Description

Technical Field

[0001] This utility model relates to the field of dispensing equipment technology, and in particular to a horizontally disassembled spray valve. Background Technology

[0002] Hot melt adhesive spraying valves, widely used in packaging, printing, and wood processing, primarily function to heat hot melt adhesive to a liquid state and spray it onto the target object through a nozzle. Existing hot melt adhesive spraying valves require disassembling the adhesive reservoir from bottom to top, leading to the following problems:

[0003] ① Inconvenient replacement of the glue storage cylinder: There are usually other components on the top of the glue storage cylinder. The structure design of disassembling from bottom to top means that when it is necessary to disassemble the glue storage cylinder, all the components on the top of the glue storage cylinder must be disassembled first. This is a lot of work, cumbersome, time-consuming and labor-intensive.

[0004] ② Adhesive leakage during disassembly of the glue storage cylinder: When disassembling the glue storage cylinder from bottom to top, residual adhesive inside the cylinder will drip downwards and remain on the components below the cylinder (usually the glue dispensing assembly), which is difficult to clean and affects the service life and hygiene of the equipment.

[0005] To address the aforementioned problems, this utility model aims to improve existing injection valves, thereby resolving the issues of inconvenient replacement of the glue reservoir and the tendency for glue to remain on components below the glue reservoir during replacement.

[0006] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0007] One objective of this invention is to provide a horizontally detachable spray valve that can effectively solve the problems of inconvenient replacement of the glue reservoir and glue residue on the components below the glue reservoir when replacing the glue reservoir.

[0008] To achieve the above objectives, this utility model provides a horizontally detachable injection valve, comprising:

[0009] A glue dispensing assembly for spraying glue outwards;

[0010] A glue tube side clamp assembly, located above the glue dispensing assembly, includes a fixed clamping part and a movable clamping part that is detachably installed on the side of the fixed clamping part and is used to cooperate with the fixed clamping part to clamp the glue tube laterally to the glue tube pressing assembly to tighten the glue storage tube.

[0011] A glue cylinder clamping assembly is located above the glue cylinder side clamping assembly and is used to press the glue storage cylinder downward.

[0012] Optionally, one side of the movable clamping part is hinged to one side of the fixed clamping part about a vertical axis.

[0013] The other side of the movable clamping part is fastened to the other side of the fixed clamping part by a detachable fastener.

[0014] Optionally, both the fixed clamping part and the movable clamping part include a clamping part body for laterally clamping the glue storage cylinder, and a glue cylinder electric heating component inserted into the clamping part body.

[0015] Optionally, the dispensing assembly includes:

[0016] A flow channel plate, the flow channel plate having an adhesive flow channel and an adhesive cylinder connector for connecting one end of the adhesive flow channel to the adhesive storage cylinder;

[0017] A glue dispensing nozzle is mounted on the flow channel plate, and the glue inlet of the glue dispensing nozzle is connected to the other end of the glue flow channel.

[0018] An air jet valve is connected to the air inlet of the dispensing nozzle.

[0019] Optionally, the flow channel plate is provided with a flow channel electric heating component.

[0020] Optionally, the rubber sleeve clamping assembly includes:

[0021] The spray valve bracket, the glue dispensing assembly and the glue cartridge side clamp assembly are both mounted on the spray valve bracket;

[0022] A rubber tube clamping block is located above the rubber tube side clamping assembly and is slidably disposed above and below the injection valve bracket;

[0023] A ring-shaped adjustment knob, the outer wall of which is rotatably connected to the injection valve bracket, and the rubber cylinder pressure block extends into the ring-shaped adjustment knob and is threadedly connected to the inner wall of the ring-shaped adjustment knob.

[0024] Optionally, the glue storage cylinder is provided with an upward-facing glue storage cavity;

[0025] The rubber cylinder pressing block is provided with an air inlet channel that connects to the top opening of the rubber storage chamber.

[0026] Optionally, the outer wall of the annular adjustment knob is provided with anti-slip protrusions.

[0027] Optionally, the bottom of the glue cylinder pressure block is provided with an annular sealing gasket for abutting against the glue storage cylinder.

[0028] The beneficial effects of this utility model are as follows: It provides a horizontally detachable injection valve, which is convenient when the glue reservoir needs to be replaced:

[0029] First, the glue cylinder clamping assembly is lifted and disengaged from the glue storage cylinder;

[0030] Then, the movable clamping part is disassembled laterally to release the glue reservoir from the fixed clamping part, thus achieving horizontal disassembly;

[0031] Next, the old glue storage cylinder can be removed horizontally and replaced with a new glue storage cylinder;

[0032] Subsequently, the glue cylinder clamping assembly is used to press the glue storage cylinder downwards;

[0033] Finally, the movable clamping part is repositioned to the side of the fixed clamping part, so that the movable clamping part cooperates with the fixed clamping part to clamp the new glue reservoir laterally.

