

[0045] like Figure 8 As shown, the limiting seat 113 has a limiting cavity 115 that restricts the polygonal limiting ear plate in the vertical direction and leaves a gap in the horizontal direction. When the polygonal limiting ear plate is a hexagonal plate structure, the limiting cavity 115 is also a hexagonal concave cavity, providing reciprocating stroke in three directions for the polygonal limiting ear plate.

[0046] This structural design uses a device consisting of a chuck 101 and a clamp 102 to clamp the forming cavity 103 that needs to be cleaned. The forming cavity 103 can be clamped onto the worktable of the drilling machine, and then the drill bit can be used to clean the blocked smoke rod. Compared with manual cleaning, it can save maintenance time, reduce maintenance difficulty and labor intensity, and the formed cavity 103 can be reused after maintenance, saving production costs. Moreover, the overall structure is simple, low in cost and highly practical.

[0047] The above provides a detailed description of a quick unblocking device for the forming cavity of a bar press provided by this utility model. The specific embodiments are described only to help understand the method and core idea of ​​this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