[0034] Traditional injection valves require disassembling the glue reservoir from bottom to top, while the horizontal disassembly injection valve provided by this utility model adopts a side disassembly design:

[0035] On the one hand, this design avoids disassembling all the components above the glue storage cylinder, greatly reducing the workload and working time, making the operation of replacing the glue storage cylinder simpler, and greatly improving the efficiency of replacing the glue storage cylinder.

[0036] On the other hand, due to the horizontal disassembly method, the glue reservoir does not move up and down for extended periods during disassembly, thus reducing the possibility of glue dripping downwards. Even if a small amount of residual glue remains, it will not drip directly onto the dispensing assembly below due to the horizontal disassembly direction. This design effectively keeps the dispensing assembly clean, extends the equipment's lifespan, and improves the equipment's hygiene.

[0037] Therefore, the horizontally detachable spray valve provided by this utility model can effectively solve the problems of inconvenient replacement of the glue reservoir and glue residue on the components below the glue reservoir when replacing the glue reservoir. Attached Figure Description

[0055] This utility model provides a horizontally detachable spray valve, which is suitable for dispensing operations in packaging, printing, wood processing and other fields that require efficient and convenient replacement of the glue reservoir and require keeping the equipment clean. It can effectively solve the problems of inconvenient glue reservoir replacement and glue residue on the parts below the glue reservoir when replacing the glue reservoir, which are problems of existing spray valves.

[0056] See Figures 1-3 The horizontally detachable injection valve provided in this embodiment includes:

[0057] Glue dispensing assembly 1, which is used to spray glue outward;

[0058] The glue tube side clamping assembly 2 is located above the glue dispensing assembly 1 and includes a fixed clamping part 201a and a movable clamping part 201b that is detachably installed on the side of the fixed clamping part 201a and is used to cooperate with the fixed clamping part 201a to clamp the glue storage tube 100 laterally with the glue tube pressing assembly 3.

[0059] The glue cylinder clamping assembly 3 is located above the glue cylinder side clamping assembly 2 and is used to press the glue storage cylinder 100 downward.

[0060] The horizontally detachable injection valve provided in this embodiment is used when the glue reservoir 100 needs to be replaced:

[0061] First, the glue cylinder clamping assembly 3 is disengaged upward from the glue storage cylinder 100;

[0062] Then, the movable clamping part 201b is disassembled laterally, so that the glue storage cylinder 100 is released from the fixed clamping part 201a, thus achieving horizontal disassembly;

[0063] Next, the old glue storage cylinder 100 can be removed horizontally and replaced with a new glue storage cylinder 100.

[0064] Subsequently, the glue cylinder pressing assembly 3 presses the glue storage cylinder 100 downward;

[0065] Finally, the movable clamping part 201b is repositioned to the side of the fixed clamping part 201a, so that the movable clamping part 201b cooperates with the fixed clamping part 201a to clamp the new glue storage cylinder 100 laterally.

[0066] Traditional spray valves require disassembling the glue reservoir 100 from bottom to top, while the horizontal disassembly spray valve provided by this utility model adopts a side disassembly design:

[0067] On the one hand, this design avoids disassembling all the components above the glue storage cylinder 100, greatly reducing the workload and working time, making the operation of replacing the glue storage cylinder 100 simpler, and greatly improving the efficiency of replacing the glue storage cylinder 100.

[0068] On the other hand, due to the horizontal disassembly method, the glue storage cylinder 100 will not move up and down for an extended period during disassembly, thus reducing the possibility of glue dripping downwards. Even if a small amount of residual glue remains, it will not drip directly onto the glue dispensing assembly 1 below due to the horizontal disassembly direction. This design effectively keeps the glue dispensing assembly 1 clean, extends the service life of the equipment, and improves the hygiene of the equipment.

[0069] Therefore, the horizontally detachable spray valve provided by this utility model can effectively solve the problems of inconvenient replacement of the glue storage cylinder 100 and glue residue on the components below the glue storage cylinder 100 when replacing the glue storage cylinder 100.

[0070] In this embodiment, one side of the movable clamping part 201b is hinged to one side of the fixed clamping part 201a around a vertical axis, and the other side of the movable clamping part 201b is fastened to the other side of the fixed clamping part 201a by a detachable fastener 202. Loosening the fastener 202 allows the movable clamping part 201b to be opened, thereby allowing the glue storage cylinder 100 to be removed; tightening the fastener 202 allows the movable clamping part 201b to cooperate with the fixed clamping part 201a to laterally clamp the glue storage cylinder 100.

[0071] Optionally, both the fixed clamping part 201a and the movable clamping part 201b include a clamping part body 2011 for laterally clamping the glue storage cylinder 100, and a glue cylinder electric heating component 2012 inserted into the clamping part body 2011.

[0072] The electric heating element 2012 for the glue cylinder can be a heating rod or a heating wire. Supplying power to the electric heating element 2012 heats the clamping body 2011, thereby heating and melting the glue material inside the glue storage cylinder 100 from both sides. Heating the glue storage cylinder 100 from both sides simultaneously improves the uniformity and efficiency of heating.

[0073] In this embodiment, the glue dispensing assembly 1 includes a flow channel plate 101, a glue dispensing nozzle 102, and an air jet valve 103. The flow channel plate 101 is provided with a glue flow channel 1011 and a glue cylinder connector 1012 for connecting one end of the glue flow channel 1011 to the glue storage cylinder 100; the glue dispensing nozzle 102 is installed on the flow channel plate 101, and the glue inlet of the glue dispensing nozzle 102 is connected to the other end of the glue flow channel 1011; the air jet valve 103 is connected to the air inlet of the glue dispensing nozzle 102.

[0074] After the jet valve 103 jets air into the glue dispensing nozzle 102, the glue in the glue flow channel 1011 will be ejected outward through the glue dispensing nozzle 102 under the action of pressure difference. The method of jet-induced glue dispensing is prior art and is not the focus of this utility model, so it will not be described in detail.

[0075] Furthermore, the flow channel plate 101 is provided with a flow channel electric heating component for heating the adhesive material in the adhesive flow channel 1011.

[0076] Both the glue tube side clamp assembly 2 and the glue dispensing assembly 1 are equipped with electric heating components. This structural design allows the flow channel heating and glue tube heating to be controlled independently. When the glue storage cylinder 100 is replaced or an abnormality occurs, the glue dispensing assembly 1 or the glue tube side clamp assembly 2 can be disassembled separately without causing glue blockage due to complete loss of heating, which is conducive to quick repair and production recovery.

[0077] The glue cartridge clamping assembly 3 includes a spray valve bracket 301, a glue cartridge clamping block 302, and an annular adjustment knob 303. Both the glue dispensing assembly 1 and the glue cartridge side clamping assembly 2 are mounted on the spray valve bracket 301. The glue cartridge clamping block 302 is located above the glue cartridge side clamping assembly 2 and is slidably disposed vertically with the spray valve bracket 301. The outer wall of the annular adjustment knob 303 is rotatably connected to the spray valve bracket 301, and the glue cartridge clamping block 302 extends into the annular adjustment knob 303 and is threadedly connected to the inner wall of the annular adjustment knob 303.

[0078] Because the rubber sleeve pressure block 302 is both slidably connected to the injection valve bracket 301 and threadedly connected to the inner wall of the annular adjustment knob 303:

[0079] When the ring-shaped adjustment knob 303 is turned in the forward direction, the glue cylinder pressure block 302 will slide downward to press the top of the glue storage cylinder 100.

[0080] When the ring-shaped adjustment knob 303 is turned in the opposite direction, the glue cartridge pressure block 302 will slide upward to release the glue storage cartridge 100.

[0081] In this embodiment, the glue storage cylinder 100 has an upward-facing glue storage cavity 100a; the glue cylinder pressing block 302 has an air inlet channel 3021 communicating with the top opening of the glue storage cavity 100a. Further, the bottom of the glue cylinder pressing block 302 has an annular sealing gasket 304 for abutting against the glue storage cylinder 100. High-pressure gas is supplied through the air inlet channel 3021, which can downwardly compress the glue material in the glue storage cavity 100a, causing the glue material to flow downwards.

[0082] Optionally, the outer wall of the ring-shaped adjustment knob 303 is provided with an anti-slip protrusion 3031 to prevent slippage when turning the ring-shaped adjustment knob 303, thereby improving the user experience.

[0083] In summary, the horizontally detachable injection valve provided by this utility model has the following advantages:

[0084] ① Replacing the glue storage cylinder is quick and easy:

[0085] The side-disassembly design avoids disassembling all components above the glue storage cylinder 100, greatly reducing workload and working time.

[0086] ② Reduce glue dripping:

[0087] The horizontal disassembly method reduces the time spent moving the glue storage cylinder 100 up and down during disassembly, thereby reducing the possibility of glue dripping downwards. This effectively keeps the glue dispensing assembly 1 clean, extends the equipment's service life, and improves the equipment's hygiene.

[0088] ③Independent heating control:

[0089] Independent control of runner heating and glue cylinder heating facilitates rapid maintenance and production resumption, avoiding glue blockage caused by complete loss of heating.

[0090] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
